    Abstract

    Because exoskeletal assistive devices are worn directly by a person, enhancing cooperation is important. However, existing assistive devices have problems in terms of their cooperation with human behaviors. This is because existing assistive devices are driven by estimating the wearer’s movement intention based on predetermined movement time and device angle information. Although these methods are expected to work as expected, in practice, it is difficult to achieve the expected behavior. Therefore, an assistance method is required to reduce such misalignment with time and misalignment between the device and wearer. Therefore, this study focused on the viscoelastic properties that generate force in response to movement and are expected to enhance coordination. In a previous study, the authors confirmed the effects of viscoelastic properties or an assistive device with variable stiffness. However, viscous characteristics during movement have not been considered. In this study, we aimed to improve the coordination by focusing on the viscous characteristics. The viscous torque outputs in response to the angular velocity are expected to be driven in response to actual human motion. In this study, the viscous torque was calculated as the product of the command viscosity coefficient and the joint angular velocity and was applied to a lower-limb exoskeleton-type assist device equipped with a magneto-viscous fluid brake and a planetary gear mechanism. In addition, a viscous command that changes the torque according to speed (proposed method), a time command that changes the output value according to the passage of time, and an angle command that changes the command value according to the angle information of the device were applied to the assist device, and surface EMG measurements and command signals were compared. The target movement was a seated movement, and the left and right vastus medialis and semimembranosus muscles were measured. More than half of the subjects showed a decrease in myopotential for five subjects for all three command methods, confirming the effectiveness of the viscous command.

    Abstract

    In recent years, the number of pipes that have exceeded their service life has increased. For this reason, earthworm-type robots equipped with cameras have been developed to perform regularly inspections of sewer pipes. However, inspection methods have not yet been established. This paper proposes a method for anomaly detection from images in pipes using Generative Adversarial Network (GAN). A model that combines f-AnoGAN and Lightweight GAN is used to detect anomalies by taking the difference between input images and generated images. Since the GANs are only trained with non-defective images, they are able to convert an image containing defects into one without them. Subtraction images is used to estimate the location of anomalies. Experiments were conducted using actual images of cast iron pipes to confirm the effectiveness of the proposed method. It was also validated using sewer-ml, a public dataset.

    In a virtual reality (VR) space, wearing a head-mounted display can help with the visualization of objects; however, users cannot experience realistic tactile sensations. Recently, several force feedback devices have been developed, including wearable devices that use straight-fiber-type pneumatic muscles and magnetorheological fluids. This allows the devices to render elastic, frictional, and viscous forces during spatially unrestricted movement. Nevertheless, a problem remains in that previous devices could handle many bilateral upper limb movement tasks. Therefore, this study aims to develop a device that can handle movements that interact with both arms. Based on experiments concerning the pushing motion in a VR space, the influence of the pseudo force sense was determined to not be small. In addition, we confirmed that the force sensation presented by this system was more realistic when the robot was operated with both arms than when operated with the right arm.

    It is estimated that 250 million visually impaired people reside worldwide, and this number is expected to increase. Even though Braille blocks and guide dogs are used to guide the visually impaired, availability of installation location and cost are some of the major issues in implementing the same. Therefore, there is a need for a device for personal guidance that does not limit the location of use. Therefore, this study focuses on force-sensing presentation using the reaction force of air jets. The proposed white cane-type force-sensing device consists of a white cane, an air pressure source, solenoid valves, and a nozzle is attached to the white cane to inject compressed air. The reaction force obtained at the time of jetting generates a moment in the hand of the user, presenting force perception. Here, as a part of an initial study of the device, the effectiveness of the directional presentation, an obstacle avoidance experiment using an ultrasonic sensor, and a demonstration experiment of guidance were conducted.

    In this study, we propose a method to reduce the traveling load by designing a distributed robot arrangement that considers the shape of a pipeline for a cabled in-pipe mobile robot. The objective of this study is to establish a method to reduce the friction acting on the wires of a self-propelled in-pipe mobile robot and develop a robotic system that can inspect long-distance pipes. This study contributes the purpose of this research in that it proposes a model for estimating the tension acting on the wires of a mobile robot in a pipe and describes a method for reducing the traveling load using a distributed arrangement of robots. The friction acting on the wires in the bent pipe becomes a load for the robots moving in the pipe while towing the wires. Therefore, it is difficult for these robots to inspect complex, long-distance pipelines. Furthermore, we clarified the factors that cause friction forces in long-distance pipes and modeled and quantified the friction forces acting on the wires in the pipes so that each factor could be addressed. Using this model, we propose a distributed deployment method, in which multiple mobile robots are deployed. By driving two robots separated by a distance, we confirmed that two robots could move at 2.5 mm/s in a pipeline that could not be moved by a single robot. Moreover, we proposed a method for controlling the robot according to the load acting on it and confirmed that the robot equipped with this control could inspect a narrow pipe with an inner diameter of 108 mm, where a load of approximately 340 N acted on the back end of the robot, with an efficiency that was approximately 1.7 times higher. This result has the potential to enable the configuration and control of robots, which would be difficult to achieve using conventional methods.

    In this letter, we describe simulations and experiments on the occurrence of cavitation with an instantaneous force generation mechanism based on the motion of the mantis shrimp. This study aims to strengthen the striking force of the developed mechanism by realizing the mechanism of cavitation occurrence. This letter presents a motion and cavitation model for the developed mechanism and provides the results of the simulations and experiments considering the occurrence of cavitation. In previous studies, mantis shrimp have been shown to have two consecutive impacts on a hard object with cavitation in water. However, no robot can imitate the striking mechanism of the mantis shrimp and replicate two consecutive impacts. In this study, the mechanism was designed and developed based on a mantis shrimp model. From the experiment, it was observed that the developed mechanism caused cavitation only at the point of impact, rather than during arm swing. This result suggested that the striking force was strengthened, providing insight into the striking mechanism of the mantis shrimp.

    Recently, force feedback devices have been developed to improve the virtual reality (VR) experiences. However, most conventional force feedback devices target the upper limbs. In addition to achieving force feedback to the upper limbs, realizing force feedback to the lower limbs will make it possible to realize an experience in the VR space, which would not be achieved by force feedback to the upper limbs alone. The authors have elucidated the perceptual characteristics of the human dropping sensation to present force feedback to the lower limbs. In this study, we develop a pair of wearable force feedback shoes that can realize the falling sensation in the VR space. The proposed device meets the required specifications for descent height and acceleration to render the falling sensation. Furthermore, we confirm the usefulness of the theoretical equation by measuring the basic characteristics of the developed device.

By realizing force feedback to the lower limbs, it is possible to realize an experience in VR space that cannot be achieved by force feedback to the upper limbs alone. Therefore, in this study, we developed a lower limb force feedback device based on a physical model of the human lower limb. The output torque of the developed device that met the target torque by the experiment was confirmed. The device was then experimented with to determine if it could reproduce an impact force similar to that of a soccer pass as an initial study. The results suggested that even a low torque of 10 Nm could reproduce a soccer pass.

    Because information transmission by force is a vector quantity with magnitude and direction, it can directly affect humans. However, most existing force feedback devices are stationary, and their movement is restricted. On the other hand, wearable force-feedback devices induce a strange feeling, as they must support the reaction force of the presented force at the body fixing part. Therefore, in this paper, we propose a posture guidance method using force feedback provided by air jets. Specifically, for table tennis movement guidance, we developed a prototype with two degrees of freedom using a table tennis racket. We also conducted a hand posture guidance experiment and confirmed that the proposed method can guide the wrist posture without disturbing the wearer's movement.

    There is an urgent requirement to solve the problem of global warming. The sea ice beneath the Arctic Ocean strongly affects the global climate. However, it has not been fully explored. The range of Autonomous Underwater Vehicles (AUV) used for under-ice exploration is limited owing to their short communication range. To solve this problem, we propose a communication relay system that uses a sea ice drilling robot. We conducted excavation and gripping experiments on actual sea ice to study the parameters and control methods required to design a sea ice drilling robot. The required specifications of excavation and propulsion units were obtained from the experimental results, and a recovery method was developed to address drilling failure.

Short-fiber oriented rubber, i.e., rubber containing oriented short fibers with lengths of 3 mm, has anisotropy in the direction of fiber orientation. In a previous study, it was shown that short fiber-reinforced artificial muscles made of short-fiber oriented rubber can achieve up to 17% shrinkage. However, in that study, characteristics other than the amount of shrinkage were not measured, the basic characteristics of the developed artificial muscle were unclear, and the shrinkage ratio was smaller than that for existing straight-fiber-type artificial muscle. In the present study, we developed a new method for fabricating short-fiber oriented rubber and measured the tensile characteristics in the direction of fiber orientation and vertical to the orientation direction. Moreover, we developed an elongation-type artificial muscle from the rubber sheet and measured its elongation characteristics. Test results indicated that the fabricated rubber sheet had anisotropy. They also indicated that the anisotropy increased with the fiber concentration and that the fiber restraint acted not only in the orientation direction but also in the vertical direction. Furthermore, the developed elongation-type artificial muscle was three times more anisotropic in the ratio of axial changes to diametral changes. On the basis of these results, we expect to develop an automated production method for soft actuators.

    For space rockets, a rotating mixer is used to produce solid fuel. However, mixing with the rotary mixer is subject to high shear forces that limit the equipment drive. In a previous study, the authors developed a new production method using a pneumatically driven peristaltic mixing pump that simulates the intestine and a sensing system with pressure and flow rate sensors. Solid rocket fuel was successfully produced by a small pump unit. In this study, mixing experiments of solid propellant consisting of several types of powders, including metal powder and highly viscous fluids were conducted using a pump unit with a volume size eight times larger than that used in the previous study. In this experiment, mixing was performed with the materials packed in a plastic bag to increase efficiency. This reduces the contact area between the rubber tube and the contents of the device. Because only part of the mixing process is reflected in the behavior of the device, it is difficult to see differences in the sensor values, and it is unknown whether existing methods can be applied. The results of the experiment showed that the existing sensing system could be used to confirm the differences in characteristics due to the mixing process based on the time series data of air pressure and flow rate. By using Gaussian mixture model, which is a type of clustering, the mixing state was roughly binary discrimination from the acquired sensor values. This suggests that it is possible to estimate the mixing degree in large pumps using existing systems.

    Various haptic devices for application to virtual reality have been developed. Most of them have to be stationary on a desk, thus users cannot move around. To overcome this shortcoming, we propose a wearable force feedback device that uses air jet. In this paper, a prototype for hand position guidance which is able to provide force in any direction is developed, and its performance to guide the wearer’s hand is evaluated by experiments.

    With the diversification of robots, modularization of robots has been attracting attention. In our previous study, we developed a robot that mimics the principle of human joint drive using a straight-fiber-type pneumatic rubber artificial muscle ("artificial muscle") and a magnetorheological fluid brake ("MR brake"). The variable viscoelastic joints have been modularized. Therefore, this paper evaluates the basic characteristics of the developed Joint Module, characterizes the variable viscoelastic joint, and compares it with existing modules. As basic characteristics, we confirmed that the Joint Module has a variable viscoelastic element by experimentally verifying the joint angle, stiffness, viscosity, and tracking performance of the generated torque to the command value. As a characteristic evaluation, we verified the change in motion and response to external disturbances due to differences in driving methods through simulations and experiments and proved the strength of the variable viscoelastic joint against external disturbances, which is a characteristic of variable viscoelastic joints. Based on the results of the basic characterization and the characterization of the variable viscoelastic drive joint, we discussed what kind of device the Joint Module is suitable to be applied to and clarified the position of the variable viscoelastic joint as an actuator system.

    This paper describes the development of a compact pneumatic valve that can obtain a high flow rate in a periodically pneumatically driven pipe-moving robot. Plumbing facilities around the world have fallen into disrepair in recent years. Pneumatically driven mobile robots are widely used as an inspection method due to the small inner diameter and complicated shape of the pipes. Various types of robots have been studied, such as earthworm, inchworm, and spiral tube robots. However, these robots are driven by existing pneumatic valve technologies, such as needle-type and solenoid valves, which limit the use of small mobile robots. Small pneumatic valves have a low flow rate, and the entire system is complicated because multiple air pressures are controlled by multiple electrical systems. Thus, focusing on the structure and periodic motion of the ball valve, we developed a pneumatic valve that can periodically apply pressure to multiple pneumatic actuators using only rotational motion with one degree of freedom. We also applied this pneumatic valve to a wave propagation robot and discussed the theoretical running speed of the robot with this valve.

    In this paper, it is proposed a grease dust cleaning mechanism using a planetary gear mechanism to remove accumulated grease in ventilation ducts.In existing research, cleaning robots have been developed to remove dust from air-conditioning ducts. The robot successfully removed dust from the ducts by rotating and scraping the brushes and using air pressure. However, no cleaning mechanism has been developed to remove the highly viscous grease that adheres to the ventilation ducts installed in restaurants. Thus, it is difficult to clean the oil and dust ducts, which are impenetrable.Therefore, in this paper, the authors propose a grease-cleaning mechanism using a planetary gear mechanism for cleaning grease from round ducts. This mechanism cleans the inside of the pipe by scrubbing off the grease from the walls by the rotation and revolution of the brush. This paper describes the selection of the cleaning mechanism, the modeling of the brush trajectory, the control method, and the evaluation experiment of the control method. The evaluation experiment of the control method confirmed the validity of the model and the fact that the brushes made contact with the entire inside of the pipe. This shows the possibility that the inside of the pipe could be efficiently cleaned by the intermittent collisions of the dispersed brushes.

    In this study, the authors comprehensively evaluated the traveling performance of a flexible pipe inspection robot (PI-RO) that can actively output both propulsion and traction forces. Household pipes must be frequently inspected for cracks and corrosion to ensure continuous provision of water and gas. As these pipes are essential for our everyday life, it is difficult to suspend their usage for long periods; hence, inspection should be conducted for short durations. In addition, inspecting entire pipelines using existing methods is challenging because the pipes are constructed over long distances and have complex structures. Therefore, we developed a flexible robot that can actively output propulsion and traction forces to inspect long-distance complex pipelines, such as household pipelines. Herein, we describe the flexible structural design of a PI-RO that inspects thin one-inch pipes (inner diameter of approximately 28 mm) typically present in household piping. We also evaluated the characteristics of each PI-RO unit. Finally, we confirmed that the PI-RO is not significantly affected by the traveling environment, such as long distances and complex small-diameter pipes, by conducting traveling experiments on small pipes (inner diameter 28 mm) and long-distance (up to approximately 11.7 m) complex pipes composed of horizontal, vertical, and 90° bend pipes.

    We propose herein a method for estimating the mixing state of the contents of a peristaltic continuous mixing conveyor simulating the intestine, developed for mixing and conveying powders and liquids. This study serves to improve a previously proposed method for estimating the mixing state using a logistic regression model with the pressure and flow rate sensors installed in the device as inputs. Moreover, the estimation accuracy of the proposed method is better than that of the previous method. The generalizability of the proposed method is evaluated for four conditions in which the feeding order of the contents, powder, and liquid are changed. The feeding order is as follows: powder first, liquid first, and powder and liquid alternately. As a result, a highly accurate estimation of mixing is achieved under the condition wherein the powder component is in the unit adjacent to the lid, but not under the condition wherein the liquid component is fed first. It is speculated that this is because the movement of the powder component inside the device is more easily reflected by the pressure and flow rate sensors installed in the device than in the liquid component.

We determined the required specifications of the robot, constructed a model of the cleaning brush, and developed grease samples. We also conducted experiments to evaluate the performance of the cleaning tools in cleaning grease with different materials, bristle shapes, and rigidity. As a result, it was found that the brush-type could scrape the grease off the cleaning surface and adsorb more grease between the bristles of the brush than the sponge-type. It was also confirmed that the contact area of the brushes affected the cleaning performance. The brush composed of nylon bristles showed the highest cleaning performance at 94%.

    The results of an excavation experiment in an actual sea area using the earth worm type seabed exploration robot are reported in this paper. The robot tested in the experiments is SEAVO II, which has been developed by the authors. Seawater-resistant processing was applied to the SEAVO II, and field experiments were conducted on the coast of Izu Oshima island. Four types of experiments were conducted: vertical excavation in sand, gravel, and water, and horizontal excavation in sand. In the vertical excavation on sand, the SEAVO II successfully excavated 490 mm, which is the same level as that of the previous studies. However, although the excavation was difficult and the excavating distance was limited to 100 mm or less for the other three conditions, the issues in each environment could be clarified.

    In this study, we evaluate the dropping sensation for the development of a wearable lower limb force feedback device that can render both dropping and walking sensations. The developed device can render the dropping sensation at a smaller height than in reality by decelerating and stopping descent during the rendering of the drop image. Considering the user will be walking with the device, a smaller device height leads to better safety. The purpose of this study is to clarify the required specifications of the height of the vertical range of motion of the platform part, and the feasibility of the concept of rendering the dropping sensation. For this purpose, the dropping sensation for the difference in human acceleration time and human deceleration acceleration was evaluated. The results showed that the rendering of the dropping sensation required more than 0.41 s of descent at an acceleration of approximately 1377 mm/s2. Moreover, the dropping sensation and sense of reality were not impaired, even when the platform part of the foot was decelerated. This result indicates that the device can be made smaller.

    Investigation of the lunar subsurface environment is expected to lead to the elucidation of the origin of stars and the discovery of new resources. However, there are still many unknowns in this regard. In a previous study, we developed a drilling robot for lunar exploration and succeeded in drilling vertically up to 938 mm. However, control methods for the robot have not been studied in detail so far, and the grasping state of the propulsion unit during drilling has not been observed. In the study described in this paper, threshold coordination method for the current of the propulsion unit's motors is introduced to achieve effective hole grasping and propulsion. Subsequently, gripping force and penetrating force characteristics of the propulsion unit are tested to understand the grasping state of the propulsion unit during drilling based on the current value and the angle information of the motor. Finally, in-pipe propulsion and excavation experiments were conducted. From the experimental results, we concluded that the proposed control method can be used to grasp the hole with changing hole diameter and monitor the grasping state of the propulsion unit in the hole.

    We developed a robot generating instantaneous force inspired by the smashing mantis shrimp, and conducted dynamic analysis using the mechanistic model. We compared the performance with and without the elastic elements of the exoskeleton to examine the contribution of each spring element. Previously, we confirmed the operation of the proposed mechanism of the shrimp-inspired-system. Because the effectiveness of the mechanism has not fully been examined as an integrated system of elastic components, here we further performed the rigorous numerical simulation using the model otherwise understanding would be limited in the physical robot. From the numerical results, it was confirmed that the proposed mechanism including the spring shortened the time to strike by 0.737 times and increased the impulse at the time of strike by 1.702 times compared with the mechanism using only pneumatic artificial muscles. The results of the simulations demonstrated the interaction between the pneumatic artificial muscles and the elastic elements of the exoskeleton. Our findings can give an insight into the integrative design of the artificial muscles and elastic mechanisms by capitalizing on a design evolved in nature.

    In a virtual reality (VR) space, wearing a head-mounted display can help with the visualization of objects although users cannot experience realistic tactile sensations. Recently, several force feedback devices have been developed, including wearable devices that use straight-fiber-type pneumatic muscles and magnetorheological fluids. This allows the devices to render elastic, frictional, and viscous forces during spatially unrestricted movement. However, during friction and viscosity rendering, the elasticity of the artificial muscle is influenced by the elastic element of the muscle, preventing proper presentation of the force. Therefore, this study proposed a clutch mechanism to switch the force presentation of elastic elements by the contraction of artificial muscles. The mechanism was incorporated into a wearable four-degrees-of-freedom force feedback device, and its elastic, frictional, and viscous force feedback performances were quantitatively assessed via fundamental property experiments. Furthermore, a VR space was constructed to present the operator with force perceptions of virtual elastic, frictional, and viscous objects within that space, and the system's performance was qualitatively assessed. The results confirmed a reduction in the effect of elastic elements and an improvement in the presentation performance. Additionally, the use of this device in the VR space was confirmed to improve the realism of virtual objects in terms of friction and viscosity.

    <p>In this paper, the authors described the modeling method of the instantaneous force generation mechanism inspired by the striking motion of Odontodactylus scyllarus and the evaluation of the mechanism. Animals use the contraction of living muscle as actuators to perform various movements. Some arthropods produce instantaneous movements by using the combined force of the exoskeleton spring and muscle force. Few reports deal with such an instantaneous force generation mechanism of the combined force in the numerical simulation. Our purpose of this study was to construct the instantaneous force generation mechanism by the combined force of elastic elements of the exoskeleton and pneumatic artificial muscles, inspired by the instantaneous force generation mechanism of Odontodactylus scyllarus. In the previous study, we have confirmed that the instantaneous force generation device and the possibility of generating instantaneous force by the physical model. In this paper, the authors further constructed a model of the proposed mechanism as a translational rotation system and performed a dynamic analysis by numerical simulation, confirming the effectiveness of the proposed model. </p>

    To reduce lower back pain of workers, we developed an assist suit for lumbar support in our previous studies. This suit, called AB-Wear II, has mechanisms to aid muscle strength through the inflating power of artificial muscles and balloon actuators, and reduce compressive forces acting on the spine through leaf springs. However, due to the stiffness of the leaf spring and the soft fabric supporter fixed to the wearer's waist, the device slipped out of place during a lifting motion, causing a loss of assistive force. In this study, a new version, AB-Wear III, was developed. The leaf springs in AB-Wear III are composed of a soft material that allows them to follow a wearer's movements. The leaf spring supports the posture of the spine by applying pressure against the back, and it should also reduce the shear force that causes lower back pain. In addition, a lumbar fixation mechanism using a leaf spring wound in an arc shape near the pelvis was developed to fix the device to the body of a wearer and prevent the device from slipping. Based on the electromyography (EMG) of the erector spinae muscles during a lifting motion while wearing AB-Wear III and a questionnaire, the optimal contact position between the back and leaf spring was found to be 60% of the spine length. At the abovementioned length, EMG was reduced by 16.7% than without the device. Subjective experiments also confirmed that the wearers' endurance was improved and lower back pain was reduced using the device.

    In this paper, the prototype of the assistive suit for lower limbs was developed. The prototype was based on an assist method with joint stiffness and antagonized angle control. The assist method comprises a system consisting of a pneumatic artificial muscle and a pull spring, which changes the joint stiffness and the antagonized angle to correspond to the movement phase and aims at coordinated motion assistance with the wearer. First, the characteristics of the developed prototype were tested. It was confirmed that the measured value of the prototype followed the target value in the relationship between torque and angle. In addition, there was hysteresis in the measured value, but it did not affect the assist. Next, the evaluation of standing-up and gait assist by measuring electromyography (EMG) of the knee extensor muscle was conducted using the prototype. In all subjects, a decrease in EMG due to the assist was confirmed. In one subject, the maximum decrease rate at the peak of the EMG was about 50% for standing-up motion and about 75% for gait motion. From the results of these assist evaluations, the effectiveness of the assist method based on the joint stiffness and antagonistic angle control using the prototype was confirmed.

    <p>In recent years, the aging of pipelines has been severe and has caused fatal accidents. The pipe diameters are small, and the layouts are complex. Pneumatically driven mobile robots have become popular as inspection methods. Various types of robots have been studied, like earthworm-type robots, inchworm-type robots, and spiral-tube-type robots. Typically, they make periodic movements; however, they have challenges because they are driven by existing pneumatic valve technologies, which are limited to small mobile robots. Small pneumatic valves have low flow rates and limit the performance of pneumatic actuators. Therefore, we focused on the structure of the ball valve and periodic motion. Furthermore, in this paper, we developed the Compact Rotary Valve Mechanism for pneumatic mobile robots in pipe inspection, which generates periodic air pressure. </p>

    In recent years, soft robots, such as those with high human affinity and those that excellently imitate the movements of natural creatures, have gained considerable attention. In soft robots, structurally flexible soft actuators need to be used, not conventional motors or hydraulic/pneumatic cylinders. Various types of soft actuators have been developed depending on the driving principle. A pneumatic rubber artificial muscle is a kind of soft actuator that acquires power through injection of a working fluid, such as air, into an elastic structure, such as rubber. In this study, the authors developed an actuator, namely, the straight-fiber-type artificial muscle, which exhibits excellent contraction characteristics. This artificial muscle consists of a rubber tube that contains reinforcing fibers arranged in the axial direction. When air pressure is applied to the rubber tube, the artificial muscle expands only in the radial direction and contracts in the axial direction due to the restraining effect of the reinforcing fiber. While this artificial muscle exhibits excellent contraction properties, it has some drawbacks. One is the difficulty in enclosing the reinforced fibers that have accumulated in the rubber tube, making this artificial muscle difficult to manufacture. In this study, we investigated short-fiber-reinforced artificial muscles that can be easily manufactured. First, a short-fiber-reinforced rubber was prepared, and anisotropy was evaluated via a tensile test. Then, the short-fiber-reinforced artificial muscles were prepared, and their contractions rates were evaluated. The results confirmed that a short-fiber-reinforced rubber can be useful for the manufacture of artificial muscles.

    Welding is one of the forms of nonautomated, heavy labor used in the shipbuilding industry. In the shipbuilding process, the hull is first welded by an industrial automatic welding machine, then irregular welded part correction and welding in narrow places that machines cannot reach are performed by welding workers. Welding operators are required to weld indeterminate objects in narrow working spaces. In addition, it is difficult to perform high-quality welding because the ability to accurately trace a welding line at a constant speed requires a long training period. In this research, a welding training device that assists trainees in skill acquisition was developed. The proposed device, which comprises two magnetorheological (MR) brakes, renders a welding path and restricts welding speed. The MR brakes have a response speed comparable to that of powder brakes, have a high output-to-weight ratio, and are also considered to be suitable for use in welding training devices. A prototype and control strategy were developed, and the performance of the device in actual welding work was evaluated. Results shows that path rendering strategy is possible to present routes with an accuracy of 1 mm or better and speed control strategy can regulate the speed required for welding.

    In this paper, a mechanism for generating an impulsive force by using the distortion of an exoskeleton is described. Pneumatic artificial muscles not only have a high power to weight ratio, but also have a high affinity with the human body due to their use of air pressure. However, pneumatic artificial muscles have a slow stretch response rate due to their viscous properties. Therefore, earthworm type mobile robots and wearable assistive devices using artificial muscles move slowly and have difficulty assisting human movements. We focus on the mechanism of force generation using the distortion of the exoskeleton, similar to what is seen in the punching of a mantis or the jumping of a grasshopper, as a countermeasure against the delay in the response rate of the artificial muscle. In this study, we propose a new mechanism to generate a shooting force by incorporating an element similar to an exoskeleton spring into the antagonistic drive mechanism of an artificial muscle. We designed and developed a prototype then operated it and measured the impulsive force. It was found that the developed mechanism showed similar joint movements through muscle contraction to those of mantis shrimp and grasshoppers. Furthermore, it was shown that the time constant for the maximum strike force was 6.6 N and 63.2 % of the maximum impulsive force was 0.183 s.

    In the study, we propose a negative-pressure-driven soft linear actuator for the fixation part of an exoskeleton. In the study, a concept of the fixation part that is easy to wear with reliable force transmission is first proposed. Subsequently, a negative-pressure-driven soft linear actuator for the proposed fixation method is introduced and prototyped. Finally, basic characteristic experiments are conducted with a prototype. The results indicate that decreases in the pressure increase the actuator's contraction force and maximum contraction. It exhibits a large hysteresis that is approximately 50% at maximum contraction force. Increases in the width increase the contraction force. Increases in the height increase the force and rate of contraction.

    © 2020 IEEE. A peristaltic continuous mixing conveyor that focuses on the mechanism of the intestine has been developed as a technology for the mixing and transport of a solid-liquid mixture and high viscosity fluids. The developed peristaltic continuous mixing conveyor succeeded in the mixing and transport of such mixtures in a previous study. A simple cyclic pattern is currently used as the movement pattern of the system, and the control method can be further improved. In this study, we aim to realize an intelligent mixing and generation of a conveyor pattern based on intestinal movement. The mixing state of content during activation was estimated through machine learning. The results from the time-series measurement data show that an internal mixing state in three units of the peristaltic continuous mixing conveyor was estimated.

    This study proposes the development of a locomotion robot using a deformable dielectric elastomer for actuation without pre-stretch. Electroactive polymers (EAPs) that are driven by electrical stimulation have recently garnered attention. Among EAPs, dielectric elastomer actuators (DEAs) are focused herein. DEAs have a structure wherein a dielectric is sandwiched between elastic electrodes. The performance of the DEA depends on the relative permittivity, Young's modulus, and the applicable voltage of the dielectric material. DEAs are usually used with pre-stretching, because of the material properties of the dielectric, which requires a large stress in the initial stage of extension, and the increase in the displacement of DEAs with the application of pre-stretch. However, because rigid frames are generally used for prestretching, there are few DEA applications that utilize their flexibility. Therefore, we focused on slide-ring materials (SRMs) as new dielectric materials. SRMs are polymer materials in which the cross-linking points move freely, and having excellent properties as dielectrics for DEA applications. Thus, pre-stretching is not required, and applications utilizing the flexibility of DEAs is possible. In previous research, a bending unit that did not require pre-stretching was manufactured by attaching non-stretchable tape to one side of the DEA using an SRM as the dielectric material. In addition, a locomotion robot with a bending unit was developed, and it was confirmed that the robot achieved locomotion because of a phase difference between the units. However, the basic characteristics of the bending unit and locomotion robot were not discussed. Therefore, in this research, we measured the frequency characteristics of the bending unit alone and demonstrated the locomotion of the robot.

    During overhead work, workers need to keep raising weights of approximately 2 to 4 kg with the muscular strength of their upper limbs, and the burden of this work is high. Therefore, we developed an assistive device, named TasKi, using a self-weighted compensation mechanism to reduce the burden on upper limbs during overhead work. It can compensate for upper limb weight using the force of a spring in various postures of the upper limbs, without a battery. In this study, to provide effective assistance to many users, we clarified the crucial assistance and parameter adjustment range of settings corresponding to physical differences. First, the assistive force value of TasKi to reduce the work burden of each user was confirmed via a subjective evaluation experiment and myoelectric potential-measurements. Next, we conducted a test survey of TasKi users and investigated the relationship between physique and the wearing feeling. According to the survey, 80% of the subjects provided favorable opinions on the assistive method used by TasKi. Finally, we had subjects of various physiques wear the device and investigated the relationship between physique and the wearing feeling with respect to shoulder joint movements. It was observed that the subjects with greater shoulder widths experienced difficulties when moving in the direction of internalexternal rotation because of the small size of TasKi. The influence on the ease of motion and perception of size was less in the direction of flexion-extension and adduction-abduction motions.

    Globally, lower back pain is a serious problem. For workers, it not only causes health problems but also has social and economic influences. Lower back pain could be attributed to burden on people's waists when they handle heavy objects. Ministry of Health, Labour and Welfare in Japan recommends squat lifting, a method of lifting objects with a smaller burden on waist. On the other hand, squat lifting is not commonly used because it requires deep bending of knees to lift an object, leading to a larger work load. Therefore, a leaf-spring type power assist suit for legs has been developed in order to assist squat lifting. However, if the fixing performance of a preceding machine was enhanced, a leaf spring could impede the bending of knee joints during gait motion. In the present study, we developed a power assist suit for legs using a slide mechanism. A leaf spring was chosen so as to meet a target assist torque determined by a motion analysis for lifting objects. In addition, we made a prototype machine with slide mechanism. EMG measurement of the thigh muscle during lifting actions using the prototype machine showed a decrease of up to 46%. It was also confirmed that a machine with slide mechanism could realize a more natural gait than a machine without it.

    © 2020 IEEE. Powders are used in various devices, including printing presses. To prevent agglomeration, the powder in a printing press must be conveyed by a technique with low shear force and no temperature rise. The present study introduces a powder-conveyance robot based on peristaltic movements of the human intestinal tract, and evaluates it on the powder used in printing presses. The human intestinal tract is non-skeletal, soft and plays an important role as soft actuation. In our previous study, the peristaltic-motion type conveyor transported the powder at high speed (81.5g/s) without aggregation. However, the behavior of the inner tube after changing the characteristics and wavelength of the unit is unknown. This research investigates the conveyance amount and the inner-tube movement of a peristaltic-motion type conveyor unit operated at different wavelengths and operation intervals. By simultaneously mapping each parameter, we aim to increase the speed conveyance in future work.

    © 2020 IEEE. Recently, various types of soft actuators and their applications have been studied in the search for alternatives to conventional robots. In particular, pneumatic soft actuators have the advantages of a light weight and high power. One of the applications of such soft actuators is fusion with flexible structures. However, because these actuatable flexible structures consist of rubber, silicone, or flexible resin, it is difficult for them to support their own weight, owing to the effect of the square-cube law in the case of an increasing size. We have developed actuatable flexible structures. LayerCAKE is a laminated open-cell and closed-cell foam structure, where cell foam is a lightweight and flexible material that can be used to realize large actuatable flexible structures. LayerCAKE is actuated using the concept that open- and closed-cell foams contract differently when they are vacuumed. In this paper, the design of a large LayerCAKE mechanism is described and tested. A large actuatable flexible structure of size approximately 1250 mm that bends in a vertical direction was realized.

    © 2020 IEEE. Actuators known as pneumatic artificial muscles are superior for practical use because they do not require maintenance, are inexpensive, and can be assembled with a drive unit and an energy generation unit independently. However, because these actuators expand greatly in the radial direction when pressurized, one problem is that they occupy a large amount of space and consume a significant amount of flow. In this study, we propose a space-saving, constant-axis fiber-reinforced artificial muscle that does not expand and also takes advantage of the benefits of pneumatic artificial muscles. Hence, this paper reports on the driving principle of the proposed noninflatable pneumatic artificial muscle and the basic characteristics are then confirmed using a prototype.

    © 2020 IEEE. Force feedback devices are attracting attention as a way to apply virtual and augmented reality to entertainment, sports, and rehabilitation. We previously developed a force feedback device using pneumatic artificial muscle and a magneto-rheological fluid clutch. However, problems occurred, such as an increase in the weight of the device and complications in the control system. To solve these problems, a new force feedback method using an elastic spring and a magneto-rheological fluid clutch was therefore proposed. In addition, the force feedback characteristics of the force feedback method were modeled. A 1-degree-of-freedom force feedback device using the new force feedback method was also developed. The model characteristics of the force feedback for rendering the elasticity using the device were confirmed experimentally.

    © 2020 IEEE. We attempt to generate traveling waves by applying a dielectric elastomer actuator (DEA) with a sliding ring material (SRM). A normal DEA using silicon or acrylic rubber requires pre-stretching with a rigid frame to obtain a large displacement, owing to the material properties of the dielectric, which require a large stress to be applied at the initial stage of the extension. A DEA using an SRM does not need to be restricted by a rigid frame and can be expected to generate large displacements and complex motions while maintaining its flexibility. In this paper, we report the development of a traveling wave generator as an initial study. Through experiments, the developed DEA was confirmed to function as an actuator without pre-stretching. In the future, in addition to determining the optimum phase difference, frequency band, and shape of the constrained parts to increase the speed, we plan to develop a mobile robot utilizing a DEA traveling wave with a mechanism that would allow the units to overlap.

    © 2020 IEEE. In this paper, we describe the performance of a pneumatic artificial muscle integrally molded by a 3D printer that can mold materials with different stiffnesses.In the recent years, soft and hard materials can be integrally molded as the performances of 3D printers improve. For this reason, attention has been focused on the integral molding of actuators by using 3D printers. In this study, an artificial muscle is integrally molded by a state-of-the-art 3D printer, and the amount of contraction and contraction force generated are experimentally measured. In particular, the integrally molded artificial muscle formulated in this study is a pleated artificial muscle that does not require high material stretching performance. When the stiffness of the leaf spring material constituting the 3D printable artificial muscle is changed in a stepwise manner, the generated contraction amount and force were measured. From these measurement results, the usefulness of this actuator was confirmed by comparing the generated force with that of a pneumatic piston with the same inner diameter.

    © 2020 IEEE. In recent years, expectations for low-cost and high-frequency rocket launches for space exploration have increased. Solid fuel rockets are small, inexpensive, and easy to handle. However, in the production of solid fuel, the mixing process and the transportation process are separate batch processes, leading to an increase in maintenance costs and disposal costs. In addition, being a manual process, it is difficult to manufacture large amounts simultaneously in a safe method. The authors have developed a mixing and transportation device that simulates the movement of the intestinal tract by using an elastic duct and a low pneumatic drive. In addition, actual fuel production has been carried out in a mixing and transporting experiment using this device. The effectiveness of this device has been exhibited from the combustion test of the produced fuel. In this paper, we present a high-quality and efficient method of mixing and transporting solid propellant material. This is a mixing of solid and liquid achieved by peristaltic movement done in real-time by adjusting the mixing degree of the mixture inside the device. The degree of mixing is determined by the solid propellant's volume and viscosity change. Therefore, we first investigate whether the content volume can be detected when the rigid bodies with different volumes are inserted. Next, we focus on the change in the viscosity of the mixture that occurs during the mixing process. We also examine the viscosity of the contents when fluids having different viscosities are inserted.

    Copyright © 2019. The Authors. Published by Elsevier Ltd. All rights reserved. In the shipbuilding industry, welding is one of the forms of nonautomated heavy labor, and the welding operator is required to weld indeterminate objects in a narrow working space. Therefore, it is difficult to use large equipment, such as industrial robots. In addition, it is not easy to perform high-quality welding, because tracing a welding line accurately at a constant speed requires a long training period. In this research, the aim was to develop a welding assist device that can be applied to a welding environment. The proposed device fixes to the welding surface by magnetic force and assists semiautomatic welding with a magnetorheological (MR) brake. MR brakes have a sufficient response speed compared with powder brakes, have a large output weight ratio, and are considered to be suitable for welding assistance. In this work, a strategy for control of path rendering and speed restriction by MR brakes is proposed. Its effectiveness was confirmed by experiments with a prototype.

They are classified into desktop and wearable types. A wearable 1 degree of freedom force feedback device using magnetorheological fluid brake, magnetorheological clutches, and pneumatic artificial muscles has been previously developed and it was confirmed that the device can render elasticity, friction, and viscosity. In addition, a wearable 4 degrees of freedom force feedback device using magnetorheological fluid clutches and pneumatic artificial muscles that can render elasticity was also previously developed. However, it was not established that the device could render friction, and viscosity using magnetorheological fluid clutches and pneumatic artificial muscles. In this report, it is confirmed that such a device can render friction and viscosity using magnetorheological fluid clutches and pneumatic artificial muscles without the need for magnetorheological fluid brake.

    In this study, we made the assumption that the feeling of a firm handshake is related to the stiffness of the elbow joint and we performed handshake experiments under variable stiffness conditions to verify the assumption. EMG signals were recorded to be used as an evaluation. Then human-robot handshake experiments were performed utilizing a handshake manipulator proposed in the previous research. The joint of the manipulator was driven by antagonized artificial muscles, which are considered to be soft actuators designed to mimic the movement of real human muscles. The muscle activations of the subject were compared when the subject shook hand with the experimenter and the manipulator. And it has been demonstrated that even though the subject was not aware of the experiment conditions, the muscle activations are higher in the firm handshake condition in both human-human handshake and human robot handshake experiments, which indicated that firmness of handshakes are related to the stiffness of the joint and the EMG signals can used as an evaluation method.

    &lt;p&gt;Seabed mineral resources were found on the bottom of the ocean. To utilize these resources, it is necessary to collect and analyze samples. Therefore, we intend to develop a seafloor robotic explorer that can excavate and sample the seafloor soil. In a previous study, we developed a drilling robot and experimentally demonstrated the ability of this robot to produce curved boreholes with a turning radius of 1,670[mm], and a depth of 613[mm] in land environment. However, an underwater excavation has not been successful. It is necessary to improve the gripping torque and to reduce the drilling resistance for underwater excavation. In this paper, we present a propulsion unit with the setae that imitates an earthworm&#039;s setae. As a result, the drilling robot succeeded in drilling into the ground while underwater. In addition, we aim to reduce the drilling resistance. We adjusted the penetration speed and the rotational speed of the drilling robot based on the drilling properties of underwater ground. We also consider the shape of the earth auger to reduce the drilling resistance. As a result, we succeeded in reducing the drilling resistance, which both lowered the excavation energy by 39.2% and reduced the completion time. &lt;/p&gt;

    In this study, a handshake manipulator with variable viscoelastic joints was proposed. The variable viscoelastic joint system comprised of antagonized artificial muscles and a magneto-rheological fluid brake. This joint system resembles the characteristic of real human joint. The objective of this study is to evaluate the proposed manipulator's effectiveness in the research of human-robot physical interaction and to verify that by adjusting the viscosity and stiffness of the joint it is possible to create handshakes with different feelings. In this research two sets of experiments were conducted; the first set of experiments was to conducted on the manipulator alone in order to test the performance of the manipulator. And the second set of experiments was the subjective evaluation of the manipulator when subjects shook hand with the manipulator under variable viscosity and stiffness conditions. The results of these experiments indicated that the manipulator was suitable for doing research on human-robot handshake, and the variable viscosity and stiffness of the elbow joint did create distinctive feelings to the subjects.

    A dielectric elastomer actuator (DEA) is a soft actuator with low manufacturing cost and high energy efficiency. The structure of a DEA consists of a dielectric material interlayered with elastic electrodes, and DEA expands when an electric field is applied. The degree of freedom of movement of the DEA can be increased by devising the electrode arrangement in DEA. The performance of DEA is determined by permittivity, Young's modulus, and applicable electric field. Material properties including hysteresis loss are also important when a DEA is used as a sensor or high precision actuator. Generally, silicon and acrylic rubbers are used as the dielectric layer. This study focused on the use of a slidering material (SRM) as a more suitable dielectric for DEA than silicone and acrylic rubbers in terms of its dielectric constant and hysteresis loss. In a previous study, a DEA was developed using SRM as a dielectric, and the image correlation method (ICM) was applied to measure the strain distributions in a two-dimensional plane and the basic characteristics of DEA with one pair of electrodes. Here, the strain distribution was measured when the electrodes of the DEA were segmented into several pairs as the next step in the investigation of its basic characteristics. Patterns of electrode arrangements and the amount of DEA prestretching were changed, and strain distribution was measured using ICM.

    Various types of soft actuators have been developed for application in wearable movement-assist devices or soft robots. The authors have developed a straight-fiber-reinforced pneumatic rubber artificial muscle (SF-ARM). The SFARM is composed of rubber that is reinforced with fibers aligned only in the axial direction. When air pressure is applied to the SF-ARM, the reinforced fibers limit the rubber expansion to the radial direction so that the muscle contracts in the axial direction. The SF-ARM contracts by 38% at maximum, and this contraction rate exceeds the contraction rate of the McKibben artificial muscle. However, the SF-ARM is not well-suited for practical use because the strain on the SF-ARM while it is actuated is large which can cause fatigue failure of the rubber. This study focuses on suppressing the growth of cracks using strain-induced crystallization of the natural rubber, to prolong the lifetime of the SF-ARM. Natural rubbers form a crystalline layer in the direction perpendicular to the direction of stretching. This crystal layer effectively suppresses the growth of cracks in the SF-ARM when under strain. Deliberately developing a crystal layer should extend the lifetime of the SF-ARM. First, this study confirmed the formation of a crystal layer under extension of natural rubber (NR) and styrene butadiene rubber (SBR) using wide-angle X-ray diffraction measurements. Next, the strain concentration near the crack was analyzed using finite element method simulations. Finally, fatigue-life tests were conducted with SF-ARMs made of NR and SBR.

    Dielectric elastomer actuator (DEA) is a soft actuator with low manufacturing cost and high energy efficiency; it expands when an electric field is applied. The structure of DEA comprises a dielectric material interlayered with elastic electrodes similar to a sandwich. The performance of DEA is determined by the material of the dielectric layer, which is generally silicon or acrylic rubber. This study focused on investigating the characteristics and various applications of slide ring material (SRM) as a dielectric. SRM is more suitable for use as a dielectric of DEA as compared to silicone and acrylic rubbers in terms of the dielectric constant and hysteresis loss. Several measurement methods of existing DEAs measure only uniaxial deformation. However, the actual DEA strain distribution is not completely uniform. In addition, obtaining the two-dimensional (2D) strain distribution leads to a better understanding of the lifetime and performance of DEA as DEA deforms in 2D practical applications. Therefore, this study measured the strain on the DEA, while changing the load, applied voltage, and number of layers, using the image correlation method, which is a 2D planar measurement method. This measurement confirmed the two-dimensionally spreading strain distribution. The relationship between the stress, strain, and number of DEA layers was also obtained.

    <p>Pneumatic rubber artificial muscle is attracting attention as an actuator having high cooperativeness with human because of its feature of being flexible and lightweight. The authors have developed Straight fiber type pneumatic artificial muscle (SF-ARM), which is a high power, highly displaced pneumatic rubber artificial muscle. Although SF-ARM has excellent contraction characteristics, it has a problem of short fatigue life. Therefore, in this study, focusing on strain-induced crystallization of natural rubber, the fatigue life of SF-ARM has been extended. First, strain-induced crystallization of natural rubber were confirmed by wide angle X-ray diffraction. Next, analysis of strain concentration in the vicinity of the crack was performed by the finite element method. Finally, a fatigue life test of SF-ARM was carried out to confirm the effect of prolonging the fatigue life by using strain-induced crystallization.</p>

    <p>There are many pipe-systems such as a water pipe, a gas pipe and a ventilation duct in a plant, factory and house. The inspection of these pipe-systems is necessary to prevent accidents and malfunctions. However, many pipes are very narrow, and it is difficult for people to inspect directly. In this study, a brush wheel type robot which has the simple and compact drive mechanism and does not need large space to move, is proposed. When moving inside of a pipe, this robot uses the elastic force of a brush wheel to hold the robot in pipe. Additionally, the robot can move a vertical pipe and a curved pipe by replacing the brush wheels. This paper reports the robot's structure, the drive mechanism, the operation principle, the prototype evaluation and three type pipe running experiments.</p>

To realize underwater excavation by SEAVO, it is necessary to move the soft and fluid sedimentary layer of seafloor surface. As a solution, we focused on the setae of earthworm which live in mud and soft soil. Then, we developed the propulsion unit with bristles imitating the earthworm's setae and measured the performance of the setae-attached propulsion unit. Comparing the measurement result of the bristlesattached propulsion unit with the previous propulsion unit, we confirmed the usefulness of the bristles-attached propulsion unit.

    Pneumatically driven wearable assistive devices for walking have been developed recently. These devices can achieve flexible assistance without control; however, they require large and heavy air compressors for activation. In this study, a pneumatically driven source using vibration energy regeneration from walking was developed. The aim was to activate the cylinder using vibrations due to walking and compressed air. A mass element, which is connected to a human body via a spring and a cylinder, vibrates along with the human gait cycle. Next, a prototype was developed and tested. In walking experiments, stored pressure was measured at several gait cycles and masses for comparison. Results indicate that the gait cycle period and masses affect the stored pressure; the highest pressure recorded was 0.08 MPa.

    Marine resources exist on the seabed, and sampling is useful for a detailed study of these resources. In general, a pipe-shaped sampler is used to collect marine resources for investigation. However, this is inefficient for investigating sediments, which are widely distributed, because the sampling range is limited to the pipe penetration part. A wide area exploration can be made possible by deploying multiple robots to autonomously search beneath the seabed. In a previous study, we developed a seabed robotic explorer called "SEAVO" and experimentally demonstrated the ability of SEAVO to produce curved boreholes with a turning radius of 1.67 m, and a depth of 613 mm, in the land environment. However, underwater excavation has not been successful. Reduction in the drilling torque is necessary for underwater excavation. In this paper, we propose a water jetting excavation method to reduce the drilling torque.

    For lunar underground explorations, we have developed lunar earthworm-type excavation robot “LEAVO” and achieved vertical excavation with it. Then, we now wrestle about curving excavation to make the LEAVO be able to collect some samples in particular layer efficiently. To achieve the curving excavation, it is necessary for the LEAVO's excavation unit to excavate target diameter borehole certainly because the LEAVO become to be inoperable in the excessively large or small diameter borehole. To excavate target diameter borehole certainty, in this paper, we develop the “both-ends supported flexible auger” as the LEAVO's flexible excavation unit and carry out its characteristics test. Moreover, we confirm its usefulness in the axis runout check and excavation test.

    Infrastructure pipes require inspection in order to prevent accidents. However, it is difficult to inspect a 1-in-diameter gas pipe because it is long, narrow and complicated. Therefore, an earthworm-type robot was developed to inspect this 1-in pipe. The robot moved by peristaltic crawling with pneumatic artificial muscles and displayed its suitability as a 1-in pipe inspection robot in experiments. However, its speed was extremely slow to be practically utilized. A major cause for this is the small distance covered in a single motion of the robot. Therefore, in this study, we developed an axial extension actuator to increase the moving distance of the robot in a single motion. Furthermore, we installed this new actuator on our robot and made it possible for the robot to change the morphological motion in peristaltic crawling. The experiments with straight and elbow pipes ascertained the importance of morphological change in peristaltic crawling for increasing the speed of the robot. Moreover, in a continuous elbow pipe, the velocity of the proposed robot was 5.5 mm/s, which is 1.3 times faster than that of the conventional robot. Consequently, we confirmed that the speed of the proposed robot was sufficiently fast for inspecting a 1-in pipe.

    This letter proposes a novel hybrid pneumatic power source for the development of a portable pneumatic source. The hybrid pneumatic source achieves a lightweight system by combining two pneumatic sources: one that can generate high pressure/small suppliable flow and one that can generate small pressure/large suppliable flow. In this study, first, the mobility of various pneumatic sources is evaluated by experiments. The evaluation methods involve a small battery-driven compressor, tank, phase change of material, and chemical reaction. From the results, it is clarified that there is no best method because each method has advantages and disadvantages. Then, a hybrid pneumatic source utilizing the result is proposed. Finally, a prototype that has phase change of CO2 and dimethyl ether as a pneumatic source is developed, and the effectiveness of the proposed method is confirmed by experiments.

    In this study, a variable viscoelastic joint system with a clutch for human assistance was proposed. The variable viscoelastic joint system comprised antagonized artificial muscles and magneto-rheological fluid brake. This system enabled the human assisting device, such as exoskeletons, to retain structural softness when compared with the existing devices driven by motor and reduction gear, which could only achieve superficial softness. In addition, a clutch system that provided high back-drivability to the wearer by structurally separating the device from the wearer was proposed. As an initial step in designing the human assisting device, a prototype with the proposed variable viscoelastic joint system for knee assistance is developed. Also, its control method was developed. Furthermore, experiments were conducted to confirm the influence of the proposed viscoelastic joint system and control method on the wearer.

    <p>Recently, assisting human motion with a wearable robot is studied widely. These assisting systems are proposed from various points of view. Our study has proposed an assisting system that the torque, angle, and the viscoelasticity of the joint are variable because the human muscle has the characteristic of variable viscoelasticity. This system consists of antagonized muscle that the stiffness is variable and magneto-rheological fluid brake that the viscosity is variable. Therefore, the system enables the wearable assistive device such as exoskeletons to be structurally soft and to provide the wearer with a high back-drivability. We have proposed the assisting method by changing the viscoelasticity of the device joint according to the viscoelasticity of wearer's muscle. But suitable viscoelasticity of the joint for the assistive motion is not well known. In this paper, an experiment is conducted to examine how the viscoelasticity of the joint affects to human motion when assisting. Also, based on the results from the experiments, we propose the control method for the joint viscoelasticity of the device that responds to the assistive motion and confirm the effects with the experiments. </p>

    © 2018 IEEE. In recent years, because the development of space technology has been increasing for the purpose of improving the social infrastructure, the expansion of space transportation systems based on low-cost and high-frequency rockets is important. Solid propellants used in solid-fuel rockets have properties of the compactness, inexpensiveness, and easy-handling. However, solid propellants are highly viscous slurries and highly explosive. As there is no device capable of continuously and safely transporting solid propellant, the process of manufacturing solid propellant is a batch process. We focused on the movement of human intestines that knead and transport with a small force as part of the development process. In this report, we design a mechanism for the mixing process by using a peristaltic mixing transporting device for efficiency and by automating the equipment. Specifically, we conduct two experiments with samples using an adjusted fluid ratio: A comparison experiment on fluidity and a pressure response experiment. We investigate the possibility of automatic control and efficiency by using the factors of pressure and flow rate.

    <p>The cylindrical rubber is axially reinforced by the fiber and closed by the rigid ends. When the inner pressure is applied to this fiber reinforced rubber cylinder, the diameter expands and the length shrinks. Such the cylinder can be used as the soft actuator, that is, the artificial muscle. In this paper, this problem is analyzed theoretically. Firstly, the differential equation, which is satisfied the cylinder's profile, is derived. Secondary, the solution is obtained as the closed form, when the rubber is soft enough compared to the fiber. Finally, it is found that the profile of the rubber cylinder is given by the incomplete elliptic integral, when the inner pressure is large enough. Moreover, the spring constant, the contraction ratio and the maximum stress are obtained with respect to the length of the cylinder. The spring constant is linearly increasing with the inclement of the initial length of the cylinder. The contraction ratio is increasing with the inclement of the initial length of the cylinder and converged to 54.3%. The maximum stress is related to the elastic modulus of the rubber and is not related to the inner pressure. When the length of the cylinder is through three to five times larger than the initial diameter of the cylinder, the rubber has the small maximum stress and the large contraction ratio.</p>

    Powder-based materials are widely used in various applications such as printing. In printing, low shear force and high-speed conveyance at low temperatures are required to prevent creating defects in materials. In a previous study, we developed a transportation device based on the human intestinal tract that successfully transported highly viscous and solid-liquid fluid mixes and powder material. In this study, we developed a tubular peristaltic conveyor capable of transporting powdered materials in a printer under the aforementioned conditions. The conveyor had a triangular cross-sectional area and a small air chamber to facilitate high-speed peristaltic motion. The performance of the conveyor was confirmed experimentally, and we achieved a conveyance rate of 81.5g/s.

    Recently, low back pain of laborer is social issue in Japan. This problem is caused by excessive load on waist joint or uncomfortable posture of heavy labor, such as lifting up heavy objects. To resolve the problem, we have developed endoskeleton-type power assist suit. In previous study, the design and operation method of the assist suit was designed using simple static model. However, this method is insufficient for designing the assist suit because structure of human body is more complex than the model practically. Therefore, we use the musculoskeletal model to design the assist suit and its operation method in this paper. Firstly, motion of worker is analyzed using 3D motion capturing and this results are applied to musculoskeletal model &ldquo;Anybody&rdquo;. Secondly, with these simulation results, the assist suit and its operation method are designed. Finally, effectiveness of the assist suits confirmed by measurement of electromyography and assistive force.

    In recent years, ventilation equipment has been installed in various structures to draw in outdoor air and circulate indoor air. These ventilation installations have pipes (ducts) through which air flows. If dust accumulates in a duct, it will be carried indoors by the airflow. Dust adversely affects human health, and so these ducts must be cleaned regularly. However, the existing cleaning methods are inadequate for the Ducts having small diameter and many curved points, that are used in houses. Thus, to clean such ducts, we have developed a robot that moves imitating peristaltic crawling. This motion is suitable for moving in ducts because it is stable in curved and narrow pipes. In addition, the robot can move and clean the duct at the same time because it moves forward by holding the pipe walls. In this paper, we outline the development of such a robot. From the results of using the robot to clean the inside of duct, we find a cleaning performance of it.

    In this study, we developed a wall-climbing robot for airplane body inspection. To move on airplane body, the robot needs to move on walls and curved surfaces. A traveling-wave-type, omnidirectional wall-climbing robot that uses magnetic force to adhere could move on such a wall and curved surface. However, magnetic force cannot be used to adhere to airplane body. Therefore, we developed a wall-climbing robot that uses negative pressure suction to adhere and move on airplane body. We performed basic experiments on the robot and designed the robot based on the experimental results.

    Lower back pain is a major health concern worldwide. One cause of lower back pain is the burden on the lumbar region caused by the handling of heavy objects. To reduce this burden, the Ministry of Health, Labour and Welfare in Japan has recommended 'squat lifting.' However, this technique, which supports a large force on lower limbs, is not very popular. Therefore, we aimed to develop a power assist suit for squat lifting. In this paper, we propose a gastrocnemius-reinforcing mechanism. Next, we discuss estimation of joint torque from motion analysis of squat lifting in order to construct a prototype. Finally, we describe the performance of the prototype mounted on a human body. The %MVC of the gastrocnemius while performing squat lifting was reduced by 34% using the prototype assist suit compared with the value without using the suit.

    If pipes with narrow diameters are not well inspected, preventing accidents become difficult. Therefore, we developed a pneumatically powered earthworm-type robot for Half-inch pipes (each having an inner diameter of approximately 16 mm)
    these pipes are extremely difficult to inspect. When the robot travels for a long distance, its speed significantly decreases. When the movement distance of one cycle is small and the inter-operation period is short, the influence of the response delay of the pneumatic actuator increases and the speed decreases. Therefore, we developed a robot whose response delay is less likely to influence the driving speed and that has a large amount of movement per cycle. To create the proposed robot, we developed an extension unit and a grip unit as pneumatic actuators and experimented on pneumatic response characteristics. Also, the driving speed was measured using running tests. This confirmed that the robot's speed increased, and the speed decay owing to the long air tube decreased. The proposed robot will help reduce accidents arising from the corrosion of pipelines.

    In recent years, road collapse accidents due to leakage of aging sewage pipes have become a major social problem. To prevent accidents, the inside of the sewage pipe must be inspected. However, it is difficult to inspect long-distance pipes with diameters of 100 mm or less and curved pipes. Therefore, in this research, we develop an inspection system that uses earthworm movement which can drive steadily over long distances even in narrow spaces. This research involves traveling experiments on straight horizontal pipes, straight vertical pipes, and 90° pipes, and the usefulness of the proposed approach is confirmed. In this report, we present the device to estimate the shape of sewer pipelines and confirm its usefulness by experiment.

    In this study, we developed a 4-degrees of freedom (DOF) force feedback device independent of its operational component comprising pneumatic artificial muscles and magnetorheological clutches. Research and development of force feedback devices is becoming popular in fields such as entertainment, remote operation, and rehabilitation. These areas of research are related to virtual reality and augmented reality. People are focusing their research efforts on force feedback devices that display three-dimensional virtual objects or can provide realistic force sensing as that of stroking the surface of a virtual object. Many of these devices comprise motors
    hence, they are likely to be hazardous in the event of delayed response to an unexpected external force. In addition, their back drivability decreases when the motor output is increased via reduction gears. To solve these problems, we previously developed a 3-DOF force feedback device using pneumatic artificial muscles, which are structurally flexible and have a wide range of stiffness, and magnetorheological clutches. As the next step toward developing a 6-DOF device, we have developed a 4-DOF feedback device.

    Unmanned rescue, observation, and/or research vehicles with high terrain adaptability, high speed, and high reliability are needed in difficult-to-reach locations. However, for most vehicles, high performance over rough terrain reduces the travel speed and/or requires complex mechanisms. We have developed a blade-type crawler robot with a very simple and reliable mechanism, which traverses uneven terrain at high speed. Moreover, the gyro wheel design stabilizes the success of this approach in improving the motion, ensuring robust traversal. The improvement in traveling speed and robustness over uneven terrain by our approach was confirmed by experiment.

    In recent years in Japan, over half of all workers suffered from lower back pain. This has become a social problem that needs to be addressed. To reduce its occurrence, we developed a flexible, high-output waist assist suit called 'AB-Wear' in a previous study. The AB-Wear suit can assist human motion and reduce muscular fatigue of the waist. However, the assistive forces of the device generate compressive forces on the backbone, which have adverse effects on the body. Hence, in this study, we propose an exoskeleton-type AB-Wear equipped with a compressive force reduction mechanism, called 'semi-endoskeleton-type AB-Wear'. This device has a reduction mechanism similar to a flexible flat spring behind the upper body. Because of this structure, this device can generate an effective assistive force. First, we explain the difference between the semi-endoskeleton-type AB-Wear and the previous device. Then, we model the semi-endoskeleton-type AB-Wear because the model is used for its operation. Moreover, its effectiveness is confirmed using musculoskeletal simulation. Finally it is evaluated by measuring surface electromyography (EMG) on a subject's body to confirm its effectiveness with a real body. The EMGs of the wearer with and without the suit are compared. The usefulness of the AB-Wear is confirmed by simulation and experiment.

    This article focuses on developing a pneumatic artificial muscle as a variable elastic device and a magnetorheological fluid brake as a variable viscosity device and a variable friction device. We executed a throwing motion using a 2-degree-of-freedom manipulator as a case study of the control of dynamic motion. To investigate the throwing motion, we proposed the spring model of the manipulator, which includes a variable viscoelastic joint. Next, the manipulator and the spring model were extended to 2 degrees of freedom. In addition, the spring model was verified by comparing the simulation and experimental results. The simulation results reproduced the experimental results. Furthermore, we maximized the velocity of the end effector during the throwing motion by searching for adequate drive timing of the second joint in the simulation. In the simulation, hand speed was improved by releasing the second joint on the basis of the angular acceleration of the first joint. Finally, the simulation results were reproduced experimentally under the same conditions.

    Recently, about 60% of worker suffers from low back pain in Japan. Hard working such as lifting and carrying provides a load to waist joint, and worker gets low back pain. So, we developed a power assist suit to reduce the load of waist joint. This assist suit has various futures; endoskeleton, high output and flexibility, because this device moves using two pneumatic actuators. This device generates active and passive assistive force. These forces can assist human motions according as situations. First of all, we analyzed the human motion by motion capturing software. The analysis results are substituted into human link model, and load of human body is estimated. Thus, we decided design and operation method of the assist suit using analysis results and a static assist suit model. The motion of wearer is &ldquo;lifting up motion&rdquo; and &ldquo;carrying motion&rdquo; in evaluation experiments, because these motions are frequently performed in manufacturing plant work. Each assistive force assists these motions, and effectiveness of assist suit was confirmed from decrease of electromyography (EMG) in wearing.

    Sub-seafloor exploration is important for biological and geological research. One of the major exploration tasks is the sampling of mud containing mineral resources and that of marine sediments. We designed a peristaltic-crawling sub-seafloor excavation robot comprising three units for propulsion, excavation, and extraction. The robot was designed to move freely under the seabed and was fitted with a flexible earth auger using universal joints, designed to operate in a bending state. We experimentally tested the performance of the earth auger and excavation unit under bending states with constant curvature. The ability of the auger to excavate and convey soils while in the bending state was confirmed.

    In recent years, powdered materials have been often used in various industries. Among the various uses of powders, we focused on the conveyance of the developer in the printers. Screw conveyors are commonly used in the printer for the conveyance of the developer. However, this presents the problems such as the condensation of the developer by the shearing force and the temperature rise. Thus, low shear and high-speed conveyance at a low temperature is required. In an alternative approach, we developed a transport device that mimics the intestinal tract and demonstrated successful transport of the highly viscous and solid-liquid mixed fluids. In this study, to overcome the above problems, we considered the peristaltic conveyor. We investigated the ability of this conveyor to convey powder by using the expansion of the rubber. In this work, we performed conveyance experiments by using the carrier used in the printer and measured the weight to determine the conveyance performance per unit of time. By measuring the changes in the conveyance amount due to the changes of the motion interval time, we determined the condition for obtaining the maximum conveyance amount. We then determined the conveyance amount per unit time for the developer.

    Copyright © 2016 by the International Astronautical Federation (IAF). All rights reserved. The target of this study is to realize the continuous solid propellant producing technique for a cost reduction of solid rocket motor systems. In the process of the solid propellant manufacture, the mixing process controls the quality of the loaded solid propellant; the batch process is impossible to be replaced at present. We have considered the peristaltic pumping action mixer as one of the candidates for the continuous mixer. This mixer system is based on the artificial muscle actuator (soft actuator), and it is elongated and contracted by the pressurized gas. The system has some segments that has double rubber pipes (inner/outer), and the units can work independently. The outer rubber tube controls the shape change direction; the inner one works as a mixing chamber. The outer tube is swollen by the pressurized gas and the segments constrict axially; the inner tube inflates and the free volume can be changed. We expected that this mixer system has possible to replace the batch process by the continuous one. The peristaltic motion enables not only the mixing but also conveying even high viscosity slurry. The mixing mechanism by the soft actuator compress has no impact for the safety of the solid propellant handling. In this research, the mixing completeness of the composite solid propellant slurry by the peristaltic pumping mixer was estimated. The dispersion of the particle materials in the binder and the existing voids was observed by the X ray CT microscope. The solid propellant samples were made by our mixing system. The test materials were as follows: Hydroxyl terminated polybutadiene (HTPB) polymer as for the binder, aluminum powder as for the metallic fuel, dioctyladipate as for the plasticizer, ammonium perchlorate particles as for the oxidizer. The propellant composition was HTPB/AP/Al = 14/68/18 in massThe result showed that the mixer we proposed could mix the propellant slurry. The X ray CT scanning images showed that the solid materials well dispersed through the analysis of the luminance histograms.

    It is difficult to research small diameter pipes using conventional devices. In order to solve this challenge, this paper focuses on the locomotion of an earthworm that is capable of moving stably in a narrow space. A peristaltic crawling robot was developed which was capable of traveling 100 m through a 100A specification pipe using a peristaltic movement. However, especially in long distance inspection, and in elbow pipe, friction force between cable and pipes are too larger to ignore. Therefore, the friction force makes the robot impossible to inspect for long distance. And the friction force injure the cable and air tube equipped in the robot. In this paper, we developed an attachment to reduce the friction force. Using this device, we conducted experiment to measure friction in elbow pipe, and confirmed its effectiveness.

The robot consists of a seven unit section, six joints, and a head unit equipped with a camera. It is actuated with the use of an artificial muscle operated by air pressure. The effectiveness of the new robot was evaluated by conducting experiments in horizontal, vertical, and bent pipes. In addition, the authors proposed and validated a new movement pattern to increase the robot speed in 90 degrees elbow pipes.

    Bipedal robots capable of various dynamic motions such as walking, running, and jumping have been developed in recent years. In particular, these dynamic motions require the use of high power in a short time when the robot kicks off the ground. Furthermore, it is necessary to decrease the impact force that a robot is subjected to when landing during these motions. Unfortunately, rigid actuators tend to become heavier as their output increases. Therefore, we focus on the method for obtaining a high output using elastic energy. However, the use of the elastic element only leads to robot vibration. Therefore, to control the dynamic motion, we adopted the viscosity element to the robot joint. In this study, we focused on a straight-fiber-type artificial muscle for the elastic element and a magneto rheological brake for the viscosity and friction elements, respectively. A previously designed monopedal robot was able to jump 82.5 mm using a sliding rail and counter weights; however, the robot shook upon landing because of the presence of the elastic element in its artificial muscles. In this paper, we first proposed a dynamic model of the previously developed monopedal robot. We then performed vertical jumping simulations of the robot to confirm the model's utility.

    In this study, a variable viscoelastic joint system with a clutch for a human assistance was proposed. The variable viscoelastic joint system comprised antagonized artificial muscles and magneto-rheological fluid brake (MR-brake). This system enabled the human assisting device such as exoskeletons to retain structural softness when compared with the existing devices driven by motor and reduction gear, which could only achieve superficial softness. In addition, a clutch system that provided high back-drivability to the wearer by structurally separating the device from the wearer was proposed. As an initial step in designing the human assisting device, a prototype with the proposed variable viscoelastic joint system for knee assistance is developed. Also, its control method were developed. Furthermore, experiments were conducted to confirm the influence of the proposed viscoelastic joint system on the wearer and the effectiveness of the clutch system.

    Lower back pain continues to be an issue worldwide. One cause of lower back pain is the burden on the lumbar region caused by the handling of heavy objects. To reduce this burden on the lumbar region in the lifting, the Ministry of Health, Labour and Welfare in Japan has recommended a lifting technique called "squat lifting." However this technique, which supports a large force on the knee, is not very popular. Therefore, to spread the use of squat lifting, we aimed to develop a power assist suit for knee auxiliary. In this study, firstly, the validity of the squat lifting in lower back pain was measured. Next, to construct a prototype based on the target value, the knee joint moments from motion analysis of squat lifting was estimated. Finally, the prototype was mounted on a human body to evaluate its performance. And we confirmed the effectiveness of the prototype.

    This paper focuses on control of variable viscoelasticity joint manipulator. Each joint consists of pneumatic rubber artificial muscle and magnetorheological fluid. And the joint can generate instantaneous force by accumulating potential energy in artificial muscle. Using instantaneous force appropriately, robots can perform dynamic motion such as jumping and throwing like a human. These motions are expected to contribute to the efficient transport of objects and improve the robot's mobility. And also, elasticity and viscosity of joints are needed to control appropriately to achieve target task. Therefore, we proposed a method to control variable viscoelasticity of joint. We set throwing motion as a target task. And elasticity and viscosity are decided by simulation. In addition, simulation result is optimized by Particle Swarm Optimization (PSO) algorithm. Finally, we conducted throwing experiment to reproduce the simulation result. As a result, simulation result showed that elasticity and viscosity changed to accelerate end effector. However, experimental result showed deviations from simulation result because of model error.

    Low back pain of workers is increased in workplaces that involve hard work. It is caused by excessive loading of the waist joint and muscle fatigue. Therefore, power-assist suits have been developed to decrease the load on the waist joint. However, previous power-assist suits have had problems such as low output or heaviness. Thus, we have developed an assist suit that is lightweight and exerts a large force. A balloon actuator and pneumatic artificial muscles are attached to assist suit as the actuators. The assist suit has various desirable features: lightweight, flexibility, and high output. First, human motion is analyzed for the development of the assist suit. The assist suit is developed to assist the waist joint torque. The assist suit is modeled, and the theoretical values of its generation force are estimated using an assist-suit model. Finally, the assist suit is evaluated by measuring the surface electromyography (EMG). The EMG of the wearer is compared with that without the suit. The effectiveness of the assist suit is confirmed by a decrease in EMG.

    At present, city infrastructures are supported by buried gas pipes. Recently, to prevent gas leakage from old gas pipes (which can lead to accidents), routine inspections are required. However, current inspection methods require enormous cost and time. To solve this problem, researchers have developed various pipe inspection robots; however, these robots have difficulty climbing or maneuvering through narrow pipes. Therefore, we focused on the peristaltic crawling of an earthworm. This motion provides a large contact surface area in small spaces, enabling movement through narrow pipes. Therefore we developed a peristaltic crawling robot. It is installed with a straight-fiber-type artificial muscle and is driven by a fire-safe pneumatic system. However, delaying air transmission reduces the velocity of the robot. Considering the costs of hiring workers and the problems created by incidents such as roadblocks, a short inspection time is desired. Installing a solenoid to increase the robot's velocity is impractical in gas pipes because it increases the fire risk. Therefore, we propose an air discharge hole on-off mechanism and instant-supply high pressure and confirm their efficacy in the present study.

    Recently, force feedback devices that intuitively achieve excellent operation have attracted attention in a wide range of fields such as remote operation, virtual reality, and medical training systems. However, it is difficult for conventional devices to widely display soft and hard objects because of driving motors. Moreover, they are likely to be hazardous in the event of delayed response to an unexpected external force. To solve these problems, we previously developed a force feedback device using pneumatic artificial muscles, which are structurally flexible and have wide a range of stiffness, and magneto rheological clutches. Furthermore, we confirmed that any three-dimensional virtual object can be displayed using the developed device. However, when the operation part of the force feedback device is moved away from the virtual object, it remains stuck to the virtual object. In this study, we propose a system to reduce the sticking phenomenon and experimentally confirm the reduction rate (85%). Moreover, we displayed viscous torque as a new application of the feedback device.

    We have been developing an excavation robot for lunar subsurface investigations. The robot locomotion is based on the peristaltic crawling of an earthworm, which enables stable movement. The robot comprises three units: propulsion, excavation, and discharging units. In our previous research, we demonstrated that the propulsion and excavation units can excavate down to 650 mm without the discharging unit. However, when all three units were incorporated into the robot, excavation was limited by soil dropping from the discharging unit. To overcome this problem, we developed a novel soil circulating system. This paper presents the new system and experimentally verifies its feasibility. Finally, the contribution of the proposed system is confirmed in an excavation experiment. The robot's performance was remarkably improved by the system, and its excavation depth increased to 938 mm.

    Lower back pain accounts for more than half of all reported on-the-job ailments, escalating from a personal challenge to a broader societal challenge. Researchers have developed a power assist suit intended prototype to reduce the incidence of lower back pain in the workplace when process automation is not possible. Equipped with two pneumatic actuators, the prototype suit is lightweight, flexible, and efficient. The prototype suit can assist human motion using passive and active forces. In this study, researchers confirmed the effectiveness of passive assistive force. Two types of motion were considered: lifting and unloading in a crouching position and carrying. Researchers first analyzed the subject motions using video analysis software. Waist joint loads were estimated using motion analysis results and a human link model. Second, researchers determined the power assist suit's operational parameters and developed a power assist suit model. Lastly, researchers confirmed the passive force prototype suit's effectiveness based on measured changes in generated force and electromyography.

    The performance of a robot can be enhanced by increasing its output. However, increasing the output of rigid actuators such as motors and hydraulic actuators will likely increase the weight of the robot. Conversely, organisms such as human beings achieve high output within a short time by accumulating and releasing the elastic energy stored in their muscles; thus, providing an instantaneous force. Moreover, the viscoelastic properties of muscle enable organisms to control their instantaneous force outputs and overall movements. Therefore, in this study, we developed a manipulator with two-degree-of-freedom (DOF) variable viscoelastic joints. The manipulator comprised straight-fiber-type artificial muscles and a magnetorheological (MR) brakes. The ability of a manipulator to generate controlled movement from an instantaneous force was tested in a throwing operation. This simple two-DOF variable viscoelastic manipulator with apparent viscosity control by the MR brakes achieved successful throwing motions. However, it was not possible to calculate the experimental parameters from the target operation in previous study. Therefore, we focused on particle swarm optimization (PSO) as a parameter search method. In this paper, we try to optimize parameters of the throwing movement by combining the spring model of a two-DOF variable viscoelastic manipulator with the PSO method.

    Unmanned rescue, observation and/or research vehicles with high terrain adaptability, high speed, and high reliability are needed to reach difficult locations. However, most vehicles achieve improved performance over rough terrain at the expense of low speed and/or complex mechanisms. We developed a blade-type crawler robot with a very simple and reliable mechanism, capable of traversing uneven terrain at high speed, using aerodynamic devices. As these small devices are in the low Reynolds number region, we tested a wing that made use of the ground effect. We experimentally confirmed the success of this approach in improving the traveling speed and ability to traverse uneven terrain. The robot with aerodynamic lift was climbed 1.5 times higher obstacle than without wings.

In contrast, a wearable force feedback device allows us to interact with virtual objects while moving in virtual space. In this study, we have developed a 1-DOF wearable force feedback device with MR brake and pneumatic artificial muscles. These actuators are lightweight, have a high power density, and are controlled by feed-forward control. This device is equipped with the operator's arm and renders various forces, such as friction, elasticity, and viscosity. In this paper, we improve the device to solve existing problems from previous studies. The proposed device is tested to confirm its basic properties. It is applied to augmented reality space and comparisons of subjective evaluations between virtual objects and actual objects

    We have developed an earthworm-type 25A pipe inspection robot using a pneumatic drive. However, the developed robot had a low locomotion speed. This was due to the fact that the contraction amount of the pneumatic artificial muscle used for driving the actuator of the robot was small. To resolve the problem and increase the amount of movement of the robot, an extension actuator to extend in the axial direction was developed. The developed actuators was tested in an experiment that measured the extension amount. At that time, it was confirmed that the actuator largely extended while bending. Therefore, an experiment was performed to verify the bending of actuators and to confirm the extent of the bending. Test results confirmed that the movement tracing of extension actuator with tension springs on both the inside and outside (actuator2) was straighter than that of extension actuator that used the tension spring only on the inside (actuator1). In addition, the developed actuator was tested in an experiment that measured pushing force and pulling force. It was also verified that the extension actuator satisfied the force requirements for the robot.

    Sub-seafloor explorations are important for biological and geological research. Sampling mud is one of the major sub-seafloor exploration procedures. The mud-including mineral resources and marine sediments are potentially valuable resources for future studies. Therefore, we propose a peristaltic-crawling-based sub-seafloor excavation robot for deep sea exploration. This robot consists of three units (propulsion, excavation and extraction units), enabling it to move freely through mud. The excavation and propulsion units are fitted with an earth auger and artificial muscles, respectively. In this paper, we verify the propulsion actuator as the first stage of robot development. First, we evaluate the performance of an oil hydraulic artificial muscle under water pressure. Next, we develop an excavation robot by incorporating a pneumatic artificial muscle into a robot and then experimentally evaluate propulsion and excavation of the robot. We confirmed that the artificial muscle appropriately performs as an actuator for the excavation robot.

    In recent years, the demand for rocket launching has increased due to the development of space technology. However, using inexpensive rockets is not always possible. Although the cost of solid-propellant rockets is relatively reasonable, safely manufacturing a large amount of solid propellant is difficult, and the manufacturing process is disjointed. Therefore, safe and continues manufacturing of solid propellant is necessary. On the basis of the movements of the intestinal tract, we realized that the movements required for transport and mixing of solid propellants are possible to achieve without the application of a large force. By mimicking these intestinal movements, we can safely and continuously manufacture a large amount of solid propellant. We developed a peristaltic pump, based on bowel peristalsis, using straight-fiber-type artificial muscle, and in this study, we demonstrate the usefulness of this pump for transporting the highly viscous fluids and solid-liquid mixed fluid. We consider that the peristaltic pump can also be effectively used as a mixing device. In this paper, we show that mixing one highly viscous fluid with another is possible by measuring the luminance values. In the manufacturing process, we use glass beads with the same diameter as microparticles and a sodium polyacrylate aqueous solution resembling a high viscosity fluid or hydroxyl-terminated polybutadiene as the raw material in the solid propellant. We then measure the glass beads in the resulting solid-liquid mixed fluid.

    A wearable force feedback device enables us to dynamically interact with a virtual object while moving in a wide virtual space. We have developed a wearable force feedback device with a pneumatic artificial muscle and a magnetorheological (MR) brake. These mechanical elements show quick response by feed-forward control and have high power density. In this paper, we tackled on weight saving of the device, and measured basic property again. Afterward, we evaluated whether operators could perceive the difference when rendered different magnitudes of frictional force or elastic force. The operators were rendered one of the five levels of force, and replied which level this force was.

    Desktop haptic device has been developed in the field of rehabilitation and entertainment. However, the desktop type restrains human's movement. Therefore, it is difficult to receive force sense information, moving to wide range position and posture. In this study, we developed a 1-DOF wearable haptic device with pneumatic artificial muscles and a MR brake. These smart actuators have high power density and change its output force structurally. Therefore, this haptic device can render various force sense such as elasticity, friction and viscosity. In this abstract, we describe two experiments rendering elasticity and friction to evaluate the performance of the device.

    This paper describes the development of an in-pipe inspection robot for use in half-inch pipes. Half-inch pipes are commonly used in factories and residences, and in-pipe inspection is essential for preventing accidents caused by burst pipes or corrosion. In-pipe inspection is currently endoscopically conducted; however, endoscopes cannot be inserted into pipes that are more than 15m long or that have complex shapes, such as elbows. Therefore, various in-pipe inspection robots have been developed, though very few can travel inside half-inch pipes, and none can pass through a 90° elbow. Moreover, no study reports in-pipe robots making long-distance runs within half-inch pipes. The authors have developed a peristaltic crawling inspection robot with pneumatic artificial muscles for use in half-inch pipes; they seek to enable the robot to pass through a 90° elbow and have studied the robot's ability to travel long distances of more than 15m.

    This study aims to develop a new type of peristaltic pump that transports high-viscosity and solid-liquid mixture fluids. Pumps capable of transporting such fluids are essential in various situations such as factory transportation, outdoors, and emergencies. These fluids are conventionally transported by positive-displacement and rotodynamic pumps. However, solid-liquid fluids could collide with the impeller of the rotodynamic pump and thereby damage the pump, whereas the positive-displacement pump must be sufficiently large to apply high pressure to the transported fluid. A small pump that can transport these fluids would save factory space and enable outdoor applications such as dredging operations. Thus, we adopted earthworm peristalsis as a model mechanism of fluid transport within a standard plumbing infrastructure. The insertion-type peristaltic pump developed in this study uses an artificial rubber muscle to achieve an earthworm-like mechanism. The capability and energy efficiency of the mechanism is evaluated in water transportation experiments.

    Recently, planetary investigations have accumulated basic data through various aerospace explorations. However, the investigations of underground such as moonquakes, heat, and conditions of the soil have not revealed much. Therefore, the authors have developed a novel, small planetary subsurface excavation robot that uses the peristaltic crawling of an earthworm as its underground propulsion method. In this study, the authors focused on two types of geotechnical tests: pressure meter and shearing tests using the excavation robot. These tests were conducted by measuring displacement and force in the radial and vertical directions inside the soil, using the excavation robot's own hardware system. This paper describes these geotechnical tests, which used the propulsion unit of the robot and measured the soil parameters, e.g., internal friction angle, adhesibility, and elastic constant. From the experiments, the authors evaluated and discussed results by comparing with reference data. The authors confirmed that the propulsion unit could measure the soil parameters and propel itself underground at the same time.

    Humans perform various motion such as jumping or throwing without high vibration, via variable viscoelasticity characteristics. On the other hand, highly rigid actuators such as geared motors or hydraulic actuators are widely used in industrial robots. It is difficult that they have variable viscoelasticity for them. In addition, to obtain high-speed motion, it is necessary to increase the actuator output as the robot weight increases. We have developed a one-degree-of-freedom manipulator with a variable rheological joint using a straight-fiber-type artificial muscle and a magnetorheological (MR) brake. With the generation of instantaneous force, the dead and rise times decreased compared to the conventional method. After the generation of an arbitrary instantaneous force, we controlled the robot's arm position by applying an equilibrium force on the joint. Furthermore, we controlled the vibrations of the arm by controlling the MR brake using an evaluation function. By this impedance control, response of the arm was improved without large loss of power.

    This paper describes a development of an colonoscopic device that veering-out a latex tube with jamming by granular materials and an application to a large intestine of dead swine. Recently, colorectal cancer is increasing. However, the cancer can be cured completely if it is discovered and treated early with a large intestine endoscope. A conventional endoscope can screen and heal the inside of the intestine, but such surgery is difficult for doctors. In this study, in order an attempt to solve these problems, we propose an endoscopic device that veering-out a latex tube with jamming by granular materials. This device can pass through the sigmoid colon of dead swine that is set like a human without difficult operation. Unlike other endoscopic robots, our device can support the endoscope. Thus we can easily perform various functions of the conventional endoscope. Here we explain our device using rice as jamming material. Next, we describe our experiment confirming the efficacy in large intestine model. We also confirm the availability of the endoscopic support device for use in the large intestine of a dead swine.

    We have developed the traveling wave type omni-directional mobile robot that imitates the snail locomotion mechanism. An advantage of this movement mechanism is that it enables stable motion because of a large contact area. We think that this stable motion is applicable to wall climbing. In this paper, we developed magnetic adhesion mechanism that can be switched adhesion and installed it in the robot. Furthermore, we confirmed the performance of this robot through experiments.

    This paper describes a proposal for a locomotion strategy for an omnidirectional wall-climbing robot for spherical surfaces. This robot was developed for inspecting the walls of ships and gas tanks, which require regular inspection. Because such walls are ferromagnetic, many other wall-climbing robots have been developed. However, the stable movement of such robots is prevented by their small contact area. Conversely, we have developed a travelling-wave-type omnidirectional mobile robot that uses the locomotion mechanism of a snail. This robot travels omnidirectionally and achieves stable movement through its large contact area. Previously, we equipped our traveling-wave-type omnidirectional robot with a permanent magnetic adhesion mechanism and confirmed its wall-climbing ability. Moreover, we installed universal joints to allow this robot to adjust to curved surfaces. In this paper, we model the robot in 3-dimensional space and suggest an omnidirectional locomotion method for spherical surfaces. Through simulation, we verify the availability of locomotion strategy.

    We developed an earthworm-type 15A pipe inspection robot with pneumatic artificial muscles (PAMs). The movement of the robot is performed by a drive unit that repeatedly expands and contracts the muscle. Pressurized air is supplied to the muscle via an air tube. The robot is required to change the specifications of the tube in accordance with the distance of inspection. When the specifications change, the responses of air transmission and the drive unit also change. To date, the optimum operating condition of the drive unit has been obtained experimentally, but this is an extremely time-consuming problem. Thus, we derive a dynamic characteristic model of the PAMs that considers the length of the air tube. Then, the usefulness of the model is confirmed by comparing its results to experimental values of the artificial muscle.

    Purpose - This paper aims to develop a wave-transmitting mechanism for a travelling-wave-type omnidirectional mobile robot. Existing omnidirectional mechanisms are prone to movement instability because they establish a small contact area with the ground. The authors have developed a novel omnidirectional mobile robot that achieves stable movement by a large ground-contact area. The proposed robot moves by a wave-transmitting mechanism designed for this purpose.
    Design/methodology/approach - To achieve stable movement, a spiral-type travelling-wave-propagation mechanism that mimics the locomotion mechanism of a snail was developed. The mechanism was applied to an omnidirectional mobile robot.
    Findings - The practicality of magnetic attraction was verified in experiments of the wave-transmitting mechanism. Moreover, omnidirectional movement was confirmed in a robot prototype adopting this mechanism.
    Research limitations/implications - The proposed robot will eventually be deployed in human spaces such as factories and hospitals. A mechanically improved version of the robot will be evaluated in load-driving experiments and equipped with control systems.
    Originality/value - This paper proposes an omnidirectional mobile robot with a large ground contact area that moves by continuous travelling waves. The practicability of this mechanism was experimentally confirmed, and a prototype robot achieved omnidirectional movement.

    The performance of a robot can be enhanced by increasing its output. However, increasing the output of rigid actuators such as motors and hydraulic actuators will likely increase the weight of the robot. Conversely, organisms such as human beings achieve high output within a short time by accumulating and releasing the elastic energy stored in their muscles (thus providing an instantaneous force). Moreover, the viscoelastic properties of muscle enable organisms to control their instantaneous force outputs and their overall movements. Therefore, in this study, we developed a manipulator with a 2-degree-of-freedom (DOF) variable viscoelastic joint. The manipulator comprises a straight-fiber-type artificial muscle and a magnetorheological (MR) brake. The ability of the manipulator to generate controlled movement from an instantaneous force was tested in a throwing operation. This simple 2-DOF variable viscoelastic manipulator with apparent viscosity control by the MR brakes achieved successful throwing motions.

    Lifting heavy objects increases the risk of low back pain. In this study, we calculate the load exerted on the human body during an actual lifting operation. To assist lifting, we propose an endoskeleton-like suit that exerts an assistive force. A prototype of the assist suit is developed in this study. The force is exerted by a straight-fiber-type artificial muscle combined with an amplification mechanism. The notion of assistive force was subjectively evaluated by wearers, and confirmed in on a visual analogue scale. The electromyography signals of wearers were decreased, confirming the subjective assist effect.

    Force feedback devices have been recently adopted in virtual reality, rehabilitation, and medical training systems. Many of these devices convey the human forces sensed by the impedance control using motors; however, motorized actuators are disadvantaged by low output and backdrivability. To resolve these disadvantages, we developed a delta-type parallel-link robot using pneumatic artificial muscles and magnetorheological (MR) clutches. The artificial muscles deliver high output and backdrivability, while the MR clutches enable fast responses. Moreover, because the stiffness of its pneumatic artificial muscles directly responds to forces, our robot detects human forces without feedback from force sensors. This study introduces the prototype of our delta-type parallel-link robot, and evaluates its performance in elastic movement experiment. Finally, we confirmed that our prototype robot can obtain the stiffness and unloaded condition through its MR clutches without feedback from force sensors.

    Bipedal robots capable of various dynamic motions such as walking, running, and jumping have been developed in recent years. In particular, these dynamic motions require high power for short durations of time when the robot kicks off the ground. Furthermore, it is necessary to reduce the impact force that a robot is subjected to when landing during these motions. When humans perform similar motions, they generate an instantaneous high-power force using an elastic element and dampen the impact force using a viscous element in their muscles. Therefore, a robotic leg designed for jumping that relies on these elements has been developed. It uses a straight fiber-type artificial muscle and a magnetorheological (MR) brake. A previously designed one-legged robot was able to jump 82.5 mm using a sliding rail and counter weights; however, it shook upon landing due to an elastic element in its artificial muscles. Here, therefore, an MR brake to dissipate energy is applied to the robotic leg in order to suppress vibration. Landing experiments performed with the newly designed one-legged robot confirm that the proposed method (i.e., using the MR brake) is able to suppress vibrations.

    In recent years, observations and explorations of the deep seafloor have been actively pursued. One goal of such explorations is to obtain the samples of seafloor mud and its inclusions. Mud that contains minerals and submarine microorganisms has great potential for studies in biology, geology, and marine science. To contribute to these efforts, we propose a robot using peristaltic crawling to excavate deep seafloor. The robot consists of three parts: excavation, propulsion, and extraction units. The propulsion actuator of the proposed robot must be able to function under water at high pressures. As the first stage in the development, we developed a subunit using an oil hydraulic artificial muscle intended for use in deep sea, and conducted a performance experiment under water pressure. Our results confirmed that the artificial muscle can be used in water pressures of up to 5 MPa.

    Recently, the use of haptic technology has been expected in various fields, such as medicine and entertainment. In general, haptic devices are actuated by DC motors. However, DC motors have active rendering and can cause serious accidents when the system runs out of control. On the other hand, systems that employ a brake are stable and intrinsically safe. However, such systems have several haptic rendering limitations. Therefore, we have developed a semi-active-type haptic device using variable viscoelastic elements: an electrorheological (ER) devices and pneumatic artificial muscles. In this paper, we proposed control modes according to the haptic application, and we demonstrate several haptic experiments. Finally, we confirm that the novel semi-active system achieves haptic rendering of friction, viscous friction, virtual wall, and stiffness.

    We have developed a robot that can inspect long distances in thin sewer pipes. Inspections of sewer pipes are necessary to prevent accidents such as road caving accidents. However, thin sewer pipes cannot be easily inspected by existing methods. To solve this problem, we developed a peristaltic crawling robot that mimics earthworm locomotion. This robot comprises six units: five joint parts and a head part with a camera that inspects inside the sewer pipes. As the actuator in the unit is a pneumatic artificial muscle, the robot is driven by air pressure. Air is supplied to each unit through an electric valve mounted directly on the unit, thereby preventing delay in air transfer. We confirmed that the robot can stably drive through horizontal and vertical sewer pipes. In driving tests through a bending pipe, we identified materials for the joint parts that enable the robot to smoothly travel through the pipe. During these tests, we further evaluated the robot's traveling performance by measuring its driving speed through the pipe. © 2014 IEEE.

In previous studies, the authors showed that this pump can transport water through a vertical pipe and a bent pipe. However, the performance of this devise has not been compared with that of conventional pumps. Thus, this paper evaluates the efficiency of the insertion-type peristalsis pump and has demonstrated that the insertion-type peristalsis pump has excellent energy efficiency.

    Recently, many omnidirectional mobile robots have been developed, which require omnidirectional mobile mechanisms to allow them to move within narrow, complicated passages. However, existing omnidirectional mobile mechanisms cannot achieve stable movement because of their small contact areas. In this paper, we propose an omnidirectional mobile robot that achieves stable movement through a spiral-type traveling-wave-propagation mechanism based on a snail's locomotion mechanism. To demonstrate the robot's performance, we conducted a driving experiment using a prototype.

    Recently, research of a haptic device that renders human arbitrary-force sense has been accelerating for application in rehabilitation and virtual reality/augmented reality devices. Generally, these devices are actuated by electric motors
    however, the actuators have low stiffness output and low backdrivability. In an effort to counteract these drawbacks, we developed a delta robot actuated by straight-fiber-type pneumatic artificial muscles. This robot renders human arbitrary-force sense without force sensor feedback. Furthermore, this robot has backdrivability derived from the softness of the pneumatic artificial muscles and no backlash because the structure does not use gears. Thus, by adopting a delta mechanism as a haptic device, high stiffness output and low inertia force are realized. In this study, we introduce the development of the delta robot as the prototype of a haptic device and conduct position-control and stiffness-control experiments to examine the device's fundamental properties. From the experimental results, we confirm that end position is controllable by both sides of static and dynamic state, and the stiffness of the end plate is controllable without feedback of the force sensor. © 2014 IEEE.

    This paper describes the development of an omnidirectional wall climbing robot with permanent magnets for inspecting the walls of ships and gas tanks. These features require regular inspection, which is costly and exposes workers to risk. Because such walls are ferromagnetic, they can be monitored by robots with permanent magnets, and many wall-climbing robots have been developed. However, stable movement of such robots is prevented by their small contact area. Previously, we have developed a traveling wave type omnidirectional mobile robot that uses the locomotion mechanism of a snail. This robot travels omnidirectionally and achieves stable movement through its large contact area. We expect that this locomotion mechanism is suitable for wall climbing. In this paper, we have equipped our traveling wave type omnidirectional robot with a permanent magnetic adhesion mechanism, enabling it to climb walls. In locomotion experiments, we confirm that the robot can move omnidirectionally on a horizontal surface (0 degrees), a wall (90 degrees), and a ceiling (180 degrees).

    As the aged population increases, increasing numbers of people require walking support as the strength of their leg muscles deteriorates. We have developed a flexible power walking assistant system based on pneumatic artificial muscle. To date, the walking assistance effect of this approach has been validated in experiments, but few subjects were recruited. In the present study, we have incorporated pneumatic rubber artificial muscle into a new mechanism, enabling smaller and lighter weight devices for walking assistance. Unlike conventional mechanisms of this type, which require separate artificial muscles for each foot, our proposed mechanism assists both feet by a single artificial muscle. A prototype model of our proposed new mechanism was applied to artificial muscles, and its practicality was evaluated in operational experiments. © 2014 IEEE.

    Exploration below the lunar surface has great potential for scientific progress and the future of space explanation. However, as of now, little is known about the environment of the lunar subsurface, but the international space community has plans to explore it. The development of an excavator that can perform underground investigations has been needed, so we have developed one with a peristaltic crawling mechanism. The robot consists of propulsion and excavation units. The propulsion unit consists of three propulsion subunits which together form the peristaltic crawling mechanism. The excavation unit has an earth auger to dig up and transport soil. In this study, we propose a new type of propulsion subunit. It has a belt drive system to facilitate the smooth movement of the propulsion subunits, and it enables the robot to support three subunits. We also perform experiments in which the excavation robot burrows into red soil to depths of up to 600 mm.

    We have developed a novel planetary subsurface explorer that is capable of excavating lunar soil and carrying out scientific investigations. Our developed device consists of two units: a propulsion unit and an excavation unit. The propulsion unit that is based on the peristaltic crawling of earthworm maintains the body position and orientation of the robot and also reduces friction, which is the factor that traditionally prevents robots from excavating to significant depths. The excavation unit excavates and clears a space for the robot to tunnel into densely packed soil. In this paper, we discuss strategies for underground excavation. Next, we develop the excavation and propulsion units, and conduct several experiments to test these units. Finally, we develop a prototype subsurface robot with both units integrated in one package. The prototype exhibits good excavation performance in terms of depth reached-430 mm-both under its own full weight and for 1/6 of its own weight. In other words, the prototype shows excellent robustness to the gravity differences on the Earth and the Moon. With appropriate dust removal, operation has been demonstrated to a depth of 650 mm without any slowing down. The same performance is considered possible for much greater depths.

    Mixing tank is a device which is used in a variety of chemicals to stir. When using this apparatus, the controlling temperature in the tank is important. So flow a heat medium or a refrigerant to the internal of the jacket to control it. Although a large amount of deposits are formed in the inner wall of jacket, there is no way to clean up or to inspect inside of the jacket because it's too narrow space and entrance. Therefore, we developed peristaltic crawling robot for vertical narrow space, and realized the locomotion in 50[mm] wide space. In addition to that, we simulate in this robot and do experiment to compare the results of simulation. Also, to achieve driving on curved narrow space in mock-up of the mixing tank.

One is an excavation robot for cleaning the inside of the jacket, and the other is a polishing robot for inspecting the walls. The excavation robot consists of four units and three joints. This robot mimics the peristaltic crawling motion of an earthworm. On the other hand, the polishing robot consists of five units, a metal brush and two wing parts. This robot polishes the walls inside the jacket. Two types of experiments were performed with the two robots. One of the experiments was a driving test inside the jacket. The other was to eliminate sediment on the local walls.

    Recently, there have been many studies for developing robots that perform tasks instead of humans. In this study, we focus on tasks to be performed at high places above the ground, which can be dangerous and costly. Therefore, a robot having the ability to climb a wall is preferred for an automatic maintenance system, instead of humans. This paper reports the development of a wall climbing robot, for which two new mechanisms have been adopted: a mobile mechanism using traveling wave propagation and an adhesion mechanism using a centrifugal fan. This mobile mechanism modeled the locomotion mechanism of a snail. This mobile mechanism has a large contact area and is extremely stable. Therefore, it can move stably on both smooth and rough surfaces. In this study, we developed a mobile mechanism that uses a traveling wave propagation system. In addition, we developed a wall climbing robot using this mobile mechanism, and conducted climbing experiments on various walls. We confirmed that this robot can climb the walls in the tests.

    Recently, the development of mobile robots is actively pursued. These robots are expected to have high mobility, allowing them to work in various scenarios such as rescue and exploration. Therefore, we focused on the hexapod robot for stable operation in an irregular terrain. We developed a leg using the parallel linkage mechanism and pneumatic rubber artificial muscles, and constructed a model of the legs. The model reproduced the experimental result. Then, we developed a hexapod robot which can support its weight mechanically using these legs, even without a power supply. Also, we demonstrated that our robot could walk. Furthermore, we confirmed experimentally that the robot supported loads that were about 4 times its weight.

    This paper describes the development of an endoscopic device that veers out a latex tube with jamming by granular materials. Colorectal cancer can be cured completely if it is discovered and treated early with a large intestine endoscope. A conventional endoscope can screen and heal the inside of the intestine, but such surgery is difficult for doctors, and it can take 300 or more training sessions to learn the technique. Even experienced doctors can occasionally spend an hour to perform this operation. In this study, in order an attempt to solve these problems, we propose an endoscopic device that veers out a latex tube with jamming by granular materials. This device can pass through the sigmoid colon without pulling it up, and because of the jamming transition by granular materials, this robot can also become rigid and take on the shape of the sigmoid colon. Unlike other endoscopic robots, our device can support the endoscope. Thus we can easily perform various functions of the conventional endoscope. Here we describe our approach for insertion of an endoscope. Next, we describe our experiment confirming the efficacy of the jamming transition. We also confirm the availability of a prototype of endoscopic device to veer out a latex tube with jamming by rice granular using a large intestine model has a about 90-degree angle.

    In recent years, there is an increase in the number of people that require support during walking as a result of a decrease in the leg muscle strength accompanying aging. An important index for evaluating walking ability is step length. A key cause for a decrease in step length is the loss of muscle strength in the legs. Many researchers have designed and developed orthoses for walking assistance. In this study, we advanced the design of an orthosis for walking assistance that assists the forward swing of the leg to increase step length. We employed a pneumatic artificial muscle as the actuator so that flexible assistance with low rigidity can be achieved. To evaluate the performance of the system, we measured the effect of assistance quantitatively. In this study, we constructed a prototype of the orthosis and measure EMG and step length on fitting it to a healthy subject so as to determine the effect of assistance, noting the increase in the obtained step length. Although there was an increase in EMG stemming from the need to maintain body balance during the stance phase, we observed that the EMG of the sartorius muscle, which helps swing the leg forward, decreased, and the strength of the semitendinosus muscle, which restrains the leg against over-assistance, did not increase but decreased. Our experiments showed that the assistance force provided by the developed orthosis is not adequate for the intended task, and the development of a mechanism that provides appropriate assistance is required in the future. © 2013 IEEE.

    Pumps capable of transporting high-viscosity fluids and solid- liquid mixtures are required during disasters such as floods and liquefactions, and in various industrial settings including sewage treatment and food processing plants. Moreover, it should be easy possible to install such pump systems. Today, turbine-, piston-, and squeeze-type pumps are often used to transport high-viscosity fluids and solid- liquid mixtures. However, these pump types have disadvantages. Turbine-type pumps cannot exert a high discharge pressure and stones often cause some damage to turbines. Piston-type pumps are usually quite large, because a high pressure is needed to transport large quantities of fluid, and squeeze-type pumps are large and complex. Furthermore, it may be difficult to arrange the bent pipes required by these systems because of the high friction between the fluid and pipe walls. Hence, an innovative transport system is desirable. © 2013 IEEE.

    Recently, a robot's activity has been spreading into the care setting and homes. For these robots to work alongside humans requires them to have the same flexibility as that of the human muscle and ensure safety even if they collide with humans. To satisfy these requirements, we examined pneumatic artificial muscles - which are not only provide high output but are also light, flexible, and safe - as robot actuators. However, the commonly used McKibben-type artificial muscles have several drawbacks. Therefore, we developed straight-fiber-type artificial muscles, which have a contraction ratio and force that surpasses those of McKibben-type artificial muscles. We also developed a 6-DOF manipulator that is actuated by straight-fiber-type artificial muscles. However, since the DOF of this manipulator is less than that of the human arm, it is difficult for the end effector to make detailed movements. To solve this problem, we developed a 7-DOF manipulator, introducing a new mechanism in the joints. In this paper, we introduce a new restraint condition to the inverse kinematic computation of this manipulator and propose the method of redundancy use. Finally, we conduct an experiment following the trajectory and verify the effectiveness of the proposed method. © 2013 IEEE.

    We have developed a robot to inspect narrow sewer pipes. Periodic inspections of sewer pipes are necessary to prevent accidents such as road cave-ins. However, the means to inspect narrow sewer pipe are limited. For example, conventional endoscopes are difficult and sometimes impossible to pass through a complex network of pipes. To address this issue, we developed a peristaltic crawling robot that imitates the locomotion of an earthworm. The actuator of the robot is composed of bellows-type artificial rubber muscles contracting and extending using air pressure. We confirmed that the robot can pass through straight, bent, successively bent, and more complex shaped pipes. The robot can also move in a vertical pipe, a pipe in water, and through pipes coated with lubricant. Finally, we evaluated the robot's traveling performance by measuring its speed.

    Subsurface exploration is required to obtain resources such as oil and minerals, and to construct buildings and houses. It would also be necessary in any future expansion of human activity on the Moon or other planets. We have developed a small unmanned planetary subsurface explorer suitable for nascent stages of exploration. The subsurface excavator consists of both propulsion and excavation units, and its movements are based on those of an actual earthworm. The prototype excavator showed good performance in excavation experiments, and it could excavate at the same depth as in its own weight in the case of an excavator that is 1/6th of its own weight using counterweights. It was difficult to obtain and evaluate an underground environment and the right condition for an excavator in the excavation process. Therefore, we improved a propulsion unit equipped with sensors to detect the pushing force in a radial direction and then performed excavation experiments using the improved excavator from a launcher. We discuss data obtained from sensors, the excavation depth and motor torque. Our excavator showed good performance.

    The demand for robots engaged in human activities, such as nursing care and housework, is presently growing. In the vicinity of humans, these robots must operate taking into consideration the human safety. Therefore, the actuator in these robots needs to be soft, light, and powerful. To fulfill these demands, we adopted artificial muscles as actuators of the manipulator. However, the McKibben-type artificial muscle commonly used for this purpose is problematic; therefore, we developed a straight-fiber-type artificial muscle that surpasses the output of the McKibben-type. We also developed two types of wrist joint manipulator for the 7-degree-of-freedom (7-DOF) manipulator. In this paper, we compare and evaluate the performance of the two types of wrist joints. Moreover, we propose a control system for this manipulator regarding the joint angle and stiffness. We used the PI control method to control the joint angle, and the torque feedback control method to control the joint stiffness. Finally, we performed experiments to verify the control system.

    In recent years, robots have penetrated the fields of nursing and housework. These robots are expected to work alongside humans and, therefore, must be secure, safe, and able to collaborate. Thus, robots actuators should be light, soft, and have operating characteristics similar to those of humans. In this regard, pneumatic rubber artificial muscles are of interest as actuators for these robots. However, the McKibben artificial muscle commonly used for this purpose have certain drawbacks. Instead, we developed a straight-fiber-type artificial muscle that surpasses the output and contraction ratio of the McKibben muscle. We also developed a seven degree of freedom manipulator actuated by straight-fiber-type artificial muscles. The main features of this manipulator are the differential gear mechanisms in the shoulder and elbow joints, and the pulley-in-pulley mechanism in the wrist joint. However, to make use these mechanisms, we had to address the issues present in existing manipulators. In addition, we carried out various calculations necessary to design a control system for this manipulator. We performed experiments to verify the performance of the manipulator and control system. We realized steady state position control of the manipulator. However, in the dynamic state, we observed an overshoot in the rise time of the step response and proposed a solution for this issue.

    This paper describes the development of an inspection robot for use in 1-inch gas pipes.
    These pipes are commonly used in residences and between gas meters and a main pipe that is buried under the road, and they require regular inspection. However, appropriately advanced inspection technologies have not yet been developed. An endoscope, which is the current inspection method, can only be utilized in a limited inspection scenarios. As for robot inspection, current in-pipe robots cannot pass through a 90-degree elbow, which has a radius of curvature equal to its inside diameter (R-c = 1.0 ID). However these elbows are frequently encountered in real-life environments.
    In this study, to solve these problems, we developed a peristaltic crawling robot with pneumatic artificial muscles for use in 1-inch gas pipes. This robot can pass through a 90-degree elbow (R-c = 1.0 ID) in the horizontal and vertical planes. In addition, this robot can be equipped with an endo scope and take videos inside a pipe. However, has been unable to pass through continuous elbows, which are occasionally encountered. For use in real-life environments, a robot is needed that can pass through continuous elbows.
    In this paper, we report the development of a robot that can pass through continuous elbows.

    We have previously developed a peristaltic pump based on the bowel mechanism by using an artificial rubber muscle that can transport fluids such as sludge without centralizing pressure. Unfortunately, it is difficult to attach the pump to various structures or manipulate the geometry for easy access. Herein, we focus on earthworm peristalsis as a model mechanism that can induce peristaltic activity in the pipe and transport fluids containing little water.
    We have developed a flexible device which can transport high-viscosity fluids and solid-liquid mixtures by applying the peristalsis mechanism of earthworms. In this study we investigate water transport using this insertion-type peristalsis pump in both straight and bent device orientations.

    Highly rigid actuators such as a geared motor or hydraulic actuator are widely used in industrial robots. To obtain high-speed motion, actuators need to increase the actuator output. However, to increase high-rigidity actuators output, it is necessary to make actuators larger. In contrast, humans perform motions with instantaneous force such as jumping or throwing by using muscles. These instantaneous forces are realized by accumulating potential energy to the muscles and the muscles releasing the energy in a short time. Therefore, in this study a 1-DOF manipulator with variable rheological joint for instantaneous force using an artificial muscle and a magnetorheological (MR) brake was developed. In this paper, the method of generating instantaneous force for this manipulator was proposed. Further, the experiment of the proposed method was also conducted. As a result, generating instantaneous force by proposed method was realized. © Published under licence by IOP Publishing Ltd.

    This paper describes the development of bellows-type artificial rubber muscle and a peristaltic crawling robot attached to a large intestine endoscope using the artificialmuscle. Colorectal cancers can be cured completely if they are discovered early with a large intestine endoscope. While the endoscope can be used to screen and heal this cancer, its operation is difficult. In this study, to solve the difficulties, we propose a peristaltic crawling robot to subserve the endoscope. This robot can automatically move forward and pull up slacks. In addition, this robot can traverse bent pipes such as a splenic flexure because of bellows-type artificial muscle. Unlike other endoscopic robots, our robot can be attached to an endoscope, enabling us to benefit from the endoscope's various functions. In this paper, we fabricated a bellows-type artificial muscle that enables the robot to pass through splenic flexures and apply the bellows-type artificial muscle to the robot. In addition we executed performance experiment in a bent pipe and experiment in large intestine.

    Recently, proposed applications of robots require them to contact human safely. Therefore, we focus on pneumatic rubber artificial muscle. This actuator is flexible, light, and has high-power density. However, because the artificial muscle is flexible, it vibrates when there is a high load. Therefore, we paid attention to the magnetorheological (MR) fluid. We propose a control method of the MR brake considering energy of the manipulator system. By this control method, MR brake dissipates energy leading to vibration of the manipulator. In this paper, we calculated the energy and controlled the MR brake. And, we deliberated the proposal method by simulation using the dynamic model of the manipulator, and experiment.

    In recent years, human and robots have begun to work together in the fields of medical treatment and welfare. In such environments, robots must be designed to operate safely; thus, reducing collision force when collision is occurred with their human colleagues is essential. In this study, a manipulator with opposed-placement-type electrorheological (ER) clutches is designed to reduce the collision force. The main feature of the manipulator is a structure that sandwiches the link between two ER clutches and equips the link with a pneumatic cushion. The input shaft of each clutch is rotated in the opposite direction via a bevel gear and a spur gear from an electric motor. Because the link can be reversed by switching the clutch, the manipulator can operate in high-speed reverse motion. Position control, reverse motion control and collision experiments were performed to test the effectiveness of the manipulator. The reverse motion control experiment revealed that the manipulator can reverse more rapidly than a conventional manipulator, which is only driven by a motor. From the collision control experiment, it was found that the manipulator can reduce the collision force more effectively than the conventional manipulator.

    To elucidate planetary origins and develop suitable bases for human operations, the subsurface of the planets must be investigated. Previously, we have developed a planetary subsurface excavation robot with the peristaltic crawling mechanism. This robot consists of two units; a propulsion unit and an excavation unit. The propulsion unit operates by peristaltic motion of three subunits, while the excavation unit is fitted with an earth auger. However, because underground soil is not smoothly discharged from the spout when it is below surface, this robot cannot continuously perform subsurface excavation. To solve this problem, we have developed a discharging unit that automatically conveys the soil from the spout to the ground surface. In this paper, we explain the function of the proposed discharging unit. Next, we develop the unit and experimentally evaluate its ability to remove underground soil. The unit is then attached to an excavation robot moving under propulsion. We conclude that the discharging unit can operate efficiently below surface.

    Recently planetary exploration that has gathered great attention has a possibility to find trace of life, new substances and origin of our planet especially underground. We have therefore developed a planetary subsurface explorer robot with propulsion and excavation units. The prototype robot demonstrated excellent excavation performance. However, both units have been separately controlled to achieve propulsion and excavation motions. In order to effectively combine these systems, it is therefore desirable to understand an excavation process. The purpose of this study is to reveal the process of the cutting resistance of an earth auger by experiments for the first step. First we conduct two experiments, the pushing force experiment and rotation speed to reveal the excavation process, with a developed experimental device. A torque and vertical force are measured with a 6 axial force sensor as the excavation resistance. Next the excavation resistance of the fish tail comprising the auger head is measured. We observe good excavation results and discuss the excavation process. © 2013 IEEE.

    Recently, flexible and light actuators that mimic muscle fibers have been actively researched. Here, we focused on an electroactive polymer (EAP) dielectric elastomer. To construct the actuator, the dielectric elastomer is rolled into a tube, and extended by applying a voltage across its electrodes. In this paper, we experimentally obtained a static characteristic model of the electrostrictive rubber actuator, and proposed a control method. We then incorporated the actuator into a 1-DOF manipulator, and constructed a controller from a mechanical equilibrium model of this manipulator. Finally, the constructed controller was tested in a series of experiments. The angle of the arm fell below the desired angle because of friction in the joint and the spring characteristics of actuators. However, we confirmed that the controller reduced the influence of the load by torque feedback. We also investigated the influence of joint stiffness.

After the generation of an arbitrary instantaneous force, we were able to control the robot's arm position by applying an equilibrium force on the joint. Furthermore, we were able to control the vibrations of the arm by controlling the MR brake using an evaluation function.

    In this study, we developed a peristaltic crawling robot that can pass smoothly through a 25A 90-degree elbow pipe, whose radius of curvature equals its inside diameter. The actuator of the robot is composed of artificial rubber muscles. The robot performs earthworm-like locomotion by supplying air pressure to the artificial muscles. To enable smooth passage through the elbow pipe, we designed the robot with low friction and devised a variable friction unit with an aluminum sheet. This robot passes through the elbow pipe while retaining speed and maximum friction force as in a straight pipe.

    An artificial rubber muscle as an actuator was paid attention in this study because the manipulator was found to be safe to human when it comes in contact with human. However, this actuator vibrates easily with a late response because of the applied air pressure. Then, the magnetorheological brake that uses the magnetorheological fluid with an early response is built into the joint and controls the vibration. In this article, we have grasped the dynamic characteristics of a manipulator by the construction of a model for improvement in the control performance of the magnetorheological brake. Furthermore, the simulation was performed using the model, and efficient braking of the magnetorheological brake was examined.

    There are diseases of the small intestine such as Crohn's disease or Polyp that cause Intussusception. These diseases were not discovered before using an conventional endoscope and the small intestine was called "The Dark Continent". Recently, these diseases are inspected by a Double-Balloon Endoscope or Capsule Endoscope. However, the method used for these inspections have a few problems. Therefore, we proposed a new method of inspecting the small intestine. Utilizing our past research, we developed a robot for the small intestine using peristaltic crawling. The robot is attached to a conventional endoscope. When the endoscope reaches the small intestine, the robot is detached from the endoscope and moves forward and observes and treats the afflictions. In this paper, we fabricated the prototype and experimented in an acrylic pipe and elastic tube. In addition, we confirmed that the robot and endoscope can be separated in any place.

    Robots have entered human life, and closer relationships are being formed between humans and robots. It is desirable that these robots be flexible and lightweight. For this reason, we studied and developed an artificial muscle actuator using straight-fiber-type artificial muscles derived from the McKibben-type muscles, which have excellent contraction rate and force characteristics. Therefore, we developed a 6-DOF artificial muscle manipulator, which has a wider moveable range than that using McKibben-type artificial muscle. However, this manipulator vibrates when receiving a sudden load, because the artificial muscle is flexible. For this problem, we suggest that control of joint stiffness is effective. In this paper, we controlled joint stiffness of the 6-DOF artificial muscle manipulator, and obtained a compliance ellipse of the end-effector. In addition, this manipulator controlled vibration of the end-effector by changing joint stiffness depending on the position of the end-effector.

    Master-slave systems and human-assisted systems in which robots can work together with humans have been widely developed. Such systems are necessary to communicate human intentions to a robot. Therefore, it is important for these systems to be able to estimate human joint characteristics such as torque, position and stiffness. In this context, we focus on the myoelectric (ME) potential. In many previous studies, an electric motor has been used as an actuator, and the torque and position are estimated from the ME potential. However, the joint stiffness of humans has not been studied extensively. In this study, we propose a method to estimate the stiffness of the human elbow by using antagonistic muscles when an instantaneous load is applied. Furthermore, we apply our method to a 1-d.o.f. manipulator with an artificial muscle. In the case of eccentric contraction, it has been shown that the stiffness of a joint can be estimated solely by an electromyogram of the triceps. Then, the stiffness and angle control of the artificial muscle manipulator that used it as the slave side is proposed. Furthermore, the estimated joint stiffness is set as a desired value for joint stiffness control of the artificial muscle manipulator. Experimental results of stiffness control indicate that the angle and the stiffness of the 1-d.o.f. artificial muscle manipulator can be adequately controlled for a master-slave system. Safer remote control systems can be developed by using this system. (C) Koninklijke Brill NV, Leiden and The Robotics Society of Japan, 2012

    The number of large intestine cancer patients has been increasing steadily. An endoscope can be used to diagnose as well as to treat the diseased part of the intestine. A large intestine endoscope is used mainly to examine cancer of the large intestine. However, many doctors have problems handling an endoscope. To resolve this issue, there is demand for a robotic application to assist in inserting the endoscope and straightening the slack from the intestine. We propose a robot that imitates the peristaltic crawling of an earthworm and uses an artificial rubber muscle as an actuator. By attaching the robot to an existing endoscope, it will be possible to move the endoscope forward and pull up the intestine simultaneously, while retaining the functions of the existing endoscope. In this paper, we test the forward and pulling movements of a sliding-air-tube robot in a large intestine of model to evaluate its performance. From these experiments, the robot equipped with the endoscope of 11 mm in the diameter can be moved at the speed that satisfies it. Further, air-emit function is added to this robot and its performance in the large intestine of a dead swine is evaluated. Result of accomplishing experiment by using imitation of endoscope of 8 mm, this robot showed that it had the ability to move the endoscope.

    Pipe failures resulting from corrosion or other forms of deterioration are a common occurrence. To combat this problem, in-pipe inspections are required Fiberscopes are currently used as industrial endoscopes to inspect pipes for defects. However, because of friction, fiberscopes cannot be inserted into pipes that are more than 15 m long or have complex shapes such as elbows. Therefore, in-pipe inspection robots need to be self-propelling.
    In this study, we developed two robots that mimic the peristaltic crawling motion of earthworms as a locomotion mechanism. These robots consist of several units. Each unit has an artificial muscle that is driven by pneumatics. Each of the robots has an internal space to hold inspection apparatus. We conducted several experiments with a robot inside a 25A acrylic pipe (diameter: 27 mm). These experiments were conducted to examine the relationship between the locomotion speed and motion patterns. The robot was able to pass through the elbows that were positioned in both horizontal and vertical planes. In addition, we developed a smaller robot for a 15A pipe (diameter: 16 mm) to examine the relationship between the locomotion speed and motion patterns. Our findings exhibited good performance by the robots.

To obtain high-speed motion, it is necessary to increase the actuator output as the robot weight increases. In contrast, humans perform motions with instantaneous force-as in a jump or throw-via variable rheological characteristics. We developed a one-degree-of-freedom manipulator with a variable rheological joint using a straight-fiber-type artificial muscle and a magnetorheological (MR) brake. Then, we created a nonlinear dynamic characteristics model of this manipulator and proposed a method for generating instantaneous force. Furthermore, we validated the proposed method by experiment and simulation. The model reproduced the manipulator system characteristics, and the dead and rise times decreased compared with the conventional method. Furthermore, we controlled the manipulator arm motion by controlling the MR brake both experimentally and via simulation. The results were quite satisfactory.

    An omnidirectional movement mechanism is needed that can move a robot in a narrow complicated passage. However, existing mechanisms cannot achieve stable operations. We noted that a snail uses traveling waves and can achieve a stable operation because of a large landing area. We therefore developed a traveling-wave-type mobile robot (TORoIII) using a snail's locomotive mechanism. However, the directions of the robot were restricted by the number of units, i.e., the directions corresponded to the number of units. In addition, to use this robot as an autonomous robot, self-localization method and path planning method are required. At present, these methods for this robot have not been proposed. In this study, we propose a new perfectly omnidirectional locomotion strategy for TORoIII. In addition, we propose odometry based on kinematics and path planning method based on potential method. Furthermore, we propose online path tracking method using the odometry. We experimentally confirmed the utility of these proposed methods.

    This paper describes the development of an endoscopic robot attached to a large intestine endoscope.
    Colorectal cancer can be cured completely if they are discovered and treated early with a large intestine endoscope. Conventional endoscope can screen and heal inside of the intestine. But, operation of the endoscope is hard for doctors; the training is needed many times. In addition, even if experienced doctors, it occasionally spends one hour for this operation.
    In this study, in order to solve these problems, we propose the endoscopic robot using peristaltic crawling with bellows-type artificial rubber muscle. This robot can move forward automatically and pulling up the slack. In addition, because of bellows-type artificial rubber muscle, this robot can also pass bent pipes like splenic flexure. Unlike another endoscopic robot, our robot can be attached the endoscope. Thus we can use various function of the conventional endoscope.
    In this paper, in order to pass splenic flexure, we describe that we fabricated bellows-type artificial muscle. Next, we experimentally confirmed that the robot can pull up the sigmoid colon of the large intestine of dead swine that is arranged in the human body. In addition, in a large intestine model, we reach a endoscope to the cecum with the robot.

    A pump capable of transporting high-viscosity fluids and solid-liquid mixtures is required in various industrial settings, include cement plants, sewage treatment plants and food plants. In addition, growing demand in the medical field. Turbine-type pumps, piston-type pumps and squeeze-type pumps are often used to transport high-viscosity fluids and solid-liquid mixture. However, these types of pumps have disadvantages. Turbine-type pumps cannot exert a high discharge pressure and turbine damage caused by stone
    piston-type pumps are usually considerably large, because high pressure is needed to transport large quantities of fluid
    squeeze-type pumps are a large and complex equipment. Furthermore, it can be difficult to arrange the bent pipes required by these systems because of high friction between the fluid and the pipe walls. Hence, an innovative transport system is desired. In this paper, we focus on bowel peristalsis as a model for a mechanism that can transport fluids, such as sludge with little water. We developed a peristaltic pump based on the bowel mechanism by using an artificial rubber muscle, and confirmed its capabilities. In addition, we develop new tube to achieve a perfect close of the tube, and confirm the basic characteristics of the new tube. Finally, we measure the suction pressure and confirm the perfect close of the tube. © 2012 IEEE.

    Stirred tanks used in various fields for chemical reactions have double structures and the interior temperatures of the tanks are adjusted by injecting heat media or refrigerants into the interspace of two walls. However, because of impurities included in the medium, a large amount of excrescences are formed on the inner wall, which prevent heat transfer. Moreover, there are currently no techniques or robots that can inspect or clean the interspace. This is owing to the anomalous environment: between two vertical narrow planes. Therefore, we developed a peristaltic crawling robot that realizes the motion by the expansion and contraction of pneumatic artificial muscles for the maintenance of stirred tanks. In this study, we first focused on realizing movement between two vertical narrow planes. We also realized stable horizontal locomotion with a speed of 2.53 mm/s and a new turning motion between two 50-mm-wide vertical planes. © 2012 IEEE.

    In this study, we aim to improve the safety during collisions between a robot and a person by controlling the electric field applied to the ER clutch built into the joint of the robot after a collision. We add energy dissipation to the robot arm by increasing the friction in the ER clutch. Moreover, we examine recoil of a robot arm just after a collision by reversing a motor. In this article, we report on several reversal experiments conducted on a one-link arm that does not undergo collision, and we investigate the energy dissipation effect that can be generated by an ER clutch.

    Robots have entered human life, and closer relationships are being formed between humans and robots. It is desirable that these robots be flexible and lightweight. For this reason, we studied and developed an artificial muscle actuator using straight-fiber-type artificial muscles derived from the McKibben-type muscles, which have excellent contraction rate and force characteristics. However, these muscles have highly nonlinear characteristics, as well as high compliance and a strong hysteresis characteristic. Hence, it is difficult to control the artificial muscle manipulator. In this study, we developed nonlinear dynamics model of the artificial muscle, investigate nonlinear dynamics characteristics of the muscle. In addition, considering nonlinear dynamic characteristics of the artificial muscle, we implore control speck of 6-DOF artificial muscle manipulator.

    In recent times, the chances of robot-human contact have increased; hence, safety is necessitated with regard to such contact. Thus, manipulators using a pneumatic rubber artificial muscle, which is lightweight and flexible, are studied. However, this artificial muscle manipulator has faults such as slow response and limited instantaneous power due to operation by air pressure. Because of these faults, uncontrollable vibrations can occur, leading to instability in the arm when an object is held and lifted. In this study, an artificial muscle manipulator with one DOF and a variable rheological joint mechanism using MR fluid is developed. Vibration control of the arm using MR fluid is realized when an object is held and lifted, confirming the reduction in vibration due to the MR effect.

    A lot of plumbings such as gas pipes and water pipes exist in public utilities, factories and so on. The use of an omni-directional camera which can take images of 360 deg in surroundings at a time is effective for pipe inspection. However, shape measurement is difficult only with the omnidirectional camera. Therefore, in this paper, we propose a reconstruction method of a piping shape by using a rangefinder constructed with an omni-directional camera and an omnidirectional laser. The rangefinder is mounted on an earthworm robot. Our method calculates 3-D coordinates by the light section method. By integrating the 3-D coordinates with the information of camera motion estimated by the structure from motion technique, the shape of the pipe is reconstructed. The validity of the proposed method is shown through experiments. © 2011 IEEE.

    Robots have become an integral part of human life, and the relationship between human and robots has grown closer. Thus, it is desirable for robots to have characteristics similar to those of humans. In this context, we paid attention to an artificial muscle actuator, and studied and developed straight-fiber-type artificial muscles derived from McKibben-type muscles, which have an excellent contraction rate and force characteristics. We developed a manipulator with 6-d.o.f. using artificial muscles as actuators and considered its position control. However, artificial muscle manipulators are susceptible to load torque because they do not use any gears and are flexible. Joint stiffness must increase because accurate position control of the artificial muscle is difficult. Stiffness control must respond quickly to achieve coordination with human activity; however, conventional stiffness control by torque-based methods depends on the position control response. Therefore, position and stiffness control need to be independent of each other. In this study, we propose a new method of joint stiffness control, which adds estimated stiffness to the torque-based method. In addition, we performed experiments examining the load response to steady-state and instantaneous loads. (C) Koninklijke Brill NV, Leiden and The Robotics Society of Japan, 2011

    Recently, humans and robots have started working together in the field of medical treatment and welfare. In such a work environment, it is required that robots operate in a safe manner that avoids collisions or inadvertent contact with their human colleagues. A three degree-of-freedom (3-DOF) soft manipulator with an electrorheological (ER) clutch and a pneumatic cushion sensor has been developed as a robot arm that meets this demand. The buffer method employed in this manipulator reduces the force of a collision by making its joint flexible when a collision occurs. In this study, the power of such an impact is further reduced by developing a method for highspeed reverse control in the event of a collision. However, this method imposes a load on the electric motor when the arm is working under inertia. This problem is solved by dispersing the energy of the arm by using the friction of an ER clutch that is electrically controlled. In this study, several simulations and experiments are conducted on a 1-link arm without collision. We investigate the effects of energy dissipation and confirm highspeed reverse control in a 1-link arm.

    The transportation of high-viscosity fluid and solid-liquid mixtures is required in various settings, such as food plants and petroleum plants, and in various fields, including the civil engineering field and the medical field. A volume-type pump is often used to transport these fluids. This type of pump is usually quite large, since high pressure is needed to transport large quantities of fluid. Furthermore, it can be difficult to arrange the bent pipes needed by the system, since there is a lot of friction between the fluid and the pipe. Hence, the development of an innovative transport system is desired. We focused on bowel peristalsis as a model for a mechanism that can transport these fluids, such as sludge with little water. In this study, we developed a peristaltic pump based on the bowel mechanism by using artificial rubber muscle and confirmed its capability. In addition, we fabricated a peristaltic pump of six units and conducted liquid transportation experiments as an operational check.

    In this study, an artificial rubber muscle was selected as an actuator because it is safe to be used as a muscle manipulator that comes into contact with the human body. However, this actuator vibrates and can cause delayed responses because of the air pressure that is applied to the manipulation. We built a magnetorheological (MR) brake that uses MR fluid with a fast response into the joint to control the vibration. In this study, we focus on the variable damping of the MR brake. By variable damping of the MR brake, we could apply the brake torque depending on the rotational speed of the arm in response to the artificial muscle manipulator. Moreover, we could control the viscosity coefficient of the manipulator depending on its angle and calculate the optimum brake torque as an indicator. As a result, we found that the manipulator's lifting operation was more stable without any sudden movement. We evaluated various aspects of the manipulator control to determine the best indicator of the viscosity coefficient, and studied the position control of an artificial muscle manipulator using these methods.

    Recent advances in robotics have resulted in robots working in close proximity with humans. As a consequence, safety issues are becoming increasingly important, for example when a collision unexpectedly occurs between a robot and a person. To address such a scenario, a 3-DOF soft manipulator has been developed that incorporates an electrorheological (ER) clutch and a pneumatic sensor. The pneumatic sensor is used to decrease the impact force, while the ER clutch also decreases the collision force by making the robotic joint flexible during a collision. In this study, we aim to further improve the safety during collisions between a robot and a person by controlling the electric field applied to the ER clutch after a collision. We add energy dissipation to the robot arm by increasing the friction in the ER clutch. Moreover, we examine recoil of a robot arm just after a collision by reversing a motor. In this paper, we report on several reversal experiments conducted on a 1-link arm that does not undergo collision, and we investigate the energy dissipation effect that can be generated by an 45ER clutch.

    In recent years, the demand for a robot that plays an active part in medical treatment and nursing has been increasing. The robot that interacts with humans should not only have a high output but should also be safe and flexible. We adopted a pneumatic artificial muscle as an actuator of the robot manipulator to satisfy these requirements. Pneumatic artificial muscles are lightweight and have a high power output. However, a McKibben-type artificial muscle commonly used for this purpose is problematic; therefore, we developed a straight-fiber-type artificial muscle that surpasses the McKibben-type in regard to its output. We also developed a two degrees of freedom artificial muscle manipulator with a differential gear mechanism, which can double the stiffness output of the conventional manipulator. Moreover, we propose a control system for this manipulator about joint angle and stiffness. We controlled the joint angle using the PI control method, and controlled joint stiffness by the torque feedback control method. Finally, we performed experiments to verify control system.

However, this actuator occurs easily the vibration, and is late the response because of applying the air pressure. Then, the MR brake that uses the MR fluid with an early response is built into the joint, and controls the vibration. In this paper, we have grasped a manipulator's dynamic characteristics by construction of a model for improvement in the control performance of MR brake. Furthermore, the simulation was performed using the model and efficient breaking of MR brake was examined.

    This paper describes the development of an endoscopic robot. A number of patients of a colorectal cancer increase. However, colorectal cancer can be cured completely if they are discovered and treated early with a large intestine endoscope. In inspecting the large intestine, doctors use the endoscope because it can supply the air and water, and treat the large intestine. However, because the large intestine is so long and has a slack as the sigmoid colon and transverse colon, doctors must straighten the slack in order to insert the endoscope. Because of this hard operation, patients feel pain and get uncomfortable. In addition, the training is needed about 150 times, even if experienced doctors, it spends one hour for this operation. In this study, in order to solve these problems, we developed endoscopic robot with artificial rubber muscle using peristaltic crawling. Unlike another endoscopic robot, our robot can attach the endoscope. For other function of the endoscope, moving forward automatically and pulling up the slack can be feasible. In this study, we confirmed that the robot can pull up the sigmoid colon of the large intestine model that is arranged in the human body model. Next, in order to move forward in the large intestine of dead swine, we fabricated new mechanism. Then, we executed two experiments: one is the experiment of moving forward, and other is the experiment of pulling up the intestine. From those experimental results, the moving forward and pulling motion was confirmed. © 2011 IEEE.

Next we develop an excavation unit with a tapered earth auger and a propulsion unit with dual pantograph. Several experiments are performed to demonstrate these features. Finally, we develop a subsurface explorer robot with propulsion and excavation units. Excavation experiments are successfully conducted using the excavator alone and at lighter weights. We show that the excavator can begin boring from a launcher, and in case of excavator of 1/6 of its own weight, it successfully excavates at the same depth as in its own weight. This demonstrates that this novel excavator is expected to accomplish future missions on other planets and the moon. © 2011 IEEE.

    A master-slave system has been used to operate a robot. This system is necessary to communicate human intentions to the robot. In this context, we focus on Myo-Electric (ME) potential. In many previous studies, a motor is used as an actuator, and the torque and position are estimated from the ME potential. However joint stiffness, which humans can change, is not considered. It is possible to solve this problem about the actuator by using the artificial muscle that we have studied, because the muscle can adjust joint stiffness. Therefore, it is necessary to estimate the joint stiffness of humans. In this study, we propose a method to estimate the stiffness of a human elbow. Furthermore, we apply our method to the 1-DOF manipulator of the artificial muscle. © 2010 IEEE.

    The global water shortage has recently been debated at the United Nations. The main cause of this shortage is the excessive use of water resources by humans. Therefore, a positive approach to saving water is needed. Much water is used to flush toilets in homes. Thus, it is necessary to develop a sewage disposal system that saves water. We focused on the bowel peristalsis as a model for a mechanism that can transport sludge with little water. In this paper, we suggest a mechanism that uses such a pump and confirmed its capability. In addition, we fabricated a peristaltic pump of six units, and conducted liquid transportation experiments as an operational check.

    The number of large intestinal cancer patients has been increasing steadily. An endoscope is used in diagnosis as well as in treatment of the diseased part of the intestine. A large intestine endoscope is used mainly for the inspection of large intestinal cancers. However, many doctors experience issues in handling the endoscope. Thus, a robotic application to assist in inserting the endoscope and remove slack from the intestine is anticipated. We propose a robot that mimics the peristaltic crawling of earthworms and uses an artificial rubber muscle as an actuator. This paper describes how we performed four experiments: 1) determining the relationship between the contraction/expansion values and inner pressure of the artificial muscle; 2) forward movement tests in an acrylic tube; 3) determining the robot's ability to pull an acrylic tube; and 4) forward and pulling movement tests in a large intestinal model. Satisfactory performances were obtained from the experiments.

    In this study, we present an omni-directional mobile robot based on the locomotion of a snail. The snail moves by propagating traveling waves from its tail to its head. If it were possible to propagate a traveling wave in several directions, an omni-directional mobile robot could be realized. Since the locomotion mechanism of the snail involves moving a larger area than in the case with other creatures, it is able to move not only on irregular ground such as swamps, but also on walls and ceilings. We have developed an omni-directional mobile robot that makes use of a traveling wave and have derived a kinematical model for locomotion strategy. In experiments, the robot showed good performance, as described in this paper. ©2010 IEEE.

    Development of a small and light robot that can excavate by itself is required for planetary exploration. The robot conducts in situ analysis of geological samples and deploys devices for measurement and observation to investigate the underground of a planet. Although excavation robots have been developed, they have satisfied a demand that did not yet exist. Then we focussed on the peristaltic crawling of an earthworm as a locomotion mechanism and developed a small excavation robot. First, we proposed that the excavation robot should consist of two parts: propulsion and excavation. We use an earth auger for the excavation part. The propulsion part moves by peristaltic crawling and it must restrain the unit against the rotation reaction of the earth auger. Therefore, we constructed a peristaltic crawling robot that has a dual-pantograph mechanism. Finally, we measured the basic properties and features of a unit working in dirt. Also, we confirmed that the robot can move vertically, both upwards and downwards, in an acrylic pipe. Good performance was observed in the experiments.

    In recent times, the chances of robot-human contact have increased; hence, safety is necessitated with regard to such contact. Thus, manipulators using a pneumatic rubber artificial muscle, which is lightweight and flexible, are studied. However, this artificial muscle manipulator has faults such as slow response and limited instantaneous power due to operation by air pressure. Because of these faults, uncontrollable vibrations can occur, leading to instability in the arm when an object is held and lifted. In this study, an artificial muscle manipulator with 1 DOF and a variable rheological joint mechanism using MR fluid is developed. Vibration control of the arm using MR fluid is realized when an object is held and lifted, confirming the reduction in vibration due to the MR effect.

    A reliable control method is proposed for multiple loop control system. After a feedback loop failure, such as case of the sensor break down, the control system becomes unstable and has a big fluctuation even if it has a disturbance observer. To cope with this problem, the proposed method uses an equivalent transfer function (ETF) as active redundancy compensation after the loop failure. The ETF is designed so that it does not change the transfer function of the whole system before and after the loop failure. In this paper the characteristic of reliable control system that uses an ETF and a disturbance observer is examined by the experiment that uses the DC servo motor for the current feedback loop failure in the position servo system. © 2009 The Institute of Electrical Engineers of Japan.

To cope with this problem, the proposed method uses an equivalent transfer function (ETF) for active redundancy compensation after loop failure. The ETF is used to maintain the transfer function of the entire system the same before and after loop failure. In this study, the characteristics of a reliable control system that uses an ETF were examined experimentally. A position servo system including a disturbance observer is used in the experiment. In case of feedback loop failure, the control system could not be stabilized using the disturbance observer alone; however, the ETF stabilized the control system after feedback loop failure.

    Purpose - An earthworm moves by peristaltic crawling which brings a large surface into contact during motions and requires less space than other mechanisms. A peristaltic crawling is suitable for moving in excavated space by an anterior (front) of a robot. Therefore, a peristaltic crawling robot is useful for an underground explorer. The purpose of this paper is to develop a peristaltic crawling robot with several parallel links and compare with motion of an actual earthworm. Then we had some experiments on a plane surface and in a tube, and in vertical perforated dirt.
    Design/methodology/approach - The proposed robot, which consists of several parallel mechanisms, has four units for being controlled in 3-DOF. A unit expands in a radial direction when it contracts to increase the friction between the unit and surroundings. Dustproof covering is attached for preventing dirt from getting inside units. Locomotion mechanism is as the same as an actual earthworm's peristaltic crawling. The robot makes an anterior unit contract, and then the contraction propagates towards the posterior (rear). Therefore, it requires no more space than that of an excavation part on the front of the robot.
    Findings - It was found that three units of robot consists of several parallel mechanisms had wide range of manipulation; four units of robot moves with peristaltic crawling compared with motion of an actual earthworm. it was confirmed that the robot could turn on a plane surface and move upward and downward in a vertical pipe. Finally, the robot could move in vertical perforated dirt faster than in a pipe.
    Originality/value - The robot is designed with several parallel links and equipped with dustproof covering. The locomotion of an actual earthworm is videotaped and analysed for comparing with the analysed movements of the robot. it was confirmed the robot could move with peristaltic crawling and turn on a plane surface. In addition, it was confirmed that some experiments were done in a narrow pipe and in vertical perforated dirt.

    Robots have become an integral part of human life, and the relationship between humans and robots has grown closer. Thus, it is desired that robots have characteristics similar to humans. In this context, we paid attention to an artificial muscle actuator. We used straight-fiber-type artificial muscles, derived from the McKibben type, which have excellent characteristics with respect to the contraction rate and force. We developed a 6-DOF manipulator actuated by a straight fiber artificial muscle. Furthermore, we tried to control the manipulator position by considering its characteristics.

    In recent years, robots have been used in medicine and everyday life. Therefore, it is desirable that these robots be flexible and lightweight. For this reason, we have studied and developed straight-fiber-type artificial muscles derived from McKibben-type muscles, which have excellent contraction rate and force characteristics. Last year, we developed a manipulator with six degrees of freedom using artificial muscles as actuators, and have considered its position control. However, artificial muscle manipulators are susceptible to load torque because they do not use any gears and are flexible. Joint stiffness must increase because accurate position control of the artificial muscle is difficult. The stiffness control must respond quickly to achieve coordination with human activity. However, conventional stiffness control by torque-based methods depends on the position control response. Therefore, position control and stiffness control need to be independent.
    In this study, we propose a new method of joint stiffness control, which adds estimated stiffness to the torque-based method. In addition, we performed experiments examining load response to the steady state and instantaneous loads.

    A reliable control method is proposed to cope with an unstable fluctuation caused by a loop failing in a multiple-loop control system. In this study, reliable control was applied to a Position servo system that was made to examine the reliable control method in an industrial machine and study its characteristics. The system uses an equivalent transfer function (ETF) for active redundancy compensation after a loop failure and has a fault detection and isolation scheme for the loop failure. The principle of the transfer function is that when a sensor is broken down and the sensor information cannot be acquired, the transfer function of the system differs from a transfer function of the normal system, hence the compensator (the ETF) that conforms the transfer function of the failing system to the transfer function of the normal system stabilizes the failing system. The ETF compensates for the failure of a system using software such that the failing system continues to be in control by switching the normal control program to the control program including compensation for the failing. In this study, the system including the ETF is analysed experimentally. ©2009 IEEE.

For this reason, we studied and developed an artificial muscle actuator using straight-fiber-type artificial muscles derived from the McKibben-type muscles, which have excellent contraction rate and force characteristics. However, these muscles have highly nonlinear characteristics, as well as high compliance and a strong hysteresis characteristic. Hence, it is difficult to control the artificial muscle manipulator.
    In this study, a mechanical equilibrium model is introduced to control this manipulator, and the position control characteristic is linearized, making compliance control possible. In addition, considering dynamic characteristics of the artificial muscle, we apply an "inner model control" for position control.

This locomotion mechanism is in contact with a large area on the ground when the robot moves. Furthermore, the amount of space required is less than that for other locomotion mechanisms. Therefore, this mechanism is suitable for not only rescue robots but also exploration robots in the ground and automatic endoscopic robots.

    This article describes a mathematical model of a pneumatic artificial muscle reinforced by straight fibers. The pneumatic artificial muscle is lightweight and high power. In addition, it is possible for it to emit exhaust into the atmosphere because the transmission medium of its energy is air, and it needs neither a tank nor maintenance like hydraulic equipment. In addition, safety to a person and the environment is high because the base of the actuator is a soft polymeric material even if damage to the artificial muscle is caused. On the other hand, because the device is composed of a thin film cylinder, and is easily influenced by outside power for the conversion of the volume change in rubber into physical contraction axially, and its passive character is strong, precise positional control is difficult. However, the living thing that has a verbose degree of freedom enables minute motion and walking, etc. by skillfully adjusting to avoid impedance, because it understands its own muscular characteristic beforehand. Similarly, it is thought that the precise positional control is possible by understanding the characteristics of an artificial muscle beforehand. In this research, it is assumed that the expansion shape of the pneumatic artificial muscle that we developed from the pressure distribution is equivalent to the centenary curve, and its model is based on dynamic balance. The result shows the effectiveness of control of an artificial muscle that uses highly accurate calculations and models.

Drilling robots have to carry the excavated fine sand, regolith backward because of the high density. Therefore a new scheme is proposed, to move forward under the soil by making use of reactive force caused by pushing the discharged regolith. The first simple experiments demonstrate the effectiveness of the proposed method.

    This paper reports on the position and force control of pneumatic artificial muscles reinforced by straight glass fibers. This type of artificial muscle has a greater contraction ratio and power and a longer lifetime than conventional McKibben types. However, these muscles are highly non-linear
    hence, it is difficult to use them in a mechanical system. Furthermore, this actuator has a high compliance characteristic. Though this characteristic is useful for human interactions, the position and force of this actuator cannot be easily controlled. In this paper, a mathematical model of this type of artificial muscle is proposed, and the relationship between design parameters and control specifications is realized. In addition, the position and force based on the mathematical model are determined and applied to artificial muscle linearization. © 2007 IEEE.

    Recently, as robots and humans have increasingly come to share common spaces, especially in the fields of the medical and home automation, it has become necessary to consider the frequent physical collision of robots and humans. However, many robot joints employ actuators with high-ratio gear trains. Therefore, when this type robot comes into human contact it may cause pain. This study describes the development of a manipulator using a smart flexible joint employing ER fluid and a pneumatic cushion having a sensor function. As well, position control and collision experiments were performed regarding the developed manipulator. The experimental results demonstrate the manipulator's effectiveness.

    In recent years in the field of bio-mechatronics, a robot that imitates a creature&apos;s motion has been developed, In this study, we present a locomotion robot based on locomotion of snail. The snail moves by propagating traveling waves from tail to head. If it is possible to propagate a traveling wave in many directions, an omni-directional mobile robot could be realized. Since the locomotion mechanism of the snail involves moving a larger area than in the case with other creatures, it is able to move not only on irregular ground such as swamps, but also on walls and ceilings. We have developed an omni-directional mobile robot that makes use of a traveling wave and have confirmed that the robot can move in many directions using a traveling wave.

    This paper describes experimental comparison between a conventional McKibben type artificial muscle and a straight fibers type artificial muscle developed by the authors. A wearable device and a rehabilitation robot which assists a human muscle should have characteristics similar to those of human muscle. In addition, because the wearable device and a rehabilitation robot should be light, an actuator with a high power/weight ratio is needed. At present, the McKibben type is widely used as an artificial muscle, but in fact its physical model is highly nonlinear. Further, the heat and mechanical loss of this actuator are large because of the friction caused by the expansion and contraction of the sleeve. Therefore, the authors have developed an artificial muscle tube in which high strength glass fibers have been built into the tube made from natural latex rubber. As results, experimental results demonstrated that the developed artificial muscle is more effective regarding its fundamental characteristics than that of the McKibben type
    the straight fibers types of artificial muscle have more contraction ratio and power, longer lifetime than the McKibben types. And it has almost same characteristics of human muscle for isotonic and isometric that evaluate it dynamically.

    At present, there are various kinds of locomotion mechanisms of robots such as bipedal locomotion, locomotion on wheels, and meandering. All of these mechanisms need a lot of space. But the locomotion mechanism which needs only a slight amount of space is the peristaltic crawling of earthworms. Moreover, this is more stable than any other locomotion mechanisms. Therefore, we pay attention to the peristaltic crawling of earthworms, which will replace the mechanisms of locomotion on wheels or on foot, aiming to develop an earthworm type robot mobile on unleveled ground, narrow roads, in a heap of rubble, or inside the tubes of nuclear power plants. This paper reports on the characters of pneumatic artificial muscle actuator suggested by us, the design of an experimental peristaltic crawling type robot using the actuators, and their evaluation results.

    In the field of bio-engineering the aim of developing new machines which utilize the motion and control of organisms as a model is attracting attention. This technology is pursued by paying attention to various shapes and movements of organisms and autonomous system of organisms that act in response to the environment surrounding them, and by mechanically elucidating the locomotion mechanism, propulsive mechanism, nerve system and sensation system for these organisms. On the other hand, in the field of hydrodynamics, magnetic fluid that changes its apparent viscosity depending on the magnetic field has been developed, and its utilization is under trial in various fields. Attention has been paid to the peristaltic crawling of the earthworm as a transport function in place of wheels or ambulation, and based on these observations a micro-robot running inside a tube using magnetic fluid has been developed. In this micro-robot, individual cells corresponding to the earthworm's segment are composed of a natural rubber tube sealed with water-based magnetic fluid, and several cells are connected with elastic rods made of natural rubber. The feature of this micro-robot is that its structure is simply composed, and it can be controlled with external wireless force, by providing it with moving magnetism from the outside. This paper presents the analytical result on the peristaltic crawling of an actual earthworm and the evaluation result for the transport mechanism of a prototype micro-robot moved by an external magnetic field.

    Homogeneous electro-rheological (ER) fluid is one of the intelligent fluids, having properties by which their apparent viscosity coefficient can be controlled according to the strength of an electric field applied to them. However, the ER effect of the fluid is easily changed by shear rate variation or temperature variation. Therefore, it is desirable for this fluid to be compensated by a feedback controller considering its dynamic characteristic.
    In this study, a continuous and accurate viscous control method is proposed, in order to enable a more effective use of the ER fluid, and demonstrate the application of the control method to a developed homogeneous ER clutch using a personal computer.
    The results of our experiment clearly show that the viscous coefficient of the clutch has been accurately and speedily controlled to the desirable viscous coefficient by the proposed control method. Therefore, by applying the proposed control method, it is possible to obtain a reliable ER device without being influenced by variations of this fluid property. (C) 2002 Elsevier Ltd.

    The viscous coefficient of a homogeneous ER fluid can be changed by the application of an electric field. However, the ER effect of the fluid is easily varied by temperature variation. Therefore, an envelopment and time in which the fluid is applied is limited. In this paper, we examine the influence of the thermal effects induced on the fluid by the device, in order to construct more reliable homogeneous ER devices. We discuss two kinds of thermal effects caused by joule heat and the dissipation of viscous energy. The results of simulations and experiments suggest that most of the exothermic elements of the homogeneous ER fluid are caused by the dissipation of viscosity energy in the fluid. Therefore, it seems reasonable to drive the clutch at a low rotating speed for short periods. We think that a robot arm for impedance control is more effective than a damper for vibration control.

    This paper reports the development of a pneumatic artificial muscle based on biomechanical characteristics. A wearable device and a rehabilitation robot which assists a human muscle should have characteristics similar to those of human muscle. In addition, because the wearable device and the rehabilitation robot should be light, an actuator with a high power/weight ratio is needed. At present, the McKibben type is widely used as an artificial muscle, but in fact its physical model is highly nonlinear. Further, the heat and mechanical loss of this actuator are large because of the friction caused by the expansion and contraction of the sleeve. Therefore, the authors have developed an artificial muscle tube in which high strength Kevlar fiber has been built into the silicone tube. However, its contraction rate is smaller than actual biological muscles. In this study, an artificial muscle with a high contraction rate was developed by using natural latex rubber as the tube material. Since the elasticity of this material is smaller than that of silicone, characteristics similar to those of an actual muscle can be expected. Experimental results demonstrate the effectiveness of this artificial muscle regarding its fundamental and biomechanical characteristics.

    The purpose of this study is to apply the variable damping impedance control to semi-active system using the homogeneous ER (Electro-rheorogical) fluid. A homogeneous ER fluid is constituted by liquid crystal or polymer liquid crystal, and it can change the apparent viscosity under a Newtonian fluid by applying the electric field. Then, when the fluid is applied for device of the machine system, the system can be used as a variable viscous damper. However, these systems have a lot of parameter variations or nonlinear elements. Therefore, some feedback compensations are necessary for these systems to keep up more precisely viscosity.&lt;br&gt;In this paper, we apply the force-based damping control to the homogeneous ER clutch in order to use the characteristics of the fluid enough. We apply the damping control based on the force control to keep up more precisely viscosity. The result of our experiment clearly has shown that the viscosity of the clutch is more certainly controlled by the force-based impedance control.

    Electro-rheological (ER) fluid is a member of the family of intelligent fluids, and it has the character that the apparent viscosity can be controlled according to strength of an applied electric field. Various applications using ER fluid have been developed. Recently, the research on whether ER fluid can be applied to the area of the motion controlof robotics has been performed. For example, we see that robots in factory applications have two links. For the sake of safety, it is necessary to create an enclosure around the robot, since it is not possible for humans to approach large-capacity robots. Thus, we considered that the robot armwould not injure a human if it was possible for the robot arm to bend softly when making human contact, with the force applied at the arm tip skillfully controlled at the joint. In orderto realize this motion, we will develop an actuator build into the joint, and we examined the control method (impedance control) of the robot arm. In this paper, we developed a one-shaft type ER clutch to be installed at the joint division of a robot arm. The developed ER clutch is stronger than the conventional ER clutch in terms of radial motion. Further, we examined the fundamental characteristics of the developed ER clutch in order to apply impedance control to it. The results of our experiment show that the coefficient of viscosity is directly proportional to the applied electrical field. Therefore, it is concluded that the clutch is able to be controlled by impedance control. © 2001, The Institute of Electrical Engineers of Japan. All rights reserved.

    Recently, it is popular to study about ER fluid in a field of mechatronics and fluid mechanics. An ER fluid is one of the smart fluid, and it has the character that the apparent viscosity can be controlled according to strength of an applied electric field. We also have already developed of the one shaft type ER clutch using a homogeneous ER fluid that is one of the ER fluids. The homogeneous ER fluid has a character that the particle does not subside and the gap between electrodes can be narrowed due to be able to get the shearing stress in the same electric field. In addition, it also has a character that its viscosity is susceptible to the temperature variation. However, there are no reports about the temperature characteristics for the clutch using the homogeneous ER fluid. In this paper, we study about thermal characteristics of the clutch using the homogeneous ER fluid. First, we discuss about the torque performances of the homogeneous ER clutch for the increasing its temperature. Here, it was found that the output torque of the clutch depends on the temperature variation. Next, we also discuss about an exothermic element of the homogeneous ER fluid given by the clutch. The result of experiment and simulation clearly shows that the most of exothermic elements of the homogeneous ER fluid is caused by the dissipation of viscosity energy in the fluid. As a result, suitable using method for the homogeneous ER clutch seems reasonable to drive the clutch with low rotating speed for the short time. © 2001, The Institute of Electrical Engineers of Japan.

    An omnidirectional movement mechanism that can move a robot in a narrow complicated passage is needed. However, existing mechanisms cannot achieve stable operations. We noted that a snail uses traveling waves and can achieve a stable operation because of a large landing area. Therefore, we previously developed a traveling-wave-type mobile robot (TORoIII) using a snail's locomotion mechanism. In this paper, we proposed locomotion strategy in curve form to move the robot in the narrower passage. In addition, we conducted the locomotion experiment. As a result, the locomotion of TORoIII could be controlled. Also, this paper explains the mechanism of TORoIII and modeling the shape of the robot.

    Hydraulic control systems are used in most industries where heavy objects are manipulated or large forces are exerted on their surroundings. Recently, a positioning control of electrical hydraulic servo system is been applying a robust control theory which is strong for parameter variations or nonlinear elements, instead of as usual a PID control used in widely industries. The purpose of this research is to evaluate several robust control performances and investigate their aptitude for the oil hydraulic system.&lt;br&gt;In the first paper, we proposed several evaluation methods and standard of designs considering a characteristic of the electrical hydraulic system, and decided system parameters for three kinds of robust control systems which are a Disturbance Observer, a Sliding Mode Control (SMC) and a &lt;i&gt;H&lt;/i&gt;&lt;sub&gt;&amp;infin;&lt;/sub&gt; control, according to the several standard of designs. Next, we applied them to the actual electrical hydraulic servo system, and evaluated the difference of the control performance from the point of view of a robustness for load variations as the parameter variations, a characteristic of disturbance cancellation and a control input.&lt;br&gt;In this paper, the control performance of the robust control systems is evaluated, when they are applied to the positioning control of the electrical hydraulic servo system included of the several parameter variations or the nonlinear elements, which are not only the load variations, but also a oil temperature variations, a pressure variations, and a desired value variations. As a result, all of them have shown good robustness in the load variations, the oil temperature variations, the pressure variations. but the &lt;i&gt;H&lt;/i&gt;&lt;sub&gt;&amp;infin;&lt;/sub&gt; control has shown better performance in the desired value variations than other control systems. Further, the SMC has shown good performance in the control input, because it has been smaller than other control systems in the control input.

    Reduction of the noise emitted from the automobile alternator has recently become a serious issue, and tangible especially concerningwi th improvement of the engine noise. In order to design a Quiet automobile alternator, a designer needs to anticipate all important resonant frequencies. We simulated the electromagnetic vibration behavior of the rotor using experimental modal analysis and finite element method analysis. The results obtained are applicable to alternator design for reduction. © 2000, The Institute of Electrical Engineers of Japan. All rights reserved.

    Continuous mixing and conveying technologies for processing solid-liquid mixtures and highly viscous fluids are required in the manufacture of food and medicine. A device featuring such a technology, namely the peristaltic continuous mixing conveyor, has been developed by the authors previously. This device, imitating the movement of intestines, is capable of mixing and conveying content by inflating a rubber tube using air pressure. Herein, we aim to estimate the degree of mixing of the contents via machine learning using data from pneumatic factor sensors installed in this device. However, the low measurement accuracy of these sensors when dealing with compressible fluids makes the mixing degree estimation difficult. Therefore, in this study, to improve the measurement accuracy of the sensing system, we installed an accelerometer that could directly measure the behavior of the rubber tube inside the device without any contact with the contents being required. Upon operation of the device with various objects within it, the sensor angle of the rubber tube was obtained from the accelerometer values for each input. The sensor angle at steady state after air supply was 22.5° greater for the rigid bodies than for the mixtures of powder and liquid. For the powder-liquid mixtures, a linear relationship was demonstrated between the percent concentration of mass and the sensor angle at a steady state. The results suggest that the content of the device can be determined with greater accuracy by using the attitude angle obtained from the accelerometer than from the conventional pneumatic factor sensors.

    Recently, as buildings have become taller, base structures on construction sites have to be excavated wider and deeper. Generally, excavated soil is transported vertically using clamshells. However, clamshells are large construction machines, and their operation is subject to physical and time limitations. In this study, we focused on the intestinal tract, which transports various fluids by muscle contraction and relaxation. We used a peristaltic conveyance system that simulates a peristaltic movement type pump to vertically transfer excavated soil. In a previous study, we successfully lifted low-water content sediments using a watering system that increases the water content ratio of the transported sediment. From the experiments, the lifting conditions were determined according to the type of sediment. However, the relationship between the driving conditions of the device and vertical transport is not known. For practical use of this equipment, the rate of lifted soil should show an improvement. In this study, we investigated the driving conditions of the equipment according to the soil type to further improve the conveyance efficiency. First, we investigated the appropriate position and amount of water added for each soil type. Next, the lifting rate was compared for various patterns under different conditions.

    Mineral resources such as rare earths are deposited 2 to 3 m below the seafloor; for detailed studies to elucidate their origin and existence, it is necessary to collect samples of seafloor sediments. Currently, vertical drilling is commonly used to collect samples, but it is inefficient because the seafloor sediments are widely deposited horizontally. Therefore, we develop a robotic seafloor explorer. In this study, we worked on horizontal drilling as the next stage. First, a mechanical model of the robot's penetration into the ground during horizontal excavation was developed, and the expected challenges of horizontal drilling were discussed based on the model. After that, horizontal excavation experiments were conducted, and the challenges were clarified from the results.

    The mixing and transporting process of a solid–liquid mixture and a high-viscosity fluid is separate batch processes, leading to an increase in maintenance costs and disposal costs. To achieve continuous mixing and transporting process, the authors have developed a pneumatic peristaltic mixing conveyor based on the movement of transporting bolus in the intestinal tract. The proposed conveyer is possible to mix and transport with one device continuously, however, it has not been studied to mix and transport at the same time like the actual intestine does. In this paper, we proposed a congruence which is able to continuously switch between segmental and peristaltic movement in order to achieve a continuous mixing and transporting.

    We proposed herein a method for estimating the mixing state of the contents of a peristaltic continuous mixing conveyor simulating the intestine, developed for mixing and conveying powders and liquids. This study serves to improve a previously proposed method for estimating the mixing state using a logistic regression model with the pneumatic factor sensors installed in the device as inputs. To improve the estimation method, we changed the method of acquiring training data and labeling in the learning model. Moreover, comparison of the estimation accuracy and the result of the proposed method was better than that of the previous method.

    Pneumatic drive systems are widely used in assistance devices and flexible drive robots owing to their characteristics of light weight, high output, and flexibility. However, those devices cannot perform instantaneous operation because those devices have low responsiveness. Then we focus on the physical properties of flammable dimethyl ether (DME), and we considered using combustion of DME to improve the responsiveness of pneumatic drive systems. We developed artificial muscle which is driven by burning DME inside the device. In this paper, we conducted the experiment to investigate the response time and displacement of artificial muscle when DME burned in the device.

    In a virtual reality (VR) space, wearing a head-mounted display can help with the visualization of objects, however, users cannot experience realistic tactile sensations. Recently, several force feedback devices have been developed, including wearable devices that use straight-fiber-type pneumatic muscles and magnetorheological fluids. This allows the devices to render elastic, frictional, and viscous forces during spatially unrestricted movement. Nevertheless, there are two problems. One is that there were items with low scores in the subjective evaluation regarding the discrimination of device weight and force magnitude. The other is the inability to handle many bilateral upper limb movement tasks. Therefore, this study aims to develop a device that can handle movements that interact with both arms.

    This paper describes the results of an inspection test in an actual environment using a wave propagation type pipe inspection robot, PI-Ro II. it has been difficult to inspect pipes with thin, long, and complicated layouts from the viewpoint of both propulsive force (force to push the robot deeper into the pipe) and traction force (force to pull the robot into the pipe). Therefore, we developed PI-Ro II, a compact robot with a mechanism that enables both propulsion and traction forces, and confirmed its inspection performance in a mockup. However, it is difficult to perfectly reproduce the piping conditions actually used in factories with this mockup. To solve this problem, we conducted an inspection test using PI-Ro II in a pipe used in an actual factory, and succeeded in acquiring images of the inside of the pipe and inspecting 3.8 m of pipe, including passage through two consecutive 90-degree bends.

    In the inspection of sewage pipes, it is necessary to prepare a pipeline map in order to efficiently identify the damaged areas, which are often lost so it is necessary to prepare a pipeline map at the same time as the inspection. The authors have previously developed a peristaltic robot for sewer pipe inspection and have estimated the pipe shape using IMU sensors. However, the accuracy of the estimated map was not enough to be put into practice. In this study, we try to improve the estimation accuracy by measuring the information of the position and orientation of the start and end points of the pipeline to constrain the estimated pipeline shape. The authors represent the pipe geometry with only three parameters, and the correction is performed by iterative calculation using the inverse Jacobian matrix.

    In this paper, we proposed the application of a device using a variable viscoelastic joint for training and rehabilitation. By varying the antagonistic angle of the device with respect to the human motion, the training effects with different loads were verified. The proposed device can switch between training and rehabilitation by changing the antagonistic angle. However, the training effect using the variable viscoelastic joint has not been confirmed yet. Therefore, we measured the muscle potential during the movement when the antagonistic angle of the device was changed. As a result, the value of the EMG increased as the angle of the knee joint and the antagonistic angle of the device during the movement increased. It was confirmed that the variable viscoelastic joint can be applied to training.

    With the advancement of space technology, long-term and deep space exploration is being planned with the long-term goal of exploring the Moon and Mars. In order for humans to stay in space for a long time, a regenerative Environmental Control and Life Support System (ECLSS) is required. In the ECLSS, there is a space toilet to reuse excrement. Since the space toilet is used under the microgravity environment, it is difficult to transport and collect excrement by using gravity. Therefore, the authors focused on the peristaltic movement of the intestine. In this paper, we present a new type of peristaltic motion, which is capable of transporting gas-solid-liquid multiphase flow under microgravity conditions. In this paper, a new peristaltic pump is constructed, and comparison experiments with existing peristaltic pumps and confirmation of its performance are carried out.

    Valuable seabed mineral resources such as rare earth elements are deposited 2–3 meters into the deep seafloor, and sampling and analyzing the seafloor is necessary to clarify how they are generated and distributed. We have developed a seafloor robotic explorer that can excavate horizontally and collect samples of rare earth elements, which may enable wide-area exploration as multiple robots could be simultaneously implemented to autonomously search beneath the seabed. The seafloor robotic explorer may excavate sediments such as clay and sand before reaching the rare earth layer. In previous studies, it has been discovered that the rotation speed, penetration force, and characteristics of the sediment affected the excavation resistance. Therefore, we assumed that controlling the rotation speed and penetration force would enable an efficient excavation according to the ground characteristics. Therefore, in this paper, we examined the effect of rotational speed on drilling efficiency using dry silica sand ground.

    Currently, soft actuators are being actively researched. Genellary, soft actuators are more difficult to control than ordinary actuators because of their flexibility. Therefore, there is a need for a sensor that can be unified with the soft actuator and measure the change in shape of large deformations without interfering with the deformation of the soft actuator. In this study, we propose a strain sensor that can measure the displacement of a soft actuator based on a conductive paste with silver as a filler. This paper describes the investigation of the basic properties of conductive pastes using silver filler and the measurement equipment.

    In this paper, a water suction unit which removes residual water was designed and developed to obtain clear images of the inside of sewer pipes from the camera. When PEW-RO V, which was developed in a previous study, inspects sewer pipes, it cannot inspect inside of sewer pipes taken by its camera in residual water. Residual water removal mechanism consists of the water suction pump and the water suction unit. In the experiment, the location of the pump was determined and PEW-RO V with the water suction unit successfully drained the residual water to a level where the camera could acquire images.

    The purpose of this study is to investigate the effects on human fall sensation when a VR fall sensation presentation device is used to decelerate the device during descent. A questionnaire survey using VAS was conducted to evaluate the effects of acceleration and deceleration on the sensation of falling. A questionnaire using VAS was used to evaluate the sensation of falling and the sense of reality depending on the amount of acceleration and the amount of deceleration. The results suggest that, within the range of acceleration used in this experiment, the deceleration of the device does not significantly impair the sense of falling and the sense of reality.

    In recent years, the demand for rocket launching has increased due to the development of space technology. However, using inexpensive rockets is not always possible. Although the cost of solid-propellant rockets is relatively reasonable, safely manufacturing a large amount of solid propellant is difficult, and the manufacturing process is disjointed. Therefore, to achieve safe and continues manufacturing of solid propellant, we have developed the peristaltic mixing conveyor with pneumatic artificial muscle. In Dec.2017, we succeed manufacturing of the over 1kg practical composition propellant by our system, and in Feb.2018, we succeed burning test of it on ground.

    <p>In this paper, evaluation experiment of an antagonistic joint with two artificial muscles is conducted with feedforward controller which is based on the experimental identification model. The previous controller was based on a mechanical equilibrium model which we can understand the characteristics of the artificial muscle. However, the accuracy of the controller was poor, and the calculation is too complex that the sequential calculation cannot keep up with a real time control on a microcontroller. Thus, this paper proposes an experimental identification model whose calculation is simpler, and has a better accuracy than the previous one. Also, the parameters in the model are easily identified by the measurement experiment of the artificial muscle. And apply the feedforward controller which is based on an experimental identification model to the antagonist joint with two artificial muscles.</p>

    In this study, a variable viscoelastic joint system comprising antagonized artificial muscles and magneto-rheological fluid brakes is proposed. This system enables human assisting devices such as robotic exoskeletons to retain structural softness when compared with the existing devices driven by motors and reduction gears, which can only achieve superficial softness. The authors had proposed the system and showed its effectiveness via experiments using a prototype with one degree of freedom in their previous works. In this study, as the next step in designing the human assisting device, a lower body assistive prototype “Airsist I” is introduced. In addition, a control method that can cooperate with the wearer without the need for an additional operation is proposed.

    Wearable force feedback device enables us to dynamically interact with virtual object while moving in wide virtual space. We have developed wearable force feedback device with variable viscoelastic elements; pneumatic artificial muscles and MR brakes. These mechanical elements show quick response by feed-forward control and high power density. In this paper, we tackled on weight saving of the device, and measured basic property again. Afterward, we evaluated whether a subject can distinguish when rendered different frictional force or elastic force. The subject was rendered one of five grade force, and replied which grade that was. A percentage of correct answers were lower at rendering elastic force. This is because the reaction force was change with angular displacement. In addition, the percentage didn't change respect to fixed state and wearing state. The subject could recognize the difference in the size of the force though the device was loaded.

    Various excavation robots have been developed for in-ground planetary investigations. However, there are no reports of any robots designed to discharge excavated soil. Soil discharging is necessary for excavation robots to achieve greater depths and more sustainable excavations. We previously developed a lunar explorer excavation robot that adopted peristaltic crawling as its propulsion mechanism and this robot incorporates a soil-discharging unit. This unit can convey the excavated soil to the ground surface from the borehole during excavation. However, the soil that is carried by the discharging unit is removed by a dust collector with human hand from the unit. In the future, from the viewpoint of automaticity, the soil should be removed automatically. Therefore, in this paper, we propose a novel discharging unit that removes the soil automatically.

    In recent years, demand for launch of the rockets has increased from space development. Although the solid propellant rockets relatively reasonable, it is difficult to safely manufacture a large of solid propellant, and the manufacturing process is non-constant. Therefore, we consider it is more reasonable if it is possible to manufacture the solid propellant safely and continuously. We focused on the movements to mix of the intestinal tract. We have developed a peristaltic pump that based on bowel peristaltic using straight-fiber-type artificial muscle. In this paper, we show it is possible to mix one high viscous fluid and another one same by measuring luminance value, the glass beads that same diameter to be used micro particles in actual manufaction and sodium polyacrylate aqueous solution resemble HTPB (Hydroxyl Terminated Poly-Butadiene) by measuring the glass beads in the solid-liquid mixed fluid.

    The traveling wave type omni-directional wall climbing robot imitates the snail locomotion mechanism. This movement mechanism enables stable motion because of a large contact area. Moreover, because of the magnetic adhesion mechanism used in this robot, this robot can climb ferromagnetic walls. However, this robot can move only on flat surfaces. In this paper, we developed universal joints for moving on curved surfaces and also the traveling wave type omni-directional wall climbing robot using universal joints. Furthermore, we confirmed the performance of this robot through experiments.

    Planetary subsurface exploration has a possibility to find trace of life ,new substances and origin of our planet. We have therefore developed a planetary subsurface explorer robot which has a propulsion unit and excavation. The prototype robot showed good excavation performance. However, both units were separately controlled to achieve the excavation. In order to combine the systems, the process of excavation is required to reveal. This paper describes the process of the cutting resistance from experiments for the first step. A 6 axial force sensor measures the resistance against the excavation part. We carried out two experiments, e.g. the pushing force experiment and rotation speed. They showed good excavation results.

    It is important to investigate the underground of the planets in terms of the elucidation of the planet's origin and a development of the bases that human can work on the planets. Therefore, we have developed a planetary subsurface excavation robot with peristaltic crawling mechanism. This robot consists of two units; a propulsion unit and an excavation unit. The propulsion unit has three subunits using a peristaltic motion. The excavation unit has an earth auger. But, the existing robot can't excavate without a discharging unit because the soil isn't smoothly discharged from a spout when it reaches below surface. So, we develop a discharging unit to solve this problem. Then, we have an excavating experiment with the robot in order to check the capacity of the discharging unit. Thus, we confirmed that the robot could discharge the soil by the discharging unit.

    Recently, the demand for robots that operate in the fields of nursing and human life have increased due to the aging population and falling birthrates. Since these robots are intended to operate near humans, they are preferable to be light, soft and safe. To satisfy these requirements, we adopt a pneumatic artificial muscle as an actuator of robot manipulator. However, the McKibben-type artificial muscles that are most commonly used have several drawbacks. Therefore, we developed a straight-fiber-type artificial muscle, and developed two degrees of freedom artificial muscle manipulator with a differential gear mechanism. However, the interference occurs in unintended directions in this mechanism because the rotation speed of right and left gears respectively differs. To address this problem, we introduce the disturbance observer (DOB) in the control system. We control the response of right and left gears by disturbance observer and reduce the interference.

    In this study, we developed two types of maintenance robots using a pneumatics artificial rubber muscle for a jacket inside a mixing tank. One is an excavation robot for cleaning the inside of the jacket, and the other is a polishing robot for inspecting the walls. The excavation robot consists of five units and four joints. This robot mimics the peristaltic crawling motion of an earthworm. On the other hand, the polishing robot consists of five units, a metal brush and two wing parts. This robot polishes the walls inside the jacket. Three types of experiments were performed with the two robots. One of the experiments was a driving test inside a various vertical walls. Second was an excavation test inside the jacket. Third was to eliminate sediment on the local walls.

    In recent years, the population that requires assistance with walking has increased owing to a decrease in leg muscular power with age. To prevent muscle weakness and expand their sphere of activities, we develop the orthosis for walking assistance using a pneumatic artificial muscle to assist leg muscular power. In order to judge the availability of the orthosis, we measure the effect on assistance quantitatively. EMG and step length are measured with assistance on healthy subject. We observed that the EMG of the sartorius muscle, which helps swing the leg forward, decreased. And step length is increased as a result of assistance. I think these results mean that a person with little muscular strength can walk like a healthy person.

    The 1-inch gas pipes are used in houses and between gas meters and the main pipe which lies under the road, and requires regular inspection. However, an endoscope has the limit of the scope on inspection. In addition, in-pipe robots cannot pass through a 90-degree elbow, whose radius of curvature equals its inside diameter. In this study, we developed the peristaltic crawling robot with pneumatic artificial muscles for 1-inch gas pipes. This robot can pass through the elbow horizontally and vertically. In addition, this robot can be equipped an endoscope. However, this robot cannot pass through the continuous elbows. It lies in the actual environment certainly. In this paper, to use a robot in the actual environment, we developed the robot which can pass through the continuous elbows. We experimentally confirmed that the robot can pass through the continuous elbows.

    Highly rigid actuators such as a geared motor or hydraulic actuator are widely used in industrial robots. To obtain high-speed motion, it is necessary to increase the actuator output as the robot weight increases. In contrast, humans perform motions with instantaneous force-as in a jump or throw-via variable viscoelastic characteristics. Therefore, we developed a manipulator with variable viscoelastic joint using an artificial muscle and a magnetorheological(MR) brake. Furthermore, we generated instantaneous force, and the dead and rise times decreased compared to the conventional method. In this paper, we controlled the arm position after arbitrary instantaneous force by applying equilibrium of force to the joint. Furthermore, we controlled the arm vibrations by controlling the MR brake using an evaluation function. The results obtained were quite satisfactory.

    A pump capable of transporting high-viscosity fluids and solid-liquid mixtures is required in various industrial settings. Turbine-type pumps, piston-type pumps and squeeze-type pumps are often used to transport high-viscosity fluids and solid-liquid mixture. However, these types of pumps have disadvantages. Hence, an innovative transport system is desired. In this paper, we focus on bowel peristalsis as a model for a mechanism that can transport fluids, such as sludge with little water. We developed a peristaltic pump based on the bowel mechanism by using an artificial rubber muscle, and confirmed its capabilities. But this pump changes diameter and length when it transport fluid. So we developed New peristaltic pump and we measure flow rate.

    In a past study, we developed the mobile mechanism of traveling wave propagation for wall climbing robot. This mobile mechanism is able to use the conveying equipment. In case of using this conveying equipment, the conveyance direction changes by the shape of the carriers. Carriers of the shape to step over the waves more than two is conveyed to the opposite direction of the generated wave. On the other hand, carriers of the shape that is smaller than a wave is conveyed to the direction of the generated wave. In this paper, we developed a conveying equipment using the mobile mechanism of traveling wave propagation and performed the experiment.

    Recently, the number of pipe accidents has been increasing. Because most of these were caused by corrosions or deteriorations, in-pipe inspections have been performed with fiber scopes to prevent such problems; however, such pipes cannot inspect in pipes over 14[m] long or in complex pipes. Therefore, in-pipe inspection robots are required for such uses. In this paper, we propose the development of the robot that mimics the peristaltic crawling of earthworms as a locomotion mechanism. In addition, we performed two experiments in a 27[mm] diameter acrylic pipe and a 28[mm] diameter aluminum pipe to examine 1) the locomotion speed of the robot and 2) the relationship between propulsive force and motion patterns.

    In recent years, robots that can substitute for humans in dangerous activities, contributing to safety, cost reduction and efficiency have been developed. For example, a wall-climbing robot can clean and inspect high places, and approach disaster sites where a person cannot reach. In this study, the locomotion of snails is used as an effective wall-climbing mechanism. A snail moves by generating travelling waves with its muscle elasticity and propagating the wave in the direction of movement. Since this locomotion mechanism is in contact with a large area of ground, it is extremely stable. This is advantageous in climbing unstable walls. The proposed robot uses several slider cranks for locomotion and a fan to adhere to the wall by suction. We confirmed that this robot successfully climbs various walls.

    In a nuclear reactor and a chemical plant, since it is very complicated environment with apparatus, it cannot fully function by the manipulator of 6 degree of freedom (DOF). But, trunk can wrap and catch in the thing of any form at the intricate place. The manipulator that has such a function having far more DOF is called a hyper-redundant manipulator. We made the hyper-redundant manipulator constituted of several 3-RRS parallel link mechanisms. This manipulator can be used in the intricate environments described above. It is necessary to understand the whole shape to control this manipulator. In order to grasp the whole shape of this manipulator, the degree of rotation angle of a servo motor and the angle between arm and rod are required. In this report, we did the design improvement to measure the above-mentioned two angles, led the forward kinematics, and grasped the shape of this manipulator.

    In recent times, the chances of robot-human contact have increased; hence, safety is necessitated with regard to such contact. Thus, manipulators using a pneumatic rubber artificial muscle, which is lightweight and flexible, are studied. However, this artificial muscle manipulator has faults such as slow response and limited instantaneous power due to operation by air pressure. Because of these faults, uncontrollable vibrations can occur, leading to instability in the arm when an object is held and lifted. In this study, an artificial muscle manipulator with 1 DOF and a variable rheological joint mechanism using MR fluid is developed. Vibration control of the arm using MR fluid is realized when an object is held and lifted, confirming the reduction in vibration due to the MR effect.

    This paper reports the development of thin straight fibers type artificial muscles. The straight fiber types of artificial muscle have greater contraction ratio and power and a longer lifetime than McKibben types. And the thin straight type artificial muscle is a micro miniaturization of the straight type artificial muscle that is examined ahead in this laboratory. Its outside diameter is from 1.0 to 3.8 millimeters. Therefore it can work in a limited space. For example, it is expected that the muscle would be used for the direction control in the point part of industrial endoscopes. And the robot hand that uses thin type artificial muscles to drive is developed.

    Attention is currently focused on earthworm's locomotion mechanism is called a peristaltic crawling. The amount of space required by this locomotion mechanism is smaller than that of other locomotion mechanisms. Further, it is possible that the locomotion mechanism move on unleveled ground and inside a tube. In this study, we developed the peristaltic crawling robot that can run not only the in a tube but also on a plane surface. And it can actively and passively change the direction. Further we discussed the robot can adapt to variable environment by applying high extension and contraction units to the robot.

    This paper reports the development of thin straight fibers type artificial muscles. The straight fiber types of artificial muscle have greater contraction ratio and power and a longer lifetime than McKibben types. And the thin straight type artificial muscle is a micro miniaturization of the straight type artificial muscle that is examined ahead in this laboratory. It has the outside diameter of 1.2 millimeters and the inside diameter of 0.5 millimeters. Therefore it can work in a limited space. For example, it is expected that the muscles would be used for the direction control in the point part of industrial endoscopes.

    Language:Japanese  

    The purpose of this study is to apply the variable damping impedance control to semi-active system using the homogeneous ER (Electro-rheorogical) fluid. A homogeneous ER fluid is constituted by liquid crystal or polymer liquid crystal, and it can change the apparent viscosity under a Newtonian fluid by applying the electric field. Then, when the fluid is applied for device of the machine system, the system can be used as a variable viscous damper. However, these systems have a lot of parameter variations or nonlinear elements. Therefore, some feedback compensations are necessary for these systems to keep up more precisely viscosity.<br>In this paper, we apply the force-based damping control to the homogeneous ER clutch in order to use the characteristics of the fluid enough. We apply the damping control based on the force control to keep up more precisely viscosity. The result of our experiment clearly has shown that the viscosity of the clutch is more certainly controlled by the force-based impedance control.

    Language:Japanese  

    Using a magnetic fluid, the earthworm-type robot was developed for running the peristaltic movement. In this earthworm-type robot, a cell equivalent to a segment of the earthworm is composed of a natural rubber tube into which a water-based magnetic fluid is sealed up. The cells are connected with rod-like elastic bodies of natural rubber. It was confirmed that this robot can travel in an acrylic tube (inner diameter : 12mm, outer diameter : 14mm) by providing a shifting magnetic field from the exterior. This article will describe the pattern of the peristaltic movement of an earthworm, how our earthworm-type robot moves, the mechanism of its movement.

    Language:Japanese  

    Recently, it is popular to study about ER fluid in a field of mechatronics and fluid mechanics. An ER fluid is one of the smart fluid, and it has the character that the apparent viscosity can be controlled according to strength of an applied electric field. We also have already developed of the one shaft type ER clutch using a homogeneous ER fluid that is one of the ER fluids. The homogeneous ER fluid has a character that the particle does not subside and the gap between electrodes can be narrowed due to be able to get the shearing stress in the same electric field. In addition, it also has a character that its viscosity is susceptible to the temperature variation. However, there are no reports about the temperature characteristics for the clutch using the homogeneous ER fluid.<br>In this paper, we study about thermal characteristics of the clutch using the homogeneous ER fluid. First, we discuss about the torque performances of the homogeneous ER clutch for the increasing its temperature. Here, it was found that the output torque of the clutch depends on the temperature variation. Next, we also discuss about an exothermic element of the homogeneous ER fluid given by the clutch. The result of experiment and simulation clearly shows that the most of exothermic elements of the homogeneous ER fluid is caused by the dissipation of viscosity energy in the fluid. As a result, suitable using method for the homogeneous ER clutch seems reasonable to drive the clutch with low rotating speed for the short time.

    Hydraulic control systems are used in most industries where heavy objects are manipulated or large forces are exerted on their surroundings. Recently, a positioning control of electrical hydraulic servo system is been applying a robust control theory which is strong for parameter variations or nonlinear elements, instead of as usual a PID control used in widely industries. The purpose of this research is to evaluate several robust control performances and investigate their aptitude for the oil hydraulic system.<br>In the first paper, we proposed several evaluation methods and standard of designs considering a characteristic of the electrical hydraulic system, and decided system parameters for three kinds of robust control systems which are a Disturbance Observer, a Sliding Mode Control (SMC) and a H&infin; control, according to the several standard of designs. Next, we applied them to the actual electrical hydraulic servo system, and evaluated the difference of the control performance from the point of view of a robustness for load variations as the parameter variations, a characteristic of disturbance cancellation and a control input.<br>In this paper, the control performance of the robust control systems is evaluated, when they are applied to the positioning control of the electrical hydraulic servo system included of the several parameter variations or the nonlinear elements, which are not only the load variations, but also a oil temperature variations, a pressure variations, and a desired value variations. As a result, all of them have shown good robustness in the load variations, the oil temperature variations, the pressure variations. but the H&infin; control has shown better performance in the desired value variations than other control systems. Further, the SMC has shown good performance in the control input, because it has been smaller than other control systems in the control input.

    Reduction of the noise emitted from the automobile alternator has recently become a serious issue, and tangible especially concerning with improvement of the engine noise. In order to design a quiet automobile alternator, a designer needs to anticipate all important resonant frequencies. We simulated the electromagnetic vibration behavior of the rotor using experimental modal analysis and finite element method analysis. The results obtained are applicable to alternator design for reduction.

    本研究では、「広域な移動」と「重力感覚の提示」を可能にする全身型力覚提示スーツを 提案し、本スーツをVR/AR空間に適用した時の視覚と力覚における人間の感覚や知覚の相互 作用の効果について明らかにする。
    2019年度は、下肢動作の重力知覚の基本的な動作解析と視覚と力覚情報の相互作用による提示効果の解明とその制御方式の確立について検討した。特に装着型でユーザが靴のように装着することができ,水中や泥寧の上の歩行感覚,また落下感覚を提示可能な装置の開発を目指す. 本年度では,装置開発の第一段階として落下感覚提示のために必要となる人間の落下感覚の評価をおこなった.
    現実空間での落下感覚と同様の落下感覚を仮想空間で実現するには,装置で提示する降下加速度,降下速度,降下高さ等の条件を現実空間での条件と一致させるのが望ましい.しか
    し,その条件を満たすためには,装置の巨大化に加え,ユーザの危険も増すため,ユーザが装着し仮想体験をする装置には適さない.そこで,著者らは,現実空間での降下加速度,降下
    速度,降下高さ等の条件と装置で提示する降下加速度,降下速度,降下高さ等の条件が異なる条件下でもユーザの落下感覚覚を満足させる装置の開発を目指す.

    蠕動運動は構造的柔軟性が高いゆえに「外部環境や外部刺激の変化に影響を受けやすいソフトロ ボット機構」である.本研究では蠕動運動型駆動システムに対して,外部環境の変化に柔軟に適応 できる制御系設計の確立を目的とする.特に本申請では,大腸の柔らかい運動機能を規範とした「蠕 動運動型ポンプ」に着目し,高粘度・固液流体の連続的な混合・搬送プロセスに生物的創発性の高 い制御系を適用する. 生物の独特の動きである蠕動運動は「柔軟駆動」「非骨格機構」「分散制御系」であり,ソフトロ ボット学のキーテクノロジーとして注目を浴びている.実際の生体大腸の運動は「第2の脳」と称 されるほど多数の神経ネットワークを駆使して効率よく駆動しているが,その詳細な仕組みについ てはわかっていないことも多い.そこで本蠕動ポンプにおいてもこれらの複雑なパラメータと 被搬送流体の流動との相関関係が,自律分散制御やAI系の深層学習等の生物学的創発性の高い制 御法の適用により明らかになれば,理学的興味として「生体大腸の蠕動運動による搬送・混合プロ セスの解明」,工学的興味として「蠕動ポンプの柔らかい運動に適した,さらなる効率的な搬送・ 混合手法の確立」につながると考えた.
    本申請では特に「環境からの外的刺激を分散的にセンシングする方式の確立」「自律分散制御や深層学習を用いた生物学的創発性の高い制御法の適用」について検討する
    2019年度は、特に「蠕動ポンプの柔らかい運動に適した,さらなる効率的な搬送・ 混合手法の確立」について検討する。
