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...
A desktop force feedback device is able to render reaction force of virtual objects. However, the desktop type limits operator's motion. 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,...
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,...
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...
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...
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,...
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...
