Development of Power Assist Wear Using Pneumatic Rubber Artificial Muscles

et al. 2016

Abstract.Recently, the rehabilitation device using a soft pneumatic actuator for disabled are actively researched and developed because of the insufficient number of PT. In the previous study, the wrist rehabilitation device using flexible robot arm that consisted of three flexible pneumatic cylinders was proposed and tested. In this study, the wearable wrist rehabilitation device is proposed and tested. The attitude control based on the analytical model of the devise is also carried out. As a result, it is confirmed that the device can trace the desired position in the condition when a human wears the device.

Development of Wearable Wrist Rehabilitation Device Using Flexible Pneumatic Cylinders

Kato

et al. 2016

“…According to aging society and decreasing birth rate in Japan [1], the requirement using soft actuator for the rehabilitation device and power assisting devices is rapidly increasing [2][3][4][5]. As a soft actuator, a rubber artificial muscle is well-known and actively used because of its larger generated force.…”

Preliminary Design of Flexible Linear Stepping Actuator Driven by Pneumatic Balloons and Brakes

Eguchi

2016

Abstract. Recently, the requirement for development of soft actuator for the rehabilitation device and power assisting devices is increasing. However, development of a flexible actuator that has both larger force and longer stroke has not been carried out. In addition, it is also difficult to realize a flexible displacement sensor with long stroke while deforming its form according to the actuator's shape. In this paper, development of the flexible actuator with larger force and longer stroke that can adjust its stroke by giving stepping motion using pneumatic balloons and brakes is described. The fundamental performance of tested actuator is also investigated.

“…Recently, pneumatic welfare systems to support a nursing care and a rehabilitation of the elderly and the disabled are actively researched and developed [1][2][3][4]. In the system, many wearable actuators such as a rubber artificial muscle have been used [5][6][7].…”

Development of Compact Flexible Displacement Sensors Using Ultrasonic Sensor for Wearable Actuators

Morimoto

et al. 2016

Abstract. In position control of wearable actuator such as a rubber artificial muscle, a compact flexible displacement sensor is much attractive and required. In this paper, two types of flexible displacement sensor using the ultrasonic sensor were introduced. One is a built-in displacement sensor for rubber artificial muscle. Another is a sensor that can measure the sliding displacement on a flexible tube for flexible robot. Both sensors use ultrasonic displacement sensors. The construction, operating principle and measuring performance of two sensors were also described.
