Development of rotary actuator for power assist suit

Abstract

In order to realize a power assisting suit for assisting a nurse caring a patient in her arm, a new actuator using Bellows have been developed. The power assisting suit consists of shoulders, arms waist and legs made of aluminum, and is fitted on the nurse body. The power assisting suit was originated with the concept of a master and slave system in one body. This paper gives the characteristics of Bellows pressure, compliance, and circuit clear for the purpose of developing how to control an actuator.
