Prototype of Auxiliary Device for Upper Limb Lifting Work Using Linkage Mechanism

Abstract

The purpose of this study is to develop a lighter and smaller auxiliary device that can assist the user’s arm to reduce burden on workers. The auxiliary device consists of a mounting part and a linkage mechanism in order to use a passive gravity compensation mechanism. In this paper, we used a spring without power supply. The spring is used to adjust the posture of the arm part. The effectiveness of the proposed auxiliary device is verified by the result of the experiments.
