2P1-C03 Evaluation of Trunk Stabilization Effect by Tightening Force Generated by Smart Suit Lite(Welfare Robotics and Mechatronics(3))

Abstract

A passive power-assist supporter called Smart Suit Lite, which is a compact and lightweight power-assist device that utilizes the restoring force of elastic belts, has been developed. The design method to optimize the Smart Suit Lite for particular motions has been constructed. It uses the musculoskeletal dynamics simulator and an extended musculoskeletal model which has skin segments for analyzing assist force. In this paper, two basic experiments were performed to evaluate the postural stabilities for constructing a mechanical model of the trunk stabilization effect of the Smart Suit Lite. As a result of the experiments, it is confirmed that the standard deviation of the lumbar angle decreased by 32.1% on average in wearers with low stability.
