The purpose of this study is to build a control system for a wearable power assisting device, which helps people with lifting heavy things, like a person who can’t move alone in daily life. When we lift something heavy, we use both hands. That’s why a control system that can automatically switch on/off without using hands is necessary. In this study, we analyze human lifting up motion, and reveal characteristics of the motion, to find the suitable timing for switching the wearable power assisting device. Results show that the automatic switching can be realized.
