Abstract
In this research, we developed a wearable power assist system Smart Suit for snow shoveling, and constructed Motion Based Assist Method. The Smart Suit is controlled by semi-active assist system with elastic materials and adjustable assist mechanisms. Motion Based Assist Method is an technique to design control rule by measuring the motion. We propose the control rule that used joint angle and joint angular velocity, and performed an experiment to verify its assist effect. As a result of experiment, it was effective especially to the legs. It was confirmed that about 20% physical load were reduced on average.
