Development of the heavy load transferring task oriented exoskeleton adapted by lower extremity using qausi - Active joints

Abstract

Herein, this study proposes that the exoskeleton has not full of active DOF (Degree of Freedom) joint, but partial active DOF joint which is so called the quasi-active joint system. It consists of 4 quasi-active joints and 2 active joints 3 passive joint and 1 active joint. So as to verify the efficiency of the quasi-active exoskeleton, muscle activation results are compared by before and after the wearing exoskeleton results.
