The Analysis and Control of Exoskeleton Upper-Limb Rehabilitation Robot

Abstract

Based on the analysis of the methods for upper limb rehabilitation training, an anthropomorphic upper-limb exoskeleton was developed. Anatomical and physiological characteristics and upper limb joint ranges of motion are also considered. The rehabilitation robot is achieved by 4 single-axis revolute joints which are shoulder abduction-adduction (abd-add), shoulder flexion-extension (flx-ext), elbow flx-ext and wrist flx-ext. Kinematics and dynamics analysis of the rehabilitation robot are made. The passive rehabilitation mode and active rehabilitation mode are researched, and the result of experenment is shown that the robot can finish the rehabilitation task well.
