Design and evaluation of an upper extremity wearable robot with payload balancing for human augmentation

Abstract

Electric, pneumatic and hydraulic tools are widely used in industry. Repetitive tasks using heavy tools would often cause fatigue for workers leading to musculoskeletal injuries. The efficiency and manufacturing quality can hardly be guaranteed either. Powered exoskeletons for upper limb [1-3] and lower limb assistance [4-5] have been developed recently.
