Abstract
The effect of change in impedance parameters of an electromyography (EMG) based impedance controller for a 7DOF upper-limb power-assist exoskeleton robot, which assists daily upper-limb motions of elderly or physically weak individuals were analyzed. The experimental results show that the impedance parameters of the EMG-based impedance controller should be changed according to the upper-limb posture and the amount of the EMG signals.
