Abstract
This study presents a smart arm exoskeleton roboticdevice that designed to perform the physical therapy for disabled patients in order to rehabilitate the affected limb. The basic principle of this exoskeleton is its dependence on electromyography signal; MyoWare sensor was used to measure surface electromyography signal. Surface electrodes were used between skin and MyoWare to pick up the signal from biceps brachii muscle. The microcontroller processes the signal of muscle activity and outputs a voltage to control the direction of a motor. The motor moves the actuator arm through Bowden cable. The exoskeleton robot is one degree of freedom performs the flexion and extension of the elbow joint. After the design was completed, it was tested according to some parameters to check its efficiency. The resultsindicated the feasibility of this exoskeleton to move according to muscle’s signal and to tolerate the human arm’s weight whatever the human weight.
