An assistive device is developed to help the peoples with disability to have a self-supporting life. This device uses two motors to lift up the user's arm and to bend the elbow joint. The force can be easily adjusted by the electric motor control. The control mode can be selected based on the user's ability. An original human interface to use a muscle activity sensor is introduced to enable the human friendly operation of the assistive device.
