Waist-assistive exoskeleton powered by a singular actuation mechanism for prevention of back-injury

In order to evaluate the waist assistance provided by the developed robot, activation signals of electromyography (EMG) on main muscles of working wearers related to waist motions were measured. Further, the usability was evaluated using the responses of a questionnaire survey. Thus, the proposed method for waist assistance by a singular actuator is verified to be conclusively effective.
