A hip exoskeleton was designed that can assist hip flexion and extension. The device incorporates a motor, ball-screw, and spring in a lightweight package. The total weight including the battery is 2.95 kg. The system uses 20 W of power per leg. The system is controlled based on the phase angle of each leg and the torque is applied in synchrony with the user’s steps. The device assists walking, running, and does not interfere when going up and down stairs.
