Development and evaluation of muscle suit for arms and lower back support

We have been developing the wearable muscle suit for direct and physical motion supports. The use of the McKibben artificial muscle has opened the way to the introduction of “muscle suit” compact, lightweight, reliable, wearable “assist-bots” enabling manual worker to lift and carry weights. Muscle suit for lower back assistance is already commercially available though, arm assist is also important. In this paper, we present the arm assist muscle suit in addition to back assistance and evaluation results will be shown.
