Here is an exoskeleton designed to take load off soldiers. Lockheed Martin’s ONYX Exoskeleton is a powered lower-body device that increases mobility and reduces fatigue. ONYX conforms to the human body and has sensors that read speed, direction, and angle of movement to an on-board computer that drive electro-mechanical actuators at the knees.
ONYX reduces the energy needed to squat, kneel, and move. It simply reduces stress on leg muscles and increases ability to handle rough terrain and stairs.
