Product description according to them: "ONYX conforms to the human body. Sensors distributed on the exoskeleton report speed, direction, and angle of movement to an on-board computer that drives electro-mechanical actuators at the knees. The exoskeleton delivers the right torque at the right time to assist knee flexion and extension. ONYX ultimately reduces the energy needed to cross terrain, squat, or kneel. These benefits are most noticeable when ascending or descending stairs or navigating inclined surfaces."
