What means Exoskeleton?
An exoskeleton is a wearable robot attached to the human
body to influence or assist human motion.

• Motion assistance for patients in rehab.
• Muscular enhancement of industrial workers or soldiers .

• Active engine to provide torque/force for joints.
• Passive stiffness to support/limit body motion.
