Video of ReWalk Exoskeleton System
Argo Medical Technologies' ReWalk exoskeleton system allows people with paralyzed legs to walk.
ReWalk comprises a light wearable brace support suit with DC motors at the joints, rechargeable batteries, an array of sensors and a computer-based control system. It fits the body snugly to detect upper body movements, which are used to initiate and maintain the walking process.
