Oscar Constanza has a genetic neurological condition that has left him wheelchair-bound, but his father, a robotics engineer, created something to help. Jean-Louis Constanza is co-founder of Wandercraft, a company in France that developed an exoskeleton to help disabled people walk, stand and sit. It’s an outer frame that supports and simulates body movement and the company is working on a much lighter version that can be bought and used by people.
