Father builds exoskeleton to help wheelchair-bound son walk

PARIS - "Robot, stand up" - Oscar Constanza, 16, gives the order and slowly but surely a large frame strapped to his body lifts him up and he starts walking.

Fastened to his shoulders, chest, waist, knees and feet, the exoskeleton allows Oscar - who has a genetic neurological condition that means his nerves do not send enough signals to his legs - to walk across the room and turn around. "Before, I needed someone to help me walk ... this makes me feel independent," said Oscar, as his father Jean-Louis Constanza, one of the co-founders of the company that makes the exoskeleton, looks on.
