From the Beeb: Robo-skeleton lets paralysed walk.
A robotic suit is helping people paralysed from the waist down do what was previously considered impossible – stand, walk and climb stairs.
ReWalk users wear a backpack device and braces on their legs and select the activity they want from a remote control wrist band.
Leaning forwards activates body sensors setting the robotic legs in motion.
Users walk with crutches, controlling the suit through changes in centre of gravity and upper body movements.
The device effectively mimics the exoskeletion of a crab. [continue, see photos and video]
