The US Food and Drug Administration has recently approved the most revolutionary robotic device – the ReWalk. It will enable people confined to wheel chairs due to injuries in the spinal cord to walk again. This is the first ever exoskeleton that is completely robotic and approved for home use in the US. The device will aid walking by moving the lower limbs of the person wearing it.
The ReWalk is strapped on the person’s legs and also onto the upper body for support. There is a motor at every joint including the ankles, knees and hips that is entirely controlled by an internal computer. The leg sections are enforced by additional straps near the midsection which also connect with the backpack containing the power batteries and the internal computer.
The wireless remote controller is worn on the wrist. The user stills needs crutches to stabilize him, but this device has great promise for the future as more research will be carried out to make it the best of its kind.
