We've had our eyes on Argo Medical Technologies' ReWalk for a couple years, ever since the exoskeleton walked into view with a gait (and a sound) eerily reminiscent of RoboCop's. The device weighs seven pounds and features two leg braces with motorized joints and motion sensors, a harness, and a backpack for holding the computer that controls the device and a battery that should last a good three-and-a-half hours. In addition to giving paraplegics the ability to walk, this bad boy can be used to treat the health complications of those who cannot walk on their own, including digestive, cardiovascular, and circulatory issues. After clinical trials in the US and Israel, the device is due to go on sale to rehab centers worldwide this January. The cost for one will be in the $100,000 mark.
