Toyota unveils robotic leg that lets paralysed people walk

Toyota is introducing an Iron Man-style robotic leg brace designed to help partially-paralysed people walk. The Welwalk WW-1000 system is made up of a motorized mechanical frame that fits on a person's leg from the knee down. The robot assistant could help older people left partially paralysed after a stroke, Toyota claims. The patients can practice walking wearing the robotic device on a special treadmill that can support their weight. Toyota demonstrated the equipment at its Tokyo headquarters on Wednesday. One hundred such systems will be rented to medical facilities in Japan later this year, Toyota said.
