Toyota is introducing a wearable robotic leg brace designed to help partially paralyzed 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 patients can practice walking wearing the robotic device on a special treadmill that can support their weight. Toyota Motor Corp. demonstrated the equipment for reporters at its Tokyo headquarters recently. One hundred such systems will be rented to medical facilities in Japan later this year, Toyota said.
