Space station motors make a robotic prosthetic leg more comfortable, extend battery life – Tech Xplore

A new robotic prosthetic leg prototype offers a more natural gait while also being quieter and more energy efficient than other designs.
The key is the use of new small and powerful motors, originally designed for a robotic arm on the International Space Station. The streamlined design offers a free-swinging knee and regenerative braking, which charges the battery with energy captured when the foot hits the ground. This feature enables the leg to more than double a typical prosthetic user’s wal…
