Most of the robotic limbs you hear about are meant to replace arms and legs that have been lost to injury, but MIT is working on robotic limbs that are just meant to add on additional ones, giving people three or four arms so that they can get more done. Its researchers demonstrated the limbs — which they call supernumerary robotic arms — at a conference yesterday in China, and videos show that they’re already working to a basic extent. The current suit reportedly weighs just 10 pounds, but right now it seems to mainly be useful for holding light objects in place.
“Once we combine the most significant behavioral modes we are able to control the robot such that, from the wearer’s perspective, it behaves like an extension of his own body,” Baldin Llorens-Bonilla, an MIT researcher working on robotic limbs, tells IEEE Spectrum.
