Need a hand? Mind-controlled robotic arm lets you do two things at once

If you've ever wished for an extra arm to carry out a complex task, researchers may have the answer. Researchers in Japan have taught volunteers to use a mind controlled robotic arm to help them out in doing two things at once. They say the system could revolutionise factory and construction work. Researchers in Japan have taught volunteers to use a mind controlled robotic arm to help them out in doing two things at once. Engineers from Kyoto's Advanced Telecommunications Research Institute showed some people can be taught to control a third robotic arm with their brains, even using the limb to multitask.
