Scientists in the US have created a robotic arm that can be controlled by thought alone. Developed at the University of Pittsburgh, it has a fully mobile shoulder and elbow and a gripper that works like a hand. In early tests, monkeys had tiny probes inserted into their brains and had their limbs restrained - but were then able to manipulate the robotic arm. The inventors believe it could help people who have lost limb function. The mechanical arm research was described at the annual meeting of the American Association for the Advancement of Science held this year in Washington DC. via BBC.
