Revolutionizing Prosthetics
Abstract
Brain activity was recorded with microelectrode arrays permanently implanted in the cerebral cortices of rhesus monkeys, The recorded activity was extracted in real time and used to control an anthropomorphic robotic arm. In the initial task, the monkey used this arm to reach out and grasp a piece of food and return it to its mouth by operating a simple gripper at the end of the arm. More recently another monkey is operating the arm in a doorknob task with the goal of reaching, grasping, twisting and pulling. The arm is now outfitted with a 4DOFarm, a 3DOF wrist and a 4DOF hand. We have developed algorithms to extract wrist orientation, trained the subject to perform hand orientation using brain control and the newly-installed wrist and demonstrated this in the task.
