Workload-sharing robotic limbs by MIT

MIT engineers are designing a limb which will help people to hold objects, share a workload, and streamline the execution of a task. For example situations might include trying to open a door when you need to keep holding something with both hands. If the movements of such supernumerary limbs are tightly coupled and coordinated with their arms, the human users may come to perceive the extra limbs as an extension of their own body.
