It is not uncommon for someone to wish that they had an extra set of arms or a pair of helping hands, that is exactly what the Supernumerary Robotic Limbs grant. No need for a genie in a bottle or a class at Hogwarts School of Witchcraft and Wizardry, instead a chummy relationship with someone at the MIT d’Arbeloff Laboratory is all that is needed. Granted, the Supernumerary Robotic Limbs were created with a specific profession mind.
Made to assist users in performing manipulation tasks in an aircraft manufacturing setting, the Supernumerary Robotic Limbs are strapped onto the wearer's back. They can either come over the shoulders or extend from around the waist. Working with a system of gyros and accelerometers attached to wrists, the robotic limbs are capable o detecting where the user's real arms will move. This allows them to anticipate any needs.
