Apparently the new i-limb system from Touch Bionics may need to be "scaled back" to be used by humans. The system is a robotic hand-arm combination for people missing all or part of their arms. One of its inventors admitted, "The i-Limb system is better than a human arm. It is faster and can lift heavier weights than a human arm . . . A patient would have the potential to hurt themselves or other people with it, as it is actually better than a human arm. It could do damage." Oh hai, sign me up! [Medgadget]
