The new bebionic3 myoelectric hand, which is also made from aluminium and alloy knuckles, moves like a real human limb by responding to Nigel's muscle twitches. Incredibly, the robotic arm is so sensitive it means the father-of-one can touch type on a computer keyboard, peel vegetables, and even dress himself for the first time in six years.
