Hand With Air Muscles
The Shadow Robot Company's take on the robotic hand, introduced in 2007, draws its power and dexterity from compressed air. Forty "muscles" made of rubber tubing are attached to various points on the metal hand through internal wires. As the tubes are inflated and deflated, the portions of the hand they're attached to move. The hand's many muscles, combined with its finger-like joints, let it move with great dexterity.
This robotic hand can also be outfitted with touch sensors, allowing it to perform delicate tasks like screwing in a light bulb, picking up a raw egg and wiggling it around, andin a particularly memorable bit of videogiving someone a scalp massage.
