No, the Shadow Robot Hand is not a futuristic martial arts stance, but is an actual robot hand that boasts a pretty dextrous disposition, enabling it to perform previously unimaginable feats (for a robot at least) such as picking up small coins from the floor and holding a tomato gently. This high level of dexterity is achieved by using compressed air in 36 of its 'muscles'. These air reservoirs are refilled by a foot pump. Currently, the Shadow Robot Hand's limitation depends on the creativity of the programmer who codes under GPL. No idea on how much it costs, but you can be sure it ain't gonna be cheap.
