If you need a Third hand to help you, think of this Third Arm. This concept by Stelarc.He is the same Australian performance artist who hung himself naked from flesh-piercing hooks attached to ropes.
The artificial hand, attached to the right arm as an addition rather than as a prosthetic replacement, is capable of independent motion, being activated by the EMG signals of the abdominal and leg muscles. It has a pinch-release, grasp-release, 290 degree wrist rotation ( clockwise and anti-clockwise ) and a tactile feedback system for a rudimentary "sense of touch".
Whilst the body activates its extra manipulator, the real left arm is remote-controlled / jerked into action by two muscle stimulators. Electrodes positioned on the flexor muscles and biceps curl the fingers inwards, bend the wrist and thrust the arm upwards. |
