Loosely modeled after the human arm, this pneumatic Lego version has three fingers, a flexible/rotatable wrist, and a custom built control unit (battery pack and compressors). Three video clips after the jump.
The shape of the hand adapts itself to the object grabbed. Piston linear motion is converted to a rotation one by a lever, gears and a universal joint transmit motion to the wrist turntable.
