Meet the MechaHand: a robotic arm that can mimic your hand movement. It is driven by an ATmega2560 microcontroller. The wrist joint rotates from 0 to 180 degrees. The hand has 3 finger joints and can pick/hold objects and perform a variety of tasks.
According to the developers, these robotic arms are much cheaper to make than beBionic, i-Limb, and other advanced prosthetic arms.
