LOWER ARM = FOREARM + HAND

The Lower Arm is composed of 12 motors (Forearm: 10 + Hand: 2)

Let's describe the functionality of those motors:

Forearm: (10)

Pronosupination (1)

Wrist: (2) = pan + tilt

Thumb: (2) = proximal + distal

Index: (2) = proximal + distal

Middle: (2) = proximal + distal

Pinky-ring fingers: (1) = distal

Hand: (2)

Fingers abduction (1)

Thumb oppose (1)
