Shadow hand

The Shadow Hand is an advanced humanoid robot hand system that reproduces as closely as possible the 24 degrees-of-freedom of the human hand. It has been designed to provide comparable force output and movement sensitivity to the human hand. All design measurements were taken directly from the corresponding body parts of the engineering team.

C5 Shadow dexterous hand

The Shadow Dextrous Hand is a self-contained system. The forearm region contains the muscles and the valve manifold. The Shadow Dextrous Hand system incorporates all necessary control systems (software provided under GNU GPL) and documentation for research and teaching purposes. The Hand has been designed to be as similar as possible to the average hand of the human male.

The forearm structure is comparable in length to the human forearm, although at the base it widens to 146mm.

Finger length from tip of finger to middle of knuckle 102mm

Thumb length 102mm

Palm length from middle knuckle to wrist axis 55mm

Palm thickness 22mm

Palm width 84mm

Thumb base thickness 34mm

Forearm base to wrist axis 434mm

The Hand, sensors, muscles and valve manifold have a combined weight of 3.9 kg. The centre of mass is approximately 160mm from the base. There is some variation in movement speeds between the parts of the Hand. Also, different methods of movement produce different maximum speeds. However, the general movement is on average about half the speed of that of a human. For example, the time for transition from open to clenched is 0.2 seconds approx.

The entire system is built with a combination of metals and plastics

- Forearm bone: Steel

- Palm: Acetyl, aluminium, polycarbonate

- Fingers: Acetyl, aluminium, polycarbonate fingernails and polyurethane flesh

- Base: Acetyl, rubber, brass, cork.
