The system design uses preliminary works of the institute, namely the DLR Light Weight Robot III (LWR III) and the DLR Hand II. The torso based on LWR technology and the mobile platform enlarge the workspace of the arms and hands. The overall design resembles a human-like shape. The upper body holds a total of 43 controllable degrees of freedom, equipped with link side torque sensors which enable the impressively sensitive manipulation capabilities.
Actuated degrees of freedom:
