In the future, service robots will need mobility, light-weight yet powerful arms and articulated hands. We are convinced that DLR Hand II – even better in combination with DLR’s light weight arm developments – is an important contribution to reach these goals.
Indeed this new robot hand fulfills these requirements. Together with the DLR Light-Weight Robot, the DLR Hand II is perfectly suited for mobile service applications.
The DLR Hand II is an anthropomorphic dexterous grasping and manipulation system. The hand consists of four identical fingers with four joints and three degrees of freedom each. An additional degree of freedom in the palm allows the hand to adjust perfectly for either stable grasping or fine manipulation.
Complete integration of the actuation system, the sensors and the communication electronics in the hand leads to maximum flexibility and allows easy interfacing to different robots.
Numerous sensors allow the precise control of the hand parallel to a very sensitive feed-back of forces and finger positions. This is the prerequisite for dexterous telemanipulation.
Similar to a human acting with her hands, very different a priori unknown objects have to be grasped and manipulated and various tasks have to be accomplished in an unknown environment. Examples are opening and closing doors and drawers, operating devices, and using tools. The human hand is the template for the design of the anthropomorphic DLR robot hand which is a universal dexterous grasping and manipulation tool for service robotics.
