Hand Arm System

Details

The Hand Arm System is designed to have the size, strength, and speed of a human arm. It uses superstrong cables as tendons, and its aluminum endoskeleton makes it look like the Terminator's hand.

HISTORY
The Hand Arm System is the culmination of decades of research in robot manipulation by researchers at the DLR Robotics and Mechatronics Center. The main motivation for the project is the fact that when robots perform tasks in the real world, they inevitably collide with objects, the environment, and even people. For that reason, the DLR researchers believe that future robots have to be able to handle collisions without suffering or causing damage. The DLR Hand Arm System uses elastic components capable of storing energy and actuators capable of changing their stiffness to achieve the robustness needed against collisions. The Hand Arm System is currently used as a platform for advancing dexterous manipulation and for exploring new applications in robotics.
