![]() ![]() This paper introduces a new type of LWR with torque sensing in each joint and describes a consistent approach for using these sensors for manipulation in human environments. The LWR technology was transferred to KUKA Roboter GmbH, which will bring the first arms on the market in the near future. The described functionalities are of course highly relevant also for the potentially huge market of service robotics. ![]() Potential industrial application fields are the fast automatic assembly as well as manufacturing activities done in cooperation with humans (industrial robot assistant). Space and medical robotics are further areas for which these robots were designed and hopefully will be applied within the next years. The DLR robots are excellent research platforms for experimentation of advanced robotics algorithms. In order to act in unstructured environments and interact with humans, the robots have design features and control/software functionalities which distinguish them from classical robots, such as: load‐to‐weight ratio of 1:1, torque sensing in the joints, active vibration damping, sensitive collision detection, compliant control on joint and Cartesian level. In the DLR root concept, joint torque sensing plays a central role. Robustness is achieved in this context through sensor redundancy and passivity‐based control. Owing to the partially unknown properties of the environment, robustness of planning and control with respect to environmental variations is crucial. ![]() The paper seeks to present a new generation of torque‐controlled light‐weight robots (LWR) developed at the Institute of Robotics and Mechatronics of the German Aerospace Center.Īn integrated mechatronic design approach for LWR is presented. ![]()
