Safety in Human-Robot Interaction

DLR is highly engaged in the evaluation of “safety in Human-Robot Interaction” within several European projects (SMErobot, PHRIENDS).
  • Scenario: The DLR Lightweight Robot III was developed with strong emphasis on direct Human-Robot Interaction. It is equipped with sensitive joint torque sensing in each joint in order to realize direct physical interaction. The new KUKA Lightweight robot is the result of a technology transfer from DLR to the robot manufacturer KUKA Roboter GmbH. In order to present our overall concept for “safety in Human-Robot Interaction” a Co-Worker scenario was developed and evaluated.
  • Crash Tests: Standardized crash tests for assessing human injury during collisions with the Lightweight Robot show the origins of our work for a classification and evaluation of injury in human-robot interaction.
  • Collision Detection and Reaction: The integrated position and torque sensors of the Lightweight robot allow fast and sensitive collision detection and reaction. This gives the robot even the ability to prevent injuries with sharp tools.
  • “Feel the safety”: User interaction is an integral part of this exhibit, giving the visitor a hands-on experience of the collision detection and reaction mechanisms.
