Kollisionsfolgenabschätzung bei der Mensch-Roboter-Kooperation mit einem Seitenaufprall Dummy

S. Oberer, C. Meyer (Fraunhofer-Institut IPA) To prepare new generations of robot systems for direct human-robot-cooperation new design criteria have to be set up, not only focussing on process specific characteristics but as well on a minimum hazard potential. In case of any failure only negligible injuries can result for a human. Robot cells that do not facilitate a complete separation of the human from the operating space of the robot will ever retain the risk of a collision in free space especially when contact between the user and the robot is the substantial feature of the cooperation. Scenarios with an industrial robot and a side impact dummy are set up to analyse the dummy characteristics during different collision configurations to enable a classification of the hazard. By means of LS-DYNA simulations and an experimental measurement setup these impacts are evaluated. Potentials and limitations are then discussed how these crashworthiness study can be used to draw conclusions for the assessment of the passive safety of a robot.
