Increasing Safety in Human-Robot Collaboration by Using Anthropomorphic Speed Profiles of Robot Movements
The demand for flexible production systems in which the flexibility at assembly processes is increased by human-robot collaboration rises. In such systems the safety of the worker, transparency of the robot’s actions and mental effort are of special importance. As acceptance of technical systems can be increased by anthropomorphism, an anthropomorphic speed profile of a simulated gantry robot is compared to conventional robotic trajectories. Results of a study with 20 male participants, in which the influence of these speed profiles for movements of the gantry robot on mental effort and prediction time was investigated, are presented in this paper. The results show a significant increase of accuracy for predicting target positions for the movements with an anthropomorphic speed profile. The speed profile does not have a significant effect on prediction times and mental effort. Hence, design recommendations for an ergonomic design of human-robot collaboration can be derived from these results.
