Safe Human-Robot Cooperation with High Payload Robots
Safe Human-Robot Cooperation with High Payload Robots in Industrial Applications (SAPARO)
In the SAPARO experiment we propose an innovative and trendsetting solution for safeguarding collaborative human-robot workplaces with high payload robots through a combination of safeguarding technologies addressing both hard- and soft- safety considerations. This consists of a tactile floor with spatial resolution as a hard-safety sensor for workspace monitoring together with a projection system as a soft-safety component to visualize the boundaries of the safety zones. We further develop and implement algorithms and software to dynamically define the safety zones around the robot depending on its actual movements (not static, pre-defined safety zones), which will be safeguarded by the tactile floor and visualized for the worker by the projection system. The safety zone will be generated online according to the relevant guidelines in EN ISO 13855 and will be based on the current robot’s joint angles and velocities any time. Feasibility and constraints according to the relevant safety standards EN ISO 10218-1 and -2 and EN ISO 13855 will be demonstrated.
