Abstract
The disclosure relates to a method for operating a robot as well as to a correspondingly operated robotic system. As part of the method, it is determined, if a difference between a current position of the robot and a target position of the robot exceeds a predetermined threshold value while the robot is in a torque-regulated operating mode. If the difference exceeds the threshold value, a predicted model-based intermediate state that the robot reaches before the target position according to the model is determined, wherein a speed of the robot in the intermediate state is lower than a predetermined speed threshold. When the robot reaches the intermediate state, the robot is automatically switched from the torque-regulated operating mode to a position-regulated operating mode. The robot then moves into the target position in the position-regulated operating mode.
