The invention relates to a method for simulating a movement range of a robot (10) with a data processing system and an control module which allows a movement path of the robot (10) to be simulated. In said method, one respective stopping distance (30) is calculated for a number of selected points in the movement path by means of a safety control module. A virtual movement range which includes the maximum range of the robot is defined taking into account the stopping distances (30). The invention also relates to a system for carrying out said method.
