Abstract: An automated method determines a safety zone for a robot. The robot carries out operations along a specified trajectory. For collision-free operation, a safety zone is determined by: dividing the specified trajectory into a plurality of subtrajectories; determining a plurality of fine-grained envelope cuboids around extreme points of each subtrajectory; and determining a number of optimized envelope cuboids from an enlargement of individual fine-grained envelope cuboids in relation to the volume occupied by the enlarged fine-grained envelope cuboids. The optimized envelope cuboids determined in this way form the safety zone for the trajectory. This automated method can be expanded to multiple trajectories of a robot, multiple robots, and replanning a trajectory for an occupied semaphore zone.

Abstract: A method for operating a programmable logic control device to which a current input data set having state data regarding a peripheral component is provided cyclically by a communications bus after each bus cycle terminates. A first program instance of a control program is cyclically processed by a control device. The program cycle duration is longer than the bus cycle duration and, therefore, between the beginning and end of the program cycle, the communications bus provides at least one current data set that cannot be taken into account by the first program instance. To reduce the latency with which a control device reacts to a change in the input value of a peripheral component. at least one other program instance of the control program is cyclically processed so that it is temporally offset by less than one program cycle duration relative to the first program instance.
