Abstract: An acquisition section 42 acquires a pose at a clock time ti and a pose at a clock time tj for each of plural robots, and acquires structural information. Based on structural information a computation section 44 computes positions of the prescribed part for each of the robots at the clock times ti, tj and at a midway clock times tc. A possibility determination section determines a possibility of interference, based on any overlap between added-margin regions resulting from addition of a prescribed margin to a circumscribing shape containing positions of the prescribed part at the clock times ti, tj, and tc for each of the robots. In cases in which there is a possibility of interference, an end determination section 48 sets tc so as to be a new ti or a new tj, and causes processing of the computation section 44 and the possibility determination section 46 to be executed repeatedly until a spacing between the prescribed parts satisfies an end condition.
