PROBLEM TO BE SOLVED: To provide a moving body which can move keeping a file when moving in forming a file with a plurality of the moving bodies and can change a speed in the movement without disturbing the formation. SOLUTION: The moving body receives orbit data which designate a time and its position at that time as time goes on, and stores the data. The moving body moves so that it may be located at a position in which the orbit data designate at a time which the orbit data designate. When the moving body acknowledges speed change instructions, it corrects the time data of the orbit data stored and moves so that it may be located at the position designated at the time thus corrected. Each moving body moves to the position designated at the same time even if the speed is changed, and accordingly the file is not disturbed. COPYRIGHT: (C)2005,JPO&NCIPI
