PURPOSE:To provide a self-propelling vehicle operated by radio, which runs before a player as a pacemaker during athletic sports and training and arousing player's will. CONSTITUTION:A coach 27 pays attention in front of a self-propelling vehicle 1, avoids a obstacle of a road and operates the self-propelling vehicle 1 with a remote control box 19. At the same time, the running speed of the self-propelling vehicle 1 is adjusted in consideration of the athletic strengthening of a runner 26 at the same time. In the self-propelling vehicle 1, whose running speed is determined by the specified program, it is not necessary that the coach 27 gives the command for the speed, but the coach only gives the command of the running direction. A guide line is embedded under the course in a track of an athletic field. With the line as an antenna, the guidance and the speed of the self-propelling vehicle 1 are instructed. When the runner 26 keeps the constant interval from the self-propelling vehicle 1 all the time and follows the vehicle to the last, the runner 26 can renew his own record. |
