PROBLEM TO BE SOLVED: To move a mobile device along a curve in a predetermined direction by remote control from a fixed position by installing a device for refracting an optical signal and then transmitting it to the mobile device and adding the information for identifying each device to the optical signal. SOLUTION: When an optical signal, which includes control information and identification information indicating the sender of the signal from a transmitter and receiver 1 to an A relay 3, the optical signal is refracted by the A relay 3 and then is transmitted to the mobile device 2. Consequently, the movement of the mobile device 2 is controlled, based on the information included in the optical signal transmitted from the transmitter and receiver 1. Likewise, when an optical signal, which includes control information and identification information, is transmitted from the transmitter and receiver 1 to the A relay 3; then an optical signal including control information and identification information for specifying a B relay 4 is transmitted from the A relay 3 to the B relay 4; and an optical signal including control information is transmitted from the B relay 4 to a mobile device 2'. Consequently, the movement of the mobile device 2' is controlled, based on the control information included in the optical signal transmitted from the transmitter and receiver 1. |
