PURPOSE:To merely latch driving data at the time of receiving, to make a receiving circuit simple and to prevent an influence of the noise by receiving in the digital data form. CONSTITUTION:Head and driving data, which are received and inputted through an antenna 11, a high frequency amplifier 12 and a demodulating circuit 13 after a synchronizing signal, are shifted and inputted to a six-bit register 15. Out of these, lower rank four-bit driving data are in parallel taken in and latched when a 1/6 dividing signal is impressed to a latch circuit 21. The driving data is inputted to a voltage supply part 24 composed of a decoder 22 and a power source selecting circuit 23, and driving voltage in accordance with the driving data is supplied to a left driving motor 25L which drives positively and negatively the wheel at the left side and a right driving motor 25R which drives positively and negatively the wheel at the right side, and a travelling drive is executed. |
