PURPOSE:To attain the control of a fixed degree to both working direction and working value even in case a visual operation is difficult, by adding a keyboard to a radio controller having a joy stick to have input of a shift command for input of coordinates. CONSTITUTION:Both working direction and working value are supplied to a keyboard 4 of a radio control panel 1 and a built-in ENT key is pushed for input of a shift command to an arithmetic part 5. This command undergoes the modulation of its pulse via the part 5 in the form of a command code in preference to the command of a joy stick 2 and is transmitted through an antenna 3 via a communication part 6. In this case, the signal received via an antenna 12 and a communication pat 13 is demodulated into a command code through an arithmetic part 14 of a radio control vehicle 11. Then the servo amplifier 15 and 16 are controlled for drive of motors 17 and 18 according to a shift instruction. Thus it is possible to have input of a shift distance and a shift angle in terms of coordinates with parallel use of a joy stick and a keyboard. Then the visual malfunctions can be eliminated and the control is possible with the working of a fixed degree.
