PURPOSE:To obtain a running control device based on human cerebrum and eyes without a computer and a sensor by running a carrier with driving torque in proportion to the stroke in correspondence with the pulling or pushing of a manual piece, and changing the direction of wheels in proportion to the rotating angle when a long lever is turned to the right and left. CONSTITUTION:When a long lever is turned in the clockwise direction the voltage of 35a becomes larger than that of 35b. The output voltage of an operation amplifier 31a is increased accordingly. The voltage is inputted into a conduction control circuit 34 of a motor 8a through a diode 32a and a chopper circuit 33a. Thus, the motor current is increased, and a motor is operated in the forward direction. Thus, the direction of wheels is changed. A carrier can be moved back and forth by the pulling or pushing of a manual piece. When the a manual piece is pulled in the advancing direction, a soft ferrite rod is moved, and the output voltage of a coil 24a is increased to the value larger than the voltage of a coil 24b. Therefore, the motor is rotated in the forward direction and drives the wheels, and the carrier advances. When the coils 24, 24a and 24b and the ferrite rod reach the neutral point, the armature current of the motor becomes zero, and the motor is stopped. |
