Title:
SELF-TRAVELING AUTOMATIC TRACKING DEVICE, WHITE LINE DRAWING DEVICE, AND WHITE LINE REMOVING DEVICE
Document Type and Number:
Japanese Patent JPH0417005
Kind Code:
A
Abstract:
PURPOSE:To draw an accurate white line without human intervention by controlling the position of a running device by means of a steering controlling section on the basis of the output signal of a guide sensor to make the running device to run along guide markers. CONSTITUTION:A running device is provided with a guide sensor 1 which detects guide markers 11 buried in the ground and a steering controlling section 5 which controls the steering of the device so that the device can run along the markers 11 and the sensor 1 outputs the deviation and deviated direction of the device from the markers 11 as a voltage value with code. The section 5 outputs a steering controlling signal by using the output of the sensor 1 signal in the direction in which the deviation can be corrected. Therefore, the running device can run without deviation form the markers 11 and a highly accurate white line can be drawn without human intervention.
