ABSTRACT:
An automatic guided vehicle comprising a loading table provided with positioning motors for three directions including two on a horizontal plane and a rotational one around a vertical axis and also with optical sensors for detecting positioning marks at stop positions so that positioning of the automatic guided vehicle at a stop point thereof may be ensured in high precision, and a method for positioning the automatic guided vehicle without attendant with high precision in such manner that the optical sensors detect degrees of deviation between the guided vehicle and the positioning marks, and positioning motors are driven after computing three-directional positioning correction values based on the result of detection or reducing deviation at the loading table.
