Abstract
An apparatus for guiding the traveling of a moving body along a predetermined traveling path with a high degree of accuracy by accurately and reliably determining a corrected position and a corrected traveling direction of the moving body. A moving distance of the moving body between points of reception of light beams is obtained by a counter, and a CPU calculates a corrected position of the moving body by using an angle formed by the projecting directions of the light beams, the position of installation of a reflecting mirror, and an estimated traveling direction obtained on the basis of an output of a rate gyro. A corrected traveling direction is then calculated by using the corrected position thus calculated. The corrected position is calculated by using the traveling direction thus estimatively calculated. Since it is not necessary to directly determine the traveling direction, only two sets of devices for projecting and receiving the light beams are required, and only one device for reflecting the light is required, thereby improving the reliability of the apparatus.
