Abstract: A robot vehicle for automatic operation in a predetermined travelling route comprises a pair of driving wheels connected to a driving device; means for detecting revolving speeds of said driving wheels; means for detecting azimuth of the travelling direction of said robot vehicle; a memory device for memorizing a travelling program including data of a travelling distance and an azimuth; and a control processor device which control the travelling of said robot vehicle depending upon the travelling program of said memory device under comparing the travelling distance and azimuth of the travelling program with a travelling distance detected by said revolving speed detecting means and an azimuth detected by said azimuth detecting means.

Abstract: The present invention relates to an apparatus for controlling a moving object and particularly for automatically stopping the moving object in a predetermined position and direction. The apparatus comprises a pair of photoelectric sensors having a light emitting element and a light receiving element for the moving object, and a pair of reflectors at predetermined positions opposing the photoelectic sensors. The moving object is stopped when the received light outputs of the photoelectric sensors are balanced with each other preferably in a vehicle in an automated factory.
