PURPOSE:To improve the adaptability to the outside for a traveling object by attaching plural sensors for detection of obstacles to the front or lower side of the traveling object and correcting the direction of the traveling object according to the output states of those sensors. CONSTITUTION:A traveling object 1 revolves forward and reverse crawlers 15 and 16 by left and right drive motors 13 and 14 to move back and forth and revolve these crawlers. A pair of searching matters 17 and 18 are set to the object 1 at the areas opposite to a subject W such as a level difference, etc. These matters 17 and 18 are attached rotatably to an arm holder 19 of a holder 20. In addition, a limit switch 21 which is operated by revolution of the end at the other side of matters 17 and 18 respectively is fixed to the holder 20 via a support plate 23. Thus a steering mechanism is controlled in response to the output signal of the switch 21 so as to reduce an angle to the subject W when one of matters 17 and 18 has contact with the subject W in a drive mode of the object 1. Thus the direction of the object 1 can be corrected. |
