PURPOSE:To ensure an effective work area for an unmanned carrier by applying the switch control to the obstacle detecting range of an obstable sensor in accordance with the traveling speed of the unmanned carrier. CONSTITUTION:An unmanned carrier 1 contains an obstacle detecting range deciding part 5 which applies the comparing arithmetic to the drive data on the carrier set previously based on the drive detecting signals detected by a speed detecting device 4 as well as a decelerating point detecting device 3 which detects a decelerating point for command of the deceleration. While an obstacle detecting range switch means 6 switches the obstacle detecting range of an infrared-ray sensor 7 based on the deciding result of the part 5. Then the part 5 decides the switch or non-switch of the detecting range based on the drive data stored in a driving data memory part. Thus the detecting range is switched. When the sensor 7 detects an obstacle in a due range, a detecting signal is sent to a driving control part and the carrier 1 is urgently stopped. While the drive of the carrier 1 is continued in case the part 5 decides the non-switch of the detecting range. |
