Automatic guided vehicle

Disclosed is a technique in which a laser area-measurement sensor is mounted on an automatic guided vehicle in a manner so as to include the rear thereof as a detection range, and in which the position and/or orientation of a cart are/is detected on the basis of the measurement result of the laser area-measurement sensor. This automatic guided vehicle is an automatic guided vehicle (100) capable of connecting with a cart (200) and transporting the same, and comprises a laser area-measurement sensor (105) capable of measuring the rear of the vehicle. The laser area-measurement sensor (105) detects the position and/or orientation of the cart (200). Particularly, on the basis of the measurement result of the laser area-measurement sensor (105), the automatic guided vehicle approaches a cart (200) that is in the rear of the vehicle and not yet connected thereto, and connects with said cart (200); travels rearward with the cart (200) connected thereto; or stops traveling if the cart (200) that was connected to and traveling with the vehicle gets disconnected and the positional relationship between the vehicle and the cart (200) no longer corresponds to the positional relationship in a state where the vehicle and the cart were connected.
