PURPOSE: To provide on unmanned carrier of which cost is reduced and reliability is improved by composing a traveling distance sensor and a sensor for steering of one sensor. CONSTITUTION: One sensor is composed of a light source 2 and a camera 3 mounted on the unmanned carrier, and the image of the reflection of plane light emitted from the light source 2 from a wall surface 4 is picked up by the camera 3. Since the light source and the camera are arranged so that the flooding axis of the light source 2 crosses the image pickup axis of the camera 3, when the distance between the unmanned carrier 1 and the wall surface 4 is changed, the reflecting position of the plane light in the image-pickup visual field of the camera 3 is changed. Therefore, since the distance from the reflecting position of the plane light in the image-pickup visual field to the wall surface 4 is calculated, based on this arithmetic result, steering is controlled by a steering means. Besides, since the image of a bar code 5 arranged at a prescribed position is picked up by the camera 3, the information of absolute position correction or direction change is obtained and based on this information, a traveling direction is determined by the steering means. |
