PROBLEM TO BE SOLVED: To provide an unmanned carrier that enables stable travelling along a guide line irrespective of a travelling direction.SOLUTION: An unmanned carrier 1A travelling at least in a first direction and in a second direction orthogonal to the first direction along guide lines 2a and 2b disposed on a road surface comprises: at least one steering wheel 5; steering wheel turning means 6 that causes the steering wheel 5 to be turned; imaging means 3 that photographs an area A including the guide lines 2a and 2b, and generates image data of the area A; illumination means 4 that illuminates the area A so as to generate a halation area on the image data; and an illumination turning mechanism 7 that causes the illumination means 4 to be turned in accordance with a turning angle of the steering wheel 5. In any of image data generated upon travelling in the first direction and image data generated upon travelling in the second direction, the guide lines 2a and 2b and the halation area are not overlapped. |
