According to the present invention, there is provided an unmanned freight transportation system which includes an unmanned freight transportation robot which travels along a preset moving route (C) on site (W). The unmanned freight transportation robot receives a control signal including a work instruction to establish a transportation work plan of the robot and sequentially reads out a plurality of land marks (M) spaced apart from each other along a moving route (C) to extract mark position information. The unmanned freight transportation robot travels to a destination(G) along the moving route (C) according to a set plan while confirming the current position based on the extracted mark position information. When the robot moves along the route between the land marks (M) and deviates from the moving route (C), the robot extracts position information by using a wireless signal transmitted from another unmanned freight transportation robot, the current position of which is confirmed on site (W), to confirm the current position based on the extracted position information, and corrects the transportation work plan. Then, the robot moves along the corrected moving route (C). |
