PURPOSE:To enable excellent running, by providing an information processing means which performs the running along a prescribed objective line easily and surely. CONSTITUTION:A sensor 3 is formed that a plurality of parallelograms A linking a number of links 6 with pivotally supporting are formed so that the diagonal lines (l) can be on a straight line, and the parallelograms can be expanded and contracted freely. A bulldozer 2 contacts a lead 5 via sensors 3, 3. The sensor 3 is provided with a device 8 detecting one interior angle theta formed with adjacent links 6 and a device 9 detecting the total length of the sensor 3. Further, a device which detects the vertical and horizontal inclined angles alpha and beta of the sensor 3 is located at the supporting part of a sensor support 10, and a prescribed operational processing is made based on the detecting signal from the detectors, allowing to make efficient the running of the bulldozer 2. |
