This paper proposed skidding movement method for tracked vehicle that uses the wall reaction force. There is a demand for tracked robot to inspect in the plant automatically. In the plant, usually there are many obstacles such as stairs, steps, and so on. So, tracked robot is proper for plant inspection, because crawler has high road abilities. However, tracked robot has a problem that it is difficult to adjust the position of the robot. This paper tries to solve this problem by lateral skidding movement using wall reaction force. Originally, tracked vehicle cannot move lateral direction, but if we use forces from wall, tracked vehicle can move lateral direction.
