AUTOMATIC WORKING SYSTEM, AUTOMATIC WALKING DEVICE AND STEERING METHOD THEREOF

A turning method is implemented in an autonomous vehicle having a central axis which divides the autonomous vehicle into left side and right side. In the method, the autonomous vehicle moves towards a limit; the autonomous vehicle monitors the location relationship of the vehicle with the limit; and the autonomous vehicle judges which side is closer to the limit when reaching a predetermined location relationship with the limit. The autonomous vehicle makes a turn and moves away from the limit, so that the distance from one side of the autonomous vehicle to the limit is always smaller than that from the other side to the limit. An autonomous vehicle and an autonomous working system are also disclosed.
