This paper proposes a new all-round Air-Land-Sea Unmanned Aerial Vehicle (UAV) and the automatic battery exchanging device. The new UAV is a quadrotor helicopter with two rolling protect-flames, and can not only fly in the air but also move on the ground, the wall, the ceiling and the water. Firstly, some new UAVs are presented to move on a wall in a horizontal direction. Secondly, a new automatic battery exchanging device for the UAV is developed based on ground running motion without precise landing from the air. The proposed method can complete the battery exchanging safely even in windy outdoor.
