We have developed an inspection equipment of a building with air injection. The apparatus can move over wherever we want to transfer it in a building with air injection and insertion. However, it could not fly with poise due to its flexible and simple structure. In this paper, first we confirmed basic features of the equipment to establish a system with air injection. Next we proposed how to wing the equipment steadily and avoid obstacles. Lastly we described future subject of the equipment.
