Abstract
UAV driven by battery is used to search indoor of a suffering building and plumbing of plant, but it can only fly at short time because of few burdens of the battery. To solve the problem mentioned above, this paper proposes an adsorption mechanism using magnets which can be mounted on UAV. So UAV can hold its own position by using the adsorption mechanism without driving propellers. We designed the adsorption mechanism in consideration of mounting on UAV and evaluated it.
