Although slopes or cliffs are needed to be inspected every 5 years, this law is not observed now. Due to few artisans and danger of dropping down, there are demands of using robots to inspect slopes or cliffs. Because the slope or cliffs surface is usually huge, rough, uneven, sometimes not easy to access, and has occasionally steps which have 300[mm] at most, there is no robot which can inspect whole slope efficiently now. The passive rotating spherical shell multicopters which are being developed by our research team can avoid crashes by contact with some objects and can efficiently move along walls using passive rotating spherical shell as a wheel. In this paper, we propose a new inspection system for cliffs with passive rotating spherical shell UAV which can move up, down, and horizontal direction and can stay near the targets. After making the system, we confirmed these function in section 4.
