Abstract

An aircraft includes: an aircraft body including rotating wings and motors that rotates the rotating wings; wheels arranged on both sides of the aircraft body and rotatably supported around an axis that extends in a left and right direction of the aircraft body; rollers that protrude forward and upward with respect to each of the wheels when the aircraft body is in a horizontal state, and are rotatably supported around an axis that extends in a tangential direction of each of the wheels; and a controller that controls a rotation speed of the motors such that, when the aircraft body is moved in the left and right direction along a vertical wall surface, the aircraft body is inclined forward to bring the rollers into contact with the vertical wall surface, and the aircraft body is inclined to a side where the aircraft body moves in the left and right direction.
