Abstract: An unmanned aerial vehicle includes a main unit having a thrust generating part for flying in air, a suction device that has a suction part and is fixed to the main unit, and a control device that controls operations of the thrust generating part and the suction device such that the suction part is configured to be suctioned to a wall surface by the operation of the suction device to allow the main unit to be attached to the wall surface, wherein a suction state detecting part that detects a suction state of the suction part, is provided, and the control device controls the operation of the thrust generating part based on a detection by the suction state detecting part in suction phase and/or departure phase of the main unit with respect to the wall surface.

Abstract: A control system 2 for a flying object includes at least one marker 6, which corresponds to control information related to the control of the flying object, a reading unit 12 for reading the control information, and a flight information transmitting unit 14 for transmitting flight information to the flying object based on the control information read by the reading unit.

Abstract: Problem: To provide a control system and a control device for a flying object that autonomously flies the flying object without using a GPS and without storing a flight route. Means for solving the problem: A control system 2 for a flying object includes at least one marker 6, which corresponds to control information related to the control of the flying object, a reading unit 12 for reading the control information, and a flight information transmitting unit 14 for transmitting flight information to the flying object based on the control information read by the reading unit.
