1. An unmanned aerial vehicle comprising:
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
the unmanned aerial vehicle further comprises a suction state detecting part that detects a suction state of the suction part,
the control device controls the operation of the thrust generating part based on a detection by the suction state detecting part during a suction phase of the main unit with respect to the wall surface,
in a state suctioned to the wall surface, the main unit
supports a string body to which a moved body is attached, and
moves the moved body by winding up the string body with a winding machine, and
wherein the moved body is provided with multiple blowers, and the moved body is maintained in a prescribed attitude by controlling operations of the blowers.
