description	PROBLEM TO BE SOLVED: To provide an unmanned aerial vehicle capable of landing without being influenced by an adverse effect that may be caused when landing with a rotor thereof rotating at excessively high speed.SOLUTION: The unmanned aerial vehicle includes: a housing; a rotor that is rotated to propel the housing; a pressure sensor that generates a signal indicative of an air pressure proximate a bottom surface of the housing; and a processor configured to determine, based on the signal, when an increase in air pressure proximate the bottom surface is greater than or equal to a threshold value associated with the ground effect of the rotor. In the vehicle, the processor controls the rotor to cease rotating or decrease rotational speed to land the unmanned aerial vehicle upon determining that the increase in pressure is greater than or equal to the threshold value.
