Abstract
An unmanned aircraft includes: a processor; and at least two generators that generate thrust for the unmanned aircraft to fly, the at least two generators each including a corresponding one of rotor blades that produce airflows. In the unmanned aircraft, the processor generates a control request for changing a rotational speed of at least one of the rotor blades of the at least two generators to reduce a difference between rotational speeds, in response to start of sound recording by a microphone, and the at least two generators rotate the rotor blades in accordance with the control request.
