Abstract: An unmanned aircraft includes: at least two generators generating forces to fly the unmanned aircraft, each including a rotor blade generating an airflow; a sensor detecting a tilt of the unmanned aircraft; and a processor controlling the generators to control flight of the unmanned aircraft. The processor: obtains an output force adjustment trigger for the generators; obtaining the trigger, causes each generator to individually operate at least until the tilt of the unmanned aircraft detected by the sensor satisfies a predetermined condition; determines a reference value related to an output force of each generator from a value related to the output force of each generator when the tilt of the unmanned aircraft satisfies the predetermined condition and a positional relationship between the generators; and controls the flight of the unmanned aircraft, using the reference values determined.

Abstract: An unmanned moving body includes a directional speaker that outputs sound in an orientation direction and a processor that obtains one or more instances of sensing data. The processor: determines whether or not a second target is present in a vicinity of a first target in accordance with at least one of the one or more instances of sensing data; calculates a positional relationship between the first target and the second target when it is determined that the second target is present; and determines a first position of the unmanned moving body in accordance with the positional relationship and causes the unmanned moving body to move to the first position, the first position being a position that places the first target and the second target within a range over which the sound from the directional speaker reaches at at least a predetermined quality.
