Abstract: An unmanned aerial vehicle includes: a sensor including at least a microphone that generates sound data; and a processor. The processor determines a quality of a target sound by using the sound data generated by the microphone, acquires a positional relationship between the unmanned aerial vehicle and a sound source of the target sound by using data generated by the sensor, determines a destination to which the sound source is to move based on the quality of the target sound and the positional relationship, and presents target movement information that prompts the sound source to move toward the destination.

Abstract: An information processing method includes the following steps performed using a processor: obtaining first region information indicating a first region; obtaining first position information indicating the position of an unmanned aerial vehicle tethered to a mobile tethering body using a tether; determining, using the first region information and the first position information, a first destination which is a destination of the mobile tethering body; and moving the mobile tethering body to the first destination. The first destination is a position located at least a predetermined distance from a point which is on the boundary of the first region and located the shortest distance from the position of the unmanned aerial vehicle, in the direction from the point on the boundary of the first region to the position of the unmanned aerial vehicle.

Abstract: Unmanned aerial vehicle includes a microphone which picks up a sound emitted by a target, an actuator which extends to change a position of the microphone, and a processor. The processor obtains positional relationship information which indicates at least one of a position of the target or a distance from the unmanned aerial vehicle to the target, causes the unmanned aerial vehicle to move to a first position at which the unmanned aerial vehicle and the target have a predetermined positional relationship based on the positional relationship information, and causes actuator to extend toward the target after unmanned aerial vehicle moves to the first position.

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.

Abstract: An unmanned aircraft includes: a sensor that includes at least a microphone that generates sound data; and a processor. The processor determines the quality of a target sound by use of the sound data generated by the microphone, identifies a sound source direction from the unmanned aircraft to the sound source of the target sound by use of data generated by the sensor, and controls an unmanned aircraft state that is a state of the unmanned aircraft such that a direction of a sound pickup area is aligned with the sound source direction, in accordance with the determined quality. The sound pickup area is a range in which sound pickup quality of the microphone is higher than that of another area.

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.
