Abstract: An unmanned aerial vehicle (UAV) comprises a central body, a plurality of arms that extend out from the central body, and a plurality of rotors. Each arm has one or more joints that segment the arm into a stem portion proximal to the central body and one or more branch portions distal to the central body. The one or more joints permit the one or more branch portions to move horizontally relative to the stem portion between an extended state and a compacted state. The one or more branch portions are arranged substantially parallel to a perimeter edge of the central body in the compacted state. Each rotor in the plurality is attached to the one or more branch portions.

Abstract: A method for supporting aerial operation includes obtaining a real-time location of an aircraft, obtaining a location of a supply station, obtaining a location of a next waypoint, and controlling the aircraft based on a status parameter related to a flight status of the aircraft associated with the real-time location of the aircraft. Controlling the aircraft includes controlling, in response to the status parameter satisfying a first preset condition, the aircraft to fly to the next waypoint; and controlling, in response to the status parameter satisfying a second preset condition, the aircraft to fly to the supply station.
