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.

Abstract: A spreading system for a plant protection UAV is provided, including a material inlet, a material conveying mechanism, and a material spreading mechanism. The material inlet is configured to dock with the material box. The material conveying mechanism includes a screw mechanism and a driving device connected to the screw mechanism. The material spreading mechanism is used to spread a material in the material box. The driving device may drive the screw mechanism to rotate, so as to transfer the material from the material inlet to the material spreading mechanism, thereby quantitatively feeding the material spreading mechanism and improving the spreading uniformity of the plant protection UAV. A plant protection UAV and a spreading control method are also provided.

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.
