Abstract: A method of controlling movement of a plurality of movable devices includes determining, by a processor, at least one of a first priority level or a first safety zone for a first movable device of the plurality of movable devices. The method also includes determining, by the processor, at least one of a second priority level or a second safety zone for a second movable device of the plurality of movable devices based on information relating to the second movable device. The method further includes generating, by the processor, a collision avoidance measure to avoid collision with the second movable device during movement based on at least one of the first priority level, the first safety zone, the second priority level, or the second safety zone.

Abstract: The present application relates to a control method of an aerial vehicle. The aerial vehicle may comprise a propulsion structure for providing flight power and a spraying apparatus for spraying a material. The control method may comprise determining current target information of the aerial vehicle during a process of the aerial vehicle performing a spraying task, wherein the current target information indicates wind field strength of a downward pressure wind field generated by the propulsion structure; determining, based on the current target information, a desired relative flight altitude of the aerial vehicle corresponding to the current target information relative to the material being sprayed below the aerial vehicle; and controlling the aerial vehicle to fly toward the desired relative flight altitude.

Abstract: A return flight control method includes obtaining return-flight-evaluation information in a return flight mode, controlling an unmanned aerial vehicle (UAV) to return to an alternate landing area in response to that the return-flight-evaluation information satisfies a preset requirement, and controlling the UAV to return to a return point in response to that the return-flight-evaluation information does not satisfy the preset requirement.
