摘要： Systems and methods are provided for transformation of a UAV from an extended state to a compacted state. The UAV can be transported in the compacted state. The UAV can comprise one or more segmented arms that can be folded to reduce the volume of the UAV. The segmented arms can be sealed to prevent ambient air, dirt, and or water vapor from entering the segmented arm. The UAV can comprise a cooling and air filtering system on-board the UAV.

摘要： A system and kit for dissipating heat generated by a motor assembly and methods for manufacturing and using same. The motor assembly includes a housing that defines an internal chamber. The internal chamber communicates with an air inlet and an air outlet each being formed in the housing, and can at least partially receive motor inner workings. A pump assembly can be included in the internal chamber for generating an air flow during operation of the motor assembly. The pump assembly can draw air into the internal chamber via the air inlet, generating an air flow within the internal chamber. The air drawn into the internal chamber is applied to the motor inner workings, and the air heated by the motor inner workings is expelled from the internal chamber via the air outlet. Thereby, the air flow advantageously can cool the motor assembly as the air traverses the internal chamber.

摘要： A method for controlling an unmanned aerial vehicle, and an unmanned aerial vehicle thereof are provided. The method includes: determining a first relative height between the unmanned aerial vehicle and a ground reflector directly below the unmanned aerial vehicle and a second relative height between the unmanned aerial vehicle and a ground reflector ahead the unmanned aerial vehicle; determining a combined relative height for reflecting a front terrain change according to at least the first relative height and the second relative altitude; and controlling a flying attitude of the unmanned aerial vehicle according to the combined relative altitude. The present disclosure allows a UAV to complete the terrain following function well when the flying speed is too fast or the terrain is quite undulating.
