UNMANNED AERIAL VEHICLE-BASED LOAD CONTROL METHOD AND DEVICE, AND UNMANNED AERIAL VEHICLE

摘要

An unmanned aerial vehicle-based load control method and device, and an unmanned aerial vehicle. The unmanned aerial vehicle comprises: an unmanned aerial vehicle body, propeller arms connected at first ends to the unmanned aerial vehicle body and having adjustable lengths, propeller blades connected to second ends of the propeller arms and having adjustable sizes, and a processor mounted within the unmanned aerial vehicle body. The control method comprises: on the basis of a carrying object of the unmanned aerial vehicle, determining a load gravity of the unmanned aerial vehicle; on the basis of the load gravity, determining a target lifting force of the unmanned aerial vehicle; according to the target lifting force, determining a target size for the propeller blades and a target length for the propeller arms; adjusting the propeller arms to the target length and adjusting the propeller blades to the target size, so as to enable the unmanned aerial vehicle to control the propeller blades to rotate to generate a lifting force to carry the carrying object. The control method avoids energy waste of the unmanned aerial vehicle, so that the energy of the unmanned aerial vehicle is fully utilised.
