Problems solved by technology
[0003] Multi-rotor UAVs are generally equipped with support legs for landing. When the flight controller controls the multi-rotor UAV to land, the support legs support the body. The support legs of existing multi-rotor UAVs are mostly fixed. For the support structure, the lower ends of the supporting legs are mostly in the same plane, and generally 3 to 4 are set. For the generally relatively horizontal road surface, the multi-rotor UAV can land relatively smoothly, but for the uneven road surface, it is generally forced to land. , the body of the UAV is prone to tilt, or the uneven road surface bumps into the body, causing damage to the UAV

The invention relates to an intelligent multi-rotor unmanned aerial vehicle, comprising a body, a rotor support arm is arranged on the body, rotating blades are arranged at the cantilever end of the rotor support arm, and a plurality of telescopic legs are arranged on the body, which are located on the telescopic legs. The secondary distance sensors are respectively arranged on the ground, and the detection ends of the secondary distance sensors point to the ground, and the detection ends of the secondary distance sensors are in the same plane, and the secondary distance sensors send the detected distance signals to the flight controller for processing, and the flight control The controller sends a control signal to the drive unit, and the drive unit drives the telescopic outriggers to expand and contract, and changes the length of the telescopic outriggers. The distance signal detected by the secondary distance sensor is analyzed and processed by the flight controller, and the length of the telescopic outriggers is changed to suit the For the landing on the uneven road, the intelligent multi-rotor UAV can ensure the stability of the UAV stop and avoid damage to the UAV.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an intelligent multi-rotor unmanned aerial vehicle. Background technique [0002] A multi-rotor UAV is an aircraft driven by a radio remote control device or a program-controlled autopilot device. It has also been widely used in the civilian field in recent years. Traditional multi-rotor drones include a body and multiple rotors on the body. Each rotor is connected to the drive shaft of the respective drive mechanism on the body. The drive mechanism drives the rotor to rotate at high speed in the air, constantly pushing the air downward. , thus generating an upward lift force, driving the UAV to fly upwards. At the same time, the flight controller adjusts the speed of the drive shaft of the drive mechanism, thereby indirectly adjusting the propulsion of each drive shaft, thereby realizing the control of the flight attitude of the UAV. [0003] Multi-rotor UAVs ...
