Intelligent light-weight foreign matter grabbing device and method of unmanned aerial vehicle

Abstract

The application discloses an intelligent light foreign matter grabbing device and method of a unmanned aerial vehicle, which comprises a clamping jaw, a telescopic rod and a rotating shaft, wherein the clamping jaw comprises a pincer end and a fulcrum groove arranged on both sides; the telescopic rod is connected with the clamping jaw at an end away from the pincer end; the moment of force from the fulcrum groove to the pincer end is fixed; the length of the telescopic rod is adjustable; the moment of force from an end of the telescopic rod away from the clamping jaw to the fulcrum groove is a variable moment of force; and one group of the rotating shafts are rotationally connected with the telescopic rod. The gravity of the unmanned aerial vehicle carrying the clamping jaw and the connecting arm is used to lift and loosen the bird nest through the fulcrum groove, and then the bird nest is grabbed, so that the situation that the unmanned aerial vehicle is insufficient in power to destroy the stable bird nest when the bird nest is directly grabbed can be avoided. The force required by the unmanned aerial vehicle to be applied is adjusted, so that the situation that the unmanned aerial vehicle is damaged due to inertia contact with surrounding cables or other live bodies in the process of clamping the bird nest is avoided.
