Rough/smooth negative surface unmanned aerial vehicle landing mechanism based on spinule array and bionic dry adhesion material

The invention discloses a rough/smooth negative surface unmanned aerial vehicle landing mechanism based on a spinule array and a bionic dry adhesion material. The rough/smooth negative surface unmanned aerial vehicle landing mechanism comprises a landing support, a steering engine, a steering engine arm, a lifting mechanism, a rough landing mechanism and four smooth adhesion and desorption mechanisms. According to the landing mechanism, the unmanned rotorcraft can land on a smooth negative surface through adhesive force generated by the action of the bionic dry adhesive material and the smooth negative surface; the rotor unmanned aerial vehicle can land on the rough negative surface through grabbing force generated when the spinule array pierces into the rough negative surface, and the rotor unmanned aerial vehicle can be switched from a smooth negative surface landing state to a rough negative surface landing state through the lifting mechanism capable of enabling the spinule array to move up and down.
