For usage scenes and landing stability of the helicopter, a kind of bionic leg landing gear based on multi-link structure is proposed to replace the original landing gear. The landing gear can effectively improve the helicopter’s complex terrain take-off and landing adaptability. In this paper, the design concept of the bionic landing gear is given, and the research of design and verification technology is carried out. Firstly, based on the six-leg scheme, the structural design of the bionic leg landing gear is given. Then, the drive/control system and the collaborative control method is proposed based on the landing gear structure. Finally, based on this prototype, the tests in laboratory and in real environment are completed for function verification. These research indicate that lightweight design of multi-link bionic landing gear is achieved. And through its drive/control system, the buffering of the landing gear landing process and the stability control of the fuselage are effectively realized. Compared with the traditional landing gear, this kind of landing gear has the advantages of landing attitude adjustment, and complex terrain adaptation.
