This paper is to systematically sort out, summarize and analyze the research status of design morphology in the field of military bionic robot design, so as to provide ideas and references for the design of national defense construction and military equipment. Firstly, starting from the connotation of design morphology and combined with bionic design theory, this paper explains in detail how design morphology can assist the development of new military bionic robot by integrating multidisciplinary knowledge; secondly, according to the different combat domains of military bionic robots, this paper summarizes the current situation of design morphology helping the development of military bionic robots at home and abroad, and summarizes the characteristics of the design of different types of military bionic robots from the three aspects of land, underwater and air (inter) military bionic robots; finally, this paper summarizes and analyzes the development trend of the application of design morphology in the field of military bionic robot design, and prospects the future research methods and research priorities of design morphology helping military equipment. Design morphology is a theoretical system that emphasizes system. It is an innovation of design morphology under the biological incentive mode integrating bionic methods. It can effectively support the fusion innovation in the field of military bionic robots. With the continuous development of artificial intelligence technology, the application of design morphology in the field of military bionic robot will gradually evolve to the direction of man-machine integrated intelligent design.
