In order to improve the efficiency and safety of urban combat missions, the application of intelligent quadruped biomimetic robots in urban combat was studied. On the basis of analysing the development status of intelligent quadruped biomimetic robots and the needs of urban combat application, this paper focuses on the typical urban application styles of intelligent quadruped biomimetic robots from the aspects of battlefield reconnaissance and surveillance, offensive accompanying cover, fixed-point strike clearance, combat coordinated penetration, and combat support, and points out the problems that need to be solved urgently. The results show that this study has certain guiding significance for the development of intelligent quadruped biomimetic robot equipment and its combat application in urban environment.
