With the social needs and the development of science and technology, robot technology had been developing in depth, and the application range of the mobile robot is more and more wide. And the robots application environment has become increasingly complex, while the task requires more precisely. So multi-robot system has gradually become an important branch of robotics research .In the numerous multi-robot system research direction, multi-robot operation stalking question has been the focus of research. This paper researches on cooperation capture for mobile multi-robots. We use finite state machine principle to do research on cooperation capture for mobile multi-robots. It could simplify the process of design and achieve maximum results with little effort. At last, this method using finite state machine realizes cooperation capture for multi-robots system.
