Abstract: The application mode of robots is changing from cell to system one, which is of the need of practice as well as the evolution trend of robotics. And correlative technologies such as computer networks offer a strong support to the realization of multi-robot system. Cooperative robotics has already become a most important field in robotics. Thereinto, theory concerning multi-agent system (MAS), which is a branch of distributed artificial intelligence (DAI), has attracted the attention of most researchers who are angaged in cooperative robotics. And in this paper the authors pointed out based on the comparison of the two domains that it is an approach to scientific cooperative robotics for us to use the theories and methodologies in MAS for reference.
