Abstract: Intelligence and responsiveness are the two issues in architectures of autonomous robot vehicles. The key is how to make good tradeoff between deliberative reasoning and fast reaction. This paper explores a type of architecture, which is based on a distributed multi agent system. Agents can be dynamically reorganized to suit the various environments. A bulletin board system plays the role of assessing the surrounding situation and organization of the agents. Several models are designed to coordinate agents both in temporal and spatial.The computing coherent field based on TCP/IP supports agents to work together. The simulation shows that the architecture is desirable both in intelligence and responsibility.
