The research on coordination of multiple biomimetic robot fish is focused on basic theory and key technology for systematic control and cooperation of future multiple underwater robots. By employing the behavior-based approach presented in this paper, many coordinate tasks can be achieved efficiently. Taking account of the motional characteristics of the fish and its environment, six primitive behaviors...
