Underwater robots work together without human input, Princeton University

"This August in Monterey Bay, Calif., an entire fleet of undersea robots will for the first time work together without the aid of humans to make detailed and efficient observations of the ocean. The mathematical system that allows the undersea robots to self-choreograph their movements in response to their environment might one day power other robotic teams that - without human supervision - could explore not just oceans, but deserts, rain forests and even other planets."
