This is Robolobster designed by Joseph Ayers. It is now on display now at the Design Life Now show at the Cooper-Hewitt National Design Museum in New York City
It’s controlled by an electronic nervous system that mimics that of a lobster, so it can sneak across the ocean floor with the flexibility and agility of the real thing. It was designed to detect underwater mines, collect marine biology data, and test water for pollution,making the it kind of an undersea cousin to those chemical-sniffing robot dogs we saw a few months back.
