Your Roomba’s getting a new big brother, though this one’s not for the living room. The company behind the robotic vacuum cleaners announced today a new product called a Seaglider, which is an autonomous submersible robot designed for a number of underwater uses.

The robot has a range of hundreds of miles and can stay at sea for months at a time if need be. This way it can collect all kinds of data for a longer period of time than if it had a human inside, meaning more accurate numbers. Scienticians love that stuff.

No word yet on how the finished machine looks, but we’re hoping that when Skynet goes live these destroyer divers will be on our side.
