Cleaning up oil spills is very expensive. Robots could take over the cleaning buisness and clean up oil spills. It would also be good for marine life and humans too! MIT is creating Seaswarm Robots that absord and collect oil from the sea surface. These robots work together. They ditect oil spills on their own and can send the mesage to their robots group. If everything goes as planned, these robots will be available to use in a year.
