The snake robot has been something of an institution in the Carnegie Mellon robotics labs. Every time I visit the school, the biomimetic robot has seemingly learned a new trick. This week, the school announced it has added swimming to the list.

Testing actually began last month in one of CMU’s pools, with the snake robot outfitted with new housing designed for underwater navigation. Work on the project began last July. “I’m surprised that we made this robot work as fast as we did,” professor Howie Choset said in a release tied to the announcement. “The secret is the modularity and the people working on this technology at CMU.”
