Fleet Robotics builds submersible, autonomous robots that live onboard commercial ships and clean and inspect the hull while the vessel is in service. The robots crawl vertical and inverted underwater surfaces to remove biofouling and dry bulk residue without requiring divers, port visits, or human supervision. Each pass also collects hull condition and coating integrity data, which the company turns into vessel performance insight for operators. Founded in 2022 and based in Charlestown, Massachusetts, the company was previously known as Bluetech Robotics.
