Fleet Robotics is a green-tech startup developing an underwater robot to inspect and maintain ship hulls. At Fleet, we are looking for an extraordinary mechanical engineer to join our robotics team. Challenges include designing a low-cost, mass-producible robot platform that can withstand water depths, harsh sea-states, and years of deployment with minimal maintenance. The ideal candidate has worked on robots or other complex electromechanical systems, and has experience with constrained designs. As one of the company’s early employees, this role offers the ability to make significant contributions to a novel and meaningful environmental application working with a small, close-knit, and fast-paced team. We are tackling a thousand-year-old problem: the growth of biofouling on ships. Biofouling is the growth of microorganisms, algae, barnacles, and larger ocean organisms on the ship’s hull. As a ship delivers goods around the world, the growth of these organisms significantly increases the drag forces on the hull and in doing so, significantly increases fuel consumption. Ships are the world’s largest consumers of carbon-heavy fuels (called bunker fuels). Conventionally, the commercial shipping industry handles biofouling in two ways: preventatively, by coating the ship’s hull in a highly toxic paint that discourages growth, and reactively, by stopping operations every 6-months or so to have divers scrape off years of fouling (along with some toxic paint). This is akin to deciding never to brush your teeth because you go to the dentist every five years. There is a better way. Our small autonomous robots live on the side of a ship’s hull for years, gently removing the earliest stage of biofouling on a regular basis. This early-stage biofouling is easy-to-remove slime. The technical challenge lies in having a robot that can withstand a marine environments, adhere to the ship hull while it is underway, and clean entirely autonomously. By removing slime often and early, we prevent the growth of macrofouling, significantly reduce fuel consumption, and prevent the spread of invasive species from port to port.
