Magnetic walking robot developed with Fleet Robotics scrubs biofouling off ship hulls

A Northeastern University student, working as an intern at Fleet Robotics, refined a waterproof robot that grips steel hulls with switchable electromagnets in its feet and brushes away marine growth while walking autonomously. Several units can coordinate and recharge at docking stations; the system has been tested on a ship at the Woods Hole Oceanographic Institution.
