Abstract
A hull robot includes a robot body, at least one drive module for maneuvering the robot about the hull, an on-board power source, and a motive subsystem for the drive module powered by the on-board power source. A plurality of permanent magnet elements are associated with the drive module and each are switchable between a non-shunted state when adjacent the hull and a shunted state when not adjacent the hull.
