In 2017, WHOI engineers Jeff Kaeli and Robin Littlefield entered the WHOI Office for Technology Transfer Pitchathon, intending to win translational funds to advance what was then just an idea, the Asymmetric Thruster. This novel propulsion system, now a patented and demonstrated technology, produces forward thrust - as with a traditional multi-bladed propeller - but what is unique about the Asymmetric Thruster is that it also allows you to steer without any additional control surfaces. By altering the speed of rotation within a single revolution using just a single blade - the Asymmetric Thruster both propels and maneuvers. The simplified design, eliminating the need for fins, rudders, and additional motors, reduces weight, drag, and cost. Two years later, the team licensed this innovative technology, launched a startup company: ARMADA Marine Robotics, Inc., and are now looking to revolutionize marine submersibles.

Commercial and research operations require winches for hauling and retrieval in marine environments. Their many applications make them valuable, and often necessary, pieces of equipment. Currently available marine winches have large on-deck footprints, are difficult to service, are single purpose, require costly task specific fabrications, and are immobile once installed on deck. This lightweight, compact winch is a small footprint, frameless winch adaptable for a variety of marine applications. The winch is capable of hauling and supporting heavier loads, all while being lighter than traditional winch designs.
