The purpose of this paper is to describe the feasibility research of marine vehicles with oscillating fin propulsion control system and it’s application systems. The oscillating fin propulsion system was designed and constructed to be combined with a ship model. The system’s feasibility was confirmed by tank tests using the ship model. As a result, several advantages of the oscillating fin system were found out. As the first application of the technology, a robotic fish has been proposed, intended as an amusement attraction for aquariums, using the single fin propulsion system. Its capability of untethered 3-dimensional movement has been confirmed. And as the second application, the twin oscillating fin system has been tried to an new underwater vehicle. It has been confirmed to be possible to promote the vehicle smoothly without yawing.
