Abstract:
1. A vibration-powered device adapted for flotation and propulsion on an upper surface in a liquid, said device comprising: a body having an internal water-resistant cavity and an external surface, the body further having a longitudinal axis, a front end portion and a rear end portion, a top side and a bottom side, a vibration mechanism disposed with the internal water resistant cavity and the vibration mechanism having a rotational motor adapted to rotate an eccentric load; a propulsion fin, said fin having a proximal end connected to the body, said fin having a free distal end opposite the proximal end, said fin having a top side adapted to be disposed at least partially above the surface of the liquid, said fin having a bottom side adapted to be disposed at least partially below the surface of the liquid; wherein said vibration mechanism when actuated is configured to oscillate the free distal end of the propulsion fin upward and downward; and a flotation member, the flotation member having a recess configured to directly secure over a portion of the external surface of the body, the flotation member having a shape configured to substantially maintain a portion of the top side of the body above the surface of the liquid and further configured to substantially maintain a portion of the bottom side of the body below the surface of the liquid when the flotation member is secured over the portion of the external surface of the body.
