  • Movable floating object and driving mechanism therefor
    Patent number: 8371888
    Abstract: A movable floating object includes a floatable body and water pumps mounted on the left and right sides of the body respectively. Intake tubes are coupled to the pumps through intake valves respectively. Discharge tubes are coupled to the pumps respectively. Exertion of force on the pumps forces water out of the pumps and through the discharge tubes, and release of the force creates a vacuum inside the pumps that sucks water into the pumps through the intake tubes and the intake valves respectively. The floatable body moves forwards when same force applied to the pumps and turns when the forces apply to the pumps are different.
