AQUARIUM SYSTEM WITH ROBOTIC UNDERWATER TOYS

摘要

PURPOSE: Provided are underwater toys and a habitat system to enable the toys to move through the habitat system. More particularly an aquarium assembly facilitates autonomous movement of self propelled underwater toys simulating aquatic creatures. CONSTITUTION: The display system for presenting aquatic devices comprises: a container for holding a liquid; a unit for causing the liquid to circulate in the container; and an aquatic toy apparatus that is sized to fit within the container having a motor, a generator of power for driving the motor and a propulsion member operatively connected to the motor to cause movement of the toy apparatus, wherein the aquatic toy apparatus is weight balanced to be approximately neutral weight when immersed in the liquid whereas the combination of the circulating liquid and the motor causes the aquatic toy to move within the container.
