Fish Tank and Swimming Pool Cleaning Robot

Abstract

Cleaning big fish tanks and swimming pools has been a very hard and time-consuming task. Although filters can be installed in small aquarium, they must be installed in large numbers. In this process a robotic vehicle is used which revolves around the bottom surface of the tank or pool and collects the sediment dust particles deposited at the bottom within a short period of time. This robot has a moving unit which is remote controlled. The wheels are driven using servo motors whose speed and direction are controlled by a microcontroller. The cleaning unit consists of a DC motor pump and a bio-chemical sponge filter. The DC motor pump sucks the dirt water from the bottom which is mixed with dust particles. This dirt water is made to flow to the sponge filter using tubes where the dust and dirt particles get deposited at the sponge filter and clean water flows out from the cleaning unit. By this process the water gets cleaned. Pressure of the suction is set in such a way that it does not affect the fishes in the fish tank. The sucking operation, movement speed, turning of robot are all controlled remotely by sending signal to the microcontroller. A remote is used to send control signals. Rechargeable 9V batteries are used as the power source. This project has numerous advantages such as time saving, less effort and higher cleaning efficiency. The limitation of this process is it cannot be used breeding tanks where newborn fishes and eggs are present.
