Underwater Swimming Pool Bluetooth Solar Cleaning Robot
In my house I have a swimming pool, but the biggest problem with demountable pools is the dirtiness that is deposited on the bottom, that the water filter does not aspire. So I thought of a way to clean the dirtiness from the bottom. And as of other pool cleaning robots I made a homemade version.
Gathering Materials
1) Bluethoot microcontroler from a robomaker of clementoni ( or arduino + bluetooth module + ir sensor + motor driver board)
2) CPU fan
3) 2x DC motor
4) 2x running machine ( or 4 wheels)
5) 3.7v 18650 battery
6) Micro USB charger
7) Solar panel ( optional )
8) Other insignificant things :)
Coding ( If Using Arduino)
If you use an arduino here's the schematic and the code:
Make Some Modifications and Lubricate the Engines
As the IR sensor was soldered on the main board, I dessoldered it and extended the wires. I also soldered the fan on one of the engines.
In order not to rust in wather I lubricated the fan and motors
Assemble the Treadmill and Close Everything in a Box
The box doesn´t need to be waterproof because it will be sealed.
If you don't have a treadmill, 4 wheels can be used for the same result.
Seal the Box and Extend the Wires
First I sealed the box with silve tape but the water came in so I sealed it with hot glue by passing two layers.
The size of the wires depends on the height of the pool, I used about 1 meter.
Make the Filter and Glue It to the Robot
For the filter I used an old fabric, the suction system was made with a fan and two plastic cups, the bottom of the cups was the filter and the other the fan
Install the Solar Panel (Optional)
The solar panel was connected to the power input of the charger so it is possible to charge via USB or solar energy
I also put the IR sensor in front of the robot and glue two small pieces of styrofoam on both sides of the box to float well
Testing in the Water
My initial idea was that the box would be submersible but when I put it under water the cell phone has no bluetooth signal
After a while, the filter must be cleaned to avoid worsening the aspiration
