Introduction: 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.
Step 1: 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 :)
Step 2: Coding ( If Using Arduino)
If you use an arduino here's the schematic and the code:
Step 3: 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
Step 4: 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.
Step 5: 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.
Step 6: 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
Step 7: 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
Step 8: 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
