Story

Hi guys i'm Manikant savadatti, today we are going to build a vaccum cleaning robot using house old items. I had built a robot car, I wanted to upgrade it and build something which will help my mom in her house cleaning. Hence, I thought of making a vaccum cleaning robot. To clean the house we have to map the house using algorithms and AI but as this is a project in which we are going to build from scratch we will be making a line following robot which cleans the specific area ( place where track is present).In the next project i'm going to teach you guys how to map the room.

Step 1: Hardware

Making robot chasi :

Take a piece of cardboard and cut it to make a rectagular shape ( choose breadth and length size of cardboard according to your requirements )
Fasten the Bo motors to all the four corners of the rectangle board using srews
Connect the motors to the motor driver as shown above in the diagram
Connect the motor driver to the Nodemcu /Arduino as given int the code
If you use the connection as given above in the diagram you have to make few changes in the code
Hence to avoid this connect the arduino and motor driver as I have given in the code
Last step is to connect the ir sensor to microcontroller
Connect the positive and negative terminal of sensor to the +5 and gnd of arduino or motor driver
Connect the signal pins of sensor to pin 10 and 7 of arduino click here

Making Vaccum Turbine / Dust Collector

Making vaccum turbine: Watch the images as you read the given points

Take any plastic cup or any cylindrical tube or take an old bottle and cut it.
Make a hole and place the motor above it as shown in 1st image
Fix propellor or impellor to it from inside of the cylinder
Make a hole at the edge of cylindrical cup to let the air out (see fig 2)
Make a hole in robot chasi and place the turbine above the whole such that you can see propellor from the bottom of the car(see fig 4)
Place a wire mesh or net in front of propellor or at the output of the turbine
Take any cylindrical pipe and wrap sponge or any brush type material to make dust collecting roller(img 5)
I have made the dust collecting brush from a old glue bottle and a vessel cleaning sponge
You can rotate the roller using a motor by connecting motor to the gear of roller
Or you can leave the roller as it is because the roller rotates automatically due to friction with the floor, as the robot moves forward
The dust gets collected in the box ( image 8)
You can watch the above images to get better idea of it.

Step 3: Software :

I have written lot of comments in the code so that even a begineer can understand the code. Just upload the code into Nodemcu / Arduino.You can view this link click here or view my previous projects to know about how to use nodemcu using arduino ide.If you want to control the robot car using mobile instead of line following visit this link( click here) just paste the code of that project instead of the code given below

Code working:

When ir sensor detects the floor it will send the signal 1 and when it detects black line it sends 0 to the arduino/nodemcu.
When the left ir sensor detects the black strip robot will move right
When the right ir sensor detects black strip robot will move left
When both the sensors detect black strip the robot will stop
The main logic is the robot tries to move such that the sensors only detect the floor and the track should be present in b/w the sensors.
