How to build a Line Follower robot

Welcome to my channel! In this video, I’ll guide you through the process of building your very own line follower robot. Whether you're a beginner or an experienced maker, this tutorial will help you create a fast and efficient robot that can navigate complex routes with ease.
Here is my Github repository - github.com/NYDEREK/LineFollow...
Materials :
- IR sensors KTIR0711S
- Motors Pololu 3071 10:1
- Motor drivers TB6612FNG
- Tires Kyosho Mini-Z tires
- Wheels you can find in my repository
- Battery Dualsky 150mAh 2S 7.4V
- Bluetooth module HC-05

Hello
Your video is very interesting and bravo for your performamnce!
I have a question, how do you take turns at this speed? I can’t with the PID. The robot goes straight ! Thanks for your help!

If your Line follower is too heavy and wheels don't have enough adhesion to the surface he will drift on 90 degree bends. One of your wheels goes backwards and one forward depending on the speed diffrence between their speeds is bigger or lower as you can see in my code on github. Sorry for timing but i am checking comments not as frequently as i should

Why not use esp32 or arduino ?

[@nyder1331]

STM32 is faster than Arduino. A typical arduino with atmega is only 16MHz, the STM32F103 I used in my line follower is 72MHz so it is faster, you can also use ESP32 with 200MHz, but small microcontrollers without legs are difficult to solder with a soldering iron. I wonder if an ESP32 module with a built-in Wi-Fi antenna would be heavier than my stm32 and HC-05. You can use whatever you want, line follower is a very simple project, so even a basic arduino will do the job quite well. The STM32 was my choice because I was trying to learn how to program it.

Your video was very helpful. Can I get your mail / any social where I can contact with you !!! I am also trying to build a line following robot. I would greatly appreciate your thoughts and expertise.
