How to build a Line Follower robot

[@PhG1961]

Great ingenuity, I'm impressed!

nice, thanks for guide

thanks for the guide

Hello, your car looks very nice, but you only have two tires. Have you written code to maintain balance, or is balancing not an issue because the center of gravity is at the rear?

hey bro i cant understand or get the code and all things (connections mainly )by your repository can you simplify it for me please like i want you to just give me the code and connections so i can make a similar bot for my competetion

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!

[@nyder1331]

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

@@nyder1331 Any way to add suction?

[@pasquentmax]

​@@nyder1331 Is it not a problem for the engine to change direction suddenly? Your tight turn is made out of PID in open loop? How do you not swing out of the turns?

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.

@@nyder1331Great video. By the way, isn't STM32 ADC peripheral much better than ESP32? ESP32 tends to be unstable, while STM32 has more resolution (up to 16-bit vs 12-bit) and might also be more stable (haven't tried it yet though). Have a good day

Do you sell robots?

[@巫堵-h8f]

Make yourself,its not very difficult.

[@mubasshirrahaman8053]

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.
