Making Line follower robot is one of the best way to get started with robotics and arduino. In this video, we'll be learning how to use the PID algorithm to make a line follower robot FAST. Using arduino, motor drivers and chassis, we'll put together a simple line follower robot using two IR sensors. Then using an IR sensor array, will make PID controlled version of the line follower. PID control stands for Proportional Integral Derivative where each constant affects the way the bot behaves. This video explains why we need feedback control and how PID controller is used.

It is called 'Bang Bang' from the first days of radio control in which I played a part, trying to fly aircraft. there were three positions ; neutral, or BANG full right, or BANG full left ( and they did make a bang noise sometimes, using rubber escapement motors) - no proportional in-betweens

First of all, awesome video, great explanation and demonstration of everything, i just added to my favorites! I just wanted to point out that you might've made a heavy load with that cool looking racing car model on top... and the tires/wheel you've chose does not have a good grip, its better to have something more soft to have better adhesion... another thing to consider is having bigger dc motors, those are very weak, specially with that load on top of it... please remember to take everything that ive said with a grain of salt because im not a professional at all... but i was wondering about that while i watch it run...

@shyam-ravi 8 ай бұрын

The IR sensors give an analog value rather than a digital one. So that adds to the precision in measuring the error.

I have no idea about any of this, but I kept thinking, why not use a fast linear interpolation value to smooth out between all the hard value changes. Seems like that might act like a dampener between values and really smooth things out. Besides, I like lerp functions in all of my game dev programming. It just works great for so many situations.

@adrianfernandes2004 5 ай бұрын

@_cul8r_ 5 ай бұрын

@@adrianfernandes2004 Linear interpolation or LERP is taking a value and then cutting it up into a smaller part, then cutting that part into another smaller part. In programming you can do this to crate a smooth transition from one value to another that is not instantaneous. Lots of info available online, just search for "How to lerp function).

Hello bro, first of all, let me congratulate you on the video. I'm having doubts about this line sensor. I have one just like yours, however, the sensor values always remain the same regardless of the surface it detects, whether it reflects a black or white surface, for example. I'm simply reading the sensors from the analog inputs, I'm not sure if I need to do something else?

How necessary was the integral constant? Was it relatively small? Would a larger integral constant yield a better response for an error biased towards one side? Such as one wheel having (consistently) more grip than the other side?

@jakesullivan3017 6 ай бұрын

In the case of one wheel having different properties (such as better traction), you would have separate PID values for each wheel.

How about using a QTR sensor? Me and my friends were able to make a similar fast PID based line follower, during the build we realised that the gap between the IRs was also a deal breaker (QTR being compact, solves this issue) . Also can you upgrade this to a maze solver next please, would be interesting to see that! Good video!

It cant take acute angles right? Im working on LFR from 2 years. Im using qtrx 16A line sensor with toshiba tb6612fng motor driver and teensy board, my lfr top speed is 6-7m/sec.

@shyam-ravi 10 ай бұрын

Yes, the PID alone isnt sufficient for acute anglee. So, I coded it so that once it leaves the line it checks the previous error and turns to that side till its back on the line. This worked well on the acute angles.
