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.

I'm not sure why this was in my notifications, but this was actually made really well
Same for me, this actually earns a subscribe
What an evolution from the Technowright! Love your videos, I've been watching them for years!
This is really cool. I have been researching PID for a bit now and this came up in my notifications and I'm glad it did. Great video and good distribution of humor and information. Thanks for showing the progress and the mistakes you made, mistakes are often much more valuable than the result. Thanks!
Its maybe the fastest line following robot I've ever seen
Great work❤
Finally an explanation of derivative and integral error correction that makes sense.
Also, nice video overall!!!
It is unbelievable how bad teachers can explain this topic right 😂
Was thinking the same thing, if we had good and practical example while we were being taught, we would have loved it and understand so much better
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
Damn! This was awesome!
Ah Yes! Quality Content❤
Excellent video!! Hopefully we get em more often though.
Awesome project, and thanks for your contribution
Best video i ever saw in youtube.. Good explaination bro
Finally he remembered that he also had a TH-cam channel. ❤❤
3:26 MOST HELPFUL TY CUS IT HELPED ME TO MAKE A PROJECT REPRESENTING MY SCHOOL !
Good job bro❤❤
Nice! Great style, and very educational.
Awesome vid! ❤🔥
Damnn!! Amazing video Shyam, and awesome work. Loved it!!
You are superhero ❤❤❤
Thanks from Egypt
thanks for sharing, would you make a video and tell us the PID tuning detials?
Amazing job and expalination.
Superb Shyam. Very well presented. Engaging and entertaining… All the best
Thank you!
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...
really nice, what was your base speed for the motors (to be specific what was your pulse width for the PWM)
Bro i want the list of foot prints that you used for pcb design .
Hi ! which app did you use on the phone for controlling the PID ??
Hello sir!Nice video! can you please specify what sensor you used? and does it have a digital input or analog?
Great video!
love this video , so much fun
bro what are the components that you used separately on the pcb, and which app did you use to control the pid, can you please mention.
Proud of you my son.... Hope to see you on another level....❤
Thanks a lot!
Have you tried doing it with all analog circuits, except maybe for an esp32 to let you set the tuning values remotely?
What is your kp and kd value that you're use?
So nice innovation. Hats off🎉🤝👏
Great video, thanks for sharing it. Although I do have one question, how were you able to determine the error value accurately with only 5 IR sensors!?, I've been trying to do the same thing but couldn't see it happening with only 5 sensors.
Please reply if possible
The IR sensors give an analog value rather than a digital one. So that adds to the precision in measuring the error.
Could you fit a kalmar filter on the arduino to underdampen the steering?
subscribed! Nice video
Bro explained PID the best way possible!!
fuck
Superb Shyam..keep rocking 👏👏👏
very nice video and presentation. You are very well articulated and a pleasure to watch.
Bro can we use printer motor?
Can you please also share the 3D design
I am doing a project similar to the simple version that you show and apperantly I do everything correct but when a switch on the gears are not working.
After watching your video I guess that the battery I am using is the problem. What kind of battery should I use?
Is this follows LSRB algo. As well ?
Have you tried your line following robot with dead end map and does it follow the line with a mixture map(white line with black bavkground and black line with white background)?
How about front wheel drive?
May i ask the link of the parts?
Nice project! What PCB design software did you use?
Easyeda
VERY COOL, great work. But uhh, do you have the Code for the smart glasses
Hi im quite new to arduino but im just wondering how you got the arduino powered without plugging it in anywhere? I mean looking at 1:57 there doesn't look to be any cable from the battery to the USB or barrel plug. how is it working?
What IR sensor are you using? please tell me specific name...
thank you!
Another addition you can do to increase speed is speedup on straight sections and then slow down to normal or break on turn can significsntly boost speed
The PID algorithm does that automatically
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?
i want to know your parameter Kp,Kd,Ki ,multiP,I,D is always 1 ?
bro's smart as hell
Please provide a roadmap on how we can make one of these
What to learn first?
what software is used to set the PID value?
love it!
Hi friend. Great video. What’s at J1?
Totally worth it
bro Funtastic
At intersection point , from 3 lines which line the robot will be choose ?? How robot decided about it ?? 🤔. Is the robot will be choose a line randomly every time when it reaching at that intersection point or you programmed robot to choose a specific line from 3 lines or any other idea you taught the robot 🤔 ??
hello, can you do it with backward mode or can you guide me code with motor backward ? Thank you so much
My brother what sensor are you using TT please tell me
Please teach about your program
hello
how to oder the pcb
please guid me
love from pakistan. A good quality engineering video at last 👌
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.
And how you do that?I jus wanna learn abt it
@@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).
@@_cul8r_ dude thanks for explaining I kinda get it
how can I use qtr 8rc sensor with this code?
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?
In the case of one wheel having different properties (such as better traction), you would have separate PID values for each wheel.
Awesome 🎉😊
Dang, your accent is so good
I agree
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.
Do you have any idea to crack acute angles?
5:30 your app looks similar to "Bot reboot's" pid controller app, did you made this app or using his app for pid tune?
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.
@@shyam-ravi you mean, in this code it can take acute angles well?
Yes, it handles the acute angles quite well. As you can see in the video.

Very nice video shyam. Keep on rocking
Thanks!
Can you tell me the list of items you used please asap
Gold 💛
A very good video. Which transistor to use?
Which transistor are you referring to?
You mahe great videos. Have you got a new channel or have you just stopped? Updated ones would be great
How to purchase this project
Awesome!
I am starting doing projects with Arduino and I am interested to start doing the simple version you show in this video. What are those components where you put the photoresistors? Sorry for asking but I am not familiar yet with electronics and Arduino. By the way really cool video dude I enjoy it!
Think he used IR detectors not photo resistors.
Thank you.
I have see that I will need to do it with phototransistors, are they similar to the IR detectors? Or at least if I buy this IR detectors to practice will be similar?@@aakashjana6225
can it be used for maze like pathways ??
please reply asap
You can, but that would require separate algorithm or sensors
do you have to use an encoder?
Nice
it's hardly "fast", but good job on the presentation and project! (see videos from Japan's linefollowers or maze solvers, or from Europe's Robochallenge linefollowers...)
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!
Thanks for the suggestion, I did consider a qtr sensor, however due to availability issues I went this one. Maze solver would be an interesting project!
Nice! But we would all appreceate it if you would include some of the details in the coding as well
why not using a linear image sensor with a ligth? you get much more accuracy
Superb
Bro please make a explained video on coding part
Great work. Just one question, Can we use PID in Arduino UNO?
Yes, you can
Yes
It's just a equation which can be written in lines of code

Which app you use to adjust kp, ki, kd value for this experiment?
I guess he just made a simple app on his own for his phone that just sends values to the esp via bluetoot
Super video
Can i also use higher speed motor?
Yes, you can use any rpm motor. But you have to tune the PID values.
@@shyam-ravi where can i dm you if u do not mind ,really need some help
Instagram @thetechnowright
messaged you
Bro i messaged u on insta
where is the app download link
IS THERE A CALIBARATION AND RUN BUTTON? or just turn on power and run
First 10s calibration and run. There is no button for it
@@shyam-ravi how can i contact you bro
@@shyam-ravi bro i followed your exact tutorial, nothing happens, even bluetooth of esp32 does not show up on phone
'Hot Glue' 😂
Great project 👏🏻👏🏻
Can anyone help me out.. 😐
I have tried my best... But still could not make it...
My line follower is not tracking the lines nor responding to the ir sensor...
