I made a SUPER FAST Line Follower Robot Using PID!

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

man, i liked your video a lot, thanks for posting it. I think you could make it go super super fast

[@monneratrj]

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...

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]

And how you do that?I jus wanna learn abt it

[@_cul8r_]

@@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).

[@yogpanjarale]

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

[@shyam-ravi]

The PID algorithm does that automatically

[@Yuvraj_333]

[@edamhbaieb2091]

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

[@shyam-ravi]

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

[@alexandermaverick9474]

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...)

Maybe u can integrate ann (artificial neural network) to it, so it's can learn the track, to make it some kind of intelligence enough to run even faster.

[@roboticsguru5173]

yeah we can but in some competitions this thing is not allowed

[@chaitanyagaikwad2664]

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!

[@shyam-ravi]

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!

[@virtuosorv7422]

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?

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