In this video, I 3D printed and designed an ESP32-S3 based line following robot, and coded it in Arduino IDE all to fix some of the issues I had with the previous version (LF5 or LF-V on my channel).

Great job with the project and troubleshooting. Solving issues along the way is all part of the fun! Good luck in the competition.
Great project mate! All the best for the competition
Great video this should get way more views
good luck for the competition
Nice Project, and cool video. Pretty interesting!
Looks like a winner to me, good luck
Good job Brother 👏🎉
good project !
nice project! I'd like some spare IR arrays :)
(also I just like you rocntent in general)
Thanks bro
great project !
you might want some idea for improving the line follower, just see indonesian style line follower robot
Hey guys! Let me know if you have any questions about this thing here: bit.ly/4aorbNv (or in the comments section below).
Can you give me the line detection code of the 5-eye sensor?
Can you upload all the program files including the pcb diagram and code
Can you give me the line detection code of the 5-eye sensor?
Really cool project! Keep us updated on your progress and good luck in the competition.
Thanks bro
Yo your videos are cool dwag like where u from ? Virginia? like hell nah dude u look like u from the UK u feel me?
Thanks bro. I'm from Australia.
Have you tried using an esp32 cam as a sensor and communicate to the main board via i2c ? Not sure if it would be allowed by the competition rules though.
What was the name of the buck convertor you used?
It’s the mini560, you can get it from AliExpress
oh i was thinking about getting the mini 360 since it has good reviews but now eek lol, guess i'll have to check out some more options just incase. but just for your opinion would you recommend the lm7805 or the mini 360, i need to convert a 7.4v to a 5v output. ty@@hxtec32
You made a mistake when designing a new sensor board. You placed the middle sensors in such a way that they respond to the line asymmetrically. One has an infrared diode closer to the line and the other has a phototransistor closer. I know it's a matter of 2mm, but it makes the robot react slightly differently to the line on the right and left. At these speeds it may not matter that much, but it can cause slight oscillations at higher speeds.
Thanks lol. I’m still definitely a beginner when it comes to this sorta stuff, I don’t even know if the phototransistor + LED combo is the right one for me, or maybe the QRE1113GR is weird or something. Either that, or the way I placed the sensors is horrible because it’s hard to get the robot line following well. Thanks for your feedback
@@hxtec32 In my quite small linefollower I used KTIR0711S sensors, they are basically identical to QRE1113GR. However, I set them so that the middle sensors slightly overlap the line so that the robot does not have to turn without knowing where the line is. Additionally, all sensors are positioned identically in relation to the line. I don't remember whether the phototransistor is at the front or the IR diode, but the point is that these elements are not sideways to the line. My robot is called Tsubame ☺
is this a reupload? I swear this was uploaded yesterday or this morning
Yes, unfortunately the old title and thumbnail weren't doing well with the stats and stuff, and I figured, if I uploaded it now, there would be more people to see this due to the time of day.
@@hxtec32 You can update the thumbnail and title without reuploading the video. Because reuploading reduces the initial watch time value which gives a wrong idea about your video to the YT algorithm.
@@hxtec32 oh that’s sucks I see a lot of big RUclipsrs like to try out many different titles for the same video throughout the day but I think you can do it without having to fully reupload
Nice!!!
