:arrow: i need ckt for building line following robot which can run fast, able to take sharp turns and stop with the end of line. i would not hesitate to use microcontroller but as i am newbie to it pls give me sufficient details. :!:

I now delete all my data on linefollowing, however, I remember something, you may give a clearer question and someone will help you. Don't ask general questions here.

I used to be a newbie a year ago, and I find that the ones who answer also our questions here are all technician, teachers or professors. So if you ask directly, they will help.

I'm coming back this forum, because I think I can study more, and I have to help beginners (as I used to be).

Fast Line Follower

When you say "fast" I immediately think of the 3PI robot which gets up to about 2 meters/sec.
My students are doing line following and line maze robots using the 3PI and the BOE-Bot. You may find the info on their page helpful:


I'll have a video of a fast 3PI posted there next week.
