Our LFR is fairly a good line follower robot, consists of low-priced electro-mechanical parts, electronic components, and a microcontroller chip-based processor circuitry. Bare essentials are listed ...

For an even more complex take on a microcontroller-free line follower, be sure to check out this slick-looking robot that features a hardware implementation of PID.

The robot uses a whopping 32 IR sensors to follow a black line across a concrete workshop floor, adjusting its path using a steering motor salvaged from a power wheelchair.

Class 5 student makes a national record in Robotics Aryaman, a class 5 student from Ludhiana, has made a national record for being the youngest Indian to make a line follower robot.

Finally, put the batteries in and place your finished LFR in the track (with the line printed on it using black colour). Place the LFR over the line, and switch on the LFR to see the action! ← Part 23 ...
