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 ...

The robot follows a circular track with no problem, and while we can see it’s not without flaws we doubt it would be possible to make a simpler follower.

There’s no denying it. Super small robots are just cool. [Pinomelean] has posted an Instructable on how to create a mini line following robot using only analog circuitry. This would make a gr… ...

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 ...
