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 creation of [Ondřej Staněk], this matchbox-sized line following robot is quite impressive. PocketBot’s 48mm x 32mm circuit board also acts as its frame, supporting the wheels, motors ...

Analog circuitry can be used instead of a microcontroller for many different applications, and this is one of them. The circuit consists of two op-amps that amplify the output of two ...

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 ...
