An Arduino Mega Pro Mini handles the logic, sending PWM signals to a DIY servo. The chassis consists of a modified Crazy Cart, selected for its absurdly tight turning radius.

Inside the BeatBot an Arduino reads 9 infrared sensors for line detection at 100 samples a second. A digital servo controls the Ackerman steering mechanism to follow the line on the track or floor.

Remember, we need two identical infrared sensor cards; one for left side, and other one for right side! → Part 24: ATmega8 Line Follower Robot (LFR) Project – Part 2/2 ← Part 22: Bootload an ATmega ...
