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 ...

An Arduino-based robot for people who don’t know how to build robots "Sparki" ideal for teaching kids (or adults) how to program robots.

There are always a few high-tech toys on display at the Consumer Electronics Show (CES) in Las Vegas, and this year is no exception. Perhaps the most charming is Ozobot, a tiny robot that follow ...
