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.

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.

Learning to build a robot arm will teach you how to breadboard a circuit, how to program your Arduino, and how to work with moving parts.

The Arduino-based Kamibot, however, teaches kids how to code using Scratch, while offering fun customization with papercraft skins.

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.

This creepy Phantom of the Opera-style head promises to teach you how to code by building your very own robot.

We meet the creators of the Sphero RVR, the programmable robot that can seemingly go anywhere and do anything, all while inspiring a new generation of coders.
