Ozobots

The Ozobot Evo is a small line-following robot. Draw a path on a light-colored, flat surface with a black marker and this little guy will follow it. Use red, green, and blue markers to create a coded message to tell Evo to change speed, change direction, dance, or even count. You can also write code in a more traditional way using a simple block-based programming language on a tablet or desktop computer. When two Evos are near each other, they may stop and chat, complete with lights and sounds.
