The Pololu 3pi Robot is a fun interface to program. It has two motors, a display screen, LED's, three buttons, light sensors, and a ton more places to connect anything you want. This could be the beginners learning toy, or the expert's launch pad, either way it is fun to use. The Pololu 3pi robot is at its heart an Arduino, making it open source and able to be programmed to do anything. It can be a maze solver, an autonomous moving robot, a moving sound player, etc. Use your imagination and come up with something cool.

I enjoyed making this robot and installing programs on it. It comes with enough accessories that you can make something really cool. Have fun!
