Guilherme Martins wanted a simple Arduino-compatible board that he could use as a robotics platform, so he designed one. Called the Motoruino, he took a standard Arduino board and added an H-Bridge chip so that it can control two motors directly. Of course, you could certainly get the same functionality using an add-on board such as the MotorShield (or even by making your own on a breadboard). If you know you are going to be making a robot, though, I can certainly see that having everything together on a single piece would help make your project smaller and more reliable.
He is working on some final tweaks, and plans to release the project under the Creative Commons license. Cool stuff! [via Lets Make Robots]
