Quadcopter stabilization system using Wii Motion Plus

If you’re contemplating a quadcopter build here’s a way to add stabilization hardware without breaking the bank. The BaronPilot project uses an Arduino and a Wii Motion Plus module to ensure an even keel for your flying projects. The hardware inside of the Motion Plus includes two gyroscopes, which the BaronPilot monitors for changes in your flying rig’s orientation. The project serves as a co-pilot by differentiating between movements caused by the remote control, and changes due to wind or other outside factors (like hitting the quadcopter with a stick as seen in the video after the break). It should all translate to less chance of crashing due to operator error.
You can pick up a Motion Plus for less than twenty dollars, a deal when compared to the IMU boards that we usually see in quadcopter builds which usually run more than twice that amount. It’s an I2C device which makes it easy to hook up to just about anything. This project has native support for Teensy, Arduino Nano, and Arduino clones using an ATmega328 chip. But the portability of the Arduino platform should make it easy to tweak the code for use with just about any microprocessor.
