Title: Arducopter
Post by: Mega on January 20, 2008, 12:54:34 PM

This guy has attached an Arduino board to a RC helicopter.
Using the accelerometer of a Wii controller the Arduino adjusts the position of the main rotors
based on the tilt position of the heli. Very cool, I can't wait to see it flying!

Its an interesting idea, but you really need a 6-axis IMU to do that. Once the chopper starts to move around, you can't differentiate between sideways acceleration and tilt, unless you have gyros. Even then, the gyros will drift too much to be useful for more than a few seconds, unless you use a filter (like a Kalman filter) to eliminate the drift.
