Hi Crazyflyers

I'm thinking in develop an algorithm to inform the best values for roll and pitch values.

How about this? Is it possible?

My motivation is because my crazyflie, in flight doesn´t stop in one position always need correct the roll and pitch.

Have good flights.

Calibrating the accelerator might be one possible solution. I've posted a little bit about it in this post. Using balanced propellers is also very important to get the Crazyflie as steady as possible.

Youre always going to "drift" unless you have some form of absolute position measurement. Easiest would be something along the lines of using an external sensor (see the work using the kinect). In an ideal world you could double integrate the acceleration to get your position, but this wont work because your acceleration measurements are noisy.
