Good quality estimation of tilt angles such as roll and pitch is desired when it comes to an UAV control. Without good quality signal a proper work of flight controller is nearly impossible. However, the task of filtering is not an easy task, especially when it comes to DSP (digital signal processing). It is even harder when digital filter is inadequate. In this post a mechanical filter is presented that allows to significantly improve attitude estimation in terms of roll, pitch and yaw.
It was quite a long time since I have written something about my QuadroCopter. Well the time has come. I have prepared a shot movie to which I invite you to watch.

Below you can see 3D printed components for my quadrocopter:
There was a need to create a new landing gear for QuadroCopter which would be lightweight and flexible in a way. With help came the FreeCAD. It is an open source CAD software which can be successfully used when designing 3D parts. Below in a figure on the left is a 3D model and on the right is the printed part. The part was printed using RepRap 3D printer.
