Well, I feel like this will be one of these sentimental entries, but not entirely. I would like to present my journey with quadrocopters, or drones in general. I first started to invest in drones when I was at my university. The passion developed in 2012 when I was defending my Bachelor’s degree and I decided to make a thesis about it. The topic was ‘Filtering and validation of measurements from accelerometer and gyroscope in Matlab/Simulink for a quadrotor flying robot’. In this blog post, I will tackle different aspects, namely software and hardware (mechanics and electronics).Continue reading
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.
