Mavlink and PX4 Autopilot 1: Connection and Reading Messages

Hey there! Struggling with Mavlink and Pixhawk? You're not alone. I've been there, and that's why I wrote this article. It's a no-nonsense, easy-to-follow guide that'll help you get your autopilot talking in no time. We'll start with the basics, then get our hands dirty with some code to read those Mavlink messages. Whether you're a student, hobbyist, or just curious, this piece has got you covered. So, let's dive in and demystify this tech together!

Helicopter: A 2D Height Control Simulation

This 2D helicopter game enables testing a linear PID controller using a Python environment. As the virtual helicopter is on the web, you only need Python code!

A Virtual Drone On Web

I uploaded a virtual multirotor on my web. This should be straightforward to interact with Python so that beginners and engineering students can use it for better understanding. It is virtual so nothing to break! Channel:

VTOL UAV is Becoming Dominant - Dev. Series # 3

It is about the flight controller design. The tailsitter has 2 motors and 2 elevons. Unlike the quadcopter with 4 motors, balancing in the middle of the air is not straightforward. I mean that the flight controller for the quadrotor is relatively trivial to implement. However, for the tailsitter, it is not so.

VTOL UAV is Becoming Dominant - Dev. Series # 2

Last time, I built the test model for a tailsitter VTOL - a pretty rugged model. Yet, it does not bother me. I wish to connect all the electronics and see if this can exert some force and torque onto the body regardless of the ability of attitude or angular rate control.

Why Do Professional Drone Developers Use PX4 Autopilot?

A gentle introduction to PX4-Autopilot, the most popular open-source project for autonomous vehicle autopilot.

VTOL UAV is Becoming Dominant - Dev Series # 1

Vertical Take Off and Landing [VTOL] is becoming a dominant Unmanned Aerial Vehicle [UAV] type. At first look, the VTOL looks like just an airplane. Indeed, it is an airplane with a wing. However, the fixed-wing airplane needs a runway. Although a pilot can throw small UAVs, they need a dedicated runway to carry payloads. The runway is the very problem - building or using a runway is expensive!
