PX4 has grown from a university project into one of the most widely adopted open-source flight control stacks — and it’s just one piece of the larger Dronecode ecosystem. In this talk, we’ll explore the architecture of PX4 as it stands today: modular, RTOS-based, Linux-compatible, and designed to power everything from quadcopters to VTOLs and underwater drones.

But PX4 doesn’t fly solo. We’ll also dive into how supporting projects like MAVLink, MAVSDK, QGroundControl, and the Pixhawk open standards work together to deliver a fully open-source stack for robotics and aerospace. Whether you’re targeting embedded Linux platforms, working with ROS 2, or deploying high-level autonomy, this session connects the dots across real-time systems, communication middleware, and full-system integration.
