We just realized how prevailing our system from 2009 still is: Marker based position hold and vision based pattern detection, all onboard, with a full companion architecture. Its great to start to see more of that more broadly, in particular in the open source space.
The video below (enable audio!) shows a detailed overview of the new Pixracer flight controller.
It is the 4th generation of the Pixhawk flight controller family (make: FMUv4) and like the first generations designed by the Pixhawk…Continue
PX4 has been flying Tailsitters, Tiltrotors and Quad Planes since last summer (instructions here), but we didn't get around to add support to our 3D Gazebo based simulator until now. As its standard-compliant MAVLink its easy to reuse and we've made it part of …Continue
The PX4 flight stack has an unique architecture: It uses a single codebase and mission logic for all vehicle types.
This allows us to easily support VTOL vehicles of any kind: Tailsitters with just two rotors, Tiltrotors and quad planes [INSTRUCTIONS TO BUILD YOUR OWN …Continue
The PX4 development has in the past been focused on smaller planes and wings not requiring a runway, but with lasers available for some time now it adding runway support made sense. We focused on high accuracy, as can be seen in the video. The plane is nice composite model and a Kickstarter project, the …Continue
Progress on VTOL for the PX4 Flight Core: Full forward and back transitions now with tailsitters and tilt-rotors.
We have now full VTOL support for tilt-rotors, in addition to tailsitters, which were introduced six months ago (video). People interested in flying these…Continue
This is a preview of the upcoming high fidelity simulation capabilities and native ROS / Linux port of the PX4 flight stack. It includes simulated cameras, inertial sensors, flight physics and even sensors like laser rangefinders. The same software running during software in the loop simulation can also be executed on a Linux computer for live flight, and leverages the…Continue
Call for VTOL test pilots! The PX4 standard firmware (master branch, downloadable via QGroundControl) supports first VTOL vehicle (duo-rotor, tail sitter). This video demonstrates the transition from hover - fixed wing - hover. Contact: …Continue
Having started as a crazy idea for just a small side project, the optical flow sensor quickly hacked together (we conduct our research on other topics) by a group of PhDs is now adopted by more and more systems. And because its an useful tool for research (not so much a research contribution), it made even a…Continue
This video illustrates a bit better why we believe the safety switch, buzzer and multicolor led help to greatly improve ground and air safety. The video just showcases a few new key safety features and is not a complete reference / mapping, as blink patterns might differ depending…Continue
The above picture shows PX4 Airspeed (in fact its so new this is even a picture of a (proven) prototype), a small, digital airspeed sensor. If features a Measurement Specialties (coincidentally swiss, too) 4525DO sensor, with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h). Its…Continue
Due to popular request, this post features a video of the multicolor led in action, and a second video how to single-handedly unplug DF13 connectors.
This tutorial page again summarizes how to unplug and shows an alternative strategy in…Continue
Almost exactly one year after the first PX4 announcement, we would like to introduce our newest member of the family, Pixhawk! For those familiar with the existing PX4 electronics, it is…
The image shows the successful flight of an extremely simple fixed wing controller tutorial (flies GPS waypoints or in manual mode, has support for MAVLink parameters, runs automatically synchronized to the attitude filter). Simple can mean many things, in this case we are…Continue

Finally the last missing board from the PX4 series has been released, the PX4FLOW smart camera module. It can replace GPS in indoor and outdoor applications and provides a metric position close to the ground with only very little drift. It is essentially a microcontroller…Continue
