Pixhawk is an independent, open-hardware project aiming at providing high-end autopilot hardware to the academic, hobby and industrial communities at low costs and high availability. We are one of the projects constituting the Linux Foundation DroneCode project. It is supported by the PIXHAWK Project of the Computer Vision and Geometry Lab of ETH Zurich (Swiss Federal Institute of Technology) and by the Autonomous Systems Lab and the Automatic Control Laboratory as well from a number of excellent invididuals (Contact and Credits) and available from 3D Robotics.

We are always looking for new developers! Get in touch via the Forum (Web View).

Autopilot Software

The Pixhawk autopilot module runs a very efficient real-time operating system (RTOS), which provides a POSIX-style environment (i.e. printf(), pthreads, /dev/ttyS1, open(), write(), poll(), ioctl(), etc). The software can be updated with an USB bootloader. We support multiple flight stacks.

Autopilot Hardware

PIXHAWK is the industry standard autopilot, designed by the open hardware development team in collaboration with 3D Robotics.
