PX4 is an independent, open-source, open-hardware project aiming at providing a high-end autopilot to the academic, hobby and industrial communities (BSD licensed) at low costs and high availability. It is a complete hardware and software platform, much like a computer, and can run multiple autopilot applications (e.g. the PX4 native flight stack or APM). 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 and international 3DR distributors.
- Merge branch 'master' of github.com:PX4/Firmware by LorenzMeier (2014/10/20 15:22)
The PX4FMU 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. PX4 communicates to ground control stations via MAVLink and can be operated with QGroundControl 2.0. All software is open-source and BSD licensed.
