Hi all,
we have initial documentation of our ROS port of the PX4 flight stack here:
https://pixhawk.org/dev/ros/sitl
It runs as normal ROS node when running on Linux, but the same code can be executed on the micro controller / NuttX as well. This is great for simulation or for prototyping new algorithms on Linux. Testers / contributors welcome!
We would like to acknowledge the Autonomous Systems Lab of ETH, who kindly provided us the Gazebo simulation framework we are using for this effort. This was a critical piece to get us going and we will continue to rely on it and contribute to it as our main robotics simulation framework.
We also have a Docker container with the setup, and people interested to help us build a continuous integration system with Docker / Jenkins and ROS would be very welcome:
