Px4

The Professional Autopilot. PX4 powers any vehicle from racing and cargo drones through to ground vehicles. The powerful and uniquely flexible core of the Dronecode Platform is open-source, and available for you to use and customise as needed.

PX4 is used in a wide range of use-cases, from consumer drones to industrial applications. It is also the leading research platform for drones and has been successfully applied to under water vehicles and boats.
