The dronecode foundation is setting the standards in the drone industry with open-source projects. They support projects such as PX4 autopilot, a widely used autopilot for consumer and professional drones.
Nowadays these drones are composed of a microcontroller for real-time critical applications such as the Autopilot, and a companion board for accessory applications. Dronecode adopted Fast RTPS/DDS as the communication middleware to Bridge between these two components, and we created the RTPS/ROS2 Interface: PX4-FastRTPS Bridge.
This interface allows you to run ROS 2 applications within many drones (including cheap drones) using the Drone telemetry and sensors, nice right?
This interface was the inception of Micro-ROS, and in the near future, the original interface will be replaced by Micro-ROS.
