The [**dronecode foundation**](https://www.dronecode.org/) is setting the standards in the drone industry with open-source projects. They support projects such as **[PX4 autopilot](https://px4.io/)**, 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](https://github.com/eProsima/Fast-DDS) as the communication middleware to Bridge between these two components**, and we created the [RTPS/ROS2 Interface: PX4-FastRTPS Bridge](https://dev.px4.io/master/en/middleware/micrortps.html).

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](https://micro-ros.github.io/).

Both From [Nuno Marques](https://www.linkedin.com/in/numarques/), a [PX4](https://px4.io/) great contributor.

PX4 has a complete ecosystem of [commercial drones](https://px4.io/ecosystem/commercial-systems/) supporting this autopilot, and a long list of supported hardware.
