# ROS (Robot Operating System)

ROS (opens new window) is a general purpose robotics library that can be used with PX4 for drone application development. It is only officially supported on Linux platforms.

ROS benefits from an active ecosystem of developers solving common robotics problems, and access to other software libraries written for Linux. It has been used, for example, as part of the PX4 computer vision solutions, including obstacle avoidance and collision prevention.

WARNING

tip ROS 2 is the "latest and greatest" version of ROS. The PX4 development team recommend that all users upgrade to ROS 2!

# ROS Setups

PX4 supports both the "original" ROS and ROS 2, with the following configurations:

# ROS Support Roadmap

Unveiled at the PX4 Developer Summit 2020 (opens new window) (and ROS World 2020 (opens new window)), the PX4 Development team, announced the plans to support microROS.

  • microRTPS: microRTPS bridge with Fast DDS (The current stable ROS 2 interface)
  • micro XRCE-DDS: DDS on PX4 (Next step!)
  • micro ROS: ROS 2 on the PX4 (Our Target!)
