You're reading the documentation for an older, but still supported, version of ROS 2. For information on the latest version, please have a look at Galactic.
ROS 2 Documentation
The Robot Operating System (ROS) is a set of software libraries and tools for building robot applications. From drivers to state-of-the-art algorithms, and with powerful developer tools, ROS has what you need for your next robotics project. And it’s all open source.
Since ROS was started in 2007, a lot has changed in the robotics and ROS community. The goal of the ROS 2 project is to adapt to these changes, leveraging what is great about ROS 1 and improving what isn’t.
Here you will find the official documentation on ROS 2, the newest version of ROS.
If you’re looking for documentation on ROS 1 (i.e., ROS as it has existed for several years, and what you might be using right now), check the ROS wiki.
Where to start
Newcomers and experienced ROS users should consult this overview of our user-centric content to find what they’re looking for.
Installation pages will help you setup ROS 2 for the first time. You can choose your platform as well as the installation type and distribution that suits your needs.
The Docs Guide explains the ROS 1 and ROS 2 documentation infrastructure. It is helpful in understanding where specific resources live, how to ask questions, and which sites are maintained.
Tutorials walk you through small projects and sample usage of ROS 2, so you can learn the ropes by actually using the tools. They are organized by progression of necessary skills, making it the best place to start for new users.
How-to Guides answer all your “How do I…?” questions as short and to-the-point as possible, so you can find the information you need without needing to work through the narrative nature of the tutorials for context.
Concepts are high-level explanations and background information on core ROS 2 concepts, which should provide some context for topics covered in the tutorials.
Contributing is what makes ROS 2 great! We have guides on best practices and methodology for contributing new ROS 2 content as well as migrating existing content from ROS 1 to ROS 2.
Getting help is always encouraged. Here you’ll find several ways to get answers to your questions or start a discussion.
