Robotics Stack Exchange should be used as the first step in requesting help. ROS Answers is available as read only resource, as it was officially deprecated as of August 11th, 2023.

ROS Discourse

To stay on top of the latest ROS news, join http://discourse.ros.org and subscribe to at least the general topic. Feel free to have a look at the historical posts.

For older posts please checkout the ros-users archive.

Please do not post questions on discourse.ros.org. Questions should be posted to Robotics Stack Exchange.

ROS Discourse is for news and general interest discussions. Robotics Stack Exchange provides a forum which can be filtered by tags to make sure the relevant people can find and/or answer the question, and not overload everyone with hundreds of posts.

When something fails

If you are attempting to debug a ROS system

  1. First try to troubleshoot using:
  2. If the troubleshooting guide fails to help, search for an answer, and ask a question if you don't find anything related on
  3. If you find an issue or wish to make a feature request, please see the next section

Suggestions for reporting issues/requesting features

  1. First, check the issue trackers: Known issues, often with patches or workarounds, are generally found there. If you have something to add to an existing issue, add it as a comment to the issue, rather than posting to the mailing lists.

  2. Next, check Robotics Stack Exchange to see if someone else has asked your question or reported your issue. And try a general search you may also find results from ROS Discourse the ros-users mailing list archive and other sites.

  3. If all the above steps failed, the best thing to do file a ticket.

If you're not sure what you found is a bug you can ask on Robotics Stack Exchange. If the problem is confirmed as a bug, please then open a ticket. Tickets are preferred if you are posting about a bug because they will be reviewed by the developers.

When you open a ticket the best way to demonstrate it is with a Short, Self Contained, Correct (Compilable) Example: http://sscce.org/ or a Minimal, Complete, and Verifiable example https://stackoverflow.com/help/mcve

Guidelines for Moderating

It is the responsibility of the community to maintain the community ethos. We use several public forums to communicate about our work: mailing lists, issue trackers and ROS Answers. If you see behavior in any of these forums that does not meet our community standards, please promptly respond following the guidelines below, always remaining courteous and polite.

Spam in general

  • Delete spam immediately. If the account has been created just for spamming, block the account as well.

ROS Answers

  • If a duplicate question is asked, comment on the new question to say that questions should not be duplicated, then delete the less detailed of the two.
  • If an inappropriate (e.g., rude or offensive) question or answer is given, quickly reword it if possible, including a comment with the reason for the edit. If it cannot be reworded easily, leave a comment as to why the question was deleted and delete it, suggesting that the submitter resubmit following the guidelines.
