A question I've asked myself a few times! It can definitely be tricky, when you maybe aren't even sure what the problem is, to write a clear engaging question.

Disclaimer: I'm definitely new enough to ROS answers that I won't claim to have the answer, and haven't looked at your past questions so don't take this as personal advice, but my general tips are as follows:


  • Have a clear and concise title; it doesn't need to have all the details, but should give people a good idea of what issue you've run into
  • Use appropriate tags so the right people can find your question, or know to click in when looking through unanswered questions
  • Make the question as readable as possible; USE CODE FORMATTING please. I've .
  • Let us know what you've tried; people don't want to do your homework for you. Show people you've exhausted basic google search results and tried solutions from existing questions or github issues, or tell us why they don't apply.


  • Post lengthy, single format blobs of text and code and console output that make the whole thing unreadable
  • Post vague, unactionable statements and try to pass them off as questions; if you're looking for discussion and input from several users, I've found ROS Discourse to be a more reliable resource

The last comment I have is that the speed and quality of the help you can find on ROS Answers is strongly related to the popularity of the topic (see Kathrine's comment here). There are a ton of people on ROS Answers qualified to help with core ROS behaviors and popular packages like Nav2. But lots of unanswered questions are in niche areas where you're rolling the dice a bit with your question, in the hopes that someone qualified sees it. You can increase your odds of your question filtering to the top of the right person's feed by updating/commenting to "bump" the question if it goes unanswered for too long.
