I tried it on answers and didn’t get any answers. Here I did get a couple of useful ones. So if “questions” are supposed to go onto answers.ros.org then discourse is only for announcements and declarations and actually not for any discourse.
I’m only being somewhat ironic. I thought of answers for geeky detailed questions about ROS (like stack overflow) and discourse for more conceptual, theoretical, and general questions. This is I guess a misunderstanding.
For example I had such a general question: “If I want to process the liar data so that I can find out a good current estimate of the closet obstacle plus its rate of change, should I be learning about Kaman filters or is that the wrong kind of processing?” I would have posted that question here. But I guess I will try somewhere else, right?
