Something I forgot when answering @smac’s question about the current state: now that we have quite a few posts about ROS 2 on ROS Answers as well, it would be great to increase the number of ROS 2 topic experts as well.
There are already a few, such as @smac and @alsora and of course the OR crew, but I have a feeling we could improve on this.
Quite a few questions are about how to configure DDS (correctly), general network troubleshooting for ROS 2 (multicast troubles), how to create custom messages, why publishers and subscribers can’t find each other (different QoS settings ), whether certain packages have already been ported to ROS 2, how to design ROS 2 applications, integration with other middlewares/simulators/modeling tools and how to make use of new features in new releases of ROS 2.
So if you drink or in the morning, know a bit about ROS 2 and would like to help a fellow clueless developer out – or maybe not so clueless, as some questions about ROS 2 are really in-depth, then please check ROS Answers once in a while and see whether you can contribute.
Helpful link to just the ROS 2 questions: answers.ros.org/questions/tags:ros2.
Edit: there appear to be only 501 unanswered questions about ROS 2 so far (link), so with a bit of luck, we could achieve a perfect score if we get them all answered.
