I have just started working with the ROS navigation stack, specifically the move_base package. The /move_base node publishes lots of topics, one of which is move_base/action_topics. As opposed to every other topic i have seen this one is missing the initial slash, so it is "move_base/action_topics" as opposed to "/move_base/action_topics". I cannot echo any information from this topic either and i'm not sure why.

My guesses are that it is a custom topic or has something to do with the missing /.

I have tried rostopic list but the topic in question does not show up. I have also tried rostopic echo move_base/action_topics but nothing is displayed.
