Hey, can and will provide information as it is helpful. Fairly certain my tf tree is setup right, and I believe I have covered everything in my launch file from the ros navigation stack tutorial and everything launches without error, I can see the map in RViz with my bot. When I create a nav goal though nothing happens. The movebase node never publishes anything on the /cmdvel topic.

When I echo /cmd_vel and some others I get:

"WARNING: no messages received and simulated time is active.

Is /clock being published?" (I am running gazebo and that publishes /clock, and I can confirm that with a rostopic echo)

Anyone have any idea where the disconnect would be?

Things I have looked into and tried:

• movebase is subscribed to /movebase_simple/goal
• movebase is set to publish on /cmdvel
• I can send my own cmd_vel commands fine that isn't in question
• I tried rostopic pub /movebase/goal movebase_msgs/MoveBaseActionGoal "header:...
• no success publishing the goal manually on that topic
• I don't see any disconnects on rqt_graph or the tf tree that would worry me.

I cant upload images, but you can check out my tf tree and rqtgraph output on my reddit post on the topic; https://www.reddit.com/r/ROS/comments/is9azx/navigationstacknomovementsaresent_after/

Any help would be greatly appreciated, I am just kind of at a loss for where to go next in debugging.
