Have come across a weird one today. When launching the `move_base` node, there is no action server found at all. Initially I was launching in a launch file, but even doing `rosrun move_base move_base` provides no action server. The node launches fine, without any errors, and lists the topics that are unrelated to the server, such as `/move_base_simple/goal`, which works to move the robot. Using `rosrun actionlib axclient.py /move_base` also fails to connect. I haven't before used the actionlib interface for move_base.
Is there something fundamental i may be missing to cause this?
