Folks,

            I’m trying to get the Navigation Stack working for a homegrown robotic platform and have setup the stack as described in the robot setup tutorial.

To test the stack/setup I am using the Sending Simple Navigation Goals tutorial.   Navigation stack, as well as the simple_navigation_goals node are launched as described in these tutorials.

Now here’s the issue:  though, /move_base node is created, it seems that the action server is not created, and hence  simple_navigation_goals spins on…

        //wait for the action server to come up

  14 while(!ac.waitForServer(ros::Duration(5.0))){

  15     ROS_INFO("Waiting for the move_base action server to come up");

  16 }

In addition to launching the move_base node, is there anything else that needs to be done to create the action server…. 

Thanks

Joseph
