Joseph,

Are you seeing any errors or warnings from move_base? It sounds like something may be going wrong as it tries to initialize itself. Perhaps its configured to run with a map, but one is not being provided?

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
