I am running the turtlebot navigation demo in fuerte and 12.04 Precise. Everything works fine up until I try and set a nav goal in rviz, then nothing happens. The console output says that a goal is being set, but the turtlebot does not move and no messages are sent on move_base_simple/goal. I am using the versions of rviz and the demos directly from the repositories with no modifications. Does anyone know why this might be happening?

It sounds like you don't have the proper goal topic configured in rviz.

In particular, you should set the 2D Nav Toal topic to /move_base_simple/goal in the Tool Properties window.

Take a look at http://ros.org/wiki/navigation/Tutorials/Using%20rviz%20with%20the%20Navigation%20Stack

Unfortunately, I have that set properly already in rviz. When using rostopic echo to listen to the "move_base_simple/goal" topic however, nothing gets sent when I use the "2D Nav Goal" button in RViz. Also nothing gets sent when I hit the "2D Pose Estimate" button and listen to "initialpose"

Are you running ROS over a network? Which machine are you running 'rostopic echo' on?

I am running ROS between two computers over my lab wireless network. I have tried running rostopic echo on both the workstation and the mobile computer, with the same result.

I would walk through the network setup and make sure everything there is in order: http://www.ros.org/wiki/ROS/NetworkSetup

Have you checked your frames.pdf file ? You can check the transforms that are published. Please type below command on another terminal and frames.pdf file will be generated: rosrun tf view_frames

You should get a tree like the following link --> /map -> /odom -> base_link -> openni_camera. If anyone link is missing, turtlebot won't move and you get warning that particular link is not found. Hope this helps !!
