Hi I am trying to use topological navigation demo of ICRA2011 Navigation using topological maps paper on Ubuntu 10.04, ROS Diamondback (installed from repository using debs). I am able to setup code and launch as mentioned in ICRA2011 link .

I am not able to find how to move robot around or is there any usage file? Video on ICRA2011 link is pretty impressive and I believe is in rviz.

Log file can be found at link. Terminal output can be found at link.

Update 1:

I had finally able to setup stack. Current teleoperation is by using erratic_teleop package and I can move robot around. A couple of questions:

I believe, in backgroup, topological mapping is happening but how do i legally stop the task. If I just terminate the launch (Ctr-C), how do I access map for reuse.
There are errors on console. Some of them are:

[ WARN] [1331911029.473383296, 31.400000000]: The base_scan observation buffer has not been updated for 0.50 seconds, and it should be updated every 0.40 seconds.

Complete log is here . Any help regarding these errors will be great.

Install the stack. instructions are available at http://ros.org/wiki/topological_navigation

$roscd topological_roadmap/launch

$rosrun rviz rviz
