I'm new to ROS (however I was the co-author of a similar project DROS at http://dros.org), so please excuses my newbie questions about ROS. Anyway:

1) any good simulator should allow you to simulate the calibration steps. So if you could point me to the tutorials to do this it would be most appreciated.

2) domhege, I'm sure they are, but the tutorials are not the most easiest to find (they seem rather split across pages, and sometimes are missing vital prerequisite), can you please point me to the tutorials I should be following...

3) re drive the robot around. I've just started up the empty world simulation as shown above, then run that keyboard teleo command above, and when I press "q" a few times, the robot in the simulator doesn't not move. Any ideas what I maybe missing?

4) Ryan, when I run that command it opens up, but I just see a black screen. Any ideas how to see the particles, kinect output, etc.

etc. And the output of "roslaunch turtlebot_navigation gmapping_demo.launch", seems saying "[/openni_camera] No devices connected.... waiting for devices to be connected" - which seems to be looking for the real Kinect - how do I tell it to use a simulated Kinect?

1) any good simulator should allow you to simulate the calibration steps. So if you could E.g. most DMU's have a roll bias, so the simulator should have a hard coded roll bias. Could you please point me to the tutorials to do this it would be most appreciated.calibrate a robot in pure simulation?
