I'm having trouble navigating the Turtlebot wiki and it seems mainly due to the crumbtrail structure.

Example page: http://ros.org/wiki/turtlebot_calibration/Tutorials/Calibrate%20Odometry%20and%20Gyro

Has this crumbtrail: turtlebot_calibration / Tutorials / Calibrate Odometry and Gyro

I would expect that clicking Turtorials would crawl up to the list of all tutorials. Or the root of the crumbtrail would point here: http://ros.org/wiki/turtlebot_apps

Perhaps I'm just a wiki idiot? :)

I can confirm that repeated attempts to launch rviz eventually works fine. I did not have to change the OGRE_RTT_MODE setting.

I also have this problem. After reading this post I just kept trying and within 3-5 times it would work.

http://answers.ros.org/question/11809/rviz-crashing-at-startup-with-baddrawable

This is on a Lenovo T60p running Oneiric with Electric.

The Turtlebot Bringup wiki doesn't describe what is different between the service and running minimal.launch manually. From my crude digging it seems that the service also runs minimal.launch but with some extra params and an argument added.

1) Is there a difference in methods to launch the Turtlebot?

2) How can I see the terminal output of the service (I often run the manual method just to see what's going on)?

3) Is there a way to remove the service from running at startup (admittedly stupid question but I'm stumped)?

Thanks, Ryan

Every time I run the kinect.launch I'm seeing it die and respawn constantly. It does transfer data that can be seen in rviz but this seems bad.

$ roslaunch turtlebot_bringup kinect.launch

This is what I see in the logs. When I Ctrl+C to kill it the data stops showing up in rviz so it doesn't seem like another version is running.

@Gemini - I was having the no camera issue for a while and ended up leaving it running for a while and it eventually cleared up. I could see something in the status messages going by that it failed to detect it at the USB port it was expecting it and switched itself. I know nothing of USB ID's but perhaps Turtlebot doesn't like moving around where things get plugged in?

@fergs - Dumb question, but where are the source install steps? A search takes me to this wiki page but there is no source install linked from any of the linked pages. http://ros.org/wiki/turtlebot_apps
