When I type "roslaunch turtlebot_bringup kinect.launch" in order to start my kinect for map building, I get these messages published over and over again. What do you think is the problem?

Your problem is in the error:

Cannot load nodelet /openni_camera for one exists with that name already

This suggests that openni_camera has already been launched. When you launch the map building demo it already starts the kinect for you, you should not start it seperately. If you're still having trouble please post all the things which you have launched and we can look for the conflict.

Even if I do not launch the demo, I still get the same error. Here is what I do :

"ssh -X turtlebot@192.168.1.11" "export ROS_MASTER_URI=http://192.168.1.11:11311" "rosrun turtlebot_dashboard turtlebot_dashboard&" "roslaunch turtlebot_bringup kinect.launch" Then I open rviz in a seperate terminal, because I am just trying to see data from the kinect right now, not make a map.
