hi,

for a project i started to use ROS to control my turtlebot, but i keep having problems to make my own map. I followed the tutorials on http://learn.turtlebot.com/ but at tutorial 11 i'm stuck.

Every time i run this code: roslaunch turtlebot_navigation gmapping_demo.launch

I receive next message :

0.2.7/src/openni2_driver.cpp @ 631 : Invalid device number 1, there are 0 devices connected.

I think the problem is that this code is for an other camera, but i don't find the right code to launch the gmapping for the Orbbec Astra Camera. Can some one help me pls.

The camera is well installed and it works when i connect the turtlebot with a screen, i can see a 3D immage in RViz
