running kinect on ros

edit

I'm in the process of trying to figure this out myself, so I won't be able to help you too much but I can point you in the right direction.

You'll need freenect_launch and libfreenect

sudo apt-get install ros-indigo-freenect-launch
sudo apt-get install ros-indigo-libfreenect

Then you can launch it with (make sure the Kinect is connected, it will tell you to connect it if not)

roslanch freenect_launch freenect.launch

When it starts it will output some messages like below, which apparently is normal

...
[ WARN] [1447125024.427412294]: Using default parameters for IR camera calibration.
[ INFO] [1447125027.019823318]: Stopping device RGB and Depth stream flush.

After this you can follow the tutorial from the openni page, starting at step 3 http://wiki.ros.org/openni_launch/Tut...

For more information look around on the freenect and openni pages.
