I followed the demo guide for the MIT Demos (found here - sorry I can't publish links: www dot ros dot org /wiki/mit-ros-pkg/KinectDemos/HandDetection), and I have a few errors.

I know they are created for Cturtle through Electric, but I am trying to get them to run on Ubuntu 12.04 and Fuerte (This is better than Groovy/Hydro because of the rosbuild/catkin discrepancy, correct?).

I am stuck on the section entitled "Execution" in the guide, specifically on "roslaunch handinteraction handdetector.launch" which yields the following:

... logging to /home/seil-user/.ros/log/e975edac-042c-11e3-ab2d-90b11c9cc7b4/roslaunch-EAB0201D-A-24982.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

The last line repeats indefinitely until I abort.

I've been troubleshooting for a while. These are the past errors:

• There used to be several XML errors which I believe I corrected line by line in multiple files.
• Furthermore, this error: "ERROR: cannot launch node of type [opennicamera/openninode]: can't locate node [openninode] in package [opennicamera]" used to appear until I installed "ros-fuerte-openni-camera"
• I also installed things while troubleshooting aside from what was in the guide: opennikinect and opennicamera
• While attempting to solve this problem, I did the following (I can't publish links): "sudo wget -P rospack find openni/lib github dot com/OpenNI/OpenNI/raw/43c256b554dcbe478644be73e29af16b3470f1c1/Data/SamplesConfig.xml --no-check-certificate" after reading answers dot ros dot org/question/9721/skeletal_tracker-crashes/ but it didn't seem to help

I'm new to ROS, and I'm not sure what changed between Electric and Fuerte that would affect these nodes. Any ideas on how to fix these errors? Thanks in advance.
