Hi,

I am just getting started with ROS, so I try to follow this : 
http://openrave.programmingvision.com/index.php?title=Working_with_Cameras

But I couldn't find checkerboard_detector, even after checking out
https://cmu-ros-pkg.svn.sourceforge.net/svnroot/cmu-ros-pkg 

Where can I find that package please ?

Thanks.
