Hello ROS fans,

As part of my ROS learning process, I put together a tutorial on using 
OpenCV and ROS to do head tracking of a visual target.  The tutorial 
uses Python, a USB webcam, and Dynamixel AX-12+ servos on either a 
USB2Dynamixel controller or an ArbotiX.

You can find the tutorial at the following link:

I've heard from one other ROS user who has successfully run through the 
tutorial and got it working but it would be great if people would report 
back errors or omissions.
