We have made it work, but it takes a good understanding of how the robot and camera work together to get it right.

How are you planning on handling the situation where a robot parks right in your line of site?
There is a "simple" way though. Just use the servo position as your "sensor" for a pid loop ther turns your robot/turret. The servo follows the image tracking results and the robot follows the servo. We did this in 2006.
The advantage is the servos can react very quickly. Nice job by the way!
