Your best bet is to run a small laptop like an EEE pc on the robot or a wireless camera so that you can do your processing in roborealm.  Use roborealm to find the center of the ball relative to the center of the screen and then pass that to the ATMEGA via a serial connection. Your atmega will handle driving the motors based on the error between the center of the ball and the center of the screen.  Take a look at Steven's project on the color tracking cannon to get some ideas.

good luck!

Yes, you can find that in the tutorials section of the website.

Basically, if the X coordinate of the COG is to the left of the center of the screen them move right, if it is to the right then move left. I.e. try to keep the object as best you can in the middle of the screen.
