Im assuming your pan/tilt uses servos, right?

Look around for something called a servo controller.
(such as here http://www.pololu.com/products/elec.html#servcon)

Then you would need your visual basic program to send the proper commands to the servo controller out your serial port:

There are USB methods too, but will probably be harder:

Yea, i ended up using Roborealm to do image processing. I took an example for the logitech orbit online and played around with it. Its really cool now. The camera follows a certain color object around and then the robot begins to follow the object around.

Thanks steve
