PLEASE HELP Arduino Uno R3 with CMUCam 5

Im trying to program the Arduino to communicate with the CMUCam 5 over serial, i want it to get the outputs from the camera and track and go to an object, its easy to get the camera to output the location and object as x and y values, i just have no clue as to program the arduino to read those, save them as variables and control motors depending on the variables. Please help.

If you get an arduino to work with a web cam. I'm your hero. Please e-mail me at jakekisiel@smarttechnologiesllc.com, and we just might have something worth talking about.

I got it driving motors, i just need to take the block data that the CMUCam 5 is outputting and translate it into variables, then make a correcting program to find and drive to an object
