From the OC Register:
Students at UC Irvine built an app that runs a robot car using an Android phone as its brain and eyes and can autonomously follow a moving object or vehicle. The second-year students - Kevin Jonaitis, Kyle Boos and Joshua Ferguson - coded an app and put it on a Samsung Galaxy S II which is placed in a holder on top of a remote-control car. The phone's camera functions as an eye, and they've programmed it to be on the lookout for the color green.
