This amazing autonomous robot tracks and follows an RC copter

A team of undergraduate computer science students completed their final project for their CSE 190 class, taught by alum Chris Barngrover: an autonomous robot that follows a remote-controlled helicopter around.
They started off with a TurtleBot, a low cost personal robot kit equipped with open source software. The robot includes a Kinect and a netbook. Students used the open-source Robot Operating Software to program its tasks.
The students are: Frank Bogart, Mike Lara, James Lee and Kenny Yokoyama. 
We're impressed with the results!
