We are using the gyro and encoders to do what essentially boils down to proportional velocity controller on top of feed-forwards. In a year where the tire dynamics play such a big part in how the robot responds, having a little bit of feedback to help the driver deal with the fast dynamics of a bouncing robot helps a lot.
We are currently just averaging the angles from the two cameras, but when we get a bit more time, we are going to work on using the pair of cameras to do stereo distance measurement. We have a proof of concept working on a laptop, but haven't made it work reliably yet on a robot.
If I find a student on my team who came through FIRST having learned nothing more then he wanted to go to MIT, I'll give my self a pat on the back and start counting down to kickoff.
