Edit: Beaten to it.

Or use the camera so location is never an issue. Encoders and gyros require correct orientation of the robot from the start. This year there is nothing to square your robot against. For this game, I think that a compass may be helpful to zero the gyro at the start. Then encoders should be sufficient for driving straight for a certain distance.
