I wanted to update this thread with some videos I've just added to YouTube.
They're not fancy, so don't expect funky music or titles or anything like that.
The first shows about two minutes of driving, collecting and scoring. We learned pretty quickly that chasing down a single robot and scoring on it was extraordinarily difficult. We expect that it'll become quite easier to find targets to score on when there are more robots on the field. It was also to get a feel for how many balls will be available for collection from the field since our supply was limited and there were no human players.
We broke an encoder early during practice due to some misalignment, so all of this driving was done with half-broken traction control. The right side drive had traction control and the left side did not, so the robot was very hard to control.

The second (eventually) shows off a bit of the rough traction control code and was taken before we broke the encoder. We've opted to make traction control controlled by a joystick button such that it's on only when the driver wants it. As we refine it and make it respond better in turns, we'll turn it on permanently, I expect.
