Thanks! Your robot looks pretty nice as well. Hopefully we'll get some chances to play with y'all in Portland and Seattle.

The hopper can hold 20 balls. Our testing shows that the number of balls that make it into a trailer depends almost entirely on our distance from the trailer. Maybe saying as much is obvious, but it really makes a big difference. In ideal conditions, 95% of the balls make it in and the accuracy drops from there as the distance increases.

I have some video taken at the practice field that shows us chasing around an older robot and scoring on it as well as some that demonstrate our traction control algorithm. I'll try to upload those to our YouTube account tonight -- but some of them are pretty uneventful and boring.
