I've been very impressed with all the multi-ball autos I've seen this year. It certainly has been a very interesting challenge.
As mentioned above, team 4488 Shockwave has 1-ball hot, 2-ball hot, 2-ball non-hot, and 3-ball non-hot modes. I'm very proud of our programming students for pulling this off. They played around with lots of cool stuff in the preseason such as vision tracking and using a gyro for alignment (go back to straight even when kicked or bumped, press a button to turn 90 degrees, etc.). They applied a lot of this to our autonomous this year. The drive team can select what goal to shoot at via a Kinect at the driver station or during the 1-ball routine trigger the fire. During auto the robot uses a gyro and drive encoder to guarantee drive distance and orientation. The video link that SciBorg Dave provided above is a great example of the system in action.

Also, 4061's robot is an amazing work of engineering. Such a cool design. We're excited to go to St. Louis next week and look forward to seeing you guys and so many other great teams competing!
