On full field runs, our gear ratio worked as we wanted it to. To go along with all of this, we had a control scheme (known as Cheesy Drive) that allowed us to control the robot remarkably well at high speed. Our problem was misreading the game slightly, where full field runs weren't as necessary as we thought they may be. Knowing what we know now, we wouldn't have shot for such a high speed.

What is this cheesy drive you speak of?

Check out the drive code in this: http://www.chiefdelphi.com/media/papers/2397. For more information, talk to Austin, Tom or Kiet would be your best bet.

Sorry, I'm not a programmer so I don't have the software to view it (CAD actually takes up most of my computer) but i will have one of my guys look at it and explain it to me, but thanks for sharing!!

You have the software to view it, the type of code they (and most of industry) uses is just text.

The code definitely makes a huge difference. The drive code in that paper ran on 2 of the robots on the winning alliance last year. It helps make a 16 fps robot controllable and fluid.
