....

I have taken one example, there are many others. All of them, relate directly back to the "turning-physics". If you understand that, you will find 10 ways to solve your problem.

Your next steps should be:
  • Read the whitepaper.
  • If you need help understanding what is in that whitepaper: ask for help understanding it.
I can't over emphasize how much I agree with John's statement. Chris's whitepaper should be required pre-season reading for anyone who's going to be working on a FIRST drivetrain this year. All beliefs and myths about robot turning can be shown or disproved with this paper. Once you read this paper, your design process will be simplified greatly.

In fact, I recommend as an exercise that you try applying these calculations to your 2005 drivetrains. The lessons will sink in much more easily that way.

Basically, read the paper, do some calculations, and you'll learn how to turn.

And they say math isn't fun...
