Re: paper: Optimization and Analysis of Drivetrain Movement

I really like that sprint-distance analysis is getting more 'light' in FRC. It's a way better metric for drivetrain performance than '81% adjusted speed' that a lot of CDers throw out during discussions.

To avoid differential equations, I've solved the physics equations in Excel iteratively (with a time-step of e.g. 0.01s and each slice of time on a new line). then I can also plot the curve of all of the variables in Excel. This is also easier to distribute to students in FRC.

What you don't go into detail on is how you determine what the sprint-distance you analyze to is. This all comes down to robot strategy, but it's really *really* important to get this right when you analyze the gear ratios in this way. It's all too easy to say the distance is 27' or 50' when really 10' or 15' is more appropriate for the game.
