Hey all-
Team 2220 implemented this at the Central Illinois Regional when Team 4009 DNA told us about a super useful tool they wrote to code autonomous programs. They had their robot programmed in Python, so we spent the night transferring the code into Java and making it work with our setup.

Here's the gist: you press a button in teleop while you're practicing that records any motions you make into a .csv file stored on the roboRio. Then during autonomous, you have it read back that file, outputting the exact same values to your motors/other things. Easy to setup, create, and change autonomous programs quickly and without a lot of planning.
Thoughts/improvements? Big thanks to Team 4009 for the idea and their code in python (you can find the link to their code in the github readme)
It's a hunch, based on engineering intuition; there are too many hard-to-quantify variables to do any accurate calculations. Looking for some experimental corroboration or refutation. - Ether [more]
