For those of you who are writing python code for FRC, and you're starting to do preseason stuff, definitely check out the latest version of pyfrc. The robot simulator can now show your robot on a 2D field, which is super useful for experimenting with various autonomous modes. pyfrc can be found on github at
https://github.com/robotpy/pyfrc.
I've been cleaning up the documentation a lot, and there's now a documentation site at
http://pyfrc.readthedocs.org/en/latest/. Let me know if you run into issues getting started, and I'll try to update the docs.
