The updated documentation site is now live at
http://robotpy.readthedocs.io/en/latest/ . It cross-links all of the various RobotPy documentation sites and APIs, which should make it easier to find the information that you're looking for.
Try it out, give me feedback, make some pull requests or file some issues.
Source is at

Note that the 'stable' documentation still contains last year's site and won't be upgraded until kickoff.
