The
1640 - Sab-BOT-agewiki is a Mediawiki site hosted at GoDaddy.
They have a mini-blog off of each year's build,
2013 game and then links from that page to all the subsystems. The wiki was started in 2009 and has all of the details of each robot.
They do a great job of putting their designs up as they happen. The last few years have been pivot drive based, for example this is the info from the
2013 pivot drive.
From a tech standpoint, I like MediaWiki. There are a ton of plugins to make it easy to manage and maintain different content types and info. The PHP code needed to set it up is pretty minor. Most of the bigger hosting sites have auto installs of Mediawiki.
