Crab here as well. I've posted many tidbits about what we're doing on it in several of the other threads out there. I'm sure the search function can lead you to them.

Hm. Two wheels per module, with a set of miter gears between them?

How is the crab working for you guys anyway? we decided to use 4 wheel drive instead of it, what made you decide to use crab drive?

negative on that, thats simply referred to as "wide drive" style.

Crab drive is where the robot has the ability to rotate its wheel effectively steering them, while having them powered also. There are many different styles of doing this. Do a quick CD-media search for "crab drive" or "swerve drive" and you'll see plenty of examples.
