Hope that clears things up

Wow. I once spent a long time designing a drive just like this. I have to say, this is a very good design!

I gave up on my design because I was worried about turning the modules. The very closest I was able to move the wheels was 4" wide. The effectiveness of a swerve is limited by how fast the modules can be rotated, and with only the window motors for rotation I figured this might be difficult with such wide wheels.

My next and final swerve design was a 45* module like in the 1625 teaser. In the end, this design wound up being more complicated to make then a conventional module and was only slightly smaller so I abandoned this too.

Its cool seeing all the new swerve designs on CD. I wonder how many teams will use swerve next year...
