Re: my team needs crab/swerve pod cad files
Hi Will,

Good idea taking a crack at a Swerve drive during the off-season, there is a lot of development involved in something like this.

I don't have Inventor, we do our modeling in SolidWorks. Check the attached ZIP file for a STEP assembly of the Robowranglers 148 - 2008 Coaxial Swerve Module. (The STEP file should import cleanly into Inventor.)

This module was heavily inspired by the Thunderchicken 217 - 2002 & 2003 designs. (Thanks Foof!)

Let me know if you have any questions.
I'm happy to help, and always sympathetic toward a college FIRST team!

Regards,
John

PS - All the dimensions are valid; this is exactly as we built her.

PPS - Don't do a swerve drive for a competition robot.
