Those are nice wheels! Care to post some more information? Materials, a drawing or two? Pleeeeeeease? 
Sorry for the confusion that I caused by posting the newer pictures. Discussion of these wheels started a few months ago in this thread.
Holy nice! That is a good looking omni-drive! How much does the base weigh? It looks really sturdy, but the 1/4" plate is heavy…
This chassis was used to illustrate holonomic drive and some other principles (wiring, design for maintainability, etc.) at St. Louis regional Fall training camp. Weight as driven is 69 lb. including battery. I agree that the drivetrain is overbuilt for competition.
For more discussion see this thread.
