[quote=joeweber;902964]The Mechanum wheels are driven, the chains drive sprokets on the ball differential, between the sprockets are steel balls that are inside a round flange with holes for the balls. The flange is attached to the drive shaft with the omni wheels. Pictures are on our wesite http://www.team1322.org/ideas.htm

I think I know the source of my confustion. I assumed the omni wheels could move independent of each other. Now that I see your ball differential drawing and photos it looks like they are attached to the same shaft so must move together. If this is true, why do you have 2 omni wheels at each location, why not just one?
As always, thanks and good luck!

It provides a smoother ride than having one single omni at each point. A number of teams have tried single; I believe most of them switched to double at some point.
