Not having any chain is a part of it. Removing the chain also makes the modules much shorter, which decreases the side loads on the axels. This eliminates the need for a delrin bearing at the bottom of each module.

That’s why I want to make them narrower. My reasoning is that if I make them narrow enough (say 3") I won't have to do any dragging at all - It'll be just like having four wheels - but with a groove in the middle of each one!
