Re: Swerve Drive vs Mecanum Wheel drive?

Optimizing mecanum material selection and mechanical design isn't done at all. Just increasing robustness while decreasing weight would go a long way toward making mecanum wheels better for FRC team use.
It's been a while, but I'll reply anyway...

While it's true that you can make improvements like these, they are more design solutions and optimizations rather than conceptual changes. A mecanum wheel, no matter how well deisgned, will still be just that: a mecanum wheel. Rollers tilted at 45* angles on a wheel. There can't be any kind of mecanum revolution unless somebody figures out how to lock the rollers without wasting weight.
This is not a bad thing, as optimization is a very good thing and makes good ideas better, but it does show inherent limitations in mecanums. Other kinds of drives can be done in many different ways by comparison.
