What's the full weight of the unit (with swerve)? And what leads you to believe the ball system will be lighter than using wheel?

Do you propose that the system will begin slipping between the ball and the rollers or between the ball and the floor? (Why?) I think Brandon and I are both stuck on how aligning the rollers increases this threshold vis a vis a system that doesn't use a frictional drive for steering (i.e. a belt, chain or gear swerve).

And listen to Jesse; you really want to talk to Aren.


Tom: secret's out. OP should probably edit the original post.
