Would the low amount of friction on the wheels allow
the robot to move like an omni-drive?

I don't know how slick the flooring is because I was not able to attend a Kick-off.
But from what I have heard, it sounds pretty slippery.
Any guesses on how well this would work?

Edit: Hachiban beat me to it!
We tested that theory, granted we were on a smooth tile instead of the flooring, and found that without the ability to guarantee that all the wheels are on the floor with the same pressure. Otherwise the robot will veer uncontrolably depending on which wheels are in contact.
