I don't know. I'm assuming that the rollers have to point to the center of the robot, and if they're oriented at a 45 degree angle, so they would have to be in a square. But we've never tried, so we don't know for sure. None of the reports we've read seemed to indicate that this is the case, but many of our team members were pretty certain.

Thanks for the replies. Good to know.
