Re: Two extensions under 14" boundaries

Are Q&A's legal and binding or does it have to be in the rules to make it official?

It seems to me that this is a big deal because Update 4 talks about transitions to/from barriers and bridges being exceptional states.

If your robot is transitioning between one of these is it legal to have bits of the robot extend below the plane defined by the tires?

I would think that this rule should involve actual bumper zone violations not theoretical ones.

Violations occur if and only if you extend something (or somethings -- appendage rules do not apply) below your robot and it moves your robot such that your bumpers are outside the bumper zone (for the surface you are actually on not a theoretical surface you may be placed on).

The barrier/floor transition is a special case. While in contact with the barrier, tilts and such may move your bumpers outside the zone. I think that there is a modified bumper zone (in WORLD Coords, not robot coords) that can be defined near the bumper to make this work.

The bridge/floor should be a case where the bumper zone should be modified to be such that your bumpers must not leave a fixed zone defined by the floor and a bridge coords zone defined by the surface of the bridge.
