As per R3:

"The ROBOT must be able to be arranged into a TRANSPORT CONFIGURATION with dimensions which do not exceed 28 in wide, 42 in long, and 78 in tall"

This means that there are no specific rules for the frame dimensions, but it is unlikely that you will be able to reduce the size of your frame in under a minute so the frame limitations would likely be 28 in by 48 in. (Although technically, you might be able to tilt the robot on it's side for transportation. It depends on if the coordinate system of the "28 in wide, 42 in long, and 78 in tall" is relative to the floor or to the robot's orientation. I would strongly encourage you to check in the Q &A forum before running with this idea)

There are no rules during the competition that say how far away from the frame area that a mechanism can extend in the match. Once again, I would be sure though that whatever mechanisms you build will be able to fold up to fit into the
