I think what she meant by doggie door is that the front flips out during autonomous when tour 10 pt. ball whips are deployed. The reason for this is basically better capacity. We can hold an extra 4 or 5 balls that way. It is also easier to get the balls out of the machine. Once the front out, it remains out for the rest of the match.

As for the whitewalls, they are actually barbecue wheels. the whole top frame of the robot articulates separately from the black part underneath. We raise them to the level of the 6 inch step, and use that to lift up the drive module. I don't think that explination was very clear, so I'll try to get a picture of that, along with the Ball-O-Fier opened up.
