It is curious that a robot can pass inspection but not be able to legally start a match. If your robot is an 11 by 20 by 15" prism, it will pass inspection, but it will not be able to start a match because it will need a “wall” shaped hole on the side of the robot. I suppose a really good inspection box would include a cut out wall section on the bottom to verify that it could actual start a match, but that would make inspection unnecessarily difficult.
Yep, only 19" can touch the ground
