A. 1. Yes. 2. Please see Q560 .

R25 is meant to deliniate the location of the bumper zone for the purpose of measuring it during inspection. It is not meant to say the the BZ must lways be 2-10 from the floor during play. The BZ is defined in the Robot Section because it is a robot property. It is not an Arena property, as would have to be if it were defined in a fixed relation to the floor. The BZ is defined in relation to the robot and the floor is mentioned only to provide a point from which to measure.

IMO, the Robot rules demand a fixed relationship between the frame, bumper, and BZ. That fixed relationship demands that the BZ's orentation is always the same as the bumpers and frame. The BZ "moves with the robot."

This Q&A entry addresses your question.

A. Yes.

In short:
Q: Do the bumpers need to remain in the bumper zone?
A: Yes

The GDC is not saying here that the bumpers would NOT be in the BZ in this scenerio.

R22 states clearly the purpose of the bumper which is "to protect the frame perimeter" not the undercarriage or the inside of the robot, etc. With this rule in conjunction with R25, it would not seem to make sense not to allow the frame articulation as long as the bumpers continue to perform their one and only stated purpose. Also, if it were deployed as a defensive or offensive move perhaps it should not be allowed, but the end game is different (and autonomous too???)

It is likely not to be allowed given the Q&A precedence already in place but Would these thoughts have made a difference (perhaps they were mentioned in discussion but there is no way to know I guess).

I posted Q&A #559 & #560 after we were together with 2474 at Traverse City. They used tilt for the pyramid shots, and we used tilt for climbing. After seeing how well your shot worked, we were thinking of ways we could do similar things. I had discussed it with the referees at TC, but there wasn't a clear consensus on how the rules would be interpreted. Therefore, I tried to construct a few questions that I thought might settle the issue for us (and anyone else) prior to our next event.

Congratulations on your win at St. Joseph. See you at MSC!

(Edit: 559 & 560 were supposed to be submitted together as one question, but my fat finger hit the enter button at the wrong time and I couldn't find an "edit" function to correct it.)
