Is the top sides of the field perimeter considered to be inside of the Climbing Zone?
For example, is it legal for one or both robots to be pushing with some stand onto the top side of the perimeter wall and
still be able to extend above 18" high plane (obviously, in the last 30 sec of the match)?
still be eligible for the elevation points?
Also, when you say “attach” is it in a sense that you don’t want anybody to mechanically grasp perimeter or in any sense of attachment? (Because, hypothetically, somebody could build a VRC legal electromagnet out of high strength axles and lots of wires and “attach” to a single wall surface).
The left variant would be legal under current reading of <SG14>, but will present slip concern if something doesn’t go according to plan.
The right variant includes an extra red support. While not complaint with <SG14> by letter, it does comply with it by spirit, because it doesn’t grip on the perimeter.
If something goes wrong with the right design, it might still fall inside perimeter, but there is very small chance that it will fall outside.
I didn’t put all the details in the image but, if my guess is correct, this type of setup might be common, and the center of gravity could be high enough to think about the safety concerns.
Edit: Now that I though about it, probably, it is not going to be more of a concerns than some of epic falls in Skyrise.
Edit2: Actually, never mind, I looked at my own picture and realized it is not a concern, all students have to do is to leave some space between red part and the wall. If positioning is precise - it will not touch the wall. If something goes wrong it just will touch the wall, the fall will not occur and they might just lose eligibility for some points.
