Awesome work guys! That back mechanism is pretty sweet.

5254 was discussing similar hanging ideas and this is the part we got caught up on and ended up tabling the conversation until a Q&A clarification.

We were questioning the same rule extrapolation:

R3 The ROBOT must satisfy the following size constraints:

B. must not extend greater than 15 in. beyond the FRAME PERIMETER (see Figure 4-2 for examples) (see G18)

R2 The ROBOT must have a FRAME PERIMETER, contained within the BUMPER ZONE, that is comprised of fixed, non-articulated structural elements of the ROBOT. Minor protrusions no greater than ¼ in. such as bolt heads, fastener ends, and rivets are not considered part of the FRAME PERIMETER.

R22 BUMPERS must be located entirely within the BUMPER ZONE, which is the volume contained between two virtual horizontal planes, 4 in. above the floor and 12 in. above the floor, in reference to the ROBOT standing normally on a flat floor. BUMPERS do not have to be parallel to the floor.

As they are currently written it seems that if your robot tilts 90 degrees, your 15" extension limit also does, which would make it pretty tricky to climb if your robot loses 'normal' standing orientation.
