# Hypothetical climb scenario

Hello,

I’ve got a hypothetical climb question and I am asking it here because I know Q&A wont respond to a hypothetical. The hypothetical scenario is:

At beginning of endgame, Robot A drives onto scale platform, parks in front of the rung, and drops two large “plates” to the left and right side of itself such that they lay flat on the platform and are tethered to Robot A in some mechanical way. Robots B and C of the same alliance drive up on the plates residing on the platform such that their wheels are no longer in contact with the platform but are exclusively on Robot A’s tethered plates. Robots B and C then raise themselves 1 foot via pneumatic pistons or some other method until their bumpers exceed required climb height. Robot A utilizes a Levitate power up to generate a climb (it can’t hang because it’s tethered plates are still in contact with the platform).

All robots are at a minimum transitively supported by the scale and Robots B and C are not in direct contact with the platform but are supported by A. The plates dropped by A are mechanically tethered. A levitates by Power Up proxy.

Is there any rule or rules that would, in your opinion, disqualify this strategy?

I’m not confident enough to say that it’s legal for sure, but in my opinion, even if it is legal you’ll be hard pressed to find enough teams that could consistently do this. It requires a supporting robot to accomplish so I don’t think many robots would be designed around that kind of “climb” mechanism.

I believe that deploying something under the robot to lift would be illegal because it moves the bumpers out of the bumper zone. Having robot a’s platforms be a ramp that gets b and C’s bumpers 12 in up would work as a climb.

I thought about that but in trying to ascertain it’s legality I found this (see bold):

R24. BUMPERS must be located entirely within the BUMPER ZONE, which is the volume contained between the floor and a virtual horizontal plane 7 in. (~17 cm) above the floor in reference to the ROBOT standing normally on a flat floor. BUMPERS do not have to be parallel to the floor. This measurement is intended to be made as if the ROBOT is resting on a flat floor (without changing the ROBOT configuration), not relative to the height of the ROBOT from the FIELD carpet.
Examples include:
Example 1: A ROBOT that is at an angle while navigating the FIELD has its BUMPERS outside the BUMPER ZONE. If this ROBOT were virtually transposed onto a flat floor, and its BUMPERS are in the BUMPER ZONE, it meets the requirements of R24.
Example 2: A ROBOT deploys a MECHANISM which lifts the BUMPERS outside the BUMPER ZONE (when virtually transposed onto a flat floor). This violates R24.

To be clear does the rule imply “before” a legal change or that a “change” is never permitted?

From what I have seen it would still be illegal because the bumpers came up out of the bumper zone with part of the robot still at almost platform height.

Update 1 stated a new description of CLIMBING

CLIMBING
For each ROBOT fully supported by the SCALE (either directly or transitively) with BUMPERS fully above the BRICKS at T=0, not in direct contact with their PLATFORM, and not at all in the opponent’s PLATFORM ZONE

In your scenario B and C are not in direct contact with their platform rather non-climbing ROBOT A ramp extensions…Check

They are “fully supported by the scale” transitively as Robot A is lending support and they are fully supported by robot A on the platform…Check

Robot B and Robot C BUMPER Zone at below 7.5 " inches (update 2) if the pistons on a flat floor push the bumpers above that as Bumper Zone rules still apply in endgame … Fail

IMO

The tethered plates would have to be the thing that lifts up, due to aformentioned bumper zone rules.
