g16. Don’t climb on each other until the end. Unless during the ENDGAME, or attempting to right a
fallen (i.e. tipped over) ALLIANCE partner, ROBOTS may neither fully nor partially strategically
support the weight of partner ROBOTS.
do they expect us to climb in a chain?
yes.
Or, at least, you are permitted to climb in a chain.
These robots must be able to support a lot of weight in order to achieve that…
Has anything like this been done in the past?
You should check out 2010 - FIRST Breakaway.
Is it allowed to extend a mechanism beneath the robot such that it pushes the main frame and bumpers of the robot up to the required height but is still supporting the robot on the ground but not by the rung? In the scoring section, it only scores based off of the bumper height and if the robot is supported by the scale. The platform is part of the scale diagram, so I believe it is counted as part of the scale.
You should review R24.
My team suggested mounting a rung on the back of the robot. That way any robot designed to grab onto the rung would also be able to climb our robot as well.
Okay, thanks.
Could our robot stay on the platform but have a ramp extend over the bumpers so that one alliance partner could drive on top of our robot and therefore be elevated over the bricks? G17 says we can climb on each other in the endgame, and it would be much easier to support that weight on the ground rather than attaching to a robot already off the ground on the rung. The rules say that a climb means that a robot must be “fully supported by the SCALE (either directly or transitively),” and section 3.3 seems to say that the platform is part of the scale. That way the rung is free for one robot to climb, one robot can drive on top of ours for a climb, and levitate could be used so that our robot would get counted as a climb. Three climbs.
You that is possible. My team decided that there were too many unknowns, but if you figured a way around them it would be a solid strategy guaranteeing at least 2 climbs.
this puts me in the mind of the 2007 game. One robot would lift the other two. You can then use Levitate to get the third. Would be a very powerful bot, and the RUNG is never touched.
Same here. We even considered having three (left, right, and back as climbing). If we only drew one up, hitch on the back. If two, do left and right. However, with the levitate power up, likely to only do the one.
Yes, we code named this maneuver Fezzik.
I don’t understand how rule R 24 would apply to this? Could you further explain. What is the difference between a robot climbing the rung and having the entire robot lift 13 in vs having a robot deploy “jacks” and lifting the frame, wheels, bumpers etc vertical 13 inches?
Wouldn’t that be the same?

Something something bumpers higher than the max height from the bottom of the bot if you jack it up…
from the way I read the rules now don’t quote me on specifics but what I assume is it is very similar to 2010 not like strategy wise but in the way climbs occur, so other robots can use your robot to scale up above 12in mark. the methods that can be used this year that other teams can use to hang on another robot such that they are fully supported directly or indirectly by the scale bar I am unsure of, I would have to read further.
my best advice is to look at how climbs worked in 2010 to get an idea and then apply it to this years rule set and overall gameplay strategy.
Your bumpers must remain within 7 inches of the “bottom” of the robot. The way this is articulated is saying if your robot were transposed to a normal standing position, are the bumpers in the bumper zone. If you elevate by means of cylinders or similar from the floor up 13 inches, your bumpers are no longer within the bumper zone.
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
If you look at example 2 on R24, it says that “A ROBOT deploys a MECHANISM which lifts the BUMPERS outside the BUMPER ZONE (when virtually transposed onto a flat floor). This violates R24.”
Table 4-1: FIRST® POWER UPSM rewards
FACE THE BOSS:
All three (3) ALLIANCE ROBOTS have CLIMBED or two (2) ROBOTS have CLIMBED and the ALLIANCE has played the LEVITATE POWER UP
In the glossary, climbing is defined as follows.
CLIMBING:
A ROBOT** fully supported by the SCALE** (either directly or transitively) with BUMPERS fully above the BRICKS at T=0, and not at all in the opponent’s PLATFORM ZONE
So simply being above the line won’t cut it, a robot has to be fully supported by the scale, but then technically you could have a robot on top of you.
Yes.
2007 – done successfully by a number of teams.
2010 – was allowed but wasn’t done by many (any?) teams.
