[3] And I may be fine with people putting whatever they want ON their pizza I am NOT ok with people making their pizza that thick. It's an abomination!

I'll accept Zebracorn Cheesecake without further comment but don't be hatin' on Chicago Style Pizza or I'm come after you.

Chicago Style Pizza is not just a thing, it is a thing near and dear to my heart.

Chicago style pizza is so deep and rich, you could sink a harpoon in it!

Would the attached robot be legal?

The frame parimeter is <120" and every external corner of the frame perimeter has at least 8" of bumper protecting it. Seems like it would be legal to me.

I can see adding 4 omniwheels, a battery and the rest of the electronics and doing tolerably well in St. Louis with such a robot. You could make this from completely COTS material (some plywood, some 2 by 4s, and some deck screws and that's about it) in the pits in St. Louis in about 2 hours tops, including the bumper but you could actually make the bumper before you arrive because bumpers don't have to go into the bag...

I am not saying this would be a world beater but I am saying that 20-30% of teams might do better on average with this robot than the one they currently are planning on using in St. Louis.

An interesting thought experiment on a sort of Zebracorn Self Cheesecaking concept.

Fair warning to anyone attempting this, don't be caught with more than one object that resembles a robot built to play stronghold to a reasonably astute observer. A team is permitted to access but one such object at an event.

I'd like to see someone drive that either over a defense or over the secret passage way.

The low bar and berms wouldn't be too big a problem; there's no need for the chassis to be that low to the floor. It would be best if the robot had a holonomic (or swerve) drive system so that it can drive along its short axis onto/off of its own batter and along its long axis to cross under the low bar and over the berms. I'd probably go (non equilateral) kiwi.

Oh man if only they had thought about that. Oh wait...

The robot has 3 wheel kiwi drive, that allows it to go over the secret passage, and go sideways under the low bar to come back and capture.

I see no reason why that configuration would be illegal. Of course how you use it involves a different set of rules.

they might do better...but still be useless on an eliminations alliance.

This is an interesting idea. But let's say I'm right, and that some 20% would do better with this robot. Who's to say that some of that 20% might not get a break here and a favorable ally there and BOOM DONE! all of a sudden they're a drafting team.

For that team, they probably wouldn't have been drafted at all and now they are not only playing after lunch, their an alliance captain. That seems like an upgrade to my kids' St. Louis Experience. I don't know how I'd tell my kids no if they wanted to give it a shot.

Also, if this strategy was used against me, I'd instruct my driver to pin the offending robot at 30 seconds left in the match and then back off, and when the offending robot chases me, pin it again ... since it can only drive in one direction to extract itself. This will allow 3 automatic scales as the alliance tries to take the batter.

one small issue here... you yourself will not only receive G22 but also G11. please don't leave parts of the rules out to fit your argument the way you choose. you don't have to have contact to constitute a pin read the blue box for G22. By pinning someone in there own courtyard, yes what you would be doing is a pin, you would also be looking to get them the foul of contact in the last 20 seconds thus G11 could be called on you.

G22 ROBOTS may not pin an opponent’s ROBOT for more than five (5) seconds. A ROBOT will be
considered pinned until the ROBOTS have separated by at least six (6) feet. The pinning ROBOT(s)
must then wait for at least three (3) seconds before attempting to pin the same ROBOT again.
Pinning is transitory through other objects. If the pinned ROBOT chases the pinning ROBOT upon
retreat, the pinning ROBOT will not be penalized, and the pin will be considered complete.
Violation: FOUL. For every five (5) seconds in which the situation is not corrected, FOUL. If
extended and egregious, RED CARD
There is no FIRST Robotics Competition specific definition of pin, so a
general definition applies; “to prevent or stop something from moving.”
As a result, contact is not required for pinning to occur. For example, a
ROBOT parked right behind an opponent that is on the BATTER could
be considered pinning because the dividers on the BATTER and the
parked ROBOT prevent the opponent from moving.
Generally, pins that exceed fifteen (15) seconds are considered
extended and egregious, regardless of a pinning ROBOT’s mobility,
however circumstances vary and the assesment is open to REFEREE
discretion.

The intent isn't to draw penalties, but to keep the opponent in your courtyard so they cannot get back on their batter for the capture in time. I'd be surprised if G11 was called in that situation unless it was overly obvious that you went out of your way to contact them.

[rich2202]

IMHO, given the 20 second rule, that is a nuance that will be lost on most refs.

[rick.oliver]

I don't understand how this robot design and the strategy of stopping low goal scoring meets the definition of a Choke-hold.

A choke-hold strategy is one, when executed effectively, guarantees a win, regardless of what the opposition does.

[IronicDeadBird]

You blocked points from goals but can't you still get points from sweeping and puppy guarding the secret passage?
