Ok, so I have a friend who can fit inside 18x18 pretty easily. So if I bring him to a competition for tower takeover and just put him on a judges table, would it be legal?

As much as I would love to see that, there are a number of rules prohibiting it. Most notably your friend needs to have a robot brain and be made of vex components.

I love how your pictures spell AI on the home screen.
Since your friend only fits in a 2d plane, not a robot… must be 3d 18"x18"x18 "
Build better friends!

An 18"x18" square still fits into an 18"x18"x18" cube

your friend is still flat… unless your friend is flat Stanley, flat friends are as useful as dividing 0 by 0… just ask Siri…

The rules state that: “Any parts which are identical to legal VEX parts are permitted.” and they do sell VEXBros…

So I would argue that this is an identical part as VEXBRO or VEXDRO, making your 2d freind legal.

Correct, but that’s were the loop hole is. You are not allowed to use VEXPro components: " ONLY using official VEX EDR components", which you don’t, but then when it comes to identical parts it only says “official VEX component” meaning including VEXPro.
Rules
Robots are built from the VEX EDR system. Robots may be built ONLY using official VEX EDR components, unless otherwise specifically noted within these rules. Teams are responsible for providing documentation proving a part’s legality in the event of a question. Examples of documentation include receipts, part numbers, official VEX websites, or other printed documentation
Any parts which are identical to legal VEX parts are permitted. For the purposes of this rule, products which are identical in all ways except for color are permissible. It is up to inspectors to determine whether a component is “identical” to an official VEX component.

The question is now… can we ask this on the official Q&A?
My team will just pick some 3rd grader and duct-take a V5 brain to their back, should be legal, right? 
Edit: The “identical parts” rule specifies legal VEX parts only… pretty sure VEXBro is not legal for VRC…

Has anybody actually bought a VEXbro?
Yes, definitely.
I don’t think so, but I really want to know what they will do if you buy one.
Also it let’s you proceed to check out…
Also the loop hole I brought up, could that actually be exploited in a more reasonable manner?

would they be alright waiting on the field for as long as it takes to start the match? Will your robot be able to stay in starting size for that entire time?
I explained the loophole above. When talking about identical parts it only has to be a vex product which VEXBRO is. It is a VEXPro product which makes it a vex product.

If you could convince the inspector that the human “is strictly used as a color filter of a color marker for a VEX light sensor”…
But the rule clearly says “Any parts which are identical to legal VEX parts are permitted” which means that the part it’s identical to has to be otherwise legal. As VEX bro isn’t legal, something identical to vex bro also isn’t.

UGH NO NO NO!!!
<R5> Robots are built from the VEX EDR system. Robots may be built ONLY using official VEX EDR components, unless otherwise specifically noted within these rules.

a. Products from the VEXpro, VEX IQ, or VEX Robotics by HEXBUG product line cannot be used for Robot construction, unless specifically allowed by a clause of <R7>
Sorry to quote Game Manual – pretty sure the subsection a was not visible on the version of VEXHub you were using, or you have a visual impairment that was not accommodated for… sorry…
It say…
Any parts which are identical to legal VEX parts are permitted.
It says legal vex part, which doesn’t have to mean
legal for edr? Also then it says…
It is up to inspectors to determine whether a component is “identical” to an official VEX component.
They didn’t include legal this time…
It is all quite ambitious.
