580: Important Starting Size Clarification


6526D
26-Feb-2020

<G4> Robots begin the Match in the starting volume. At the beginning of a Match, each Robot must be smaller than a volume of 18” (457.2 mm) long by 18” (457.2 mm) wide by 18” (457.2 mm) tall. Using Field Elements, such as the field perimeter wall, to maintain starting size is only acceptable if the Robot would still satisfy the constraints of and pass inspection without the Field Element. Robots in violation of this limit will be removed from the field prior to the start of the Match, at the Head Referee’s discretion.

<R4> Robots must fit in a sizing box. At the beginning of any Match, Robots must be smaller than 18” (457.2 mm) long by 18” (457.2 mm) wide by 18” (457.2 mm) tall.

Q&A 439 https://www.robotevents.com/VRC/2019-2020/QA/439 Q&A 423 https://www.robotevents.com/VRC/2019-2020/QA/423

Although you have answered questions about starting size in the past (see q&a's listed above), we are still a bit confused on the legality of the situations drawn below.

A & B: The robot itself is in size, but the preload is out of 18” (length wise)

C : The robot itself is out of size (height wise because of its tray), while the preload is inside of the robot

We are mainly concerned with this: if you were to put the preload into your robot and by doing so it forces a section of your robot out of the 18"x18"x18" size (as seen in scenario C where the tray was forced outside by the preload), would that be a legal starting position. If you could clarify which starting positions are considered legal that would be very helpful. Thank you! img

Answered by Game Design Committee

First, thank you for quoting the relevant rules, searching for similar Q&A posts, and providing a clarifying image.

A & B: The robot itself is in size, but the preload is out of 18” (length wise)

These would both be legal. These are both scenarios that were intended to be covered by Q&A 439, as linked.

C : The robot itself is out of size (height wise because of its tray), while the preload is inside of the robot

This would not be legal.

Another way to word the response from Q&A 439 would be as follows:

G4 and R4 are intended to refer to Robot size only. The word 'Robot' refers to the VEX definition of 'Robot': "Anything that has passed inspection that a Team places on the field prior to the start of a Match." An inspection-passing Robot consists of VEX metal, wheels, gears, electronics, etc.

The hypothetical Robot C may have passed inspection (and therefore satisfied R4). Once it is placed on the field, the Head Referee is now checking its compliance with G4. Since some portion of the metal, wheels, gears, and electronics that make up the 'Robot' are now outside of the 18" x 18" x 18" size restriction, it is now in violation of G4.
