[SG2] Once the Match begins, Robots may expand, but no horizontal dimension may exceed 36” (914.4 mm) at any point during the Match I have some questions on how this rule is written. it says "No horizontal dimension may exceed 36” " Is this the expansion or the robot itself (assuming the robo…

How i understood the rule is that the expansion limit is a cylinder (due to the unlimited vertical expansion) of 36" diameter. If, at any point, your robot cannot fit in this 36" diameter cylinder, then you will be out of size. Assuming this, your diagram 1 would be the most correct, however that di…

All are illegal as the farthest horizontal point to point is over 36". We take a sizing tool with 36" length and check the robot…

During inspection, I would take the sizing tool fully expanded (36") and see if there is any way to touch both ends to your robot while it is in any reasonable configuration.

This post gives a good explanation: [image] Clarification on <SG2> VRC > Tipping Point (21/22) Also tagging @kmmohn . That’s not what the rule says. Let’s take a look at the rule again: Once the Match begins, Robots may expand, but no horizontal dimension can exceed 36”…

Yup, the cylinder explanation is the easiest to think about (in my experience). Another thing to add is that this 36" cylinder will always have its base parallel to the ground. This is effective even while climbing, So, no matter your robot orientation, the horizontal profile of your robot relative …

[image] Bean: Yup, the cylinder explanation is the easiest to think about (in my experience). This is simply wrong. Read the post I linked above.

Horizontal expansion is absolutely NOT a 36" cylinder. Please read the thread @9MotorGang linked above. The 36" is measured with a tool that checks for any two points on the robot being >36" apart when measured parallel to the floor. Again, not a 36" cylinder.

Whoops, I didn’t even consider that. My mistake. But make sure to measure relative to the field floor now. I think in Tipping Point it may have been robot-relative, but now its field relative.
