84 inch diameter vertical right cylindrical volume ?
 

Does this not make sense to anyone else?

The Finale configuration confuses me. Does this just mean we have to fit in a 90 inch tall by 84 inch diameter cylinder? Or a sphere? If we are tipped does the cylinder rotate?

I've read the manual.

When the last 20 seconds of the game are in effect, you cant be outside that size cylinder.
If you get tipped you wont recieve penaltys for being too big.

Take a soda can. Barring stuff around the base and top, it is a vertical right cylindrical volume. (You could also wrap paper around that can for a better impression.) Now expand it to 90" high and an 84" diameter. Fit in it.

As for the question on tipping, I can't find anything saying tipped robots are penalized for going out of their volume. I also can't find anything the other way. Q&A it and see.

Re: 84 inch diameter vertical right cylindrical volume ?
 

it is slightly confusing, but the cylinder is defined using the robot's coordinate system (flips over with the robot), even thought the cylinder itself is called a 'vertical' right cylindrical volume.

(specifically <R10> During the MATCH, the ROBOT will assume one of two operating configurations. When in each configuration, the ROBOT shall fit within the limits shown below (note: these limits are defined in reference to the ROBOT, not the FIELD). (emphasis mine))

Re: 84 inch diameter vertical right cylindrical volume ?
 

So, does this mean that the final configuration must fit inside a 84" diameter cylinder oriented to the robot's orientation, no more than 90" tall? Or is the 90" height separate from the cylinder which would then vary in height depending on the angle of the cylinder?

Seems like awful wording to me.

Re: 84 inch diameter vertical right cylindrical volume ?
 

The height is of the cylinder. The height of the box is not separate from the box base (normal configuration). The way it works is with orientation to the robot. Therefore, should the robot tip completely onto one side, it is now in a horizontal right cylinder with a 90" length and an 84" diameter.

Re: 84 inch diameter vertical right cylindrical volume ?
 

the cylinder is always 84" diameter, always 90" tall, the end surfaces are always a circle (no angles involved) and all dimensions are aligned with the robot.

If your robot leans at a 10 degree angle while hanging from the tower, so does your reference cylinder.

Again with the soda can - take said soda can and bolt it to your robot such that it is sitting normally (like on a table) when your robot is on the ground. The reference cylinder is always aligned with the soda can. your robot does not need to be centered in the cylinder, just inside it.

Re: 84 inch diameter vertical right cylindrical volume ?
 

I have a question about the placement of this cylinder relative to the robot. I have read through the rules a couple of times, and couldnt find anything to answer my question. What I am wondering is if this cylinder has to be centered relative to the robot base (meaning you have only 42" in all directions to expand), or whether the only requirement is that your robot must fit inside an 84" diameter cylinder (meaning you could expand 84" on one side, but not the other. Any insight or clarification is greatly appreciated.

Thank you,

Previous year cylinder rules did not have it centered in the robot base, and nothing in the rules indicates this isn't the case this year.

Re: 84 inch diameter vertical right cylindrical volume ?
 

This year, the FINALE CONFIGURATION appears to be similar to the cylinder limit of 2008, which stated "While in the PLAYING CONFIGURATION, the ROBOT may expand up to a maximum horizontal dimension of 80 inches(e.g. all parts of the ROBOT must fit within an imaginary 80-inch-diameter upright cylinder)." (NOTE: This is a rule from the 2008 game that I am merely including for reference)

NOTE: I'll include a disclaimer that this is my interpretation of the current FINALE CONFIGURATION (rule <R10>), and the drawing is not to scale (best I could do in a short time in MS Paint).

Re: 84 inch diameter vertical right cylindrical volume ?
 

The rule states it is a "vertical right cylinder", therefore it would not move with the robot, but is stationary. Rule <G30> allows for righting of your robot by allowing them to "expand up to the FINALE CONFIGURATION volume while, and only while, performing the righting operation."

Re: 84 inch diameter vertical right cylindrical volume ?
 

During the last 20 seconds of the game, but also during the rest of the game if your robot is in contact with the TOWER. So you can get a head start if you need more than 20 seconds, is my guess.

Re: 84 inch diameter vertical right cylindrical volume ?
 

Which of course is contradicted by the FINALE CONFIGURATION definition in 8.2, but I'm sure it will be amended in the first revision in Update #1. (There is an advantage to having a few thousand proof-readers checking your first release document)

Re: 84 inch diameter vertical right cylindrical volume ?
 

They're mentioned in the same rule. I honestly don't think the GDC could overlook something like that. You don't have to be touching the tower in the last 20 seconds, you do before that.

Re: 84 inch diameter vertical right cylindrical volume ?
 

yup, read <G30> in it's entirety a few times....
