Re: 84 inch diameter vertical right cylindrical volume ?
 

The "it" I was referring to was the definition.

Re: 84 inch diameter vertical right cylindrical volume ?
 

I guess someone needs to go read <R10>. With regards to the timeframe, rule <G30-C> would trump the definition of FINALE CONFIGURATION, as it explicitly allows expansion up to said configuration provided the tower is being contacted. Also note the use of "i.e.", which in modern usage usually means something to the effect of "such as" or "that is". It's defining the Finale; the finale configuration is the configuration the robot would take during the Finale; <G30-C> allows expansion up to the limits of the Finale Configuration, provided the tower is contacted.

Re: 84 inch diameter vertical right cylindrical volume ?
 

You are correct, I missed the note on R10, this is the first time they have ever explicitely called out the volume referenced to the ROBOT, my guess is they see a lot of robots flipping over this year.

Re: 84 inch diameter vertical right cylindrical volume ?
 

Sorry, but you lost me... initially Chris is me and Matt C said that so long as your robot fits within those dimensions you are alright, but it sounds like now Matt C is saying that this cylinder is in fact centered on the robot base.

Would the word "right" in the phrase: 84" diameter vertical right cylinder volume, be referring to the fact that it remains perpendicular to the robot base, rather than centered around it? Also if it is so rigidly fixed to the robot, that would disallow extending below the robot base, or would the extension just have to fit inside the 90" height maximum?

Which is correct?

Re: 84 inch diameter vertical right cylindrical volume ?
 

A right cylinder is one where the walls meet the top and bottom at right angles. Think roll of paper towels sitting upright on the kitchen counter.

If the walls of the cylinder are not at 90* to the base of the cylinder, it is not a right cylinder. And the top and bottom would be elipses rather than circles.

The cylinder remains aligned in relation to the robot. If the robot tips over, the invisible cylinder tips over too, so it is laying on its side. This is different than what happened in previous games. For instance in Rack-n-Roll, if you tipped over while you were extending to put a ringer on the top spider leg, you probably violated the size constraints.

The robot does not have to be centered in the cylinder, it just has to fit into it at all times.

Re: 84 inch diameter vertical right cylindrical volume ?
 

Thank alot Gary. But also do you think that the bumpers would have to be included within this 84" maximum? or is it just to the edge of the robot perimeter?

Re: 84 inch diameter vertical right cylindrical volume ?
 

The bumpers are part of the robot for all rules except weight and the 28x38 max frame perimeter.

Edit: I stand corrected, see below. The rule exempts them from all configurations.

Re: 84 inch diameter vertical right cylindrical volume ?
 

(emphasis mine)

Since <R10> defines both NORMAL CONFIGURATION and FINALE CONFIGURATION limits, the bumpers are excluded from both.

Re: 84 inch diameter vertical right cylindrical volume ?
 

I had just missed the note that stated it is in reference to the robot, not the field, meaning that if the robot tips, so does the cylinder. Now I just feel my figure is correct whether the robot shown is upside down, right side up, sideways, or slantways in regard to the field.

Re: 84 inch diameter vertical right cylindrical volume ?
 

alright, thanks for all your help!
