Robot exceeds frame perimeter

Where the "no other part" references the appendage in part D. In other terms, you can have one appendage which may extend no more than 14 in. beyond the frame perimeter out at any one time.

If you have two appendages, they can't both be out at the same time, even if they are less than 7 inches out (summing to be less than 14 in.).

and of course the horizontal distance from the front of the fender to the front of the rim is 14.25''... plus the width of your bumper... so it looks like there's no dunking.

[Sean M]

Or at least no direct dunking, but you can most definitely close the gap to within about 3 inches...the trouble would be having others bump into you.

So does this include the height dimensions? Meaning that the maximum height is really 74 inches in the alliance station and 98 elsewhere on the court?

[Sean M]

The maximum height is 60" to start [R02], but may extend to 84" tall once the match starts (as long as your robot is not on your opposing alliance's half of the court), [G20].

The 14" is for being OUTSIDE your Frame Perimeter and it's vertical projection.

What that rule is for is mushroom bots my team had to add on to our frame last year becauseour gear guard stuck out past our frame. Appendages can only stick out14inches though.they just don't want a robot with stuff sticking outside the frame causing a safety hazard

I'm sorry, what do you mean? What rule?

And yes, we covered this (in the aforementioned rules).

I mean the rule the question was first about RO2

[Sean M]

Hmm. I see. [G21] also states that only one appendage may be deployed at any time. But good point.

Hi! In the rule G20, they say: ''Robots in contact with the carpet on their Alliance Station end of the Court are limited to 60 in tall. Otherwise, Robots are limited to 84 in tall.'' and so, what place do they mean when they talking about the carpet on they Alliance Station end of the court.

Thank!

P.S.: I'm not talking in english so sorry if there is mistakes!

[Ninja_Bait]

It means that the robot cannot be above 5' when it is on the half of the court closest to its alliance station, but can be up to 7' on the other half.

Basically, you have to be short when you're defensive, but you can be tall when you're offensive.

For anyone still confused about the description "mushroom bot", it refers to a robot that's designed to have a drivebase smaller than the maximum legal size but have parts above the base extending out to the maximum allowed dimensions. It was a phrase used the first year bumpers were mandatory, as an example of something that didn't obey the rules. The primary intent of the bumpers is to have only bumper-to-bumper contact between robots.

(1) Can we have two arms to push down the bridge, especially if another robot is on it already, for stability reasons? (2) what if a drive shaft links the two arms - would that count as ONE appendage - as it is one mechanism.

I wonder?

I would say as long as one shaft, or gears and chains connecting multiple shafts is driving both, I'd say it's one appendage.

But you don't count. Remember, CD is not official so what someone says here is not the rule. For official clarification you must submit a question to FIRST on the official Q&A site.
