Ultimate Ascent Rules quiz

[engunneer]

FRC team 23 is happy to present a rules quiz that you can use for testing your students. FRC 23 requires a 70% or better score from all students to participate in design.

Results can be emailed directly to the student and an optional second email (instructor/mentor email)

If you have issues with the questions, or ideas for new ones, send me an email or a PM. (email preferred)

I got 80%.

It will be interesting seeing how the rest of my team does on this. haha
Thanks for making this and getting it out there, especially on the first day! :)

[CLandrum3081]

70%. Just passed. Pretty good for 11:14 PM. (See what I did there? 1114? Heh...)

[Joon Park]

I got an 80% as well, and ashamed of it. Better study up on my rules more. But for day 1, I guess that's not too bad.

[ratdude747]

85%

Not too bad... I wonder how much of it will change during the season due to updates (like the direct hang question, that one is debatable pending Q/A clarification)

[Racer26]

I got a 90%. Missed BUMPER ZONE, and starting height. Pretty good.

[JosephC]

80%; made a couple stupid mistakes(like only counting white disks in the last question).

As per Glossary Term from Section 6.11 (http://frc-manual.usfirst.org/viewItem/3#6)


PYRAMID: the Red or Blue steel structure on which ROBOTS CLIMB for points.


in conjunction with the diagram from Section 2.2.52 (http://frc-manual.usfirst.org/viewItem/179#2.2.5),

http://frc-manual.usfirst.org/upload/images/2013/1/Figure2-7.jpg
,

in conjunction with the text from Section 2.2.52 (http://frc-manual.usfirst.org/viewItem/179#2.2.5) that states that there is a RUNG1 (http://frc-manual.usfirst.org/viewItem/3#6) located at 90",

The rungs are located 30 in., 60 in., and 90 in. off of the floor. At the top of the PYRAMID is the PYRAMID GOAL, detailed in Section 2.2.4[sic] The GOALS.
,

in conjunction with the text found in Section 2.2.3 The GOALS3 (http://frc-manual.usfirst.org/viewItem/179#2.2.3)

Located atop each PYRAMID is a PYRAMID GOAL. The PYRAMID GOAL is a polycarbonate and metal framed “basket” that is a 23 5/8 in. square that is 2 3/4 in. deep. Rising out of the center of the PYRAMID GOAL is a 20 in. tall, 1 1/2 in. diameter post. Hanging from the top of the post are chains (Ace Hardware P/N: 5365283) to help dampen the DISCS as they enter the PYRAMID GOAL.
,
implies that the PYRAMID GOAL1 (http://frc-manual.usfirst.org/viewItem/3#6), which is only 2 3/4 in. deep, which sits directly on top of the PYRAMID1 (http://frc-manual.usfirst.org/viewItem/3#6), begins at a height higher than 90" (by the diagram above), implying that the PYRAMID1 (http://frc-manual.usfirst.org/viewItem/3#6) itself, in fact extends higher than the top RUNG1 (http://frc-manual.usfirst.org/viewItem/3#6).

It appears that the height of the PYRAMID is not 90", but something in fact taller. Unfortunately, there appears that there are several different direct (factual) interpretations of what this might be.

According to the drawing GE-130174 (http://www.usfirst.org/sites/default/files/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2013/2013_Game_Specific_Drawings.pdf), the PYRAMID includes the PYRAMID cap, which according to drawing GE-130184 (http://www.usfirst.org/sites/default/files/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2013/2013_Game_Specific_Drawings.pdf) includes the Center tube part GE-13018-03, which appears to be the tallest part of the PYRAMID assembly. Let's call the total height of the PYRAMID in this case (which would includes the PYRAMID base, which is technically below the covering carpet, so would measure slightly shorter on a field measuring from the carpet, even though the actual PYRAMID itself would be the thickness of carpet PLUS the thickness of the base thicker) X (which is a value larger than 90", but smaller than 120").

Looking at drawing GE-130434 (http://www.usfirst.org/sites/default/files/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2013/2013_Game_Specific_Drawings.pdf) in conjunction with it's subassemblies, we can ascertain that the 2 3/4" PYRAMID GOAL1 (http://frc-manual.usfirst.org/viewItem/3#6) outlined in the earlier text found in Section 2.2.3 The GOALS3 (http://frc-manual.usfirst.org/viewItem/179#2.2.3) is defined by the plastic side subassemblies found in GE-130414 (http://www.usfirst.org/sites/default/files/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2013/2013_Game_Specific_Drawings.pdf) and bottoms found in GE-130424 (http://www.usfirst.org/sites/default/files/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2013/2013_Game_Specific_Drawings.pdf) and GE-130844 (http://www.usfirst.org/sites/default/files/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2013/2013_Game_Specific_Drawings.pdf).

The discrepancy comes in the following form:
According to the text found in Section 2.2.3 The GOALS3 (http://frc-manual.usfirst.org/viewItem/179#2.2.3)
Rising out of the center of the PYRAMID GOAL is a 20 in. tall, 1 1/2 in. diameter post. Hanging from the top of the post are chains (Ace Hardware P/N: 5365283) to help dampen the DISCS as they enter the PYRAMID GOAL.
implies that the post and chain assembly are NOT part of the PYRAMID GOAL. That means one of the following may be true, with no current way to identify which is true.

The post and chain assembly are part of the PYRAMID, making the PYRAMID height X (as defined before) plus the height of the post plus chain assembly, minus the overlap on the Center tube part GE-13018-03 with the post (approximately 120" according to the diagram shown above). In this case, Section 2.2.52 (http://frc-manual.usfirst.org/viewItem/179#2.2.5) is violated, as the PYRAMID GOAL is not sitting 'at the top' of the PYRAMID, but is instead defined within the PYRAMID structure.
The PYRAMID GOAL sits atop the PYRAMID as per Section 2.2.52 (http://frc-manual.usfirst.org/viewItem/179#2.2.5), the post and chain assembly are not part of either definition, and where the 'basket' as part of the PYRAMID GOAL is defined to include the Center tube part GE-13018-03, in addition to a portion of PYRAMID Cap, specifically portions of the subassemblies GE-13018-02 and GE13018-04 as defined by the plane of the plastic bottom of the PYRAMID GOAL pieces GE-13042 and GE-13084. This definition would be in violation of the drawing GE-13017 which is titled 'Pyramid' which lists GE-13018 (the Pyramid Cap) as a subassembly in it's entirety, and therefore in violation of Section 2.15 (http://frc-manual.usfirst.org/viewItem/179#2.1)

Note: These illustrations are for a general visual understanding of the ULTIMATE ASCENTSM ARENA only. Please refer to the 2013 Official FIRST Field Drawings & Models for exact dimensions and construction details.
In this case, the PYRAMID height would be X minus the height of the Center tube part GE-13018-03, minus a portion of the height of GE-13018-02 and GE13018-04 as defined by the plane of the plastic bottom of the PYRAMID GOAL pieces GE-13042 and GE-13084.


In either of these cases, a portion Section 2.26 (http://frc-manual.usfirst.org/viewItem/179#2.2) is being violated.

However, in all three (flawed) interpretations, the height of the PYRAMID is higher than 90".

Perhaps a better way to phrase the question is "At what height is the top RUNG found?"

[engunneer]

I intended that answer to be 120". I will double check. ( I thought I fixed that one already)

[Tetraman]

I got a 90%. Missed BUMPER ZONE, and starting height. Pretty good.

Same score, same wrong for me.

I really don't think I'd want to build a robot with such a starting height though...

[ferrari77]

I got 95% :D
But the question I missed was

At the start of a match, a robot's maximum height is:
3 feet
84 inches
54 inches
5 feet
6 feet

I picked 5 feet but the quiz says its 84 inches, is that right?

[chmorroni]

At the start of the match you are in your Auto Zone, so you can be up to 84" tall.

[EricLeifermann]

There are 6 goals not 5, ONE 3 point, TWO 2 point, TWO 1 point, ONE 5 point.

1+2+2+1=6

[engunneer]

There are 6 goals not 5, ONE 3 point, TWO 2 point, TWO 1 point, ONE 5 point.

1+2+2+1=6
Where is the second 1 point goal?

[Radical Pi]

At the start of the match you are in your Auto Zone, so you can be up to 84" tall.

Or more precisely you're touching the Pyramid, which also grants the 84" height to those that opt to start out of the Auto Zone for the extra disc

[Taylor]

Excellent work. Thanks for sharing this. With your permission, we will certainly use this before tomorrow's discussions.
95% (missed the one about when students may remove robot)

[Gregor]

90%, I still have some work to do. It turns out that email blasts aren't official interpretations of rules, and that I can't add to 130.

[TVwazhere]

Total Correct: 10
Total Possible: 20
Score: 50%

You have failed this test.

:'( I forgot about the colored discs!

It's a good test though

[EricLeifermann]

Where is the second 1 point goal?

Your right there is only 1, my symmetric mind kicked in and I put one on each side when doing the quiz....

[iPenguin]

I got 90% so not bad for me. Missed the ones about starting height and surprisingly rule clarifications. My interpretation of that question was that the "manual" was the first printing and of course not very clear, so I only put Q&A.

[GaryVoshol]

I wish the ref test was this easy ...

I question this question:
Students may remove the robot from the Pyramid immediately after the match if:
Removal must be done with the permission of field personnel (FTA, FTAA, ref, Field Supervisor). So none of the answers are correct.

[nikeairmancurry]

Total Correct: 17
Total Possible: 20
Score: 85%

You have passed this test.

Close enough

[engunneer]

Gary,

Thanks! I will alter the question.

[engunneer]

Statistics:
In the first 20-ish hours this has been posted, the test has been completed 418 times.

The fastest passing grade so far is M. Farr from FRC 1425 at 1m43s (95%)
The fastest perfect score so far is A. Childers from FRC 3079 at 1m54s
The best-quizzed team is FRC 4063 with 17 people completing the quiz (it appears they did it all at the same time too)

Some of the fake names are amusing, but please still put a real team number if you are using a fake name.

[Dinoyan]

i got 80% YEAH :)

[Christopher149]

90%

Missed the exact number of discs in a game and that the manual contains rule clarifications (isn't the manual the source of confusion, not clarification?).

[Siri]

I wish the ref test was this easy ...

I question this question:

Removal must be done with the permission of field personnel (FTA, FTAA, ref, Field Supervisor). So none of the answers are correct.I agree, this question should be rephrased. Wouldn't want drivers doing anything unsupervised (unsafe) based on their interpretation of the word "immediately".

Or more precisely you're touching the Pyramid, which also grants the 84" height to those that opt to start out of the Auto Zone for the extra discJust to clarify, you actually don't need to start outside your Auto Zone for the extra disc; you just need to be in contact with carpet other than your Auto Zone's.

<G06>
TEAMS may preload White DISCS in or on the ROBOT before the MATCH.
A. If the ROBOT is in contact with any carpet outside its AUTO ZONE, the ROBOT may preload up to three (3) DISCS.

This means that if you are straddling the Auto Line, in contact with both Auto Zone and center zone carpet, you still get the 3rd disc.

[engunneer]

I agree, this question should be rephrased. Wouldn't want drivers doing anything unsupervised (unsafe) based on their interpretation of the word "immediately".

I changed it to include "(After the "All Clear" signal is given)"

[engunneer]

at the 48-ish hour mark, we have 964 results - I'm having to actually do some number crunching to get nice data now.

Best Quizzed teams:
team unique names
1983 48 (Go Skunkworks!)
3324 38
2506 36
334 26
4063 17
3824 16
399 14
3319 13
4475 13
1529 11

158 of the results had no or nonsensical team numbers.
62.6% of all attempts had a score >70%

I'm looking for more quiz question ideas. I've gotten a number of nice corrections here and by email. I'd like to expand, though.

Thanks for all the great feedback!

Edit: another skunk finished while I was writing this post

[jsasaki]

95% Missed the one about rule clarifications

[JosephC]

Retook the test, got 100% this time. One of my team members is impersonating me on the test so It may look like I took it a ton of times(he doesn't know my real email though ;) )

[bardd]

95% on first time. got the number of feeder slots wrong TT

[engunneer]

I'm really curious how many of the 1111 and 1234s are from the real team vs somebody just hitting a random number.

Is there interest in a continued ranking of best-quizzed teams?

[dellagd]

95% I guess that's acceptable.

It was done at 6:40 am on a school bus, so Im down with it.

[sarah_storer]

Got an 85%

...missed starting height, num of disks in an alliance station, and when students could remove the bot from the Pyramid....

Not bad:)
