SO MANY G02 VIOLATIONS! :ahh:

What's she weigh in at?

You guys own a cnc plasma cutter? lucky. How does my team get one? Very nice pyramid

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

that looks way better than U-bolts and plywood

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

Hahaha:p
Sweet pyramid guys!

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

Haha, yea. It's incredibly useful. I managed to pump out the full set of gussets in less than 15 minutes.
We have the 4'x4' table made by these guys: http://www.plasmacam.com/indexfla.php

I'm not quite sure of the overall weight. It's really not that easy to weight this thing.

Thanks for the compliments guys. We just want to give some inspiration to teams out there. CONDUIT WORKS GREAT! =)
Albeit, we had to use extra ventilation and masks to weld this thing. It was well worth it.
The hardest part was probably assembling, we needed about ten people and a dozen 2x4's cut to length to get this thing in position.

And I'm sure that the judges would overlook the G02 violations in this case. ;)

Did you use thick walled conduit.

Is the OD spec of this material not ~1/8" larger than the 1.5" of the game pyramid tube spec?

We were also thinking to use the conduit and ignore the size difference.

Which set of specs did you use? Noting the differences between the different drawings we are a little concerned about building ours until the GDC clarifies which one is correct...::rtm::

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

I've learned the hard way that all FIRST specs are nominal. Failure to plan around that fact has bit us on more than one occasion!

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

Not really the answer I wanted but at least it's honest :D guess we'll just pick the one closest to the dimensions given by the game manual...

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

Well, let's be honest... Did they give us a spec on how thick the powder coat is? (I do not believe they did!)

Building for less-than-perfect fields is essential for success!

Kudos to you and thanks for posting this variant.

Can you confirm my back of the envelope calculations that the distance from center to center of the horizontal members in the plane parallel to the floor is approximately 22 inches?
:D

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

Good job, I was wondering if this might work. The competition pyramid has to be built to a pretty high standard, given that it has to stand up to up to three robots for many matches, but something lighter should certainly be fine for testing.

Echo that, inquiring minds really want to know - the $$ difference is about 3x.

Re: pic: Just finished our pyramid. Conduit seems to work fine.
 

Andrew,

I am pretty sure that the 30 inch measurements are in the plane parallel to the floor (the length of the diagonal members are 104 inches).

It never occurred to me that the actual distance (in the sloped plane) was greater than 30 inches. My (probably wildly innaccurate) visio model shows it to be about to 32.4").
