What do you do when you have a bunch of Vex kits, a lot of students with ideas, and Shrink ray developed during the off-season? Well zap your full size rack down into miniature! 
More seriously, here is an exact 1/3 scale version of the rack from this year's game as it appeared right before it was completed. The entire structure was made out of misc. parts available from Home Depot that cost about $55.
The best part of it is that all the spider legs behave almost exactly as they did on the full size FRC version at the Manchester, NH kickoff event. Currently we have two groups of students building several Vex robots with various arm, elevator, and manipulator designs that they came up with.
Although we plan to eventually build half of the full-scale rack as soon as we start getting parts back from the CNC shop, this is a great way to prototype ideas and strategy early on in the build season!
(For more information on this, see my white paper Using Vex in your FRC Team! or Team 40's Mini FRC competition.)

That is awesome. If my life depended on it, I could not make a perfect octagon. Kudos for everybody who can, hehe. Good job on that mini-Rack, and have fun with your VEX robots. Sounds like fun. I should have bought a VEX kit when they were like 100$ when my local radioshack went out of business.

Sweet can I come and play?! 
Looks very much like the real thing. One question, what are you using as the game piece? Kudos on the great work!!

The funny thing is that I still have all those mini tetras, goals, and most of that robot still intact at my house, as they are great PR tools for our team. They are transported easily, easy to set up and explain, and the best thing is letting complete strangers drive the robot and score tetras, as they always love it!

Question- How have other teams gone about building the acual size rack?
It's huge and takes a lot of materials. Any suggestions on how to make a cheap and easy rack?

Awwww. And I thought our 1/3rd scale rack was sweet. Thats awesome! You guys order 4" Cathode Tubes for it? Very nice Art! Very Nice!
Can we borrow that Saturday?

Very nice Art! I would expect no less than an awesome start to the season from you and the rest of GUS by making this.
Now all we need is some detailed pics and some CAD drawings to recreate this beauty.
Or at least some video of the rack in motion to see how it compares to the real thing. 
Kudos to 228 for the mini-rack!

) Maybe it'll be wise to make one like you did so everyone understands the true nature of the rack before our first competition.Or maybe after I CAD the whole rack up, I'll just pop the parts in the rapid prototype machine at school. Who knows.

Nice! I wish we had enough people (and money) to do that
