Thanks for the details. But there's a new probelm. How do i join the PVC to the flanges? They're 2 different sizes. Is there an adapter or something?
Any information would help a great deal.
Thanks again in advance

What was done on the game piece was a wood dowel plug was installed inside the plastic and the set screws ( set screws suck ) used to hold in place.

In high stress areas there will be a thru bolt for safety.

[Gadget470]

is the dowel plug the official answer or has it been deemed official that set screws suck?

Has any team built the goal structure yet? If so, how many balls can it hold?

Fox, simple math, if the goal is 6 feet tall, that's 72 inches. Each playground ball is 10 inches. 72 / 10 = roughly 7 balls in the tall portion.

[Mike Martus]

That's now official.

The plug is just for support and will not affect the game piece.

[Mr. Mac]

How authentic do you want to be? We used Kee-Klamp floor flanges (a catalog order item), but the Hazel Park team is using the 1.25" Home Depot floor flanges and screwing a threaded PVC fitting into it, then inserting the PVC columns into them. A quick, low-tech solution would be to take some 2" by 4" boards, form them into a square, drill a 1.25" hole half way through them and stick the PVC into the holes. Whatever's right.

[Mr. Mac]

The field border is made from two 2" x 4" boards fastened at right angles to each other; a flat 3.5" side is vertical and faces the playing field. The other 3.5" side lies flat on the carpet and has holes drilled in it every 8' where a 16" piece of 1.25" PVC is inserted vertically; each piece of the PVC pipe has holes drilled into it where ropes pass through; there are two ropes that go through each upright PVC pole and encircle the field. This barrier is not meant to be interacted with by the robots; it has been designed to contain rolling balls and to keep robots from accidently leaving the carpeting. In front of each player station will be a 3' tall, 4' wide barrier made from pipe and Lexan; balls will be able to roll under the barrier as there is a 12" high slot at the bottom where there is no Lexan.

Can someone please measure the following on the ACTUAL competition tower:

1. The distance from the floor to the top of the plywood (the surface where the PVC poles are mounted)

2. The distance from the outer edge of the plywood to the PVC (not the flanges) ie. the inset distance, both on the encased PVC and the unencased PVC

Thanks.

[Justin Howard]

The distance from the floor to the top of the plywood is 4 5/8"

The distance from the outer edge of the plywood to the pvc is 2 1/8"

What is the greatest possible diameter of the flanges on the cart? ( The part where the pvc is insearted, not the bottem of the flange.)

Thanks

From DanLevin53:
Fox, simple math, if the goal is 6 feet tall, that's 72 inches. Each playground ball is 10 inches. 72 / 10 = roughly 7 balls in the tall portion.

Consider also the other 5 inches from floor to flanges, 6, MAYBE 7 balls will fit. + 2 in the mini tower

[Mr. Mac]

I can't say the exact outer diameter at the top of the cart flange: they are at school and I'm at home now. I'd guess about 1 3/4" but here's a picture: you can guess for yourself...

[Mr. Mac]

Something went wrong: I'll try attaching the picture file one more time.
