Scoring Pegs

Hey guys I have a minor question for yall. Either I didn’t see it in the manual or it just isn’t there, does anyone know the height of the scoring pegs from the floor. We are designing our robot and we just want to be able to drive up to the peg of our choice and slip the tube on, no lifts to make it easy. But we need to know the height.
Thanks
Daniel

Chief Delphi has a great search function for previously posted threads. This specific question comes up several times a day!

Here is a link to one such post.

Hope this helps!

Thank you so much, to be honest I totally forgot about even searching it. Thank you

Ranging from 2.5ft to 9-1/3ft, That’s going to be a fun challenge!

To determine once and for all what the peg heights are, go to this link:

Download the Game Specific drawings for all the playing elements on this year’s field. Specifically, look at drawings GE-11000 through GE-11005. From these you can determine measurements from the 11 gauge steel base plate that sits on the floor up to the bottom of the pegs, or to the center of the end disks which are welded tangent to the bottom of each peg’s pipe, or to the top of this disc. Since I don’t know how you will plan on aiming at the pegs, I won’t publish actual dimensions here, but you can easily calculate them.

Plans are also on this site for team-built pipes made from PVC plastic pipe. Be careful when you make the pipes out of plastic. Not all tee-fittings are the same size, and pipe doesn’t always bottom out when glued into the tee-fittings, so be sure to measure the finished products when you make them.

You should assemble, then measure your rack pipes before taking them apart for application of glue and reassembly into their final configuration. Also be sure to have a plan for keeping the pegs all going in the same plane. Marks on the fitting Tees and pvc tubes will help with alignment. Keep a sharpie marker handy.

Hey - Retired Starman - I am not afraid of mechanical drawings; but figuring out the peg heights from the drawing FIRST supplied is a giant pain the anatomy; and among all the things I might encourage students or myself to practice, that sort of tedium isn’t high on the list. Instead I would urge folks who create drawings to practice making their products as useful as possible.

With that in mind, if you have gone through the detective work / chore of doing the arithmetic, and of factoring in all of the additions created by the baseplates and boxes the poles rest in, how about sharing the result with us?

Listing a summary of the various parts’ contributions would set a useful answer apart from the ones that simply list 6 numbers.

PS: I’m not above suggesting that lazy folks should read the rules and other docs instead of asking the rest of the world to do their homework for them; but I think this falls into a different category.
