What material is the Sally Door made of. I see the Drawbridge is made of Polycarbonate but I don’t see the material for the Sally Door.
I believe the sally door is made of the same material.
Hope this helps
Material: clear polycarbonate, .125"Thick
Print to look like wood
Per dwg GE-16044 pg 90/290 of 2016 Field Component. Wow those drawings are a pain to read!
That seems really thin.
Yes, Sally Door.
Your response got me to dig a bit deeper. From page 82.
NOTE: Place two GE-16044 parts front
to back, so that the printing is
sandwiched between the clear portions
of the polycarbonate, also making
sure that the holes line up properly.
Secure those parts to the Door Frame
with 1/4"-20 hardware called out in
Have I said that I have never been a fan of the field drawings?
While we’re on the question of the sally door (and by extension the drawbridge) . Since they both extend out into the neutral zone when opened all the way, does anyone know if it is a viable strategy (counting as crossing a defense) to -
- open them from the courtyard (easy) side
- get the robot and bumpers completely in the neutral zone while still holding them open
- bounce the door so you’re not touching it for a moment (so you are for that moment completely in the neutral zone and not touching a defense)
- still propping the door open after the bounce then
- proceed through the defense completely into the opponent’s courtyard
I thought it would be but might be tricky to get the ref to see it that way.
If the ref (or scorekeeper) doesn’t see it, it didn’t happen. And trust me, they’re going to be busy looking all over the place.
Is it a valid crossing? Yep. Will it get scored as one? I’d go 50-50 on that, or worse.
yes, Sally Door.
Yes. The doors are extremely thin. I was at the full field in Manchester, and yes, they are incredibly thin and incredibly bendy. The sally door is a little bit less flexible because it has a triangle brace thing so it is only floppy like polycarb the upper half of it.
The draw bridge on the other hand is ridiculously floppy. Not only will it be hard to just get to the ground, but when its on the ground if you hold it there from the edge of the door, the polycarb bows up quite a bit from the springs that pull it back up when you let go*. It will be extremely difficult for any team to open it without just going through the courtyard and holding the door open for your partners.
As far as the punching idea goes, that ones a toss up as to whether or not its legal. I think it most likely will be illegal because its too much work to ask the refs to keep track of that and I believe that they said somewhere the robot has to be free and clear of the defense in the neutral zone for it to count as a breach(I forget the exact wording), and even though you may not be touching the defense, I personally would not call you free and clear of it. But that is just my 2 cents.
- As a sidenote… The plywood door Ri3D 1.0 used is not at all acurate and there is no way that robot will be able to lower the door on its own. Make sure you plan on this when you design your mechanisms. I know soooooooo many teams will think that their robot will be able to do the door and show up at the event only to find that the door is not even close to the door they had at home.
Yes - I also noticed how flexible the Drawbridge was in Manchester. Plan on it curving forward about 30 degrees if you’re pulling it down from the top.
I assume the wooden Drawbridges we build will be stiffer. Keep that in mind when you’re designing your solution.
