pnuematic wheels

[gorrilla]

do we get pnuematic wheels in the kit i dont remember but i saw other teams that had them, or are they cots. or am i going to have to take them off the 2004 robot?

Answer #1: Nobody knows. Wait until January. They have not been included since 2004.

Answer #2: Many teams do use COTS pneumatic wheels. Find the usual suppliers (McMaster, MSC, etc.). Note: if the size is less than 6", you'll have better luck finding pneumatic casters.

Answer #3: 2004's wheels were/are COTS 12" wheels from Skyway. I'm not sure if they're still COTS, but it doesn't hurt to investigate.

If you are developing something for next year, use caution--we don't know yet what will be allowed.

Although next years kit may be different, for the last two years, we have been getting 6 inch andymark wheels, with no Pneumatics. Our team was not around in 2004, and does not have any pneumatic wheels, so therefore I have no idea what model, etc they are. However, since teams still use them, they, or a similar wheel, are almost certainly available somewhere.

Perhaps someone who participated during 2004 could enlighten us on where one could get more.

EDIT: Eric beat me

Looking into 330's favorite center wheel type, eh? Pneumatic casters, McMaster-Carr, 6". Modify the hubs, though. And 2004's KOP wheels are 12".

Stock hubs on those pneumatic casters can't take a key/bolts. You need a custom hub to allow for either a key/broach or a sprocket interface.

The Skyway 6" pneumatic wheels will accept a sprocket off the shelf.

I think Cory means 8" diameter wheels.

They can be found here at the bottom of the page.

To be honest, I hate these wheels. The inflatability makes for all kinds of weird driving and bouncing. I much prefer the stability of hard wheels.

But if you use only two of them (like 330) it'll probably work fine.

Nothing said about Skyway 6" wheels, Cory. The wheels referred to (330's) aren't Skyway. (Though they could take a sprocket, if you had standoffs and 4 extra-long bolts.)

Are the ones we used to use 8"? I thought they were some funky diameter like 5.75" or 6.75" or something.

At any rate, that line of Skyway wheels was the one I was referring to.

Yeah, I guess they were 8". Those will accept a sprocket. The 6" solid and 8" solid have also been in KOPs in the past.

One thing about those big, bouncy Skyway 8" pneumatics, they GRIP!

Well... you can make them any conceivable size you want within the limits of the hubs

Ohhhhh yes they do. Test out anything you want to prepare for the upcoming season, but if you're going to use these guys pay careful attention to your turning ability, the amount of scrub you create while turning, and how many amps it's going to take to make your turn.
