New AndyMark Wheels
 

Has anyone seen these wheels before

I think they might be geared toward FTC but maybe they could also be used for FRC.

Any thoughts?

Re: New AndyMark Wheels
 

Haven't seen or heard of them--but I do know that a number of FRC teams use 4" wheels as their go-to size. Most folks go with 6" wheels, or 8" wheels, but there are a few that go 4". I want to say most of the ones that do are using a modified WCD.

Re: New AndyMark Wheels
 

They come in 1/2" hex, and 8mm key bore, so my hunch is they're intended for FRC.

They look like they could be used as a drive wheel, with a respectable amount of grip if their number is correct. Colson(ish) looks.

I ordered two to try out, you'll never convince me to not run nitrile roughtop for high traction setups.

They are VERY light for their size for such a durable looking wheel, so I'm interested in them for rollers, etc...

I'll post when we get ours.

4 inch wheels like this would be a little large for FTC if you ask me (though no doubt someone has/will try).

I could see the benefit for robots that use more than 6 wheels in a drive system (or just like them small) or perhaps for different grabber or shooter mechanisms. For the price I've considered getting our team some just to play around with and compare them to other wheels.

Re: New AndyMark Wheels
 

We've been looking into using 4" wheels so we can get our CoG lower. Not sure about using WCD though. I'm not sure if these are the 4" hi-grips

Re: New AndyMark Wheels
 

if these were 3" wheels, we'd try them on our Octocanum. 1/2" hex with no need for a special hub? Yeah, I'd look at them over Colsons any day.

Re: New AndyMark Wheels
 

Well, 4" wheels are the limit for COTS wheels in FTC, so they may very well be aimed towards that market. Plus it gives a CoF for FTC foam tiles.

Re: New AndyMark Wheels
 

Does it seem as though they could be used in a drivetrain?

Re: New AndyMark Wheels
 

Are the tread on these wheels similar to bane bot wheels or that of Colsons? In other words do these look usable for a drivebase, before I buy a pair to test them?

Re: New AndyMark Wheels
 

The tread is the same as the hi-grip Tread material.

Re: New AndyMark Wheels
 

It says it is TPU, but it doesn't give a durometer rating.

Re: New AndyMark Wheels
 

Durometer is 77A on both. http://www.andymark.com/Rubber-Treaded-Wheels-s/220.htm

Re: New AndyMark Wheels
 

3'' or 2'' versions of these would be greatly appreciated, yeah. Price-wise, these look like they'd blow Colsons out of the water.

*face palm*

Didn't even notice that

Re: New AndyMark Wheels
 

They do have the coefficient of friction listed for carpet as well as the FTC soft tiles so I assume they were marketing this to both FRC and FTC.
