I noticed that, and when I tried opening the attached .step file, Soludworks stopped responding before it even started parsing the file.

Just try opening the regular .step file.

Got it working thanks to Brandon Liatys. Thanks for the help, though.

What pressure is it designed to have if used with the 3/4" bore pancake pneumatic pistons?

Still wondering on how the Roughtop/Wedgetops will attach to these wheels..? I suppose it's a drill and rivet thing for now. :(

Thats awesome Paul. Thanks for the info.

While the traction wheels are designed to use their own tires (which, I think lots of people will be VERY happy with once they have the opportunity to play with them) you can easily attach traditional roughtop or wedgetop treads.

The method I used:
1. Assemble the wheel.
2. Cut the tread to length.
3. Hold the tread in place with a few zip ties or a belt.
4. Drill holes through the ends of the tread through the wheel rim using a small pilot bit.
5. Fasten the tread to the wheel using rivets, or self-tapping plastic screws.
6. Remove the zip-ties.

I am experimenting with some self-tapping screws that work REALLY well. While I would personally use the VEXpro traction tires, we will make sure there will be good options available for those who want to use their own tread.

The tires are very exciting to me, I can't wait for the results of your traction tests!

Just want to add in my excitement for this! Being from an electrical background I'm obviously more excited about the Jag's and Victor 888's, but still very awesome!

Thanks Vex and IFI!!!

I am really excited to see the supply of gears available. There isn't anyone that I know of with such a large range of gears for the prices they have.

Wow, this is mind blowing.

Huge thanks to IFI & Vex.

On another note, what say you all about the Mecanum wheels on VexPro? Significantly cheaper, so I'm wondering there's any tradeoff or if this is just a godsend.

It's funny... we actually had this discussion during the pricing meeting.
"If we go with that price, will people think they're crappy? Should we just price them higher and make sure that people understand the quality level we're going for?"

We decided to go with the low price and hope that the community will understand that just because they're inexpensive, doesn't mean they're cheap.

Haha, interesting coincidence :)

Well, that's just phenomenal! We're a second year team with a tight budget but were giving a strong look at using mecanums this season (barring any circumstances that would make it a bad choice in the game this year) but the pricetag of over $400 was hefty one.

Glad to see some great quality wheels at an even greater quality price - can't wait to get our hands on some!

Great to hear! We're now re-designing our already re-designed octocanum drive to incorporate the IFI mecanum wheels. Expect an order next week! :)

It is tough to provide a load capacity on something like a wheel. I can tell you that these were designed with FRC applications in mind. They're built to be tough, and survive even the worst of what FRC teams will throw at them.

They're not built to be used as an all-terrain wheel-chair or something... they might work for that, but that isn't their designed usage.

Does that kind of answer your question? Is there a specific value you're interested in?

-John
Hi John,

I think others and you have fleshed out most of the ideas behind this, but I do still have a few questions about longevity of the mecanum wheels. Are the rollers molded directly to the axle? What material is that axle? I expect it will be able to handle normal driving conditions just fine but what about after 3 or 4 competitions...can rollers be replaced? More importantly, can an axle be replaced if it is bent? The body and spokes of the wheel does not concern me at all. We've had bent and bound rollers before but they were easily replaced.

Thanks for all the information you and the rest of the VexPro team are providing on these products!!

Kev
