12" Omniwheel

[Gabriel]

Does anyone know where we can get a 12" omniwheel with a 5/8 keyed shaft on very short notice? I couldn't find any on the web.

Is there any team that has made their own that would be willing to trade or donate them to a rookie team with very limited resources?

Thanks,

we bought some 3.5 inch omin wheels this year and ran about $90 for 3 (we are using 4 on our robot) we got ours from omniwheels.com i am not sure about 12 inch ones but you might want to contact them and see if they have them

Omniwheels.com isn't a website, did you mean omniwheel.com?
Those wheels look great but they don't look like they come bigger than 5" diameter which is way too small for us.

If you are not driving the omniwheels and want some cheap alternatives here they are:

You could always order some Delrin or Teflon and make skis to support the robot

If you just need a low friction wheel take a sheet of plywood or normal wood and cut a twelve inch circle with a jigsaw. Then take some slick material (thin teflon works nice) and then use wood screws and sink the heads below the surface (no metal cleats) This gives you a nice big wheel with very little weight and friction.
