I like them they look cool. Did you bend each tab one at a time or did you have something that bent them all at once. by the way i like table the mecanums are sitting ;)

Those look really similar to Andymark's mecanums, why didn't you just buy those?

Pretty nice job though :)

One at a time, ten pieces, twenty-four bends per sheet. Hold the piece in a vise, bend, check angle, adjust. Mildly time consuming, to say the least. Still gotta make a spare for the right side... :D

Well, we're from Brazil, so shipping five or six of those from Indiana would be outrageous. Anyway, we're on a really tight budget this year and those wheels were practically free:

Aluminum sheet and laser cutting - free
Rollers - $ 0.80/pc
PVC bushings - free
Aluminum axle for the rollers - $ 5.34, enough for about twenty wheels
Bolts and nuts - $ 0.34/pair
Machining time - free; lots of students and mentors put lots of hours making the rollers, cutting and bending everything.

So, those four wheels in the pictures cost us around $60 dollars, less than one mecanum from AndyMark (and don't take me wrong, they're great).

This wheels are very nice.

You guys did a great job on those specially considering the bends were made individually. They look very rigid too.

Amazing what you can still get done when you go three weeks without a KoP. Excellent work!

MikeM.

The rollers are made of really hard rubber that, once sanded down, softens a bit. Weird, I tell you. Those rollers are part of a car suspension system, I'm missing the English term here... :confused:

They're not perfect, but the best we could find in the local commerce. Maybe next year we'll go Jester (http://www.chiefdelphi.com/forums/showthread.php?t=54752)! :yikes:

None. Jester drive is a mecanum drivetrain. It's just one specialized edition.
