Nice mecanums. a Hexagonal bloomer design.

my favorite.

Won't those not work as mecanum wheels since the rollers point in opposite directions on the same wheel?

Or are you just using them as omniwheels for a killigough platform?

On the "runs circles around West Coast Drive", you got any video? If you don't, I'm rather skeptical.

Oh WOW! Interesting idea.....still I must echo the concern or others... are these four different wheels or single wheels with dual sets of rollers.... not sure the latter could work.

Steve

<afterthought> OMG!!!! These wheels MOONWALK!!!!!

[MarkoRamius1086]

Oh! I think those are a full set of four... correct me if I am wrong.

:yikes: Those look like really high quality rollers! Were those purchased from some obscure secret warehouse or do you have a sponsor capable of advanced machining? (Presumably CNC mill, CNC lathe, and some custom hardware...)

Good luck this year!

OK... there's the West Coast Drive so ... You'll have to name this the Michael Jackson Drive!!!!

What's the coolness factor for those wheels? OVER 9000!!

Assuming these are only 2 wheels... if you could tilt the wheels on one set of rollers or the other it would make an interesting drive.

Our programer suggested that. Although a pneumatic system would be much quicker at changing directions, you still just have a omni directional drive. Now if you replaced on of the wheels with a plaction or other wheel, and actuated that up and down. Essentially it would be a different way of doing a Octocanum drive.

Yep, between our two gracious sponsors HK Plastics and Aztec Tooling, we have 7 CNC mills, 1 CNC Lathe, 5 Manual Lathes, and 3 Drill Presses. :D we are spoiled. The Hub of the rollers used some fancy set ups on the Drill press/ Mill (didnt use a single CNC on them, and the students produced them). The Rollers were made on the CNC lathe.

The circles part was a joke. We don't see how these wheels would work as shown in the picture, so were guessing that it will just go around in circles. Hopefully we'll have some footage up tonight.

Im glad someone got that :]

whats the outside diameter on this set of wheels... looks less than 6"?

4 inches. Good thing we have a flat field this year! We'd never get over any bumps otherwise! I think we've epitomized "low-rider": our gearboxes nearly touch the carpet.

Don't forget that the field isn't perfectly "Flat".

There are bumps by the tower from where they are mounted under neath the carpet. If you've got about .5"-.75" of Clearance you should be alright.

that bump is nothing compaired to last year lol go fast enough and your robot doesnt even feel it

we have 3/8 inch clearance.

Words fail me. :) Those are some pretty sweet rollers. I hope, at some point, I get to see these in action in person. Maybe even up close in your pit somewhere.

[Bjenks548]

Just wanna confirm are those 2 wheels or 4?

[Brandon Kirklen]

They are stacks of 2 wheels on their axles. You're seeing the left and right wheels on the same axles thus the opposite facing rollers. Total of 4 wheels with two on each stack.
