Whoa, nice work.

Are y'all planning on using a belt drive for the wheels, or is that just a placeholder?

It just means that I'm too lazy to model roller chain.

I guessed so (the would-be pulleys didn't look like pulleys).

Can you post a close-up of the transmission? Unless I'm a victim of forced perspective, it looks like a right compact number.

What is the purpose of that third sprocket? Sensor perhaps?


Why exactly are you using an AM mecanum anyways? Didn't you make some really neat mecanums earlier this year?

[SamC]

What program is that modeled in?

Yes, as soon as I finish modeling the rest of their parts. They're missing a bearing, a bushing and encoders. There's not much to look at, really. It's a two-stage reduction based on some of the parts provided in the kit transmissions.

The idler will drive encoders for position sensing. They also increase chain wrap.

I'm using AM's wheels because the wheels I developed do not belong to me. They were also far more expensive to manufacture.

Solidworks 2005

what motors are you going to use?

[Bill_Hancoc]

Wow that is some amazing modeling...what was that done with....looks very cool and promising

[Joe_Widen]

Almost looks real. Great CAD. Good luck with your mecanums.

wow ... thats really good!!

Are they the AndyMark Mecanum wheels?

From picture description: "This is a look at what FRC488 is planning to prototype this Fall thanks to AndyMark's new mecanum wheels."

What's the purpose of the large plates on either side of the wheel? Why not a much smaller system to mount the wheels and/or bearings?

[Crazy Ivan]

Wow, great work. Thats an impressive model. I have one question though, do you plan on putting a suspension on you chassis? I can tell you from our experience with mecanum that constant contact is important. Our team, 40, used rubber bumpers on our wheel pods to keep contact. Also at nationals we saw another team (I'm terrible at remembering team numbers) who used small pnumatic pistons for a suspension.

Looks wicked cool though, Good luck!

i am guessing protection to the wheels and stability?
