-7.5" pneumatic rim (squishes down to 6")
-Gold plated...
-Spinners...
-Embossed with our logo...
-If only we had the $$$

Very cool

Animation???

Here's an animation i made for Hachiban VIII's wheel.
Here's the GIF


and here's the video but photobucket makes it look horrid.

OK, so maybe it's not Inventor or a robot wheel...I used CATIA to do this about a month ago.

[Dan Zollman]

Random design for fun. 3 inches; the iProperties box says it's .189 lbs...





The tread should have more raised lines on it between the FIRST logo imitations, but the emboss was taking forever to calculate the way it is now, so I left that out for now.

[sanddrag]

Wow, that's hot. You've got to tell me how you did the FIRST logo on the curved surface like that.

[Dan Zollman]

After revolving the inside part of the tire, I created a sketch normal to the tire's surface. Then I drew up the FIRST logo. (It's just an imitation of the logo; I guess you could trace a sketch on top of the real logo image to make it exact. All those dimensions are there just because I wanted it to be fully constrained.)



Then I made a rectangular pattern of the logo, inside the same sketch, making sure that the width of the pattern did not extend past pi * diameter of tire surface.



Then I embossed the sketch, choosing a raised emboss and "Wrap to Face" with the tire surface.



You could also emboss one instance of the logo and circular pattern the Emboss as a feature.

Gah. Catia looks more bizarre even than Pro/E.

[[527]phil]

I gave up learning Catia once i got my hands on Inventor, lol.

This isn't really a wheel, it's a Cog, and it's not done yet but I figured what the heck.

[SamC]

This is my first real object made in CAD... So if you actually know CAD, please PM me and give me some tips on making "real-life" objects, (ie. wheels, robotics parts, etc...) So here it is.




-3" Chrome Wheel
-0.5" Wide
-(Supposedly...) 1.5lb
-3/4" Hex Drive

So it's more of a work of art, so I guess you could call it a "Couch Signature" it's one of a kind, never to be reproduced again... LOL

[sanddrag]

How does the inside of the wheel attach to the outside? Am I missing something? Also, 1.5lbs is quite heavy for a wheel that size. (in FRC anyhow) What is the material? Also, you may not want to put a zillion holes in it. That will take a while to drill. And how do you plan to make the cutouts? Laser? Waterjet? You can't mill that. The milling cutter has some radius to it. The machinists I know like to use a 3/8" diameter tool at the smallest. Makes life easier.

[SamC]

Yeah I know, I am just learning how to use CAD, so this wheel design is definitely not realistic to use. Didn't really think about how this would be machined or anything. But if you have any CAD tips, please do PM me.

Thanks for the "constructive" criticism.

One of the best things you can do to improve your CAD is to learn to machine. Once you know the constraints of your machines, you know how crazy you can get with your designs. Plus, it makes it easier on your machinists if you design something that can be machined easily.

[Dan Zollman]

Yeah, my wheel is definitely NOT something to consider for production...

[Greg Needel]

not really anything that special but I like it.... .67lbs for the 6 inch
