Why are we bashing students for being so proud and inspired by a part design that they make a beautiful presentation of it? Yes, the render isn't as important as the CAD file, but no one was saying it was.

Oh no no no, sorry you misunderstood, I wasn't commenting about this particular render. I was directing that at Matt from 1515 because I have talked him a lot and he mentions learning how to render better quite often. The comment wasn't directed at the OP. I wasn't bashing anything.

Is the purpose of the dual rollers to increase load-handling capability?

Did you consider instead using a single row with larger rollers, to reduce gaps and overlap ?

Lots of cores threaded together, I would have to ask the owner of the computer exactly what specs of it but I know its a Dual-Hex core 2.66 Ghz Or something like that. While I only have a dual core.

The dual roller we find more efficient from experience in the past with mecanums however the challenge of the design with a dual roller is much harder than a single roller. I can assure you in the second wheel (also posted) the wheel has a perfectly round projection.

Not to take away the work you did rendering these (they are incredible; having done renders way back when in AutoCAD on a 386 computer I know there is a ton of work involved), but the thumbnail photo of the other photo has the strange effect of two little fuzzy animals with big bulgy eyes. It doesn't show in the larger photo, but now I can't look at the Image Gallery and not see them lking back at me.

That might be the work of the image converter... CD wouldn't take the original photo because it is a 40 MB file. And CD also wouldn't handle the smaller PNG file. SO I had to find a converter online since I don't have photoshop or anything on my computer to convert to a JPG file. I just looked at it and saw what you were saying.

If you are interested in the FULL quality image send me a PM because I have to track down the file and I can attempt to email it to you.

Then you should understand how difficult other arts, such as writing and drawing, really are.

I'm glad you see it too. The illusion is only in the thumbnail; the full photo it takes some effort to see the fuzzy animals. I don't think it's the conversion that does it, just being a tiny picture, and the natural loss of detail. I copy/pasted the thumbnail into Paint Shop Pro and at triple size the left fuzzy could go either way (animal or wheel), but at 4x there was enough detail to make it a wheel first.

Thanks for the offer of the full photo, but I must decline. If I save everything I liked, even electronically, I'd fill up my hard drive pretty quickly. As it is (before computers became my storage closet) I have a basement full of stuff. I'll just keep the memory of fuzzy mecanum wheels staring back at me and this (amusing?) picture...
