Ok, so before you hear stories left and right and before anything else goes on with assumptions, I'm going to tell the whole truth.

This is my first year being part of FIRST robotics since we didn't have it as part of my HS. I heard about it from my roommate last year and joined up on it b/c it fit nicely with a course we take here.

As part of team 1493, part of my job was to work on the omniwheels in question. I worked with another teammate (known here as gofortyeight). We decided that we'd want omniwheels on our robot and so after that it became our job to make sure those got done right. So i stumbled upon the omniwheels and later saw the post that Andy said "Teams can then choose to purchase our assemblies or make (and/or alter) these designs themselves." I saw the wheels and they looked perfect for the job we wanted to do with them. With the permission on that thread that anyone was allowed to use them to make their own with their own fixes on it, I saw no problem in getting the files from the site. At first the step files wouldn't work for me so i had started using the pdf engineering drawings to make them in SolidWorks, but then Garret got it to work, as it seemed i put the wrong extension on it. So i then went from there with both files now to use to make the omniwheels. As I was going along with that, certain things came up pertaining to our robot (as you see the drive system with the chains, we needed a way to get the sprockets/spacers and such attached to the omniwheels), so I started messing with a few things on the wheels as far as attachment holes. Then we decided it would be nice to personalize them to put some flare on our robot, and thus the text was placed on it. Also minorly changed a few things as far as the size of the spaces for the washers and a few things like that. We used the waterjet to cut out the hubs and washers, got those pins done manually from a long piece of stock, and then put it all together.

I'd like to thank Andy and whoever helped first create them, they work like a charm, a great job on concept and design of the wheels. Personal changes were made so that sprockets, spacer, and bearings could fit nicely into a single assembly with the omniwheels.

Comments of any kind can be directed to me via email or IM. I know i said many times where we got the designs within our group, but i'm a small guy so i guess i just need to be louder. The wheels were partly my project and not the person who originally posted the pictures, so i'll take responsibility for all of it.
