I gotta agree. I held a quarter up to it... It's just barely larger than life in the picture.

You better let us in on test results on this one...

Love it, love it, love it.

You should get a shot of the mini next to one of your full size boxes from last year (if you still have an extra one lying around).

Great job.

Really nice job, guys!! Can't wait to see these on a test chassis!!

*double take at picture with quarter*:ahh:

Wow. That's extremely impressive, way to push the creative envelope. I can't wait to see more on this module in the future.

thats extremely awesome! solving the problem of swerve modules being WAY too heavy!! Very cool!

Now this might be a stupid question, but my team has never worked with modules like this, and I'm hoping to actually get my team into it. But how does the module stay mounted in place? Like, what keeps it in its place and allows it to rotate? some platter bearing? I guess i just don't see it... Thanks in advance for answering that! :)

Wow!! that picture with the quarter just freaked me out how small these are... I guess my only concern would be with what they are rotating on seeing how small they are... These wheels are super impressive and have my mind spinning with new ideas...

I'm pretty sure the current rendering has the lower disk nested in a complementary ring of delrin or the like which is mounted to the frame. Three of our members (including Dillon) are currently on a camping trip. Dillon's mom got a call today letting her know that they're working on designing a drivetrain for next year's game.

If these wheels dont hold up you could look into making your own tiny wheels and pouring urethane tread on them like 125 did in 08. I think colson makes some pretty tiny wheels as well and they would definitely hold up much better.

Would that be the water game, the flying game, or the Martian game?

Why would you go camping to design the drive train... wait a second it's a GAME HINT! :yikes:

These will have a thrust roller bearing at the top that can easily handle the load these'll see, pushing up against a flat plate bolted to the frame, at the bottom a delrin or UMHW right will encircle the disc of the module.

Dillon does have a frame cadded up, but as of now we do not plan on completing a full prototype for money reasons. We will on the other hand be putting this on a setup with an old chassis and 2 casters and seeing how it lasts durability wise at the very least.

Have you looked into using Teflon sheets? That stuff is pretty awesome compared to UHMW :rolleyes:

ahem, If you do use these wheels, never spin them on carpet. The tread kinda leaves in a unelegant fashion (ow).

We'll be pursuing colsons and also the prospect of making our own

Not pretty :ahh:

I'm thinking Baltic Birch wheels with riveted Roughtop tread for production, or whatever wood you can find for prototyping in the meantime. You could make them whatever diameter you wanted to, however wide you wanted to, and it would be one solid wheel.

This also shows the rest of us that the BB wheels probably wouldn't hold up very long in an overall FRC season for a defensive-type bot.
