Friction drive worked on minibots because it was such a low torque application, you would need to provide substantial normal force and need a much harder tread material in order to transfer the CIM torque to the wheel through friction, essentially making everything really inefficient.

This a clever little module.

If I recall FRC 141 Wo-Bots did a CIM in the wheel swerve drive last season. It was based on a larger wheel, but it was equally awesome.

Of particular note was that their design used only timing belts and was nearly silent while moving...it was kind of ominous when you were near it on the practice field.

I don't often post on CD, but when I do it's on threads where the engineering genius blows my mind.

cool!

Do you have pictures of that?

I also Saw this beautiful design, all anodized and powder coated, it turned me on, yes, I am attracted to good engineering, to bad I didn't get any good pics.
I wish 141 would post either their cad or a close up of the module.

[wo-bot 141]

i don't have a cad drawing or a picture of it, but i will try and get one for you guys to see.

This would make me, and much of chiefdelphi, very happy!
That design was really a work of art! Too bad we weren't able to win that semi finals match with you guys last year, you are really a great team!

Does anyone have video of this bot in action?

Going to be rare due to GDC ruling about the robot's tactics. Keep looking. Swerves are fun to watch, even when only practicing. It's like being envious of Gene Kelly or Fred Astaire. Maybe I'd like to dance like that, but only two chances of that - very slim and none.

This is a match that has 3928 with a superstructure on top. It's mostly of the other alliance, but there is a coopertition bridge attempt at the end. Uncertain about the outcome 'cause they were still rockin' when the video cuts off.

Its not at competition, but here is video of the swerve in our shop.

Now I'm even more impressed. That looks like a drivetrain that is well built, and can easily beat any 6 wheel drive, without even using the regular swerve mode.

Very, very slick. An awesome piece of engineering!

I just posted video of FRC Team 3928 Neutrino first match EVER!
You can see their swerve in action.

To the Neutrinos:
I have several of your matches in HD video.
Someone can contact me or Carrie and I can eMail them to you.
