WOW,

I honestly didn't think you were serious. I bet this will be a design that raises the bar for swerve drive.

Can't wait to see it.

Re: pic: 254/968 Swerve Modules!

This reminds me alot of the thunderchickens swerve. I know there have been others but I was looking at it reciently so it is the one I think of with this style of single part design. http://www.chiefdelphi.com/media/img...1ddcdbc2_l.jpg

Very cool, I was hoping you weren't kidding about the swerve drive! Can you tell us the dimensions of them? They look pretty small (at least compared to other team's swerve modules).

Re: pic: 254/968 Swerve Modules!

Although I can't think of any other uses for these parts, I am still reluctant to believe that there is a swerve drive in the works. For one, I don't see how the previously posted bearing blocks fit into these parts (and I somehow doubt that 254/968 would spend their time machining a ton of bearing blocks just to throw them away).

Re: pic: 254/968 Swerve Modules!

It's all a part of their master plan. For the past three years, Travis has been posting beautiful photographs that are almost too good to be real. Now people are used to it, so he slips in a rendering, and everyone thinks it's real.

01-31-2008 11:16 PM

Re: pic: 254/968 Swerve Modules!

Well, 254 seems to be building a drive base for a team that shares their shop... So maybe those parts were for them?

Anyway, whatever these end up doing, they sure do look beautiful!

Re: pic: 254/968 Swerve Modules!

How were those machined? Was it an aluminum block milled down?

Maybe it was 1/4in rectangle bar placed in a CNC bender. Either way, those are beautiful pieces.

Re: pic: 254/968 Swerve Modules!

these pieces look more like a universal joint than a swerve module to me. I still think 254/968 and swerve are not to be this year.

Paul Copioli

Re: pic: 254/968 Swerve Modules!

Since they posted a picture I can break my silence. In the Fall, some members of 254 asked me to send them some cross section views of our 2002/2003 swerve modules. Those forks look awefully familiar ...

About the bearing blocks: The swerve forks allow the drive transmission to be remotely located so the bearing blocks could be somewhere else on the robot.

Those forks look sweet.

Re: pic: 254/968 Swerve Modules!

Hmmmm, looking at this picture and knowing 254/968's propensity for making 2 practice robots, are we looking at a two wheel swerve ala Simon? Or a really crazy 8 wheel swerve. Or two sets of 4 four a basic swerve.

02-01-2008 12:35 PM

Ryan Dognaux

Re: pic: 254/968 Swerve Modules!

My thoughts exactly. And knowing these guys, this could be one of the lightest swerve setups FIRST has ever seen.

Re: pic: 254/968 Swerve Modules!

You need to find someone with a wire EDM machine. It would be WAY easier.

02-01-2008 01:12 PM

Mike Hendricks

Re: pic: 254/968 Swerve Modules!

Maybe .. Wire EDM is expensive .. especially for something that thick .. I think in the end, it would just be cheaper to take a ton of fast passes on a mill.

Those do look very thick .. I'm with tdlrali .. thinking 1/2" - what was the size of the raw aluminum? How many ops? Machine time?

Very hot though. And Adam .. I believe we need to have a little discussion

Re: pic: 254/968 Swerve Modules!

Yes the machine itself would cost a fortune... Thats why they need to find someone else to do it for them.

Rather than buying broaches we cut all our keyways with EDM. We recently cut a 6" long keyway!

Re: pic: 254/968 Swerve Modules!

Team 118, which is a NASA team from the Space Center near Houston has done this type of drive before. Check this picture.

02-01-2008 06:38 PM

Michael Corsetto

Re: pic: 254/968 Swerve Modules!

Yes, but 118 as far as I know has always done their coaxial swerves with all four wheels driven by a single gearbox, which doesn't allow for rotating the base, hence why they always have a turreted scoring mechanism. My guess is that poofs/rawc will be doing two gearboxes, improving (if its physically possible) their 2 speed from last year. I just don't see the poofs with a turreted scoring mechanism, doesn't seem like their style. This is all speculation of course, we may see something totally different from the poofs this year, even more so than we have already...

02-01-2008 08:07 PM

Richard Wallace

Re: pic: 254/968 Swerve Modules!

My prediction: 254/968 will have a drivetrain like their larger, more famous NASA cousins. 2008 is a good year for articulated steering. MER steering is awesome.

And MER hybrid mode is even more awesome.

02-01-2008 09:22 PM

bmusser

Re: pic: 254/968 Swerve Modules!

I think you could steer each side or front/back of the drive separately and essentially do a zero point turn or ackerman steering. Take your pick.

02-01-2008 09:38 PM

EricRobodox

Re: pic: 254/968 Swerve Modules!

Why MER when you can MSL?

Re: pic: 254/968 Swerve Modules!

It wasn't us who machined them. But yes, they did turn out very nice though! John had the idea to take the picture on a 968 esque table and have me post them as ours. All of the design and manufacturing was done by them and their buddies. It all turned out amazing!

Their completed robot on the other hand... I was never a huge fan of red.

Re: pic: 254/968 Swerve Modules!

Just to tick Travis off some more... I suppose that this is a good spot to make an official AndyMark announcement:

(official trumpet sound: ta ta daaaa)

All AndyMark AM Planetary gearboxes sold for the next 6 months (or so) will have red-anodized housings*.

The functionality will be the exact same, but with this new red color. We were waiting for Travis to switch his color preference over to blue before we made this move.

Andy B.

* - or naked, with no anodizing (but there are a limited number of these)
