Swerve drive

[Noudvanbrunscho]

For our offseason we want to start work on a swerve drive design.
We have no experience (yet) in this area so we want gain knowledge by talking to swerve teams at worlds.
Who is going to worlds, has a swerve drivetrain and is willing to share information and talk to us?

Greetings from the Netherlands!

We are not technically qualified yet, but we are reasonably sure we will make it to Worlds after this weekend. Stop by team #246's pit and we'll talk about our experience with Wild Swerves from 221 Robotic Systems, which was very positive.

We built Rover in the fall and used that as a coding platform for developing our Swerve Coding Skills. We literally could not have done swerve on this year's robot without that fall practice project.

Cheers,
Joe J.

We've built a swerve drive this year and we will be at champs if you want to have a look at our CAD files.

I think we've made the only 2-speed swerve drive this year

just come by 3360's pit and we'll be glad to help you

Team 234 has a very effective swerve drive this year. Although we're fairly new at having one, "only our 2nd year doing it", we've produced a very efficient drive system. Stop by our pit at worlds and we'll be glad to show you how we came up with it!

2468 has never used swerve before this year. It was one of our banned words not to be uttered in the shop, simply because it was not a solution we had any off-season experience with.

However, this year, due to the availability of a COTS solution and student demand, we opted to permit the use of the AM swerve modules. If I recall correctly, the current iteration of a corner is: am-3009 (CIM replaced with a mini CIM) + 3D-printed position-sensing gear + MA3-A10-250-N encoder + Talon SRX with analog breakout board for steering + Victor SP for drive. We program in LabVIEW.

Feel free to swing by our pit and ask our students of their experiences with these modules (driving them, integrating them, and programming them).

Kudos and our thanks to the Bomb Squad for helping us with the swerve control software.

We are toying with the idea of doing an off season project to design, manufacture, and test our own swerve module.

Swing by team 1323's pit this year for the most compact and lightweight swerve yet.

Perhaps you can back up this claim, I'd love to you see put together an article for beyondinspection about it.

Other teams to look at for swerve at Worlds: 16, 696, 1717

Turn it down a little bit.

I'd like to see pictures, CAD and a scale to back this up. I'm going to guess that 1717 is single speed this year and managed to save some weight out of their already 1st tier swerve.

I hope frc 2451 has one of their swerve modules from last year in the pit.

195 took the AM Swerve (am-3009) and made some simple mods to put it "on steroids".

It for sure isn't the lightest, fastest, or best module out there, but we're pleased with how it came out and how easy it was to integrate.

Feel free to stop by our pit at Worlds to see it and ask questions. We will have a spare module to handle.

We've had a lot of luck with 221's Revolution Pro modules. They are awesome:

It would be nice if we could get a different wheel on there and I suspect custom wheels might become an off-season project for us. Great setup though.

See if you can stop by 1640's pit, they're always more then happy to talk about their swerves. They've been using them for years now and gone through a million iterations. It's really neat stuff.

Edit: by years, I mean somewhere around 6-8 seasons

Since 2010. Drop by anytime! We're also open source on the website.

1640 has an entire wiki dedicated to the development of their swerve modules: http://wiki.team1640.com/index.php?title=Swerve_Central

Start designing yours now so that you have a good list of questions to ask teams when you get to CMP. Write down a list of questions. The first teams that come to mind when people think of good swerves are 16, 973, 1323, 1640, 368, 1717(possibly the best there is), and 118. These teams have all developed a good swerve drive in the past or currently use one that's been in production for several years.

Also, make sure to have some programming questions ready when you get there because that's one of the most challenging parts.

Follow up:

Don't forget 16, their swerve is as good or better than most of the ones you've mentioned. Also, check out 1640 and ask them about some of their more recent control software updates from the past season or two, the way they drive is really awesome. And for a first-iteration swerve drive, 696 seemed to have a really good handle on the process; their system is very cool. 3360 has a two-speed swerve, which is way awesome as well.
