Swerve drive
 

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!
Team Rembrandts 4481

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!

Re: Swerve drive
 

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.

Re: Swerve drive
 

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

Re: Swerve drive
 

Turn it down a little bit.

Re: Swerve drive
 

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.

Re: Swerve drive
 

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.

Re: Swerve drive
 

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.

Re: Swerve drive
 

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

Re: Swerve drive
 

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

Feel free to stop by 4143 MARS/WARS pit. We are a 4th year team but have multiple iterations of home-built swerve designs (have previously posted CAD for one of those iterations, a search on CD should find that post) and have used swerve each of the past two years in competition. Happy to talk about pros/cons, software, and team #chainless or team #slipring (hey bombsquad). Grab any student in the pit.

Edit: I'm not involved in coding, but if memory serves Bomb Squad's code was something we started with. Still appreciated. By the way, bring back #mercotac.

hey mars/wars

Feel free to stop by and talk to us as well. We can't get enough swerve. :)
