I’d assume it’s some of the other types of drivetrain; I think what I’ve seen this year in data are H-drive and Butterfly drive. In my spreadsheet other also includes mecanum drivetrains.
There are probably some 15 teams at Milford with swerve.

I’ve updated the spreadsheet with the data here. I decided to include the approximate data, but I marked it as such in the spreadsheet. If anyone has specific numbers that would be great. Here’s the current numbers:

You appear to have 54 teams of data, but TBA rankings show 55 treams ranked. Do you have any idea what drivetrain the last team had or who they are?
Counting is hard, reverified the numbers and the original post is now correct

Thank you!

Our scouting has 13 listed, but it it’s not complete. I’ll check in with another team and post that here.

3492 had tank treads, 3484 was octocanum, and 6834 had h drive.

You can add 5503 as a tank in FIT…ran Waco and Belton.
Out of curiosity, how did you switch to tank in the middle of the competition?

We sheared a carrier plate in the sport gearbox driving our arm, swapped to an extra, and quickly broke that one too. MARs was gracious enough to give us a versaplanetary replacement, but we figured that was going to break anyway so we just swapped out the drivetrain and played defense. It helped a LOT on the charging station though, although the mecanum seemed fine unless you were misaligned a little, then it would start careening all over the place.
EDIT:
Misread the question as why we switched. We didn’t switch to a true tank, although we’re in the process of doing that now, but we swapped the code and the front wheels to traction. We kept the rear wheels as mecanum because it allowed us to turn much more easily.
One of the bots at FLR was a jump/butterfly drive. Might’ve just been incorrectly reported as mecanum.
That could have been. My scouts only had the options of swerve, tank, mechanum, or other and it wouldn’t surprise me if they looked and went “close enough”. I never had the chance to make it through the pits myself to verify everything and I wasn’t always paying close attention when they were on the field.
I’m going to choose to assume that’s the case. It seems more probable than it being called swerve or tank and I really don’t have a way to verify without looking up every team.

No worries. I was able to track down 329 (Swerve) and 333, 334, and 6401 (Tank) on social media so I’ve added those to the totals. I’ll probably go watch some match videos at some point to try and ID the rest.
I know for sure 3492 ran a skid-steer drive with tank treads. Unsure about the others.
