In Butterfly drive Omni wheels go unpowered, the use of them if is for drifting around.

Negative sir, they are powered and normally connected by gear or belt.

My mistake. I seem to reamber team 118's robot having passive omni wheels on their Buttyfly drive. The designer of thus drive train is on my team so I can ask him about the unpowered omni's.

Robonauts did have Omni-wheels on their drive last year, but it wasn't anything close to butterfly. They used the omni's in conjunction with their WCD 8wd to perform J-turns and mad drifts.

Actually Robonaut's drive was a subset of Butterfly called Texas Coast, the unpowered wheels are what makes it Texas Coast.

While we're grumbling about what someone else called their bot, we may as well aim for accuracy -

Did the Robonauts call it grasshopper drive, or a subset grasshopper drive? Where's the proof either way? I don't recall them calling it anything other than 'drop down omnis'.

Then again there is no formal definition of grasshopper, butterfly or other insect-based drive. IMO, they're all just derivatives of the Armadillo Drive and none of them ever give it credit. To me, "Texas Coast" isn't a subset of Armadillo Drive since they serve 2 different purposes and are designed quite differently.

Am I crazy? Was there one before 2010? My memory is getting bad these days...

Haha, I get your point. It's just a little bit easier to talk about drivetrain styles when you have some specialized vocabulary.

Also, I thought Tex-coast was a few of the Texas teams feeling left out of the WCD hype train and they tried to rename butterfly.
