Unless the problem lies in how it would be coded I don't think there would be much of a delay, well at least not anymore than a 6-wheel drive. I may be missing something though.

I think that you would have to really turn them slowly, less than 60 RPM to get a really noticeable delay. because you are only doing a partial rotation it seems like it would reach its position in less than .5 seconds at 60 RPM no matter what?
No offense, but if you've ever driven the robot around much, a half second delay really screws with your mind. It's like the hot shower phenomenon, where you turn it up a little bit, nothing happens, so you go a little bit more and more until WHAM, the robot goes flying. However, if you program it right you'd only get a quarter turn at once maximum, so if they turn at any real speed, it'll probably be about .05 second delay, which isn't noticeable. Huh, full circle, I guess you're right

I will add on that if the program lets you start rotating the wheels before they're in position, it will go a little wonky until they get straightened out, which could be weird.

4 CIMS and then 1-4 banebots/what have you. And it's not like the metal doesn't weigh anything; for a 6WD, there's basically just two gear boxes, then the six wheels and chain, a swerve drive has four gear boxes (more if there's gearboxes on the wheel rotators), and then supports for each wheel. I'd estimate an extra 10-15 lbs for a swerve drive. Then again, I've never really even seen one
