The spread of pinching rollers this year

[AdamHeard]

I know it isn't that uncommon for teams to change their design once they've seen other teams, but I feel like this happened moreso this year with the pinching roller intake than any other mechanism any other year.

To be clear, I'm referring to dual horizontal rollers, one above the ball below. In most applications the bottom one is fixed so it can't rotate, and the top has some sort of clutch or current control.

I'm curious to hear who had the design idea initially, and who added it later, and if so, who did they copy/get inspiration from?

I guess it's common knowledge that "Team IFI", 148, 217, 254, 968, 1114 and 2056 all had the design at ship time.

We added ours a week or so after ship mostly from inspiration from 148's video.

I know 971 added theirs after ship but before the San Jose regional and was inspired by 254.

I know 294 added theirs after San Diego but before Los Angeles from us, inspired by 148.

It'd be interesting to track the entire spread of it.
