But, I can just as easily picture a situation where a robot touches all of the totes with a mechanism at match start, pulls them toward each other in a known and predictable way, stacks them, and carries them into the Auto Zone and sets them down. Not that my team is planning on building that mechanism, but the stack can be made without moving the robot in (as a guesstimate) 5 seconds. Then drive forward and set it down. 20 points in 8 seconds. Boom done.
I know my team has struggled with the change. It's pretty dramatic, really opens up possibilities, but also takes effort to shift the frame of reference.

Yes, that's true--you could. But "120 lbs" and "twenty-foot robot" are not things I expect to see, at any point, by any team. The teams that could pull it off won't, because they know the value of the containers on the step (which you won't be able to go get in any realistic manner if you're already 21' wide)...the teams that can't pull it off, well, can't pull it off.
[You also don't need vision tracking, if you know where the totes are (which you do) and you know where your robot starts (which you rather should.) Encoders and maybe a gyro should be sufficient.]
