Re: New size/bumper rules that every team should know

Teams will have to be careful to either build robustly, or be well inside the bumpers.

Bumpers may or not actually provide any protection.

This makes the real volume less than the stated volume.
It doesn't seem very different to me in terms of protection.

Two minimalist, full size, box-on wheels robots will still collide bumper to bumper, with 6" between the internal parts of their robots. Of course, now they could hypothetically expand into the 3 inch region directly above, but not beyond, the bumper in any direction, but they don't gain much by doing this. On the more extreme end, teams that voluntarily build small can reach beyond the bumper. The rules of the past few bumper games still apply -- you put mechanisms beyond your frame perimeter at your own risk, and are penalized if one of them reaches into the protected frame perimeter of another team.

It's dramatically different in terms of the size you should build your robot if you want to expand though, and that's why I brought this up. I expect some teams to build very, very small bases which expand a great length in multiple directions, perhaps even with drivetrain components on the expanding parts, and don't want teams to be caught off-guard that this is not only legal, but that their "standard" drive base designs may prevent them from adding these features.
