According to the bumper rules it says that the bumpers must cover 2/3 of the perimeter of the robot. Would that be the perimeter of the bottom of the chassis or the max length and width of the chassis?
My opinion is that it means 2/3 of the perimeter of the robot within the bumper zone.
Warning: My opinion is worthless at inspection.
Don
it’s max length and width
look at fig. 8-2 (page 11, Sec. 8) in the rule book

I agree with the last person about the inspection
Good Luck
yea cause our top half of the robot extends about 4 more inches then our frame so i was not sure if the 2/3 applied to the frame in the bumper zone or the entire robot.
It’s the “exterior perimeter”.
I’d interpret that to be something like perimeter of the bounding box (if we’re talking about rectangular robots). If the shape is more complex, I would wonder whether the intent is for the rule to apply to the convex hull shape that encloses the robot, or if there’s some other criterion for defining what’s an exterior feature, and what’s an interior feature (and not included in the perimeter). I’d be inclined to accept any good-faith attempt that satisfies the 2/3 stipulation by some obvious metric.
You’d certainly have a problem if you had a C shaped robot… if of course it literally required 2/3 of perimeter in that sense.
