Bumper height v. height of "the bump"

[smcmahon]

Assuming I read and understand everything correctly:

Robot bumpers ought to be 5" tall, and must sit between the bumper zone of 10" - 16" from the floor. So bumpers would ride at their lowest from 10" - 15" from the floor and their highest at 11" - 16" from the floor.

"The bump" starts it's angle at the floor and tops/levels off at 12" from the floor.

So isn't it the case that everyone's bumpers will actually be higher than "the bump"? Significantly high on the top anyways? The robots in the demo video don't seem to be designed this way, although I 100% understand that video is just to get the idea across... for reference.

Since the wheels cannot extend outside of the bumpers, this is creating a funny picture in my head of a robot trying to successfully climb over "the bump"... I always sucked at math, so I guess the angle of the actual "bump", floor to top, is well designed to allow robots to climb it without having their bumpers get in the way. I dunno... I can't wait to get a practice bump built so I can see this first-hand.

Does anyone know the angle of the "bump" sides, floor to top?
