Bumper Qs

Rule <R08> says that 2/3 of the robot must be covered in bumber, the diagram they give has a side that is only partially covered by bumpers. Our design would be improved if one side was completely free of bumpers. Legal? whole robot will still be 2/3 covered by bumpers. Please assist.

Re: Bumper Qs

Well, if it will still be 2/3 covered in bumpers with no bumpers on one side, I'd say it's legal.

Re: Bumper Qs

As I understand the rule, If 2/3 of the perimeter of your robot have bumpers then you are good.

I'm guessing that your robot has 4 sides, if the lengths of the 3 sides with bumpers sum up to 2/3 of your robot's perimeter, then you are fine.

We designed our robot according to this, so the front of our robot will not have a bumper. Please someone correct me if I'm wrong as this would impact our design (not greatly... but still).

Re: Bumper Qs

To my understanding If you have two 38" sides and two that are 27" then your perimeter is 130" then 2/3 of that is about 85.8" so as long as your bumpers equal 85.8" when you add them together your good. I personally think the more bumpers the better unless they block a mounting spot for a manipulator or something.

Re: Bumper Qs

now here's the tough question:

What if you have a fractal bumper on one part of your robot's perimeter, giving it infinite perimter. That way you wouldn't have to cover the rest of your robot in bumpers and you would still be legal (infinity/(infinty + constant) > 2/3)

................jk ;-)

Infinity divided by infinity is an indeterminate, and therefore the legality of your robot is unknowable.

Well, those wouldn't be standard bumpers, so according to the rules you'd be in some trouble...

What they are showing in the picture is that if you partially cover the last side the bumpers MUST be at least 6" long to be legal.

Re: Bumper Qs

I am assuming we cannot use bumpers we made for 2 years ago,
even if they meet the requirements?

I believe that would be correct...but you could always ask Q&A to be sure. Some things are allowed to be reused robot to robot, but I am not sure if bumpers are one of them.

Bumpers are fabricated, not COTS purchases, so they cannot be reused.
