Re: Frame design question

I was thinking the same thing, Don. Anyone offering to exorcise a possessed ball? Or is it cheaper just to replace it? #5s are too small to be exercise balls, right?

Re: Frame design question

What if frame is seriously convex to the point where it is curves a pocket into itself, like an island atoll and having an opening on the wide side just larger than a ball? Would the bumper have to wrap both the outside and the inside "shore" of the "lagoon"? Could several balls be rolling around inside the lagoon area without being considered possessed, or having penetrated more than 3" into the frame zone? Would all the robot's H/W have to be built up ONLY within vertical space directly above the atoll shaped frame, or could some hardware protrude into the space above the lagoon? Why would there even need to be a bumper inside anyway, since no impact could ever happen there, and only "topologically" it is still the "outside" of the frame?
Kind of tricky getting a shooter concept to fit with this scheme for sure.

You would have to have a bridge across the mouth of the lagoon to attach your bumpers to, to meet <R07-M> and associated Fig 8.3. Note that the balls will still fit under the bumper attached to such a bridge. Therefore if the lagoon is more than 3" deep, you will violate <G46> and <R19>.

I would suggest spending a few more hours digesting the manual before you finalize your designs. You seem to have missed a few key rules.

Any convex part of the frame will not be considered as the frame perimeter, if you have a convex are you want the ball to sit in the ball may only go 3" past the line created by wrapping a string about the corners of your robot, that is what defines the frame perimeter

Re: Frame design question

From the definitions at the beginning of Section 8...

FRAME PERIMETER – the polygon defined by the outer-most set of exterior vertices on the ROBOT (without the BUMPERS attached) that are within the BUMPER ZONE. To determine the FRAME PERIMETER, wrap a piece of string around the ROBOT at the level of the BUMPER ZONE - the string describes this polygon.

The string in your scenario bridges the lagoon and crosses the island.
