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. -RRLedford |

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. |

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. |

It appears that the rules clearly are meant to discourage curves in general, and all but the shallowest of concave perimeter shapes in particular. -RRLedford |

And convex curves in general are not prohibited; see http://forums.usfirst.org/showthread.php?t=13723 As for concave perimeter shapes, the only place you can't have them is on the frame perimeter and anywhere you think a ball can get into the lower frame perimeter more than 3". One thing I might suggest for next year's rules is the changing of the word "string" to either "stretched string" or "rubber band", as a number of people have thought the same thing. |

Re: Frame design question
Dick,
Where in Chicago are you located? Perhaps we could meet or I can come over and explain some of the nuances of this years game to the team. Just PM me and we can see what we can set up. |
