Re: pic: Carmen week1 team 842
We will use differential steering on the rear wheels in the code, thats the programmers area, we are the builders, so thats all I can explain

Re: pic: Carmen week1 team 842
I have a vested interest in finding out whether this chassis design is legal. It would seem that the bumper rules require (1) that exterior corners are protected by BUMPERS on both sides and all trailer contact is bumper to bumper, and (2) that bumpers can only be attached to the BUMPER PERIMETER.
Unless I'm missing something, both of those conditions cannot simultaneously be met for the front of this robot (Which may or may not be the GDC's intention. Considering that this picture was posted in the Q&A and all that the GDC said was that exterior corners must be protected, it seems like this particular contradiction hasn't occurred to them.) |

I think it has occurred to them, but they don't answer questions directly, they let you figure out the implications for yourself.

Re: pic: Carmen week1 team 842
Fredi,
The robot looks great so far. If you are intending to place 6" of bumper on the internal, angled side then I think you are meeting the intent of the rule. However, the rule as written as a few wierd nuances that may get you in trouble. Here is what I suggest: 1. Write another Q & A showing the exact picture of your robot with bumpers on all sides you intend to place them. 2. In the Q & A clarify theat the bumpers are all made per the BUMPER rules (plywood, etc.) 3. Specifically ask if the BUMPERS on the angled internal sides are considered BUMPERS or not. Ask if they will be considered in the robot weight or BUMPER weight. What troubles me is that the bumpers on the internal sides are not really legal BUMPERS becasue they are not mounted to the BUMPER Perimeter. My question is how can you cover all corners with legal BUMPERS if one side of the corner is not part of the BUMPER PERIMIETER? Good luck with getting clarification. WE decided to go traditional wide body becasue we do not have the patience to deal with non-answers from the GDC on such a mundane subject such as bumpers. Paul |

Paul, My interpretation has always been that an "exterior corner" is one with both both edges (aka sides of the corner) on the BUMPER PERIMETER. This interpretation would be consistent with the images and text in Update #2. I'm working on getting our password to post in the Q&A. Does this interpretation seem reasonable to anyone else?

An entirely reasonable interpretation, in my estimation, would be to allow 842 to mount non-standard bumpers on the angled pieces such that with the standard BUMPERS on the side the corners are fully protected. The angled pieces would have to count in the robot size and weight. Whether that reasonable (IMO) interpretation will pass, well I guess it's up to them to gamble or not. And the GDC is fond of saying, "We do not comment on particular robot designs. Here's the rule." Last edited by GaryVoshol : 12-01-2009 at 11:28. |

However, reading the rules and looking at Carl Hayden's robot, I see where my definition falls apart. If their bumpers on the front corner are not exterior vertices, then they have no BUMPER PERIMETER. Yup, I was wrong. ![]() |

Re: pic: Carmen week1 team 842
From the rules, it is difficult to tell if this is legal or not.
Either way, though, have you considered this - If you add the bumpers to these angled sections, you effectively make the hole in your chassis about 6" narrower - each bumper is 2-1/2 - 3" thick, and they would extend into this opening area. Depending on how wide the opening is now (hard to tell from the picture) it might become very tight for a 9" game piece. You might actually have a larger opening by having the front of the robot "flat" with 6" bumpers on each side, giving you a 16" wide opening. I don't know how this fits in with you ball pick-up ideas, but something else to consider. |

Re: pic: Carmen week1 team 842
Translation: Carmen as shown in the first post is not legal and has no hope of being legal without relocating the angled sides. That stinks.

Re: pic: Carmen week1 team 842
This is kinda off topic but how did you direct connect your toughbox to your wheel??
and does it have bearings in it? |
