IRI Rule Changes - 2008
In an effort to minimize the changes to the official game, but also to recognize a few areas where we feel the game could be enhanced (based on the beauty of 20/20 hindsight), we are making the following changes to the official FIRST Overdrive rules. All other rules will be intact.
1. For the lane dividers only, a robot has to completely cross back over the lane divider to be penalized. There is no change to the rules regarding the start / finish lines. Multiple line crossings will acrue multiple penalties. 2. Scoring will be based on robot and ball position when they have come to rest, not when the clock expires. In general, this will be 3 - 5 seconds after time has expired. 3. Alliances will be comprised of 4 teams, with each alliance captain selecting their own "back-up. Draft order will be 1 - 8, 1 - 8, 8 -1. Use of teams in matches is completely at the discretion of the aliance captain. (i.e. there is no requirement for each team to play a match). These rules will be "formalized" and clearly explained before matches begin at the IRI. As in the past, teams also have a 'honorary' 5 pound grace for the robots. There will not be a weigh in or inspection, but if a robot is suspect the referees retain the right to require verification of size and weight. |

On the topic of the rule changes, I really like what you guys have done. This will probably eliminate 90% of the silly G22 infractions while keeping the game unchanged. I also really like the "comes to rest" variation. I was a little puzzled why the game this year was decidedly different on what seemed to be a rule that has always existed without problem. |

Re: IRI Rule Changes - 2008
Although we got permission last year, might as well ask now in case we get invited: Can we run non-functional decorations from another power source? (aka: Can we put a camera onboard the robot that uses its own battery?)

Will there be a webcast of IRI this year? I don't think I'll be able to make it, but I'd love to watch.

Re: IRI Rule Changes - 2008
I know its not your robot, but you're looking for something like this?
If I understand 190 correctly, they sit in the homestretch, having never crossed the finish line, therefore the only line that they actually cross backwards is the lane divider prior to their homestretch (only with their arm). I'm not official, but it sounds legal to me with the rule update =) Now that the non home stretch quadrant refs won't have many line violations, you all better play nice and watch those G37 penalties! |

How about extra points for hurdles during hybrid mode?

IRI is always on top of tweaking the game just right to make it the best it can be. I think all of these rules will make IRI as amazing as ever. |

Nope, hybrid mode is already heavily weighted enough. AB |
Re: IRI Rule Changes - 2008
NOTE REGARDING IRI RULES AND INTERPRETATIONS -
Andy Baker is Head Referee and has the final decision on rules and interpretations of rules. The default assumption should be whatever the FIRST ruling was, the IRI will rule the same way. If you have a particular question or concern, contact Andy directly or post it here for a ruling. If the response is not from Andy, it doesn't count. ;) |
Re: IRI Rule Changes - 2008
I so wish our team could go...:D

Re: IRI Rule Changes - 2008
Just looking for a clarifification on the following scenario. Red team places a red trackball at the end of the match, but the red team is still touching the red trackball when time expires. Will it count as placed and recieve the bonus or will it not be counted? or are you going to be looking at if the ball is being supported by the red robot? just a question that I have been wondering about for a while now because it was called differently at different regionals that I attended.

At the end of the match, when the balls and the robots come to rest, if the red alliance robot is touching the red ball placed on the overpass, then the bonus points do not count. During the FIRST season... This determination was made at the sound of the buzzer at the end of the match. If the red robot was touching the red ball at that sound, it did not count. If it was not touching at the time of the buzzer, the ball would count regardless of where the robot came to rest. Andy B. |

Team 1519 would also like to put a camera on our robot to get footage like this (Speed Racer - 10 Laps in 60 Seconds). Would such a camera be allowed? |
Re: IRI Rule Changes - 2008
Since it was never called in Official First Matches I will ask if G40 will be called when a robot is purposely maneuvering in front of another robot. Although an open path may be there since a robot would not block the whole with of the field they would however move to "block" the path when you try to take such path. I've talked with many of Refs about this and I would like to know how it wil be approached at IRI this year.

I think this is a cool thing, and it has been allowed before. I just don't want to open a door that gives a team an extra advantage. Please show me your camera setup once you get to IRI. Quote:
Once impeding (and this could include the active blocking method as stated by Rupnick) starts to take place, the nearest quadrant ref will begin a 6 second count. Once the 6 second count is over, then the G40 penalty is assigned. In many cases, the robot trying to block the other robot will cease their action after a 4 or 5 count. This is not a penalty. The penalty is assigned only if the count reaches 6. The difficult thing to call here, from a referee's perspective, is when to begin the count. We will be watching closely for this, as teams got better at blocking and playing defense as the 2008 FIRST season matured. See you at IRI, Andy B. |

Can we get "80 inch" penalties after things come to rest at the end of a match?

Re: IRI Rule Changes - 2008
These IRI rule changes will be posted on the IRI website soon, and they will be briefly explained at the opening ceremonies on Friday, July 18.
Once again, we aimed at not changing the game. We only are making slight changes to the rules after witnessing the playing of the 2008 FIRST Overdrive game. Here is a listing of the official 2009 IRI rule tweaks: (I hope the verbage is correct and I am not leaving any loopholes open with these descriptions - PM me with suggestions if you see a glaring mistake) 1. Regarding G22: For the lane dividers only, a robot has to completely cross back over the LANE MARKER to be penalized. There is no change to the rules regarding the FINISH LINES. IRI G22: "<IRIG22> Direction Of Traffic – ROBOTS must proceed around the TRACK in a counter-clockwise, direction. Once a ROBOT has CROSSED a FINISH LINE, it shall not break the plane of the line by moving in the clockwise direction. Once a ROBOT has CROSSED a LANE MARKER, it shall not cross over completely in the prior quadrant in the clockwise direction. A PENALTY will be assigned for each infraction." INTENT: The intent of this rule change is to loosen up the G22 constraint at the location of the LANE MARKERS at the ends of the field, but not change the game. 2. Regarding G14 Scoring will be based on the ROBOT and TRACKBALL position when they have come to rest, not when the clock expires. IRI G14: <G14>When the MATCH ends, each TRACKBALL that is at least partially supported by the OVERPASS and not in contact with any ROBOT of the same ALLIANCE will earn a 12-point bonus. All scoring situations of TRACKBALLS and ROBOTS will be evaluated at the point when all TRACKBALLS and ROBOTS come to rest. INTENT: The intent of this rule change is to not take a "photo finish" of the robot position at the end of the match. All scoring will be done at the point when the robots and trackballs come to rest. example 1: If the buzzer sounds at the end of Hybrid mode, and then a robot passes over a LANE MARKER, then the robot will earn the 4 points for passing that line in Hybrid mode (the same thing applies to penalties) This would also be the same at the end of the match example 2: A robot places a trackball on the overpass at the end of the match, and the robot is NOT touching the ball during the time of the buzzer sound. Then, immediately after the buzzer sound, the robot's arm drifts onto the ball and IS touching it after the robot comes to rest. The 12 point bonus for this ball is NOT counted. 3. 80" rule - after the match is over Since we are counting the robot position after the buzzer sounds, we need to make an alteration to Robot rule R16. IRI R16 <R16> Once the MATCH has started, the ROBOT may assume a PLAYING CONFIGURATION that exceeds the size dimensions specified in Rule <R11>. While in the PLAYING CONFIGURATION, the ROBOT may expand up to a maximum horizontal dimension of 80 inches (e.g. all parts of the ROBOT must fit within an imaginary 80-inch-diameter upright cylinder). After the match is complete, the ROBOT may come to rest outside of this 80 inch cylinder, as long as no advantage is gained by this movement. There are no height limits for a ROBOT in its PLAYING CONFIGURATION at any time after the start of the MATCH. 4. At IRI, rule <G53> can be disregarded. Simply put, mentors can discuss issues with the head referee. 5. Elimination Alliances will be comprised of 4 teams, with each alliance captain selecting their own "back-up" alliance partner. Draft order will be 1-8, 1-8, 8-1. Use of teams in matches is completely at the discretion of the alliance captain. (i.e. there is no requirement for each team to play a match). Andy B. |
Re: IRI Rule Changes - 2008
Is Wildstang Recording IRI?? I am coming down agian this year, and would be willing to record the video feed. Andy, or anyone else involved with IRI let me know and I'll bring my recording equiptment with me.

Re: IRI Rule Changes - 2008
Did you folks consider modifying the lap scores to possibly N, where N == the lap #, i.e. 10 laps is worth 55? The intent being to make lapbots competitive with hurdlers. And to finally break 200 :D
Just wondering... :-) |
