The rules also state that the championship rounds > will be best 2 out of 3 but it does not state how they will be > scored. Will it be best "raw" score or best 3x loser's score? A) In the elimination (finals semi-finals, etc..) rounds, teams will not receive qualifying points. Best 2 out of 3 represents the number of matches won in a series. --- FIRST MRT ________________________________________________________________________ ________________________________________________________________________ Message: 6 Date: Thu, 10 Jan 2002 21:03:02 -0000 From: "frcengineers" Subject: Re: Dragging Opposing Robot > Is it legal to DRAG an opposing alliance robot against its will into your home zone for an additional 10 points? A) Yes, becareful that the mechanism you are using to attach (or drag) a robot can be easily released. Also remember that the 1 minute setup and resetting period will apply, see rule GM6. Will this violate "PINNING" rules? A) No. Pinning refers to holding a robot against the edge of the field or against the side of the goal. See Team Update #1 for rule DQ8. What happens if you damage their robot while dragging them? A) If the referees determine it was caused by malicious behavior, the alliance causing the damage will be disqualified. If the referees determine that the damage was due to "poor Robot design", then there will be no penalty. In all cases, it will be a referee judgement call. ________________________________________________________________________ ________________________________________________________________________ Message: 7 Date: Thu, 10 Jan 2002 20:46:10 -0000 From: "frcengineers" Subject: Re: Other Pieces. . > Could we use something as a TUBE for the balls. . .IE a stovepipe, or > something not explicitly covered on the Additional Parts List? > Or, could we fabricate a tube out of Fiberglass, such that the > difference between the inner diameter and outer diameter is less than > 1/8"?? Please read Rules K1, M9, and M18 regarding what parts you may use to build the robot. You are welcome to use allowed parts, such as Fiberglass, to build a tube with a wall thickness of 1/8" or less. ----- ER ________________________________________________________________________ ________________________________________________________________________ Message: 8 Date: Thu, 10 Jan 2002 21:04:15 -0000 From: "frcengineers" Subject: Re: bumpers > Could we have a skid pad that acts like a bumper but can extend to > act like a brake, be outside the 30"x36"x60" area, and be > removeable? If the device will be outside the 30"x36"x60" robot starting size prior to the start of the match, then it must satisfy the criteria of Rule M18. If the device will extend out of the robot after the start of the match, then it is not restricted by Rule M18. ----- ER ________________________________________________________________________ ________________________________________________________________________ Message: 9 Date: Thu, 10 Jan 2002 21:21:00 -0000 From: "frcengineers" Subject: Re: last year's parts > Stating M15.

Mechanisms may not be reused from previous year's robots." > My question is;" Can we use parts from last year's kit such as: > Air tanks, motors, or Seat Motor Assembly? A) Only if it's in this year's kit and it's the same exact part. Remember that the seat positioning unit are not a part of this year's kit. Also don't forget you can not exceed the quantities per part in this year's Kit of Part list in Team Update #1. ________________________________________________________________________ ________________________________________________________________________ Message: 10 Date: Thu, 10 Jan 2002 21:22:16 -0000 From: "frcengineers" Subject: Re: No-Show > Another scoring Q: > > Regarding SC7 & SC8- Can a no-show recieve a Win?

(Example: if we have three different components > that we will never use at the same time, must we have all three of > those on there at one time for weigh in?) A) No. See M12 & M2. No configuration that would be used on the field may exceed 130 lbs. Each configuration that is to be used on the field must be weighted during Robot Inspection. ________________________________________________________________________ ________________________________________________________________________ Message: 12 Date: Thu, 10 Jan 2002 21:13:48 -0000 From: "frcengineers" Subject: Re: goal weight > In pounds, >How much does the goal weigh?

After the start of a match, a robot may expand outside the 30"x36"x60" starting size. There is no upper limit on robot size after the start of a match, per se, but robots which extend beyond the limits of the playing field risk being disabled. Also, very long mechanisms may present a risk of entanglement and/or be physically flimsy. See Rules DA4, M4, and M16. ________________________________________________________________________ ________________________________________________________________________ Message: 15 Date: Thu, 10 Jan 2002 21:26:39 -0000 From: "frcengineers" Subject: Re: Sprocket and Belt Question. > Our team is considering using snow blower treads similar to those we were allowed to use last year under the '20 feet of timing belt' and 'any amount, any size sprocket' allowances. Is the interpretation of these rules the same for this year? A)This year you can use any size, any lenght belt, and any size, any amount sprocket. ________________________________________________________________________ ________________________________________________________________________ Message: 16 Date: Thu, 10 Jan 2002 21:34:41 -0000 From: "frcengineers" Subject: Re: What constitutes a projectile > I know a similar question has already been asked, but what > constitutes a projectile? If a part of the robot that is tethered is > launched, is it still a projectile even though it has a tether > (assuming it possessed no risk of entanglement)? We are using a "common sense" definition of what constitutes a projectile. The exact determination will be up to the robot inspectors and referees at the competition events. Below is an attempt to provide a formal definition: "A projectile is any object, whether attached or not, that is launched from the robot and continues moving away from the robot by its momentum, typically following a parabolic path as it falls to the surface of the playing field." Note that something lanched at floor level, such that it never truely falls, but rolls or slids across the floor could still be considered a projectile. ----- ER ________________________________________________________________________ ________________________________________________________________________ Message: 17 Date: Thu, 10 Jan 2002 21:43:09 -0000 From: "frcengineers" Subject: Re: On-Board Camera Rules > Are we allowed to mount a camera on-board our robot? And if so, are > there any limitations such as frequency or size? A) Yes, see rule M9. Remember that it can not be used as a driving aid during a match. Therefore, the camera receiver may not be used in the alliance station. The camera would only be used for entertainment value. --- FIRST MRT ________________________________________________________________________ ________________________________________________________________________ Message: 18 Date: Thu, 10 Jan 2002 21:44:46 -0000 From: "frcengineers" Subject: Re: bumper dimensions > The rules state that bumpers may extend 4" in addition to the maximum dimensions of the robot. Is this 4" total added to the dimensions or is it 4" added to each side of the robot? A)This is 4" on each side. --- FIRST MRT ________________________________________________________________________ ________________________________________________________________________ Message: 19 Date: Thu, 10 Jan 2002 21:47:51 -0000 From: "frcengineers" Subject: Re: Playing Field Construction > Which way do the 3" x 3" aluminum angles on the "fence" around the > playing floor face?

A) The vertical side of the aluminum angle will be the inner face of the field border. > The manual says that the face of the 3" x 3" angle is covered by > diamond plate aluminum, but the drawings do not show this? Which is > correct? A) The second paragraph of Section 2.2 of The Game section of the manual is incorrect in regards to the diamond plate. The field drawings are correct. Diamond Plate will only be used on the Alliance Stations. ----- ER ________________________________________________________________________ ________________________________________________________________________ Message: 20 Date: Thu, 10 Jan 2002 21:48:47 -0000 From: "frcengineers" Subject: Re: How many motors are allowed? > If we wanted to use more of one kind of motor than is supplied in the > kit, is that allowed.
