A) The small motor is the Johnson Electric motor. The specs will be in Team Update #3 today. It has no mating gears of any sort.

Is the pitch dia. and modulus/dia.pitch of each known? Also the matching gear has two sections, one seems to be a good mate, and the other one doesn't, with indicates it's characteristics are different. Do we know the characteristics of this gear as well? Sam Lindhorst Team #240 A: This information should be in Team Update #2. ________________________________________________________________________ ________________________________________________________________________ Message: 4 Date: Fri, 18 Jan 2002 16:58:09 -0000 From: "frcengineers" Subject: Re: gripping flanges Q: >>When gripping goals, is it permissible to attach to the flanges above and/or below the pipe nipple?

Say for example I was robot A. Do I need to keep my control system in station A and do I need to start my robot in position A? A) The Control System must be located where your Team Number is displayed but your robot can be in either of your allinace's starting positions.

We understand that there is a box that the robot has to fit into, but is it legal to stand the robot on end to fit in this box? Thanks, OHS #396 << A: Sorry for the delay. The *starting* configuration must follow the dimensions laid out as posted today in message 423. The 5' dimension cannot be along the ground at the start of the match. After the match has started, the robot can expand, of course following the expansion rules. We have deleted a number of duplicate posts around this question instead of replying individually to each one. ________________________________________________________________________ ________________________________________________________________________ Message: 9 Date: Fri, 18 Jan 2002 06:12:36 -0600 From: "James Hausch" Subject: Re: Re: Optical Sensors Try www.bannerengineering.com The sensor is the "QS18 WorldBeam" >From: frcengineers >Reply-To: FRCtech2002@yahoogroups.com >To: FRCtech2002@yahoogroups.com >Subject: [FRCtech2002] Re: Optical Sensors >Date: Fri, 11 Jan 2002 20:14:56 -0000 > >Q: >> After looking through the parts checklist, and visiting "Banner >Electronics" website, I have been unable to find documentation on the >specific optical sensors included in the kit. > >Where can I obtain doccumentation on the included optical sensors. << > >A: Look in Appendix G, pg 12-13 for the part specifications. > >-M4 > > > > >To unsubscribe from this group, send an email to: >FRCtech2002-unsubscribe@yahoogroups.com > > > >Your use of Yahoo!

I have sent 2 e-mails giving information required under team update #2 to the e- mail address indicated and still do not have an account number and password so that we can access this information. Has anyone else had this same problem? Thanks in advance Sandra Beall Team 807 Code Blue Robotics << A: The original date for applying to Autodesk (first.entries@autodesk.com) for an id was 12/21. However - honestly - we're not sure that that was communicated clearly enough to teams. A lot of requests have gone in in the last two weeks, and there is a large backlog now. All we can say is, we appreciate your patience and we are directly checking into it with Autodesk. -MW ________________________________________________________________________ ________________________________________________________________________ Message: 13 Date: Fri, 18 Jan 2002 20:06:30 -0000 From: "frcengineers" Subject: Re: broken goal pieces Q: >>If we accidently break one of the PVC tubes (conduit) on the goal by trying to insert or remove a ball, does our team get penalized?<< A: If you didn't break rule GM22, no you wouldn't get penalized. ________________________________________________________________________ ________________________________________________________________________ Message: 14 Date: Fri, 18 Jan 2002 20:35:55 -0000 From: "frcengineers" Subject: Re: carpet damage > A concern has been raised that there is a potential for carpet > bunching.

A) Whatever the venue floor is. FIRST does not put any padding under the carpet. The carpet is placed directly onto the venue floor. FIRSTsnow ________________________________________________________________________ ________________________________________________________________________ Message: 17 Date: Fri, 18 Jan 2002 21:31:23 -0000 From: "frcengineers" Subject: Interaction with the Goal Refer to M6 and GM18. The goal can be grabbed in the area between the upper and lower plywood decks by grabbing the nipples. The flages are considered part of the nipples. The lower surface of the upper deck and the upper surface of the lower deck can be incidentally touched. By this, we mean that it can be touched but if you apply enough pressure to either or both surfaces such that the goal can be pulled or pushed, we consider you attached to this/these surface(s) and this is not allowed. The upper and lower decks have stainless steel edges. These edges cannot be grabbed but the vertical surfaces of these edges can be pushed on in order to move the goal. The goal can be lifted by grabbing the nipples. The goal can leave the playing field surface but upending (tipping over) of the goal is not allowed.

I realize the extent of how intentionally a team makes contact with other robots is a judgement call for the referees, however, I believe FIRST needs to > emphasize the difference between intentional and incidental contact. A) FIRST believes DQ3 is sufficiently clear. There is no question that Referees will have to be well versed in the rules and prevent intentional damage... which clearly is not "gracious professionalism."

From which, either through tones or synthesized voice, gave commands to the driver so he/she could locate goals and/or balls on the playing field.

A) The tape dividing the Zones is Polyken 203 white, 2" wide x 60 yds long. There will be no line dividing the field halves.
