Yes.

Yes, as long as the wire is contained within the enclosure for the
custom circuit board.

Subject: Re: transport

You may transport the robot to the drayage facility (storing area) 
yourselves, but not the event (in any circumstance). This is new from last 
year. The drayage facility information will be posted within the next few days.

A) Yes, you may transport your robot to the local drayage site for 
the 1st regional you attend.  If you are attending subsequent events 
your robot must be shipped from site to site directly. Please note 
ship (out of hands) deadline:  Your robot must out of the team's hands 
-- either in a shipping company's possession, or at the drayage 
company designated for your event by 5p.m. local time on Tuesday, 
February 19, 2002.
    Drayage site arrival deadline:  There is also a deadline for 
robot arrival at the drayage company.  Your robot must be delivered to 
the designated drayage company by 5p.m. local time on the Monday prior 
to your event.  Refer to the web site for the date for the robot 
arrival deadline for each event in which you participate.


If so, where is the storing area for the Cleveland regional and 
contact person?

A) That information will be on the FIRST website 
(http://www.usfirst.org) in a few days.  Please check there for you 
information.

A) The LEDs provided in the kit are for use on the robot or for use on the Operator Interface side of the control system.  They may be used for decoration or to provide useful feedback to your team.  For example, you could use an LED on the driver's side in conjuntion with a sensor on the robot to indicate when your robot has successfully attached to a goal.  You are not required to use the LEDs.

Please specify the worst case spacing construction tolerance
 that may be expected in competition
 between adjacent vertical steel posts
 at the lower level and
 at the higher level (if different)
 for the same pair (deviation from parallel).

A) All tolerances are +/- 1/4".

Subject: Flywheels

Team 842 asks,
     May we use a flywheel as an energy storage device? ie. may our 
battery spin up a flywheel and and use the power from the flywheel to 
power other devices, so long as it does not increase our voltage, amp-
hours, or interfer with the electronics?
Thanks,
Nyy and Team 842

A) No. Robots may not contaminate the balls with lubricants. See Rule DA2.

A) You can use a flywheel, but you can not start spinning it up until 
the robot is enabled at the start of the match.  Please note that if 
it proves to be a safety hazard, the referee will ask you to change it 
 before you are allowed to compete in another match.  Remember that 
when your robot is disabled, the flywheel should not cause any part of 
the robot to move for an excessive lenght of time as determined by the 
referee. More than 10 seconds would be excessive, please see rule SC1.
