So uh yeah... How 'bout that lap counter? Also Metallica.

I believe the lap counter will be supplied by someone at the events.
Seem to remember reading in the rules it will be attached at the start of the match.

Metallica should never be considered noise!

<R18> 
ROBOTS must use the LAP INDICATOR provided by the field personnel
during all official tournament MATCHES. The LAP INDICATOR is attached
to the stopper on the flag pole.
When the FLAG is placed in the flag holder, the stopper will insert
into the top of the holder.  To accommodate the LAP INDICATOR, the 
area within a minimum 180—degree horizontal arc around the top of the
flag holder must be kept clear of any obstructions within a 2-inch radius.
This region must be kept uncovered and visible from above. To ensure that every
FINISH LINE CROSSING is properly recorded, the LAP INDICATOR must be visible to the
Lap Detectors when the ROBOT passes under the OVERPASS. The LAP INDICATOR is
powered via a standard three-wire PWM cable. An easily accessible, powered, male PWM
connector must be located within 4 inches of the LAP INDICATOR mounting location. The
port may be either a direct connection to an analog or digital port on the Robot 
Controller, or a remote “pigtail” connection to the Robot Controller port.

Hear hear!

Now how neat would it be to supplement a "gentle bump to pass" with the "aaaaaooooooooooooogaaaa" sound of a horn? I actually think such a device, if able to be heard over the din of the match without being a painful noise, would serve as an additional useful signal to let teams (and more importantly, referees) know that a bump request has been made.

<R02> doesn't explicitly prohibit the devices; however, if they are deemed to be too loud or are used too frequently to annoying or distracting effect, a team may be prevented from using them.

<R02>
Items specifically PROHIBITED from use on the ROBOT include:
Shields, curtains, or any other devices or materials designed
or used to obstruct or limit the vision of any DRIVERS and/or COACHES
and/or interfere their ability to safely control their ROBOT.
Speakers, sirens, air horns, or other audio devices that generate
sound at a level sufficient to be a distraction or hindrance 
affecting the outcome of a MATCH.

Does anyone else wonder about the field of view on these ir lap counters? and what might happen if say another robot were in between you and the counter, or you are right next to the wall ect.?

There's a thread started already with some details on these things:

i wouldn't worry too much about the counters. the should work pretty well. they've probably takin' that into consideration already.

if you play metallica from your cart, you would be ok, but the robot would be awesome

Sadly, no music is allowed on your carts either! Its not allowed per section 3.3.6 and 3.9.12: "Do not add music to the cart".

If I had to guess I'd say they'll also have refs at each line doing hand counts of robots that cross, the indicator is meant to be a way to keep a fairly accurate score on the scoreboard during the match, sort of like the counters for balls through goals in "Aim High".
