March 5, 2003 - Announcement regarding Toy Radio Controllers.

Any radio control that does not have changeable crystals and that
dosen't operate on the 1991 narrow band FCC channels will not be allowed. And only
ground channels, 27MHz (A1-A6) & 75 MHz (61-90) & 50MHz (if you have the
appropriate license). Anything else is outlawed.

We've had lots of problems with these toy radios. Some toys operate on 27MHz
and typically the users cannot tell me which one of the 27MHz narrow band
channels (A1-A6) or if they are using up all of them. Also, we have have many
interference issues with the toy radios, which is a safety concern.

1/20/03 NOTICE: NEW RULE SET COMING INTO EFFECT FOR ALL FUTURE EVENTS.

In accordance with the RFL, we will be using the official RFL ruleset. The ruleset only covers
the robot itself and not the event or the arena. The goal is to have a standard ruleset for all
competitions so you can easily take your robot to many events without worrying about
major rule changes. We have adapted our existing rules to accommodate the RFL rules.

4.0 Robot Melee

The robot melee is a 3-minute free-for-all battle where the last robot
standing wins. Typically 8 robots will be placed in the arena for each
round. Depending on the number of robots eligible for the melee, at least
1 and up to 4 of the robots will advance to the next melee round. In the
final melee round, one robot will be crowned as the champion.

The breakdown is as follows:

  First Round Second Round Third Round
# Robots Entering Melee # of Heats # Robots in each heat # Robots advancing in each heat # of Heats # Robots in each heat # Robots advancing in each heat # of Heats # Robots in each heat
4-8
9-16

The number of robots entering the melee will be evenly divided into each
heat so that each heat in the first round has roughly the same number of
robots. Robots will be randomly assigned into the heats.

4.1     Pre-Fight
          4.1.1 Robots will be placed evenly spaced around the center.
          4.1.2 The arena enclosure will be made ready to fight.
          4.1.3 All robots must have all electric motors stopped. No external
                   component of the robot can be moving.
          4.1.4 All flame devices cannot be emitting an external flame.
          4.1.5 Operators will be allowed to check their radio by moving the
                    robot without encroaching on the other robots.

                    the round.
          4.2.4 Robots will be asked to stop pinning another robot after 15

5.0 Robot Construction Regulations - SEE RFL RULESET

Note: Due to the arena opening being 13" wide, all robots must not be sized so that it may not fit thru the openings. Therefore, all robots must start the round completely inside the starting circle, which is 12" in diameter.

6.3
Starting Circle Inspection
          6.2.1 Robots will be required show their robot's starting configuration to
                    ensure it can fit within the 12" diameter starting circle.
6.4 Post-Fight Weight Inspection
          6.3.1 A competitor may ask for a post fight weight inspection in which
                    case both robots will be check for weight violations.
