4.7 Fires

For obvious reasons of safety and economy, fires will be simulated by small candle flames.

• The candle flame will be from 15 cm to 20 cm above the nominal floor level.
• The candle thickness normally will be between 2 cm and 3 cm.
• The exact height and size of the flame will change throughout the contest depending upon the condition of candle and its surroundings.
• The robot is required to find the candle no matter what the size of the flame is at that particular moment.
• The candle will be placed at random in one of the rooms in the arena.
• The candle has an equal chance of being in any of the 4 rooms in each of the robot’s trials.
• It is possible for the candle to be in the same room on two of the robot’s trials.

The Candle Location Mode is required in the Level 2 and Level 3 competitions, and it is an option in Level 1. See Section 5.4.0.8.

Additional information about candles and candle circles follows

• The candle will be mounted on a small wooden base painted semi-gloss yellow.
• This base prevents the candle from tipping over easily, but a robot can knock the candle over by bumping into it.
• Judges will give penalty points if that occurs (Section 5.4.4 on page 33)
• The contestants may not measure or touch the candle before it is used. Violation will result in immediate disqualification of the team and the robot from the competition.
• The candle will not be placed in a hallway, but it might be placed just inside a doorway of a room.
• When a candle circle is present it is not anchored to the arena floor. Consequently, it can be dislodged by a decelerating robot. There is no penalty for this, but the moving circle might knock the candle over, and there is a penalty for that.
• A candle circle will not touch the doorway line. Thus, the front of the robot will be able to move at least 33 cm into the room before encountering the candle.

4.7.1 Extinguishing the Candle

The robot must, in the opinion of the Judges, have found a candle before it attempts to put it out. For example, the robot cannot just flood the arena with CO2 thereby putting the flame out by accident.

The robot must not use any destructive or dangerous methods to put out the candle.

The robot may extinguish the candle by blowing air or other oxygen-bearing gas. However, this is not a practical method of extinguishing a fire in the real world, so robots that do not use air streams to blow out the candle can operate in Non-Air Extinguisher Mode for an improved score. See Section 5.4.0.6 on page 32 for details.

In the Level 1 competition Standard operating mode, the robot must come within 30 cm of the candle be- fore it extinguishes the flame. There will be a white 30 cm radius solid circle (or circle segment, if the can- dle is near a wall) on the floor around the candle, and the candle will be placed in the center of the circle. The robot must have some part of its body over the circle before it extinguishes the candle flame. In Level 1 robots may choose Candle Location Mode, which omits the candle circle and minimum distance require- ment. See Section 5.4.0.8 on page 32.

In the the Level 2 competition, the robot may not extinguish the candle until the robot is fully in the room where the candle is located.

In all Levels, the robot must turn on a bright red LED, indicating that it has detected the candle. Can- dle detection is the only event that will cause this LED to be turned on. The LED must stay on at least until the candle is extinguished. The LED must be mounted on the control panel in plain view so that the judge can see it clearly at all times during each trial.

NOTES:

1. It is good design to place this LED on to the control panel, which includes the start switch, sound activation microphone, and power kill de- vice. One possible arrangement of the control panel is shown in Figure 13).
2. Your robot must use individual LEDs for sound activation detect, candle detect, and baby detect. You must use the standard LED colors:
   1. BLUE for sound activation
   2. RED for candle detection
   3. GREEN for Baby Detect LED

Do not use a multi-colored LED.

Robots that touch a lit candle with either the robot chassis or a sensor will incur a penalty as specified in Section 5.4.4 on page 33.
