1.0 CONTEST OBJECTIVE

The specific goal of this contest is to build a computer controlled Robot that can move through a floor plan structure of a house, find a red Light Emitting Diode (LED) "Candle", that represents ahouse fire, and extinguish it by covering the LED "candle". This must be done in the shortespossible, subject to a few operating factors.

NB: Throughout this proposal where the term extinguishing the fire is used, it refers to covering theLED.

1.1 THE HOUSE FLOOR PLAN STRUCTURES AND FEATURES

1.1.a. The official floor plan structure is shown in Attachment A. This is what the contest platforlook like. However, just as in the real world where there is always a measure of uncertainty information, the dimensions in the Attachment A floor plan are approximations. The actual dimemay vary up to as much as 4% from the given values.

1.1.b. The walls of the structure will be made of wood and will be 23 cm high and 2 cm thick. Thewill be painted with flat black paint. The floor of the arena will be a smooth, wooden surface painteflat black latex paint. Any seams in the floor will be taped over and painted with the same flat blacpaint.

1.1.c. As noted in Attachment A, all hallways and doorways to rooms will be 23 cm wide with a tolof 4%. There will not be a door in each of the doorways, just a 23 cm opening. There will be a 1wide line, made of Tartan General Purpose white tape, across each doorway.

1.1.d. There will a 1.9 cm line made with same white tape running down the center of each corepresented in Attachment A by black broken lines.

1.1.e. The Home area is a 21 cm x 21 cm square box enclosed by a 1.9 cm wide white tape, as shAttachment A by red broken lines.

1.2 ROBOT CONSTRUCTION MATERIALS

There are no restrictions on the types of materials used in the construction of the robot. Howeveryears past all hazardous, explosive, toxic, etc., materials will be banned. Note that the final designbe able to reach Jamaica. Possible solutions could involve shipping in advance so please i



transportation in your planning.

1.3 FIRE EXTINGUISHER (i.e, The Cup)

A common plastic cup (see Attachment B) will be used to cover and extinguish the fire (i.e., thcandle). Each team will be supplied with an official cup at the start of the competition. The cup mflush with the floor to complete the extinguishing operation. If the design topples the candle, thisbe considered as spreading the fire thus being disqualified for the rest of that run.

1.4 THE LED "CANDLE"

1.4.a. The CANDLE will be represented by a cylindrical object (see Attachment C) with six (6) red Lilluminated. The LED used will be a Red Ultra Bright, water clear case Part # 156970. The distributothis part is LEDTECH but you can obtain information from www.jameco.com. The exact model and psource for the LED can be obtained from www.jameco.com online catalog.

1.4.b. The LED "CANDLE" will be portable and could be in any of the four rooms. The location will bthat there will be sufficient clearance to place the cup over the LED "CANDLE" as specified in sectiHowever, the LED "CANDLE" will be in only three possible locations to be announced at the Cameeting at the start of the contest. Teams should design accordingly. Each team will be guarantethey will see the LED "CANDLE" in all of the three locations at the completion of their threeHowever, the exact order the team faces will be unknown. The LED "CANDLE" has an equal chabeing on, in any of the four rooms, in each of the 3 trials. For each trial the LED "CANDLE" will bethe same room for each participant, thus every Robot will have the LED "CANDLE" on in 3 differentfor the duration of the competition.

Robot builders should be aware that many modern film and video cameras transmit infrared (IR) lpart of their automatic focusing systems. Ambient lighting in the contest room may also be a sourcevisible and UV light. If a robot uses light sensors to find the LED or detect walls, the builders shousteps to prevent these lighting conditions from interfering with its operation.

1.5 THE START OF THE GAME

Contestants will be permitted one minute to bring Robot to track immediately followed by a hawarning. An audible starting signal 1500Hz will sound anytime within a 30 second period after hanThe Robot should begin movement, and at this point the three (3) minutes period will begin audible sound, NOT when the robot moves). A random selection of numbers will be used to determorder in which each robot will run.

1.6 THE RETURN TRIP

1.6.a. After extinguishing the candle, the Robot should return to the Home Area. It does not hretrace its path in returning to the Home Area or even take the most efficient route, it must just gebut without entering any other room along the way. In other words, once it has extinguished the it must leave the room and return to the Home Area without entering any other room, other



penalty of -15 points will be incurred for each room entry.

1.6.b. The Robot will be considered to have returned to the Home Area if any part of it is within cm x 21 cm Home Area. The Robot does not have to be in the same position that it was in when it sthe contest, it must however, have some part of its body within the Home Area (across the tape).

1.7 ROBOT OPERATION

1.7.a. The Robot must be autonomous, that is, once the Robot is turned on it must perform the taslocating and extinguishing the candle by itself. No human intervention is allowed after starting.

1.7.b. The Robot is considered to have entered the room when all its parts have crossed the white the doorway.

1.7.c. The Robot must enter via the doorway of the room in which the candle exists, in orextinguish the candle.

1.7.d. Once the candle extinguisher has been placed over a suspect candle, it must be released. Ta design cannot visit all three locations and deploy the fire extinguisher. The penalty for tryinapproach will be -20 points for each deployment.

1.7.e. Any Robot that damages the playing surface intentionally or unintentionally will be disqualifie

1.7.f. Touching or following the walls of the house will be permitted but discouraged by a ppenalty of -5 points.

1.7.g. The Robot must be able to fit within the 21 cm x 21 cm x 20 cm (W x L ) Home Area (a 21 20 box will be used to determine if the robot qualifies to enter the contest). The robot does not hhold the cup in this test but additional marks will be given for qualifying when the robot is holdicup.

1.7.h. The Robot can extend to any size or shape it desires, as long as it is within the room wexpected candle.

1.8 EXTINGUISHING THE FIRE

The fire is considered extinguished, when the LED candles are completely covered by the cup rflush on the playing surface.

1.9 LIGHTING

The lighting condition of the arena will not be specific or fixed.

2.0 CABLES



There can be no cables dragging behind the Robot as it moves. It is recommended that the Robot own microprocessor and power supply, as the Robot will not be allowed to move with connectingcables or computer attachments.

2.1 TIME LIMIT

2.1.b.The maximum time given for the Robot to locate and extinguish the fire is three (3) minute

2.1.c.If the Robot locates, extinguishes the candle, and returns to the Home Area before the thrminutes elapse (without committing an offense), then an additional point will be awarded, i.e., onfor returning to the Home Area.

2.1.d.If a Robot does not move or perform any function for a period exceeding one (1) minute, it lose that trial.

2.1.e. At the end of the three (3) minute period the Robot should stop moving.

2.2 SCORING

A maximum of 100 points can be obtained for each trial once no offense is committed. Poinallocated as follows:

2.2.a. Ten (10) points will be awarded if the Robot moves completely out of the Home Area iparts of the robot should cross the borderlines of the Home Area.

2.2.b. Seventy (70) points will be awarded for extinguishing the candle.

2.2.c. Twenty (20) point will be awarded for returning to the Home Area after the caextinguished. If however the robot enters a room on its return these points will be lost.

2.2.d. A bonus of the time remaining in seconds divided by 10 will be given to teams successfully extinguishing the fire and returning to the Home Area.

2.2.e. If a Robot allows 60 seconds to pass without moving or performing a function, the trial stopped but, all points obtained for that try will be awarded.

2.2.f. A Robot being measured for the competition gains 10 points for qualifying while holding the

2.2.g. A robot loses 20 points for each deployment of the cup when it is wrong.

2.2.h. A Robot touching the wall in their run will lose 5 points.

2.3 WINNER

The final score is the sum of each of the three trials for each Robot. The Robot with the highest fina

All walls must be 2 cm thick and 23 cm high, and the base is made of 1-inch thick plyboard.

will determine the winner. In the unlikely event of a tie, a playoff will determine the champion.
