1. CONTEST OBJECTIVE

To build a microcontroller controlled Robot that can move through a model floor plan structure of ahouse, find a lit candle and then extinguish it in the shortest time. This is meant to simulate the real-worldoperation of a Robot performing a fire security function in a actual home. The candle represents a firewhich has started in the home and which the Robot must find and extinguish.

2. THE HOUSE FLOOR PLAN STRUCTURES AND FEATURES

The official floor plan structure contest area is shown in Attachment A. This is what the contest structurewill look like. This is not a maze contest where the Robot has to figure out how to move through thestructure. The design of the structure will be known before hand (see Attachment A) and the goal is tofind and extinguish the candle as quickly as possible. However, just like in the real world where there isalways a measure of uncertainty in any information, the dimensions in the Attachment A floor plan areapproximations. The actual dimensions may vary up to as much as an inch from the given values.Welcome to operating Robots in the Real World!

The walls of the structure will be 13 inches high. The walls will be painted with flat white paint. The floor

of the arena will be a smooth, wood surface painted with flat black latex paint. Any seams in the floor will be taped over and painted with the same flat black paint.

As noted in the Attachment A floor plan, all hallways and doorways to room will be 18 inches wide.There will not be a door in the doorways, just an 18inch opening. There will be a white 1" wide line madewith white tape or painted on the floor across each doorway to create the entrance to each room.

The floor of the arena will be black but there is no guarantee that the floor will stay uniformly black throughout the entire contest. The floor may also have small (1/8" diameter) red or blue dots on it toindicate the potential locations of candles.

The Robot will start at the Home Circle location marked by the H in a circle on the arena floor plan (seeAttachment A). The actual Home Circle will be a solid white circle without the H painted on the floor.The 12" diameter white Home Circle will be in the center of the 18" hallway, so there will be 3" of space

between the edge of the Home Circle and the walls. Therefore the center of the Home Circle will be 9"from the either side wall. Notice that on the arena floor plan in Attachment A there is no gap in the outer wall of the arena behind the Home Circle. This part of the wall can be removed to allow contestants easier access to their Robots in setting them up, but the wall can be replaced in this section if it helps the Robot'soperation. Robots may also use any placement fixtures if they help the Robot initially align itself in theHome Circle. The Robot must start within the Home Circle, but once started, it can go in any directiondesired and can go either horizontally or vertically in the diagram shown in Attachment A.

Some of the corners of the arena may have black, plastic connecting hardware which sticks out about 1/2inch from the walls. These may be used to hold the arena structure together.

3. AMBIENT LIGHTING

The ambient light level in the contest area is impossible to determine until the actual day of the contest.

Contestants will be given time on the contest day to make ambient light level readings if necessary tocalibrate their Robot. The room will be lit by overhead high pressure sodium vapor lights.

4. ROBOT OPERATION

Once turned on, the Robot must be self-controlled without any human intervention, that is, these are to becomputer controlled and not manually controlled devices.

The Robot can bump into or touch the walls of the arena as it travels, but it can not mark or damage thewalls in doing so. However there will be a penalty for touching a wall. The Robot can not leave anything behind as it travels through the arena. It can not make any marks on the floor of the arena that aid innavigation as it travels. Any Robot that deliberately, in the judges' opinion, damages the contest arena(including the walls) will be disqualified. This does not include any accidental marks or scratches made inmoving around.

The Robot must, in the opinion of the official judges, have found the candle before it attempts to put itout. The Robot cannot just blow out the candle by accident.

5. PUTTING OUT THE CANDLE

The Robot must not use any destructive or dangerous methods to put out the candle. It cannot use suchitems as water, CO2, Halon, etc., any method or material that is dangerous or will damage the arena is prohibited. For example, the Robot can not explode a firecracker and put the candle out with theconcussion. The Robot can not knock the candle over to put it out. The robot must distinguish the firusing and air (blower)

The candle can not be knocked over while it is still lit. If a Robot accidentally knocks over a candle after it has been put out, then the Robot's trial run will still count, but there will be a penalty. The candle will be mounted on a wooden base so that it will not be easily knocked over.

6. ROBOT SIZE

The maximum size of the Robot shall be 12.25" by 12.25" by 12.25" or A4 paper size. The Robot can notlook over the walls of the structure and must never extend itself beyond 12.25 inches in any dimension.All Robots will be carefully measured. Don't let your Robot be disqualified because it is slightly over thelimit.

If the Robot has feelers to sense an object or wall, the feelers must be counted as part of the Robot'sdimensions and can not extend beyond 12.25" from side to side.

If contestants want to add a flag, hat or other purely decorative, non-functional items to the Robot, they

may do so as long as the item has absolutely no effect on the operation of the Robot.7. ROBOT WEIGHT

There are no restrictions on the weight of the Robot.

8. ROBOT CONSTRUCTION MATERIALS

There are no restrictions on the types of materials used in the construction of the Robot.

9. THE CANDLE

The lit candle is supposed to represent a small house fire that the Robot is attempting to find and put out.The bottom of the candle flame will be between6 and 8 inches off the floor. This height includes theheight of the wooden candle support base. The bottom of the candle flame will start out at 8 inches abovethe floor and when in the course of the contest's many trials, it burns down to 6 inches above the floor, it

will be replaced by a new candle. The candle used will be a standard approximately 1 inch thick whitecandle. The flame will be visible from the side and not hidden by unmelted wax as with thick candles.The exact height and size of the flame is unknown and variable and will be determined by the specificconditions of candle and its surroundings. As along as the candle is within the specifications outlinedabove, 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 room in the arena. The candle has an equal chance of being in any of the 4 rooms in each of the 3 trials that a Robot has. Hopefully the candle will be placed indifferent rooms in each trial to best test the Robot's operation, but it might be possible for the candle to bein the same room twice. If it happens that the candle is placed in the same room for both the 1st and 2ndtrials, then we will make sure that it is not in that room for the 3rd and last trial. Thus every Robot willhave the candle in at least 2 rooms & maybe 3, during its 3 trials.

The candle will not be placed in a hallway, but it might be placed just inside a doorway of a room.However the front of the Robot will be able to move at least 6" into the room before it encounters thecandle.

10. SENSORS

There is no restriction on the type of sensors that can be used as long as they do not violate any of theother rules or regulations.

Contestants are not allowed to place any markers, beacons or reflectors on the walls or floors to aid in theRobot's navigation.

Robot builders should be aware that many modern film and video cameras transmit infrared light as partof their automatic focusing systems. Ambient lighting in the contest room may also be a source of IR,



visible and UV light. If a Robot uses light sensors to find the candle or detect walls, the builders shouldtake steps to prevent these light sources from interfering with its operation.

11. THE ORDER OF RUNNING

The Robots will be assigned numbers to determine the order in which they will compete in the contest.Each Robot will make a run in the arena in the order in which it is assigned. After every Robot has madeits first run, then the whole process will begin again for the second run. In other words, the Robots willcompete consecutively and when everyone is done with their first attempt, then the whole process willrepeat for the second and finally third attempts.

Contestants will have time between their runs to make any adjustments, modifications or repairs to their Robot, but once the Robot before them has completed its run, then they will have 1 minute to get their Robot in the arena and started on its run. Any Robot that is not ready to run after 1minute will forfeit it'schance at that trial. It may still compete in any other runs that are left. Once assigned, the order of runningwill not be changed. If you are not ready, then you've missed your turn. The time between turns isundetermined and is controlled by how long the other competitors take to complete their runs.

However, if a contestant wants to run their Robot successively without any delay between runs, they maydo so. We actually encourage this since it helps to speed up the contest.

Once the Robot is ready, the location of the candle and any furniture, if necessary, shall be determinedand the candle and the furniture shall be put in the proper locations.

The contestants will show a judge how to actuate the Robot and then the judge will actually presswhatever buttons necessary to start the Robot.

12. TIME LIMITS

In order to achieve the contest objective of building a Robot that can find and extinguish a fire in a house,finding the fire within a reasonable period of time is very important. The maximum time limit for a Robotto find the candle will be 5 minutes. After 5 minutes the trial will be stopped. The maximum time for theRobot to return to the Home circle in the Return Trip mode will be 3 minutes. If in any trail, a Robot getsstuck in a loop and performs the same movement 5 times in a row, that trial will be stopped. Anytime theRobot does not move at all for 1 minute, the trial will be stopped. Any trial that is stopped will count asno score for that Robot. Stopping a trial run for any of the above reasons will have no impact on any of the other two trial runs that the Robot has.

13. SCORINGThe Robot with the highest Final Score (FS) is the winner. The Final Score is calculated from a number of different factors.

14. PENALTIES

The goal of this contest is to be as real-world realistic as possible. Therefore there are two actions whilenot illegal, are not what would be a good operating method in the real world. Thus there are PenaltyPoints (PP)added to the Actual Time (AT) of any Robot which does them. You can still do these things, but you will get points minus to your Time Score if you do. Don't let these penalties scare you too much.These penalties are generally a small price to pay for a Robot actually manages to accomplish the task.

Touching a wall

Any Robot that touches a wall with any part of its body or feeler, either deliberately or accidentally will

have 5 points added to its Actual Time score for each time it touched a wall. Any Robot that slides alonga wall will have an additional 1 point added to its time score for each inch of wall it touched as it wassliding along. A Robot can still touch a wall to orient itself, but it will be penalized for doing so. (PP =5/hit and PP = 1/inch of sliding)There are no penalties counted for hitting the wall on the Return Trip back to the Home Circle after extinguishing the candle.

Touching the candle

Any Robot that touches the candle or its base with any part of its body or feeler, either deliberately or accidentally, will have 50 points minus to its Actual Time score. This is true whether the candle is lit or extinguished.

15. ROOM FACTOR



In order to make the contest realistic and to encourage the creation of smart Robots, we have deliberatelyadded uncertainty into the contest. The Robot does not know in which of 4 rooms the candle is in.Sometimes a Robot gets lucky and the candle is in the first room it searches and sometimes a Robot isunlucky and the candle is in the 4th room searched. The unfairness of this is that finding the candle in the4th room you look in is a lot harder and takes longer than finding it in the 1st room you search. To reducethe impact of "luck" and give some credit to the more sophisticated Robots that can search multiple roomssuccessfully, there will be a Room Factor involved in the scoring that will be multiplied by the TimeScore to get the Operating Score. The more rooms a Robot has to search before it finds the candle, thelower the Room Factor and thus the better the Operating Score.

If the candle is in the 1st room searched, the Room Factor will be 1.0If the candle is in the 2nd room searched, the Room Factor will be 0.9If the candle is in the 3rd room searched, the Room Factor will be 0.8If the candle is in the 4th room searched, the Room Factor will be 0.7

It does not matter in which order the Robot searches the rooms. The only thing that matters is how manyrooms the Robot has searched before it finds the candle.

Some Robots have extremely sensitive sensors and can tell if the candle is in the room by merely lookingin the doorway as it passes by. The Robot does not have to have entered a room to be considered ashaving searched it. Any Robot going past a doorway that it has not gone past before will be considered tohave searched that room. If the Robot has already searched a room and then goes past the doorway againon its way to a different room, that room will not be counted twice.

16. SAFETYThe contest judges may stop any Robot at any time if they feel that it is performing , or is about to perform, any action that is dangerous or hazardous to people or equipment. No Robot is allowed to useany flammable or combustible processes.

17. INTERPRETING THE RULES

In all matters of interpreting these rules before and during the contest and in any issues not covered bythese rules, the decisions of the official contest coordinator will be final.

18. UPDATED INFORMATION

All official registrants will be kept update as to any rule changes and/or modifications that should arise between now and the contest. We will also send the registrants more specific information about theschedule of activities on the actual weekend of the contest.
