Rules for Micromouse Halfsize

Micromouse Contest is a contest which an autonomous robot runs through a designated
maze to compete for intelligence and speed. A robot participating in this contest is termed 
Micromouse.


1. Rules for Micromouse Halfsize
1-1. Micromouse must be autonomous. It is not allowed to use an energy source given by combustion process.
1-2. Micromouse must not have any hardware or software added, deleted, replaced or
modified by the operator during the contest. It is however permitted to make minor repairs.
1-3. Micromouse is not allowed to leave any of the parts on the maze.
1-4. Micromouse is not allowed to jump over, climb, scratch, damage or destroy the walls.
1-5. The projection of the Micromouse on the floor must be contained within a square of
each sides in 12.5 cm. This must be satisfied even when the shape of the Micromouse
changes during the contest. There are no restrictions to the height of the Micromouse.

2. Rules for the Maze.
2-1. The side of the walls are white, and the top of the walls are red. The floor of the maze is painted in black.
It is made of wood finished with non-gloss black paint.

However, the exterior walls of the starting point (outside the maze) and the interior walls of
the finish zone are painted in red.

The top of the walls in the starting unit and finish zone is painted white.
2-2. The maze are composed of 9 x 9 cm unit squares. The maximum number of squares
will be 32 x 32 squares. The height of the walls is 2.5 cm and its thickness is 0.6 cm (see Fig.
1 for details).
2-3. The starting point of the maze will be located at one of the four corners of the maze.

Micromouse starts in a clockwise direction. The finish point and the size of the finish zone
will be determined individually for each competition. The entry point to the finish zone will be
indicated by a set of x-y coordinates. (See Fig. 2 for an explanation on how to read
coordinates.)

2-4. There are Small square zones, each 0.6 cm x 0.6 cm, at the four corners of each unit
square. This zone is called lattice points, and a maze are built so that there are at least one
wall to a lattice point except for the interior of the finish zone (see Fig. 1 for details). The
entire maze will be completely surrounded by exterior walls (see Figs. 1 and 2).


3. Rules for the contest.
3-1. The fastest lap from the start to the finish zone[A1] will be recorded as its official time.
Micromouse Contest will be evaluated on the fastest lap and its independence. The criteria
for evaluation and the rules for awarding prizes are determined at each contest.[A2]

3-2. After the maze is open to public, the operator is not allowed to feed any maze
information to Micromouse. During the contest, the operator is not allowed to change any
maze information gathered by the search run, using switch or its kind.

3-3. Micromouse begins its run from a starting point and ends when it came back.The run
will also finish when Micromouse stops for 2 seconds or it is approved by chairperson.

3-4. When Micromouse returns to the starting point and beings another run automatically,
Micromouse must stop for at least two seconds at the starting point.

3-5. The operator is not allowed to touch the Micromouse during the run unless instructed
or given permission by a tournament chairperson[A3] to do so. The tournament
chairperson accepts an operator's request to discontinue its run if an apparent malfunction
is found in his/her Micromouse's run. For the cases in which a request to discontinue is
made for any other reasons, permissions will be made on the condition which all memory of
the maze is erased.

3-6. The time limit for Micromouse will be determined individually for each competition within 15 minutes.
Micromouse is permitted to make up to 5 runs in the specified timeframe.

3-7. The lap have considered to have completed when the entire lower portion of its body ,
defined as its portion up to 2.5 cm above the floor level has entered the finish zone.

However, elapsed time is measured from the moment the sensors placed at the starting
point senses the Micromouse and to the moment the sensor located at the entry point to the finish zone
senses the same Micromouse.

3-8. The lightings, temperature and humidity of the room in which the maze is located will be
those of an ambient environment. Requests to adjust the lightings will not be accepted.

3-9. The tournament chairperson has the rights to ask to the operator about the
Micromouse if it is appropriate. The tournament chairperson also has the rights to stop a run, declare disqualification,
or ask for instructions if it is appropriate.

3-10. Prizes and evaluation criteria will be set individually for each competition.

[Attention]
1. The contestant is not permitted to load programs or replace ROM during a contest.

It is also prohibited to send any information to Micromouse from development unit or
console box that is independent from the main Micromouse unit.
2. The contestant is permitted to remove dust and debris on the tires during a contest using adhesive tape, etc.;
however, no solvents and likely may be used for the purpose of increasing friction.

3. In each of its runs, Micromouse may continue its search even after it has reached the destination.
In such a case, the elapsed time when Micromouse has reached the finish zone for the first time will be recorded.

4. If Micromouse returns to the starting point and begins another run within two seconds, it is assumed
that the next run has begun. However, this run will be invalid.

5. Except for the run, Micromouse may not be placed for adjustment or other purposes in
any part of the maze other than on the starting point.

6. Dimensions of Micromouse

The size of the lower structure of Micromouse is constrained by the size of the maze despite the provisions of Article 1-5.

7. Structure of Maze
The maze is made in a sensible accuracy. So that there will be errors to the maze dimension to some extent.
As the maze is designed to come apart for preservation, it may produce
gaps or difference in level of approximately 1 mm between sections of the walls or the floor.
There may be non-uniform coloring, discoloring and stains.

8. Type and position of the Sensors for recording

Type: Transmission infrared sensors.
Optical axis placed 0.5 cm above the floor. (See Fig.1)
Position: Start sensor: At the boundary between the starting unit square and the next unit square.
Goal Sensor: The entry point for the finish zone.
9. A goal marker may be placed at some point in the finish zone.
It may also be removed subject to the approval of the tournament chairperson.
