| There will be no
age limit on the Robot Soccer Competition. The
Soccer Robots should use RCX and at least 50% LEGO
products, which can be from any set. There are no
limitations on sensors and programming language.
Participants should bring their robots
ready-to-go, and not assemble during the
competition. Robot Soccer should be played with 2
robots on each team. |

The playing field is 48 inches (122 cm) by
72 inches (183 cm).
 |
|
|
FLOOR |
| |
The floor of the playing field will be
covered with a printed gray scale that will be
available from Glasgow Science Pte Ltd. .The playing field may be placed
on a table or on the floor. Every effort shall
be made to ensure that the field is flat and
level. However, it is recommended that teams
design their robots to have a ground clearance
of at least 1cm in order to cope with slight
curvatures of the surface. |
| |
|

The width of each goal is 18 inches (45 cm).
The back of the goals will be painted black. The
interior wall of the goals will be painted grey,
consisting of 75% White and 25% Black |
| |
 |
| |
|
|
|
LIGHTING |
| |
Teams must come prepared to calibrate their
robots based on the lighting conditions at the
venue. Every effort will be made to keep ambient
light to a low level with infra red sources from
incandescent lights and natural lighting
removed. The committee will release the range of
light readings to be expected, at least one
month prior to the
event. | |
ROBOTS
|
|
DIAMETER |
| |
The standing robot must fit inside an
upright 22cm diameter cylinder. Robots will be
measured with all parts fully
extended. |
| |
|
|
|
HEIGHT |
| |
The robot height must be 22cm or
less. |
| |
|
|
|
MARKING/COLORING |
| |
Competitors are encouraged to decorate their
robots to give them individuality, however
colors of robots should not interfere with light
sensors readings of other
robots. | |
Team Structure
| |
A team shall consist of no more than 2
robots and 4 humans. Each team must nominate a
captain who will control the robots through the
game. | |
Ball
Wiltronics RoboBall Mk 2
- (Glasgow Science Pte Ltd is the sole
agent in Singapore). Wiltronics RoboBall Mk
2 is chosen for RoboCup Junior International.
The Wiltronics RoboBall has been selected, to be
used as the official RoboCup Junior
International ball.
The ball
will transmit infra-red (IR) light. The ball
will be close to 7.5 cm in diameter. |
 | |
Infra Ray Detector
(Glasgow Science Pte Ltd is the sole agent in
Singapore)
Advanced RoboBall Sensor Detector
designed to detect the InfraRed light emitted by
a RoboBall. The sensor has an adjustable range
and adjustable sensitivity. It can be adjusted
to minimise back ground light whilst maintaining
a high sensitivity to the output from the
RoboBall
|
 | Inspection
|
|
SIZE
INSPECTION |
| |
The robots will be examined by a panel of
referees before the start of the tournament to
ensure that they meet the constraints described
above. While being inspected, each robot must be
at its maximum size; i.e., anything that
protrudes from the robot must be fully extended.
Any violations of the constraints may disqualify
a robot from the tournament. |
| |
|
|
|
Authenticity of Students
Work |
| |
Team members will be asked to explain the
operation of their robots in order to verify
that the construction and the programming of the
robot is their own work. Robots must be
predominantly constructed by the students.
Commercial kits may be used but must be
substantially modified by the students. Teams
will be disqualified at the discretion of the
tournament referee if robots are not essentially
the work of the students. |
| |
|
|
|
Mentor
Exclusion |
| |
Mentors will not be allowed in the
inspection area or take part in any discussions
while inspection is taking
place. | |
| Game Play |
|
|
Pre-game
setup |
| |
Organizers will make every effort to provide
the teams access to the competition area at
least two hours before the start of the
competition. They will also strive to allow at
least 10 minutes of setup time before each game.
Participants should be aware, however, that
conditions may arise where this much time cannot
be provided. |
| |
|
|
|
Length of
Game |
| |
The game will consist of two 10-minute
halves, with a 5-minute break in the middle. The
game clock will run for the duration of the game
(two 10-minutes halves), without stopping
(exception noted in "Damaged Robots"). The
referee will be in charge of the game clock.The
clock will be stopped for halts of play and
positioning of robots during finals
play. |
| |
|
|
|
Selection of Kick Off
and Ends |
| |
Selection of ends of kick off will be done
by the toss of a coin. The referee will toss the
coin and the first mentioned team in the draw
shall call. The winner of the toss can choose
either which end to kick to or to kick off
first. Having made that decision, the loser of
the coin toss will choose the other option.The
team not kicking off first, shall kick off to
begin the second half. |
| |
|
|
|
Kick-Offs |
| |
- Each half of the game begins with a
kick-off. At the time of a kick-off, all robots
must be in located on their own side of the
field. All robots must be halted. The ball is
positioned by the referee in the center of the
field, and all robots on the team not kicking
off must be at least 6in (15cm) away from the
ball. The team not kicking off, places their
robots first and the team kicking off may place
one robot near the ball. The referee may adjust
the placement of the robots to their
satisfaction.
- On the referee's whistle, the
robot kicking off will be started by remote
control or by a human team member. The robot
will then strike the ball. This same robot
cannot re-contact the ball until 1 second has
elapsed. After the robot has contacted the ball
all robots must be started immediately. When 5
seconds has passed, the referee will blow the
whistle again and if any robots have not been
started, a free kick will be given to the
opposing team. If the robot taking the kick off
has not struck the ball after 5 seconds, other
robots can be then be started |
| |
|
|
|
Humans |
| |
In general, movement of robots by humans is
not acceptable. There are three exceptions to
this rule: see "Kick-Offs", "Stuck Robots" and
"Damaged Robots". Before the start of each
match, teams should designate one human who will
be allowed to start, place, remove and replace
robots during the game, based on the stated
rules.
Team members within the vicinity of
the playing field are to remain seated while the
ball is in play, unless otherwise directed by
the referee. |
| |
|
|
|
Ball Movement and
Control |
| |
- The ball must go forward from the
kick-off, or else the kick-off will be repeated.
If a kick-off needs to be repeated more than
three times, the kick-off right is passed to the
other team.
- A player cannot "hold" a ball.
Holding a ball means taking a full control of
the ball by removing all of its degrees of
freedom. For example, this would mean fixing a
ball to the robot's body or surrounding a ball
using the robot's body to prevent access by
others.
- The ball must be visible at all
times. It cannot be underneath a robot! No
encircling clamp or entrapment of the ball is
allowed. Other players must be able to access
it. The gap in arms in front of the player must
not exceed 1.5 times the diameter of the ball.
Arms must not protrude any further than 50% of
the diameter of the ball.
- The ball may be
lifted during play by the robots. However, the
height of the ball from the table must not
endanger spectators, the referees or human team
members!! |
| |
|
|
|
Scoring |
| |
- The ball must be free rolling to score a
goal. The only exception to this is when a robot
makes first contact with the ball less than 15
cm in front of the goal.
- Once the ball has
gone into the goal area and goal has been called
by the umpire, the ball will be placed manually
back in the center of the playing field. If the
ball crosses the goal line 5.5in (14cm) above
the table, the goal is disallowed and a free
kick is awarded to the defending team.
-
After a goal is scored, a kick-off will occur.
The non-scoring team will be awarded the ball.
See "Kick-Offs". |
| |
|
|
|
Goalie |
| |
If desired, teams may designate one player
as a goalie. Note that the goalie is subject to
the same foul rules as the other robots on the
field. See "Fouls". |
| |
|
|
|
Fouls |
| |
The following fouls are defined:
| |
Lack of progress. |
| |
If it is deemed by the referee that game
play has stopped, then a free kick is awarded to
whichever team effectively moved the ball last.
A game is considered stopped if the ball has not
been touched by any robot for 20 seconds or it
appears that no robots are likely to hit the
ball. Lack of progress is also considered when
the ball is entrapped by two or more robots, but
not involving the wall of the field. If the ball
is stuck against the wall :see 6.11 Ball
entrapped on the wall |
| |
|
| |
Non-moving
robots. |
| |
If the referee determines that a robot is
not moving for a period of 20 seconds or longer,
the referee may remove it from the playing field
or at the request of a team member. Participants
may repair the robot and ask that it be put back
in play after at least one minute. |
| |
|
| |
Multiple Defense.
|
| |
When more than one robot from the defending
side enters the defense zone and substantially
affects the game, a foul will be called and a
free kick will be
declared. | |
| |
|
|
|
Free
Kick |
| |
Free kicks are taken after a foul or a
stoppage in play. If the free kick is taken
after a foul, the ball is placed at the point
where the foul was committed. If the free kick
is taken after a stoppage in play, the ball
remains in place. If the ball is within 6in
(15cm) of a wall or the goal line, the ball will
be placed 6in (15cm) from the wall or goal line.
All defending robots must be placed at least 6in
(15cm) from the ball. The team receiving the
free kick may place one robot near the ball.
Other robots further than 15cm away cannot
change their position on the field, but may be
rotated while remaining in that position.The
robot will then strike the ball. This same robot
cannot re-contact the ball until 1 second has
elapsed. After the robot has contacted the ball
all robots must be started immediately. When 5
seconds has passed, the referee will blow the
whistle again and if any robots have not been
started, a free kick will be given to the
opposing team. If the robot taking the kick off
has not struck the ball after 5 seconds, other
robots can be then be started. |
| |
|
|
|
Ball Entrapped at the
Wall |
| |
If a robot or robots have the ball trapped
against the wall and the referee deems that
there is no chance of it being freed. He can
remove the ball to the nearest available point
45cm out from the nearest goal post. The referee
will also free any robots, with minimal
movement, which are still stuck. |
| |
|
|
|
Offside |
| |
There are no offside rules. |
| |
|
|
|
Timeouts |
| |
There are no timeouts in the game. |
| |
|
|
|
Substitution |
| |
Substitution of robots is strictly
forbidden. Each team is allowed two and only two
robots, both of which must pass inspection prior
to the commencement of the tournament. Any team
found violating this rule will be disqualified.
|
| |
|
|
|
Stuck
Robots |
| |
Humans are not allowed to free robots that
are stuck, except at the referee's discretion.
In this case, the referee may initiate a
stoppage of play, and then one human team member
may move the stuck robot(s) only far enough to
free them. The referee may re-position the
robot(s) as well. |
| |
|
|
|
Damaged
robots |
| |
If robots fall apart during game play, with
the referee's permission, one team member may
remove the damaged robot from the field. The
team may fix the damaged robot on the spot and
return it after at least one minute, to a
position on the field determined by the referee.
Play continues during removal, repair and
replacement. Playing Field |
| |
|
|
|
Modification |
| |
Modification or damage to the playing field
and/or the game ball is forbidden. Should this
occur, the game is suspended, and the
appropriate restoration is done immediately,
before the game resumes. If the referee deems
that one team caused the damage purposely or
maliciously, then that team may be disqualified.
|
| |
|
|
|
Charging/Attacking |
| |
During play, if a robot utilizes a device or
an action which continuously exerts, or whose
primary purpose appears to be, serious damage to
other robots' functions, the referee can present
a yellow card as a warning to the responsible
robot. A team member must then remove the robot
from the playing field and correct the problem;
play will continue (as in "Damaged Robots").
Once the correction is made, the robot may
resume play under an approval by the umpire. In
case the problem is repeated, the umpire
presents a red card and the offending robot will
be permanently removed from the game. This rule
could be invoked on a robot should it
continuously charge a robot not in possession of
the ball. |
| |
|
|
|
Sabotage |
| |
There is no sabotage allowed. Robot that
cause deliberate interference with other robots
will be disqualified. Robots that perform
serious and repeated charging and/or attacking
of other robots, effecting damage to another
robot's functions, is not allowed. |
| |
|
|
|
Fair
play |
| |
Aside from the above items, no regulations
are placed against possible body contacts,
charging, dangerous plays, obstructions, etc.
However, it is expected that the aim of all
teams is to play a fair and clean game of robot
soccer. | |

Rule
Clarification |
| |
Resolution of dispute and interpretation of
ambiguity of rules shall be made by three
officials, who will act as the tournament
committee, designated prior to the tournament.
The umpires shall not have any relationship with
any of the teams entered in the tournament.
Ambiguities shall be resolved by referring to
the RoboCup Junior Australia regulations.

modifications to the rules to allow for special
problems and/or capabilities of a team's robots.
This is provided that there are no major
objections from a majority of the
contestants. | |
Environment
|
|
Sharing |
| |
An understanding that has been a part of
World Robocup Competitions, is that any
technological advantage must be shared with
other competitors after the event. This allows
the competition to develop and encourages
further development. Any student developments
must be published on request on the RoboCup
Junior web site after the event. |
| |
|
|
|
Wireless
Communication |
| |
No wireless or infra-red (IR) communication
devices will be allowed in the tournament hall.
|
| |
|
|
|
Spirit |
| |
It is hoped that all participants, students
and mentors, will respect the RoboCup Junior
mission. The referees will officiate within the
spirit of the event. "It is not whether you win
or lose, but how much you learn that counts."
|
| |
|
|
|
Consideration for other
teams |
| |
Competitors are not to enter setup areas of
other leagues or other teams, unless invited to
do so by team members. |
| |
|
|
|
Behavior |
| |
All movement and behavior is to be of a
subdued nature within the tournament venue.
Participants who misbehave may be asked to leave
the building and risk being disqualified from
the tournament, at the discretion of the
referees, umpires and conference
organizers. | | |
