1) Objectives
Carrier machine is designed to approach robotics young students to learn robotic with fun. This category will attract younger students with its possibilities that expand their ideas in many ways. This new category will bring popularization of robotics to the public as well as potential participants of IRO.

2) Participants
Junior and Challenge League

3) Team Formation
2~3 persons and 2 robot per team

4) Game Method
A playground assigned by the committee will be used for Carrier Machine. Two robots must co work in order to complete mission to move object from departure to destination. All robots must trace line under 3cm and the team that carries more objects within duration of 3 minutes will be the winner.

5) Game Rules
* Robot should be constructed in 3 hours.
*The participants should use a controlling part of robot after setting up in advance; on the contrary, other parts except the controlling part should be constructed on a field spot.
*The size of the robots must be smaller than 30cmX30cmX30cm even when they are switched off and fully extended. If the robots are bigger than the size that is mentioned in the rule, the team will be disqualified.
*The robots must be built on the site of the competition by the participants. Using unauthorized parts by the committee is prohibited.
* Robot should work autonomously with an independent electric power supply; it cannot use a combustible device. Direct control by the participants is not allowed except the starting of the robot.
*Participants should not touch the robot during the competition without permission from the referee.
*The robots must complete the mission within 3 minutes.
* Participants should not add, remove or change any hardware or software of the robot during the competition.
*The team that moved more the mission object with accuracy will be the winner. The robot that picks up the object (robot A) must not leave assigned area. The robot that received the object from robot A (robot B) delivers the object to the destination without crossing the line for pick up robot. If the robots moved all the objects from departure the participant can move the object to departure to continue the game.
*The rules that are not sited in the official rules on IROC website can be discussed in the judge meeting on the game day. And once the rules been notified to the participants no one can object the rules.
*The robots prohibited to use RF/IR controller.
*A computer is allowed for programming; participants should prepare for the computer.
*If the robot stands on the same position and does not move for more than 10 seconds during the mission, the team will be disqualified.
*The robots may leave the course (the black trace) however the robot must start at the leaving point when it starts again.
*If the robot drops the object, it doesn’t count as a point.

6) Playground
* A playground assigned by the committee is in color of white with a black line 3cm wide painted on it. The black line is composed of straight lines, circular lines. The object stand is rectangle pillar with size 10cmX10cmX9cm. The size of the object is 3cmX3cmX6cm. The destination is 17.5cmX12.5cmX2cm rectangle with a groove.

* Robot A picks and delivers the object to robot B at the meeting point. Robot B must deliver the object to the destination and continue.
* Nor robot A or robot B should complete the mission by it selves. Each robot must work in separate.
* Robots may touch any part of the object but if robot drops the object it will not be count as a point. The team can continue on the mission in the remaining game duration.

7) Method of Scoring
* The team that scores the more points within 3minutes will be the winner.
* The team that touches robots without the referee’s permission during the games will be disqualified.

8) Tie breakers
* The team that used lower voltage will be the winner.
* The team with lighter robots (add 2robots’ weight) including batteries will be the winner.
* The team with outstanding construction skills.
