IRC 2020 General Information and Rules

  • International Robot Challenge (IRC) is an annual robotics competition for adolescents age between 12-18. IRC promotes the role of engineering, coding, and robotics in education. It aims to improve participants’ creativity and enthusiasm by letting them solve the problem of the Mission Game by asking them to design, build and program their unique robots. IRC nurtures students’ creativity and interest in robotics. IRC is a lifetime chance for students to develop their 21st-century skills like being a team member, social, researching and problem-solving. 

IRC is held in ” the land of smiles”. As IRC family, diversity of involving countries, peace, and respecting each other have great importance for us. 

We believe that this dialogue will help us to make the world a better place by communicating the environmental and technological problems.

    Each team can have three students maximum.  A school can apply with more than one project. However, an individual cannot join more than one team. Each team can prepare only one robot for the Mission Game.

    The first IRC in 2019 used only LEGO,  and IRC 2020 is designed for LEGO-like Mindstorms, Lego Boost, Lego NXT, or other Lego parts and motors (Lego Power functions) and MRT Series, MRT-X & HUNA educational robot kits. (

    Important Update:

    Many schools are asking to use different robotic kits for IRC 2020. So we decided to allow robotic kits other than Lego and MRT Series, MRT-X & HUNA educational robot kits. Robotic teams can use Arduino, Makeblock and any other robotic kits since the teams are going to build their own best robot and complete the task, this will not affect the team’s evaluation and every robotic team will be judged by the assigned referee. There will be no comparison between the teams in terms of their robotic kits. During the mission game, referees will only focus on how the teams complete the mission game task either autonomous or remote-controlled.



    • Motivating students into engineering and science

    • Leading participants to next intellectual level

    • Engaging 21st learning skills

    • Cultivating analytical thinking among the secondary students

     2.Mission Game Rules and Details

    Climate and Pollution Mission

    Climate change is the biggest issue for today’s and especially for the future life on Earth. As we are experiencing significant impacts of climate change such as rising global temperature , rising sea level and extreme weather events. The greenhouse gas emissions from human activities are driving climate change and continue to rise. CO2 is the greenhouse gas most commonly produced by human activities and it is responsible for 64% of man-made global warming. Amount of CO2 now is threatening our oceans and organisms. Without action our world would no longer suitable to live for living organisms and species will be extinct gradually. We harmed our Earth planet, our green home and your mission is now to protect our Earth to keep in current climate condition.

    In the IRC Mission Robot Game field, there are two development divisions. The first one is the “Seed Development Division” -this division is working on developing natural seeds, protecting all the plant species in the world and supplies free seeds and seedlings for tree planting campaigns. The second division is the “Environment and Sustainable Development Division” -this division is working on transforming harmful pollutions to helpful way, and developing AI (artificial intelligence) technologies to protect environment from wildfire both naturally or man-made fire, water pollutions, air pollutions and land pollutions. In the mission game you can find four types of objects to finish your task; seeds (blue seeds and green seeds in the Seed Development Division.), smart containers (yellow container and red container in the Environment and Sustainable Development Division.) You need to carry all of these to their destination.

    Mission Game

    The IRC mission game has 3 rounds and each round is 4 minutes: autonomous or driven by the remote controller. ‘The robots compete in a field which will be divided into two identical subfields. The subfields will be separated by blue and green lines which is called “Woodland River”. With this separation the teams will have their private region to complete the tasks. At each subfield, all zones are marked with color and written name (printed on matte and smooth surface) Please check the IRC 2020 Robot Mission Game field design for more details.

    Blue seed is Lodgepole Pine seed and green seed is Coast Redwood seed.

    Yellow container is ocean water treatment agent (micromotors) and red container is self-extinguisher container.

    There will be 8 blue cubes, 8 green cubes for the seeds, and 8 yellow cylinder, 4 red cylinder in each division. Cubes and cylinders will be placed in the game field marked area.

    The Robot is responsible to pick up the seeds and the containers from each division and transporting them to 3 different colored areas which are representing tree planting area, ocean treatment area and wildfire area. Cubes and cylinders must be placed correct color area, and must be placed in the black circle or black square in its place.

    Your robot is not allowed to pass the border (“Woodland River”) of IRC mission game subfield. The robot will start its task from the robot lot and return to robot lot after finish its task or any emergency issues. Teams are allowed to make design modifications on the robot like adding or removing attachments or changing the code during the competition round ONLY within the robot lot.

    Scoring of the Mission Task

    Each mission game material placed in a correct section gives you 30 points. If a robot does this task in an autonomous way gets an extra 15 points. Placing a game material in a wrong section gives you only 15 points. If a game material touches in the section black circle gives you only 20 points. (If this is done by autonomous mode, will be added 15 points.)

    You may either drag the items on the game field or lift them to transport their section.

    There are some areas moving your robot is dangerous and if you drive your robot accidentally or autonomous mode robot is uncontrolled touch those areas the team will lose 50 points.

    One of the dangerous area is the former nuclear research illegal waste facility, the area is known and protected, and it is radiation zone. Any robot parts are inside the caution tape line will be penalty.

    The other dangerous area is near Woodland Active Volcano area. Woodland Volcano is active volcano and it might harm its near area with the rapid eruption. You must be careful while you driving your robot or well coding to not move near Woodland Volcano.

    There will be three rounds for each team and the team may compete in any side of the field; different rounds may be held in different fields.

     If teams violate any fair play rules, like destroying or blocking the opponent team’s robot intentionally, or moving the other side of “Woodland River”, the team will lose 100 points. In addition to these penalties, teams violating fair play rules can be subject to disqualification from the competition by the referee’s decision.

    If your robot cannot hold or accidently move some of the game materials to Woodland Volcano, Radiation Zone and on or the other side of the Woodland River, it means that the team lost that or those game material/s.

    Robot Design and Inspection

    All finalist robots will be inspected on the setup/practice day and any robot which does not apply the below rules would be disqualified and ineligible to compete in IRC. But the team will be given notice to modify or resize their robot IRC size requirement.

    Size: Robot must fit in the 15-inch cube. Width: 15 inches Height: 15 inches Length: 15 inches.

    Since we only allow Lego Robot materials to build up and design your robot for the IRC mission game, you are allowed to use unlimited materials of any Lego Robot Set; intelligent brick or other lego micro controller, motors, sensors, etc… However, each team is allowed to use maximum two remote controllers; lego IR Beacon, or mobile phone/tablet application.
