Reference excerpt

The World Robot Olympiad (WRO) is a global robotics competition for young people. The World Robot Olympiad competition uses Lego Mindstorms manufactured by LEGO Education. First held in 2004 in Singapore, it now attracts more than 70,000 students from more than 95 countries. The competition consists of 4 different categories: RoboMission, RoboSports, Future Innovators, Future Engineers. and for the RoboMission and Future Innovators categories, it consists of three different age groups: Elementary, Junior High and Senior High. Participants below the age of 13 are considered as Elementary, participants from ages 11 until 15 years old are considered Junior High, and participants between 14 and 19 are considered Senior High.

History WRO was formally established in 2004, with the first international WRO final organized in 2004. Organizations from China, Japan, Singapore and Korea are considered the founding countries. In 2004, teams from China, Chinese Taipei, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Philippines, Russia, Singapore and Thailand took part in the first international final, held in Singapore. In 2004, the four founding countries established the international WRO Committee (now known as the WRO Advisory Council), which decided to establish a new and permanent robotics organisation, based on the idea that students from all over the world should have the opportunity to meet with other students to fulfil the new mission statement: "To bring together young people all over the world to develop their creativity, design & problem solving skills through challenging & educational robot competitions and activities" The WRO Committee decided on the new name World Robot Olympiad, and new WRO logos were developed. The WRO statutes and a set of general rules were worked out to ensure a sound and safe future for WRO. One of the major decisions, which appears in the Statutes, was that the international WRO event should be hosted by a new country each year and the WRO Committee should elect a chairman. In 2017, the host country of WRO was Costa Rica. This was the first time the competition was held outside the Asia Region and the first time it came to the Americas. In 2023, the world finals were hosted by Panama City. In 2024, the world finals were hosted by Izmir, Turkey. In 2025, the world finals were hosted again in Singapore

Categories At WRO, competitions are offered for students in the age from 8 – 19. WRO have four competition categories, with their own characteristics and challenges:

RoboMission RoboSports Future Innovators Future Engineers Each season the challenges and theme for the RoboMission and Future Innovators are developed with the country that hosts the International Final. The RoboSports rules and the Future Engineers Challenge game are designed together with experts in the robotic sciences community.

Overview of all WRO categories

RoboMission

Teams must create a robot which can complete a specified mission determined by the organiser and usually based on the Future Innovators theme. As of the 2022 season, robots are no longer required to be assembled at the competition venue. Instead, teams are allowed to build their robots before arriving to the competition venue. Each robot is restricted to be 25 × 25 × 25 cm (9.8 × 9.8 × 9.8 in) before the round begins, with specified number of motors and sensors depending on each competition category. It must finish the mission autonomously, within a maximum time of two minutes. Teams are judged on their scores. If two teams' scores are equal, they are judged by their time to the nearest millisecond. This category was called Regular category until 2021.

RoboMission characteristics Three age groups: Elementary (8 to 12y), Junior (11-15y) and Senior (14-19y.) Hardware: Every team builds one robot to solve the challenges on the field. Teams are allowed to use any materials and components to build the robot. Software: Any software and any firmware can be run on the controllers. Maximum robot size: 25 cm x 25 cm x 25 cm. Surprise Rule: A surprise rule will be announced when the competition starts, to test the team's ability to adapt their hardware or programming. (Note: some member countries have a slightly different approach to the surprise rule.) Assembly: As of the 2022 season, assembly of the robots at the competition venue is no longer required Team: A team consists of 1 coach and 2 or 3 team members.

Future Innovators

Future Innovators is a project based competition. Students create their own intelligent robotics solution relating to the current theme of the season. Teams will present their project and their robot model to a group of judges on the competition day. This category was called Open category until 2021

Future Innovators characteristics Three age groups: Elementary (8 to 12y), Junior (11-15y) and Senior (14-19y.) Hardware: No restriction on the balance between LEGO and other elements. Software: Free choice of programming language / software. Maximum size: Teams present the idea in a 2 m x 2 m x 2 m booth on the competition day. Team: A team consists of 1 coach and 2 or 3 team members.

RoboSports WRO RoboSports is a competition where two teams each have two autonomous robots on the field playing a sports game. The two robots of one team may communicate with each other, but no further communication is allowed. The robot needs to be built from LEGO materials and a camera of their choice. The game changes every 3 or 4 years, the current game is Double Tennis.

RoboSports characteristics One age group: 11–19 years old. Hardware: Teams need two robots to participate in RoboSports. The controller, motors and sensors used to assemble robots must be from LEGO sets. Only LEGO branded elements may be used to construct the remaining parts of the robot. In addition, teams will need a camera module. Software: Free choice of programming language / software. Maximum robot size: 20 cm x 20 cm x 20 cm. Assembly: The teams bring their robot completely disassembled. In the first part of the competition they will have 120 minutes to assemble their robots from loose parts without instructions. Team: A team consists of 1 coach and 2 or 3 team members.

Future Engineers WRO Future Engineers is a competition where each team has to engineer and solve real-world-problems. Teams can use any kind of material and controller for their robot. The game changes every 3 or 4 years, the current game is about autonomous driving.

Worked examples

Example 1 — a first encounter with World Robot Olympiad

Start with the simplest possible case. Write down what World Robot Olympiad claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to World Robot Olympiad before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about World Robot Olympiad ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of World Robot Olympiad

In research: World Robot Olympiad appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses World Robot Olympiad in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: World Robot Olympiad is common in secondary-school and first-year university syllabi. It links to neighbouring topics Recurring events established in 2004, Robotics competitions, so understanding it makes those chapters shorter.
In everyday life: Look for World Robot Olympiad outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
