Žalgiris Robot Battle 2026

On May 9, an international robotics competition will be organized on the Science Island.

9:00 registration of competition participants begins

10:00 competition begins

Participant registration will be carried out until May 1.

We are waiting for both participants and robotics enthusiasts from all over the world!

Have you ever dreamed of seeing a robot fight live? Or maybe you like speed and robots that fly like Formula 1 cars? Would you transfer the fight strategy to the sumo robot code?

We invite all robotics enthusiasts, technology lovers and the curious to come on May 9. There will be something to do not only for participants, but also for spectators. Here we will see both robot fighters, super-fast line followers, and sumo wrestlers with strength and strategy.

Have you ever heard that robots are only for boys? We are breaking these outdated stereotypes and inviting female robotics teams to participate in a new event – Fire Sisters.

12 different categories of robots will compete in the Žalgiris Robot Battle 2026:

Antweight 200g* – the goal of combat robots (up to 200 g) in this competition is to disable the opponent robot within a 3-minute match in a confined arena. Here, precision of control, reaction time, and the ability not only to act strategically but also to utilize the robot’s technologies – such as defense and weaponry simultaneously – are especially important.
Antweight 454g – the category of more powerful combat robots (up to 454 g) involves competing to push or disable the opponent so that it cannot move. The higher weight allows for more complex engineering solutions and more effective weapons. Here, the ability to control the robot remotely, the durability of its construction, energy management, and combat strategy are all crucial.
Line Tracking* – robots must navigate the track autonomously, following a marked line to complete the course as quickly and accurately as possible. In this competition, the robot’s precision, programming, and ability to maintain a balance between speed and control are crucial.
Line Tracking TURBO – a faster and more advanced line-following event, where robots aim for maximum speed on the track. Additional turbines are used here to keep the robot pressed against the track, making this category require more precise programming and extremely quick robot reactions.
Mini SUMO* – an autonomous robot (up to 500 g) duel in a sumo ring, where the goal is to defeat the opponent. Various sensors and special metal blades are used to achieve this. In this category, a strategically designed structure capable of lifting the opponent, programming, and quick reaction are all important.
Lego SUMO – a robot competition using LEGO-type construction kits, helping participants take their first steps in robotics and test their skills in battles. Teams design and program autonomous robots that compete in the ring, combining construction, sensors, and programming skills. Participants compete in different categories – LEGO Sumo Junior (up to 12 years) and LEGO Sumo (12 years and older).
Micro SUMO – a battle of the smallest autonomous robots (up to 100 g) on a sumo ring, where they must detect and push the opponent out of the arena. Due to the strict size and weight, this event demands a high level of skill, as participants design extremely compact robots.
FORVIA HELLA Folkrace – autonomous robot races on a closed track bounded by walls. The goal is to complete as many full laps as possible in the correct direction within set time (3 minutes), while avoiding obstacles and other robots. This event simulates a car rally – up to 5 robots can race on the track simultaneously, competing for the highest score.
Fire Sisters – a unique event, held for the first time in Lithuania, designed specifically for girls. In teams, they will build autonomous robots capable of locating and extinguishing candles in a special competition arena. Within a limited time, participants must navigate obstacles and complete the task as accurately as possible, showcasing engineering solutions, programming skills, and logical thinking. Each team can have up to 6 members.
Freestyle – a technological project and robot presentation event with no technical restrictions. Here, the most important aspects are the idea and its execution, creativity, innovation, critical thinking, and the ability to present the project within a short time.

* Participants in these events, depending on the number of participants, may be divided into separate age groups.
