ROBO LEAGUE fri 2026: Construction site

It was the year 2026. Construction of a new residential neighbourhood had begun. The goal was clear: to create a modern neighbourhood that would also be green and environmentally friendly. That is why construction workers are joined by environmentalists, who make sure that new trees are planted alongside the construction work.

With little time to spare, both teams have entrusted their work to autonomous robots. The construction robots collect bricks and iron and deliver them to the construction base, while the environmentalist robots plant trees around the construction site. As trees are also planted along the construction robots' routes, they must skilfully navigate around them and make sure not to collide with any.

The final inspection will take place on 3 December 2026. Will the construction workers manage to deliver enough materials and the environmentalists plant enough trees? Join us at FRI and see how the robots perform.

This year's challenge takes the robots to the construction site of a new residential neighbourhood.

Each team builds its own autonomous robot, which takes on the role of either a construction worker or an environmentalist. The robots compete on a playing field representing a construction site, with construction materials, namely bricks and iron, scattered around it.

Two autonomous robots compete at the same time: a construction worker and an environmentalist. At the start of the match, the environmentalist has trees at its starting base, which it plants around the playing field during the competition. On the other side of the playing field is the construction base, where the construction worker attempts to deliver the scattered construction materials. As more and more trees are planted, the construction worker must continuously find a suitable route to the materials and the construction base while making sure not to collide with the trees.

The robots navigate the playing field using data received from a server via a wireless network. The server monitors the action on the playing field using a camera mounted above it.

PROCEDURE AND REGISTRATION

Register your team through the online registration form.

The registration deadline is October 18, 2026.

A few days after the registration closes, registered teams will be informed about the date and location of the introductory meeting. During this meeting, we will explain the competition rules and process in detail and distribute Lego kits to the participants.

Competition teams can have up to three members. Year of study, program, or faculty do not matter. Up to 12 teams will be selected from those who apply. Teams with their own EV3 kit are guaranteed a spot. If you don’t have your own EV3 kit, we will lend you one for the duration of the competition.

FRI students can earn 3 ECTS credits through active participation or by assisting with the organization (as part of the courses Computing in Practice and Extracurricular Professional Activity).
