Material for RoboMission

To take part in a competition in the RoboMission category, you need a lot of material:

Since the 2025 season, the free choice of technology has been approved. Until 2024, only LEGO brand sets were allowed to be used, but sets from other manufacturers are now also permitted. The exact specifications of the WRO Association (international umbrella organization) as to which motors or sensors can be used are not yet available. Teams that are considering switching to a different set should check here regularly. Lego robots (SPIKE Prime, Mindstorms EV3 or Inventor, and NXT) are still permitted.

LEGO SPIKE Prime sets can be rented from our webshop .

Note: We expect the exact rules from the WRO Association at the beginning of December. We will update this page and the FAQ accordingly in mid-December.

Important: According to the general rules, a team may only bring one robot chassis to the competitions. A chassis is defined as a construction consisting of the controller / hub / “brick”, motors and sensors. The chassis may be modified during the competition and you may have spare parts with you, but a spare controller must remain with the coach and may only be replaced in the presence of a referee.

• One computer or a tablet with the software required for programming. If a device issued by the school is used for this purpose, permission may need to be requested before the app can be installed; sometimes installation or approval by the school’s IT officer is also required.

When registering for the competition, each team receives a mat; additional mats can be ordered in our store for a fee.

After the end of the season, the used mats will be available to buy as second-hand material; we will then link to them in our store.

For the competitions, objects have to be built from Lego bricks, which then have to be transported by the robot or sorted by color. There are special Lego sets for this. A new set (WRO expansion set, set number 45819) has been available since the 2023 season. The old set (WRO basic set, set number 45811) is also still required. Both sets can be ordered free of charge by new teams when registering for the competition. If additional sets are required, these can be ordered from our store for a fee.

WRO CH rents out robot sets. Whether it’s a one-day workshop, a project week or an entire competition season – we can help you. Details in the store.

In WRO competitions, the mat is placed on a wooden table with a 5 cm high railing. It makes sense to use such a table during preparation. Here are the assembly instructions.

There are two versions of the table: one with a continuous top and one that folds up. If there is no space to store a table outside of training times, there is also the option of making a railing from 4 loosely screwed wooden slats, which can be screwed together and unscrewed with just a few handles. The dimensions correspond to those of the full-length table.
