Attention all French speaking teams! Update to "LEGO MINDSTORMS Education EV3 Classroom" software

In the engineering notebook on p. 11 in the right column of the "LEGO MINDSTORMS Education EV3 Classe" software, different terms are used than in the online version of the software.

The reason for this is that at the time of going to press, the software "LEGO MINDSTORMS Education EV3 Classe" was not yet available in French.

You can find the software here:

The desired language can be set under "Help".


The software "LEGO MINDSTORMS EV3 Education" has been replaced by the new software "LEGO MINDSTORMS EV3 Education Classroom", which works with the coding system "Scratch". Teams using the old version can continue to do so. However, it is no longer supported with updates.

Important Information: EV3 on MacOS
20.04.2020 - 10:46 Uhr

Important Information: EV3 on Mac Operating Systems (MacOS)

Dear Teams and Partners,

LEGO Education has an important announcement for FIRST LEGO League teams working on Mac Operating Systems (macOS). Please read the message below carefully and share with your teams where necessary.

The current version of the EV3 Lab software is not compatible with the upcoming update to macOS, called Catalina. We are therefore introducing a brand-new EV3 app in November 2019, called LEGO MINDSTORMS Education EV3 Classroom. Based on the SPIKE app, EV3 Classroom will feature a coding language based on Scratch that we are confident will unleash the full potential of EV3 in the FIRST LEGO League program. The first release of EV3 Classroom will be in US English, followed by the other 15 EV3 languages in spring 2020.

To continue to enjoy an uninterrupted EV3 experience and to avoid losing your programs, we strongly recommend that you do not update to Catalina until the end of the FIRST LEGO League season in July 2020. If you have already updated to the new OS, please contact T​​echnical Consumer Service at to discuss how we can help you during this transition period.

For further questions and support, we encourage you to reach out to Technical Consumer Service using the link above.

Do coaches need to know how to program a robot?
20.04.2020 - 10:46 Uhr

As the coach, do I have to know how to program the LEGO robots myself?

No. It’s not difficult to pick up the basics of the MINDSTORMS software, and it’s up to the team members to find the information they need to complete the challenges.

The latest version of the LEGO Mindstorms software has a Getting Started section with very useful lessons.

Download the latest version of the software.

Newcomer team - can we pull out?
20.04.2020 - 10:46 Uhr

My team are new and don’t think they’ll be ready to compete at the tournament. Can we pull out?

As long as your team have made an effort at tackling the project and robot game in the spirit of the Core Values, they will learn a lot from attending the tournament and will enjoy the day. The aim of the tournament is to celebrate the work that the students have done. All tournament staff will be working hard to make sure that there is a positive, encouraging atmosphere, so whether the team win an award or not they should come away feeling good about their work. If they’ve enjoyed working on the challenges and have fun at the tournament then you will have completed a successful first year in FIRST LEGO League, and should be well placed to go again next season!

Robots built with construction manual
20.04.2020 - 10:46 Uhr

What happens with robots which are built with the aid of a construction manual?

Teams who build a robot with the aid of a construction manual must expect the robot not to be rated as the team’s own creative achievement in the category robot design.

At this point, it should also be noted that the circulating construction manuals often refer only to basic robots that meet the specific requirements of the actual season only inadequate.

So: no plagiarisms! Because what counts in the category robot design is the team’s creative achievement at programming and design!

Where can I find the scoring sheets?

To get an impression of what to expect in the Robot Game scoring, you can have a look at the scoring sheets here.

Variations of the FLL Tournament Tables
20.04.2020 - 10:46 Uhr

Are the FLL tables identical at all tournaments?

Please consider while constructing and programming that there can be variations between different tournaments depending on local conditions. The variations might occure in differenciations in the character of the field borders, lightning conditions, structure/irregularties of the field mat. At many tournaments there is no opportunity to roll out the mats early enough so that they might be a little bit wavy. Place and severity of waves can vary.

Hint: There are two important construction techniques to minimize differences in illumination:

1. Avoid control systems containing something that might rub on the mat.
2. Hide light sensors from ambient light.

Questions according the local conditions at regional tournaments can be posed directly to the local organiser. Please find there contact dates on the regional websites.


Missing target of research project
20.04.2020 - 10:48 Uhr

Are there any consequenses if a team does not prepare a research project? What will happen when a team misses the target of the research project?

A FLL team should take part in all categories of evaluation. When a team doesn't have a research project (or doesn't take part in another category of evaluation) it could not become a FLL Champion and will not be evaluated. in the particular category. All teams should act as the core values told them.

If a team fails the research project it still could be evaluated by the judges for presentation but not for “research” and not for “innovative solution”.

Obligation to publish
20.04.2020 - 10:48 Uhr

Are we obliged to publish the results ahead of our presentation on the tournament day?
