Robots built with construction manual
11.08.2017 - 13:22 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!

Turn off the robot
13.02.2017 - 10:55 Uhr



Can the team turn off the robot before the match is finished?

If the team decides to turn off the robot, then it is an influence (R14). If the robot is not completely in the base the team will get a penalty. R14, however, allows the team to decide whether to leave the robot where it is or to return it to the base.


Evaluation software

Maximum Score
10.11.2016 - 16:10 Uhr


What is the maximum score that can be achieved with the robot game?

We asked our partner FRIST for the maximum number of points to be reached. The maximum number of points is not calculated by FIRST, so that this number will not discourage anyone from taking part in the competition or deterring anyone. Accordingly, the total score is not published.

Junior coach
10.11.2016 - 16:11 Uhr


Is it possible to become a junior coach with 17 years?

A team can be supervised by several coaches and / or mentors. But there is only one "official" FLL coach who registers the team and is in contact with us. He/she gets all the important information about the contest and for he/she is the person in charge during the tournament. But he/she can get support and advice from other coaches or mentors. But it is important: coaches and mentors should guide the workflow of your team, but should not proposes any solutions. They should "coach" but stay out of the substantive work of the team. We are delighted to support former team members who wants to be involved with the coach job.

Evaluations sheets
10.11.2016 - 16:11 Uhr


Where can I find the evaluation sheets?

You'll get the evaluation form by following the link By clicking on the category name for example "Robot Design" you will find the link (orange) to the respective evaluation form.

Variations of the FLL Tournament Tables
10.11.2016 - 16:12 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.


Sea level rise
30.08.2017 - 15:18 Uhr

Could the sea level rise be a topic for our research project?

The potential for sea level rise is an issue of great concern for many communities. In order for this subject to be an acceptable project topic, your team should be able to relate sea level rise to a problem of the human water cycle. Please remember to focus on a human use of water.

Narrowing your focus
30.08.2017 - 15:18 Uhr

Can our team focus on only one phase of the human water cycle?

While the definition of the human water cycle includes four phases (“find, transport, use, and dispose”), your team does NOT have to investigate all of these part of your project. You may focus on one or more parts of the human water cycle when identifying a problem and designing a solution.

Fresh water vs. salt water
30.08.2017 - 15:18 Uhr

Does salt water also belong to HYDRO DYNAMICSSM?

The HYDRO DYNAMICSSM project is not limited to the study of fresh water. Teams may explore a use of fresh water, brackish water or salt water. However, the problem your team selects should be a part of the human water cycle. The human water cycle is defined as, “the ways people find, transport, use, and dispose of water in order to meet a specific need or desire.” So, whatever type of water your team selects, you should be able to clearly demonstrate how the water is used to meet a human need.

No research project or missing the target of the research project
10.11.2016 - 16:13 Uhr


Are there any consequenses if a team does not prepear 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'.


10.11.2016 - 16:14 Uhr


Can we pick us any topic we like?

No, the topics are limited to the topics listed in the research project documents.

Material for judges
10.11.2016 - 16:14 Uhr


Do we have to prepare some written material or our presentation in written form for the judges?

No, you don´t have to produce a written material for the judges. Important is the presentation and its content you perform for the judges.

Analyse problem and present results
14.11.2016 - 13:35 Uhr


What includes the presentation?

Each team should show on which way they found the specific problem. Show how you researched and came to a soulution for the problem you chose. It is not enough to present only the result.

Duration of Research Presentation
10.11.2016 - 16:15 Uhr


How much time do we have for the presentation of our research results at a FLL Tournament?

At a FLL Tournament you have 5 minutes time (actual presentation time, not set up time) to present your results to the jury. The manner of presentation is up to you - you can create a role play, use Powerpoint and so on. Give your presentation live - you may use media equipment (if available) but only to enhance the live presentation.

The technical approach of the research project
10.11.2016 - 16:23 Uhr


Does the research project has to have a technical approach?

No, the research project does not have to contain a technical approach.

10.11.2016 - 16:27 Uhr


Shall we name our sources? Do the sources have to be part of the presentation or is it sufficient to show them at the end of the presentation?

Yes, a good presentation shows at the latest at the end all the sources the team had worked with during their research project. The sources should also be part of the 5 minutes presentation. 

Obligation to publish
10.11.2016 - 16:27 Uhr


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

Each team is obliged to publish the results ahead of the tournament. This can happen in several ways: presentation in front of parents, students, teachers or the interviewed experts, write an article or make a website or blog etc. The team should show the form of publishing within their presentation e.g. by a photo.


R11: Dismounting the loop from the yellow pipe
12.09.2017 - 16:25 Uhr

Is it allowed to dismount the loop from the broken yellow pipe (M01) to reuse it another way?

No, please keep the proprieties, R11: “You are not allowed to take mission models apart, even temporarily.”

R14: Handling of the mission model after interruption
04.09.2017 - 15:02 Uhr

Update of rule R14 "Interruption"

If you interrupt the robot while it’s transporting a mission model that came from Base during the most recent launch, you may keep that model.

In this case, you would be able to bring the model back with you to Base along with the robot!


Ceiling of the Base
01.09.2017 - 10:45 Uhr

Is the ceiling of the Base valid for every start?

The change under 1.6 for 2017/18 says “Maximum equipment height UPON LAUNCH is now limited. (R13)”

At R13 launch and re-launch are regulated – the ceiling of the Base (12 inches/30.5 cm) holds for every launch – that means: Also for relaunches during the Robot Game.

This new rule is only formulated for starts, so for returns to the Base holds rule D07 (2nd item “no ceiling”).

D06: Areas between field and table
10.11.2016 - 16:29 Uhr


D06: Does the area between the north of the playing field and the table belong to the playing field?

Yes, this area belongs to the playing field. You'll find more details here. Please ask the regional partner for information, too.

“Totally in”
11.08.2017 - 12:02 Uhr


When is an object “totally in” a target area?

The diagrams in rule D7 define completly in for the Base but apply for any other target area.

Rules readable
25.07.2017 - 14:57 Uhr


What are the rules for FLL and where can we find them?

With the challenge release at the end of August (29.08.2017) there will be all FLL Rules available online

If you want to be successful in the FLL Robot Game it´s extremly important for everyone to read the challenge documents in detail: Rules, Missions, Field Setup & Playing Field (which are together in one document this year), Questions & Answers. THE TEAMS, READING EVERYTHING have fewer questions, have less work, have fewer surprises at the tournament, score higher and have more fun.

Playing Field & Missions

Gap between target and border wall
20.09.2017 - 10:13 Uhr

Does the gap between the target on the mat and the border wall also belong to the target?

Yes, the gap between target and border wall also belongs to the target, respectively. So the target is theoretical “extended” to the border wall.

M07 Fountain – Evaluation
20.09.2017 - 15:13 Uhr

Will it meet the requirements of “M07 – Fountain” if only the uppermost part of the fountain is raised?

No, for this mission it matters that at the end of the match the middle layer rises some obvious height.

Return to Base
06.09.2017 - 09:10 Uhr

Does the robot return to the Base after each mission?

No, the robot can return to the Base as often as you want. He does not have to do this after every mission. It can also combine several missions. This saves time.

Mission M02 “Flow”: end condition
12.09.2017 - 08:37 Uhr

What happens if the “big water”, which we placed on the other team's field with the help of the pump system's valve(s), is moved by the other team and used for the fulfillment of tasks. The referee could not see this “big water” at the end of the match.

For the evaluation of task M02 Flow, it is crucial that by turning on the valve (s) of the pumping system a large water is transported to the playing field of the other team. So it counts the action itself, not what is visible at the end of the match.
