The robot moves your Innovation Project onto the RePLAY logo or the gray area around the bench (M04).
The robot slides the step counter slow and steady. The farther the “walk,” the better.
Note: R25 BENEFIT OF THE DOUBT
R25 tells the referee how to rule in confusing or hard-to-tell situations.
If the referee’s decision “could go either way,” or if the referee’s preparation, attention, vision, or memory cause an issue, you get the benefit of the doubt.
So far we have covered mainly the technical side of teaching studenst LEGO Robotics. However, another important part is the methodology. How you explain complex concepts to students, how you conduct the classes or how you push the students to constantly improve?
Have you seen the wheel(s) of a car spinning, but the car itself is not moving? Why does it happen?
This is a brief summary of the tasks in the lesson and the experiments with the differential that the students will conduct during the class. Bellow you can find a list of the tasks and what to expect from them. Take a look at them prior to the lesson, so that you there will be no surprises.
The students have already built stands in the previous lesson and it is expected that they will need lesser time to build it this time. They will conduct the same experiments, but as they will use different construction, we can expect different results.
The goal of the lesson is for the students to learn 3 state line following.
Only one score counts.
If the number of Precision Tokens left on the Field is:
(mission descriptions source https://www.first-lego-league.org/)
Only one counts per stack
If an Upgrade (solar panels, roof garden, insulation) is Independent, and Supported only by a Stack which is at least partly in any Circle:
(mission descriptions source https://www.first-lego-league.org/)
Please take the needed time to understand the scoring examples.
If there are any Circles with at least one color-matching Unit Completely In, and Flat Down on the Mat:
If there are Independent Stacks at least partly in any Circles, add all of their heights together:
Note: The Blue Circle is not Part of Mission 12.
Note: A Stack is one or more Building Units with Level 1 touching Flat Down on the Mat, and any higher levels touching Flat Down on the level below.
Color match = no
Tan stack = 2 levels
White stack = 1 level
15 points shown
Color match = no
Bridged stack = 4 levels
20 points shown
This whole stack counts as one independent stack because the white unit is rested on top of the red one. This stack is partially in the circle. It is 4 levels high, so 4x5 = 20 points.
Color match = red
Red stack = 2 levels
Other stack = 4 levels
40 points shown
score one or the other
If there is a team-designed Structure clearly bigger than a Blue Building Unit, built only from your white LEGO bricks
Note: Design and build your own Structure before you compete, then bring that to each Match. You don’t build it during the Match.
Note: Your mission 11 Structure needs to be built from Bag 10 elements only. It can include the red and gray elements. Not all of the Bag 10 elements need to be used.

If the Steel Structure is Standing, and is Independent, and Supported only by its hinges as shown:
(mission descriptions source https://www.first-lego-league.org/)
If the Test Building is Independent and Supported only by the blue beams, and some beams have been knocked out at least half way:
(mission descriptions source https://www.first-lego-league.org/)
Score one or the other
If the Elevator’s moving parts are Independent, and Supported only by its hinges as shown, in the following position:
(mission descriptions source https://www.first-lego-league.org/)
If the Swing is released: 20
(mission descriptions source https://www.first-lego-league.org/)
If the Traffic Jam is lifted, its moving part is Independent, and it is Supported by its own hinges as shown: 10
(mission descriptions source https://www.first-lego-league.org/)
Score all that apply
If a Unit is Independent and Supported by the Tree’s:
(mission descriptions source https://www.first-lego-league.org/)
If the Bat is Supported by branch (B) on the Tree: 10
(mission descriptions source https://www.first-lego-league.org/)
If the Inspection Drone is Supported by axle (A) on the Bridge: 10
(mission descriptions source https://www.first-lego-league.org/)
Score all that apply
If the Hooked Blue Unit is:
Note: You can only get Flag points if you get Bridge points.
Note: Rule 31 allowance: It is okay and expected for Robots to collide while trying to earn Flag points.Note
Note: When clearly only one Robot is holding a Flag raised, only that Robot scores for that Flag
