Description:

The robot moves your Innovation Project onto the RePLAY logo or the gray area around the bench (M04).

Scores:

• if your Innovation Project fulfills the following conditions:
  • Is made of at least two white LEGO pieces;
  • Measures at least as long as four LEGO studs in at least one direction;
  and at the end of the match has any part of it touching either the RePLAY logo or the gray area around the bench: 15

Rules.

Description:

“Doing the same with less” can save time and space.

Scores:

• If all your equipment fits in the small inspection space: 25

Note:

When you get to each match, remove all your equipment from any containers and show the referee you can fit it all in the small inspection space. See Rule 09 for details.

Rules.

Description:

The less often you interrupt the robot outside home, the more points you keep.

Scores:

If the number of precision tokens left on the field is:

• 1: 5
• 2: 10
• 3: 20
• 4: 30
• 5: 45
• 6: 60

Note:

See rules R05, R15, R16, and R19.

Rules.

Description:

The robot collects health units from around the field and moves them to target areas.

Scores:

If health units are:

• Touching the RePLAY logo: 5 each
• Touching the gray area around the bench: 5 each
• Looped over a pull-up bar post as shown – and touching no equipment: 10 each; max 40

Rules.

Description:

Before the match, you hand select the machine’s lever setting. During the match, the robot moves the lever until the little yellow stopper falls.

Scores:

If the stopper is under the lever and lever setting is

• blue: 10
• magenta: 15
• yellow: 20

Note:

The lever setting is the color under the east face of the east green bar.

Before the match starts, you slide the lever where you want, with the stopper on top.

This is an exception to rule R12.
R12 defines where the robot goes between missions and tells what other handling is or is not allowed.

The (imaginary) space labeled “Home” in R13 . It has no ceiling and does not include the white sponsor logo band.

• Home is your space for handling and storing allowable things whenever you like.

• It is also the place for handling and preparing the robot before and between launches.

• After any launch, the robot needs to return completely into home if you want to handle it without losing a precision token.

• The robot can leave home only from the launch area, but it can return home anywhere.

• Do not interact with things outside home except by rules R15 and R19 . Anything the robot affects or moves completely outside home stays as is unless the robot changes it (see rule R19 ).
  Exception 1: If something comes out of home by accident, grab it quickly so it does not upset the field. 
  Exception 2: If equipment breaks off the robot unintentionally, you can pick it up as needed.

• You cannot strategically send or extend anything even partly out of home except by launching the robot.

Rules.

Description:

The robot moves the free wheel out of the large circle and into the small target circle.

Scores:

If the free wheel is:

• Completely outside the large circle: 15
• Completely in the small circle: 30

Rules.

Description:

The robot spins the rollers to move the pointer as far clockwise as possible.

Scores:

If the robot spins the rollers so the pointer points to

• gray: 5
• red: 10
• orange: 15
• yellow: 20
• light green: 25
• dark green: 30

Note:

If a position is not clear, imagine a needle at the end of the pointer. The edge of a color counts as that color.

If the robot moves the pointer by touching the pointer, M11 scores zero.

Rules.

Description:

The robot flips the cell phone white side up.

Scores:

• If the cell phone is white side up and resting on only the mat: 15

Rules.

Description:

The robot flips tires so their white centers face up and moves them into their large target circle.

Scores:

• If the light (blue tread) tire is white center up: 10
• If the heavy (black tread) tire is white center up: 15
• If white-center-up tires are completely in the large target circle: 5 each
• For all scores, the tire needs to be resting on only the mat.

Note:

If the heavy tire crosses the red flip line at any time, even partly, it scores zero.

The flip line runs all the way north to south. Only part of it is shown.

Rules.

Description:

Boccia is an interactive mission with the opposing team. Talk with the other team so the robots send matching colored cubes onto the opposite field.

Scores:

• If both share models have sent only one cube anywhere onto the opposing field and those cubes color-match each other: 25 for each team
• If there are cubes completely in your frame or target: 5 each cube
• If there is at least one yellow cube completely in your target: 10 added

Note:

If there is equipment even partly in your frame, M08 Boccia scores zero for you (the opposing team is not affected).

If, like most teams, you have only your one practice table, your sent cube will simply go over your north wall during practice.

(Study the scoring examples as if both share models did share only one cube.)

Rules.

Description:

The robot is dancing on the dance floor at the end of the match.

Scores:

• If the robot’s controller is at least partly over the dance floor in a “dancing” motion at the end of the match: 20

Note:

Any silly or skilled repetitive action counts as dancing – do something fun! For M07, you cannot score this plus the “held up” score from M06 Pull-Up Bar in the same match.

Rules.

Description:

The robot passes completely under the bar any time. Separately, it is held off the mat by the bar at the end of the match.

Scores:

• If the robot passes completely through the pull-up bar’s upright frame at any time: 15 max
• If the pull-up bar holds 100% of the robot up off the mat at the end of the match: 30

Note:

For the “held up” score, you cannot score this and M07 Robot Dance in the same match.

A “pass through” can score northward or southward, but only one way and only one time. A “pass through” scores at the time it happens. This is a rule R22 exception.

R22 cautions you that if the robot’s accomplishments are wrecked before the match ends, they will not score.

Mission requirements must be visible at the end of the match to count unless a method is required.

• Precisely as the match ends, everything needs to freeze in place for examination.
• Stop the robot, leave it as is, and then keep hands off everything as the referee scores the field with you.

Rules.

Description:

The robot raises the crate up the post and gets a cube into it.

Scores:

• If there is a cube in the crate: 15
• If the crate rests on the middle height’s white stopper: 15
• If the crate rests on the top height’s white stopper: 25

Note:

Only one cube can score in the crate.

Score top height or middle height, not both.

Rules.

Description:

The robot removes the backrest, flattens the bench, and gets cubes into the hopscotch spaces.

Scores:

• If the bench is down flat: 10
• If the bench is down flat and there are cubes touching the mat in hopscotch spaces: 10 each space
• If the backrest is completely out of both of its holes: 15

Rules.

Description:

The robot slides the people (called “slide figures”) down the slide and moves them to other areas.

Scores:

• If only one slide figure is off the slide: 5
• If both slide figures are off the slide: 20
• If a slide figure is completely in home: 10 max 
• If a slide figure is held completely off the mat by the heavy tire and is touching nothing else: 20 max

Note:

Off the slide” scores if the slide figure’s black frame is past/ below the tip of the slide’s gray slide part.

Notice the score for two slide figures off is 20, not 25.

Rules.

Description:

The robot slides the step counter slow and steady. The farther the “walk,” the better.

Scores:

• If the bottom of the pointer is on magenta: 10
• If the bottom of the pointer is on yellow: 15
• If the bottom of the pointer is on blue: 20

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.

Rules.

Scores:

If the Swing is released: 20

(mission descriptions source https://www.first-lego-league.org/)

Scores:

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/)

Scores:

Score all that apply

If the Hooked Blue Unit is:

• Clearly lowered any distance from the Guide Hole: 20 and
• Independent and Supported by another Blue Unit: 15 and
• Level 1 is Completely in the Blue Circle: 15

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

This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever. 

Here is Lintu. It is a marvelous LEGO Mindstorms EV3 Animal robot that looks like Kiwi, the famous New Zealand bird. It is quite rare to see a Kiwi bird in person. But fear not, we've prepare a robot that looks almost exactly like the original.

Here is Comet. It is a fast LEGO Mindstorms EV3 Car robot that looks like F1 Racing Car. We've especially designed it to be controlled with the remote control to make it extremelly easy to download the program and start playing with the robot. It also has the option to "press the pedal" (increase the speed) with just the remote control. Check it out.

Here is Turtle - a LEGO Mindstorms EV3 robot that is designed to look like a sea turtle (may look clumsy but it's not). It has two sensors - ultrasonic and gyro, capable of following its course and navigating through anything. It can even get "angry", if you annoy it too much.
