- 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.
FLLCasts Tip
Before the round you will need to set the machine to a desired level. There are 3 "lelvels" - "easy", "medium" and "hard". There is an increase in the difficulty of the mission as well as the points awarded
There are two intuitive ways to accomplish this mission. The first if to push the lever down. The second is to go to the other side of the mission model and lift the tires. The second is easier because the robot needs less force and it can align to the wall

FIRST LEGO League 2020-2021 RePlay Solutions and review with SPIKE Prime
This course presents Solutions and Review of the FIRST LEGO League 2020-2021 RePlay competition. We do such a course every year after the competition. By moving through the course lessons, building the robot and attachment and completing the missions you will learn how to achieve FLL mission following good engineering principles for building robots, attachments and developing programs. Upon completion of the course you will have many new ideas about how to approach mission on every FLL robotics competition and how to help your team score more points.

M13. Weight Machine
In this LEGO robotics video tutorial we accomplish Weight Machine mission from the FIRST LEGO League 2021 RePlay robotics competition. The goal of the competition is to lift a weight. The mission model resembles a weight machine, and is actually a lever. There are three different levels and you earn different points depending on the level. The attachment for this mission model uses rubber bands and lifts the mission model.

FIRST LEGO League 2020-2021 RePlay Solutions and review with Robot Inventor
This course presents Solutions and Review of the FIRST LEGO League 2021 RePlay competition and it uses LEGO MIndstorms Robot Inventor as a base. It is a mirror course to the LEGO Education SPIKE course for the same competition. For each mission in the competition the course contains the rules for the mission, a tutorial how to accomplish it, instructions for the robot that is used and instructions for the attachment that is used. Every lesson also contains a Scratch and a Python program for accomplishing the mission and of course a 10 out of 10 tutorial that demonstrated how reliable the approach is. Upon completion of the course you will have many new ideas about how to approach mission on every FLL robotics competition and how to help your team score more points.
