FLL Robotics Season 2021-2022


This year’s FIRST LEGO League challenge is called CARGO CONNECT. You will learn about how goods are transported, sorted and delivered to their destinations. With increasing demands on transport systems, we need to rethink the way goods are transported from one place to another. Your critical thinking combined with imagination sets the stage for fun and active lifestyles for everyone!


Read the missions and decide your strategy on the ground. For example, if you can earn 4 points when a mission model hits the mat, your team can design a robot that can knock it over on the mat, gently place it on the mat, roll it on the mat, etc. If the rules don’t forbid an idea, it is permissible.

Read the rules. They explain how a match should be conducted and detail the constraints placed on robot parts, team gestures, robot action and scoring.

Plan, build and schedule; test, repair and re-evaluate; repeat! Explore, have fun while looking for solutions.

Do repeated actions produce the same results? Make sure the robot and its mechanisms are robust.

Plan for simple programs that allow your team to successfully execute the transitions between mission sequences.

Document how your robot evolves in your engineering booklet. To help Robot Design judges quickly and completely understand your robot and the design process used, you can prepare a short poster/sketch to accompany you presentation. An “executive summary” is often used by engineers to briefly describe the key elements of a product or project. The purpose of the summary is to give the Robot Design judges an overview of your robot and all that it can do. You cannot share in 5 minutes everything that your team did. You have to determine in advance the most important information to share with the judges.


The executive summary is NOT meant to be as comprehensive and long as your Project. Do not provide a written version of it. Try to make it interactive and involve ALL your team members. The entire presentation, including a small demonstration of the robot features, should not take more than five (5) minutes. Following your presentation, the judges will ask questions.
The executive summary should include the following:

Robot basic characteristics: the number and type of sensors, the basic capabilities of the robot base, and the number of mechanisms. Judges would also like to know what programming language you are using, how many programs and how you run them(one by one, mission chains).

Design Details:

  1. Fun: Describe the funniest or most interesting part of robot design as well as the most difficult parts. If your robot has a name, who chose the name and why. If your team has a funny story about the robot, please share it.
  2. Strategy: Explain your team’s strategy and reasoning for choosing and carrying out missions. Talk about your robot’s success in completing the missions you have chosen. What is your favorite mission and why.
  3. Design Process: Describe how your team designed the robot and the process you used to make improvements to your design over time. How the different team members contributed to the design. How did you integrate the ideas.
  4. Mechanical Design: Explain to the judges the basic structure of your robot, is your robot easy to repair or add / remove mechanisms. Explain to the judges how the robot moves (controllable base), and what parts or mechanisms it uses to carry out the missions.
  5. Programming: Describe how you programmed your robot to ensure consistent results. Explain how you have organized and documented your programs; Indicate if your programs use sensors to precisely locate the robot in the field.
  6. Innovation: Describe any features of your robot design that you find special, different, or particularly clever.
    Demonstration: Demonstrate to the judges how your robot works during the mission (s) of your choice. Don’t play a full game; give the judges time to ask questions of your team. The judges will not consider the robot’s performance here as in matches.
