What is FIRST ® LEGO® League?

In FIRST LEGO League, children are immersed in real-world science and technology challenges. Teams research and design their own solution to a current scientific question or problem while they also build and program autonomous robots using LEGO® MINDSTORMS® technology to perform a series of missions.

Through their participation, children develop valuable life skills and discover exciting career possibilities, while learning that they can make a positive contribution to society.

HYDRO DYNAMICSSMHYDRODYNMIC logo

FIRST LEGO League teams undertake a two-part Challenge based on a real-world topic. During the HYDRO DYNAMICSSM season, teams explored how to improve the ways people find, transport, use, or dispose of water, all while operating under the FIRST LEGO League signature set of Core Values, emphasizing teamwork and good sportsmanship.

The Project

FIRST LEGO League teams research and solve real-world problems just like scientists and engineers. Each team was asked to:

  • Identify a problem within the human water cycle
  • Design a solution that makes this problem better
  • Share your problem and solution with others

The Robot Game

Teams built and programmed an autonomous robot using a LEGO® MINDSTORMS® kit to solve a set of missions on a playing field. Each mission represents the amazing engineering used to protect the most precious liquid asset – water.

The Robot Game Missions

In the Robot Game, teams can earn points if the field shows the following at the end of a 2.5-minute match.
