The FIRST LEGO League (FLL) is an international competition organized by FIRST for elementary and middle school students.

In September each year, a new challenge is announced that focuses on a different real-world topic related to the sciences. This year theme is animals.

Each challenge within the competition then revolves around that theme. The robotics part of the competition revolves around designing and programming Lego Mindstorms robots to complete tasks.

The students work out solutions to the various problems they are given and then meet for regional tournaments to share their knowledge, compare ideas, and display their robots.
