In this level, we will explore the color sensor and different LEGO robotics competition categories. If you have ever participated in a competition, feel free to share fun stories with your students. If you haven't, use this level to familiarize yourself with competition robotics and perhaps consider participating one day!
During most of the lessons (excluding lessons 1 and 4), you will need a special mat, which you can find here: [link]. You can also use your own mat, as long as it serves the purposes of the lessons.
In this lesson, students are introduced to the color sensor. The task is to program the robot to stop at the green bottle using the Color Sensor Event Block. Instructions for building the bottles (loops) are provided below, and we recommend building them yourself beforehand. You can build a few sets if you have a large number of students, but it's not recommended to have the students build their own bottles due to the abundance of new material and time constraints. Here's an example solution for the program:

Level B2 - Introduction to Robotics Competitions - Robotics with LEGO SPIKE Prime
This is the fourth level of the LEGO Robotics Curriculum for students in second, third, or fourth grades.
Competitive Introduction Level: Each lesson has a theme related to various LEGO robotics competitions. Students learn about FIRST LEGO League, Line Following, and Sumo Wrestling. A new color sensor is introduced, and students use forever loops, wait until commands, and if/else statements in new ways.

Lesson 1 - Color Sensor
Introduction
In this level, we will learn how to use a new sensor - the COLOR SENSOR! We will also explore various robotics competition disciplines, such as FLL, Line Following, and Sumo!
Have you heard of any of these competitions? Would you like to participate in any of them?
We will start with the namesake of this site - FLL. FLL stands for FIRST LEGO League. An FLL competition has four categories: Research Project, Core Values, Robot Design, and Robot Game.
We will focus on the Robot Game, which takes place on a special field, like the one in the picture. The field has multiple missions that the robot should accomplish to score points. The robot that scores the most points in 2 minutes and 30 seconds wins.
Every year, FLL has a new theme, which changes the entire Robot Game Field. Teams have a few months to prepare their robot before the actual competition begin.
