Seon - SPIKE Prime Line Follower

A simple line-following robot, Seon, can be programmed to follow a line. However, its design does not support basic wobble or "ducky" line-following, requiring a more advanced method instead.

Courses and lessons with this Material

This Material is used in the following courses and lessons

Line Following

This is the Line Following course, where you’ll explore essential techniques to help your LEGO robot follow a line with accuracy and stability! We will begin by covering the fundamental concepts of line following, starting with basic wobble line following, which teaches how robots detect and respond to lines. Then, we'll progress to more advanced methods like proportional line following, allowing smoother tracking by adjusting speed based on error values. Finally, you'll dive into the widely-used PID line following technique, where you'll learn how to tune parameters for optimal robot performance. Whether you're a beginner or looking to enhance your robotics skills, this course will guide you through building, coding, and refining your robot's line-following capabilities.

Proportional Line Following

From programs that rely entirely on proportional line following to those that use a PID-type program where "P" stands for the proportional line following component, proportional line following has proven to be a core mechanic in line following competitions.

PID line following

PID is the most popular method for programming line-following robots. It’s a bit complex, so this tutorial is longer, as we’ll break it down into steps and explain each element of the equation.

This approach to programming line-following robots is not ideal for beginners. Attempting to learn this as a first step in competition preparation may give a misleading impression of the competition's complexity and could discourage students from learning the necessary skills to compete in this category.

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 2 - Detecting a line

Introduction

In this lesson, we will program the robot to stop at a line. This technique is used in multiple competitions, such as Line Following, FLL, and Sumo.

Can you think of other scenarios where a robot might need to detect lines? What are the benefits in those situations?

A robot can, for example, detect street markings to avoid getting lost on the road. In FLL, detecting lines is particularly important so the robot knows exactly where it is on the field. Every robot has a small margin of error; each time we move a motor, it might move a bit more or less than intended. You have probably seen this in action, but in these lessons, we create small programs where this error isn't a big problem. However, in FLL, programs are often very long, and this error accumulates until the robot doesn't move correctly at all. That's why we use alignments, usually to walls or lines. When the robot aligns, it corrects most of this error and can continue accurately on its path.

Lesson 3 - Stop at the third line

Introduction

In this lesson we will program our robot to stop at the third line. Why is this challenging?

You'll understand when you start programming. But why do we need this? Although it is sometimes used in different competitions, the real value lies in the concepts this task teaches. It seems simple, yet most students need help when programming it. This task helps you understand how robots work on a deeper level.
