So far, we’ve explored a line-following algorithm commonly referred to as duck walking. Let’s take a closer look at how it works and consider how many distinct states it actually involves.
In more advanced robotics programming, your robot may need to respond in three or more different ways depending on sensor input. Up to this point, we've created programs with only two possible outcomes using a switch block: a condition is checked, and the robot performs one action or the other based on the result.
But what if the robot needs more than just two responses? To handle this, we can use multiple conditions—often implemented with nested switch blocks or structured decision chains. In this section, we’ll explore how to build programs that go beyond binary choices and enable your robot to react intelligently to more complex environments.
When you hear the task “program the robot to follow a black line,” you’ll most likely imagine a program that works like this:
In this video tutorial, the MiniBox box robot accomplishes M14 and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge robotics competition. The robot is a LEGO Education SPIKE Prime robot. In this run, the robot delivers the LEGO minifigures to their designated places.
In this video tutorial, the MiniBox box robot accomplishes M08, M14, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge robotics competition. The robot is a LEGO Education SPIKE Prime box robot. In this run, the robot delivers the LEGO minifigure to its designated place and then pushes the M08 camera down the track to shoot the movie scene.
This is a 10 out of 10 tutorial in which the MiniBox accomplishes M14 and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge robotics competition. The robot is a LEGO Education SPIKE Prime box robot. In this run, the robot should consistently and reliably deliver the LEGO minifigures to their designated places.
In today's lesson, we selected a field that introduces a new challenge: it includes a skip section at a turn. To complete today's challenge, you can either modify the program provided in previous lessons or create a new one entirely on your own.
The next level of difficulty introduces self-crossing paths and bending lines. At this stage, we’ll create our first and simplest memory-based program.
For this challenge, it is assumed that the field layout is unknown before the competition, making it impossible to hardcode a specific sequence of turns.
The main difference between this field and the easier one is the addition of crossroads. Crossroads introduce a new level of difficulty that can be overcome by programming the robot to remember the paths it has taken, although there are simpler and more elegant solutions.
For this challenge, it is assumed that the field layout is unknown before the competition, making it impossible to hardcode a specific sequence of turns.
The main takeaways from today's lesson are how to alternate between following a line and performing other actions needed to complete the basic level of the line-following challenge, and how to plan your program ahead of time. Today's program will serve as a foundation to build upon for solving more advanced line-following challenges.
Then the problem lies in other external factors.
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.
Wheel condition plays a crucial role in the performance of any robot, so it’s common practice to maintain your robot before testing and especially before a competition. Here are some steps you can take to ensure that any variations in the robot’s performance aren’t due to the wheels:
