Video tutorials, Courses, Materials and Programs

We start a course for following a line with crosses and gaps. This is a challenge that one of the users at FLLCasts.com was trying to accomplish and asked us for advice. We present the whole challenge to you step-by-step. But first, let's also see the whole run of the line following algorithm. With this course, we also do an introduction of using State Machine as a programming pattern.

Looking at the field we must first think of a strategy of solving this line following problem. There are rules that the robot must follow and these rules should be programmed in the robot. 

We discuss the state of "Lost" and the different ways we could escape this state. We also build the next step of our State machine programming pattern where the next state is determined by the previous state.

In this episode we do a full run of the mission for collecting a single treasure before going into explanation on how we have programmed the robot.

Implement the program for array initialization.

Follow the video tutorials for initializing arrays and implement the program. 

Implement a program for stopping at a black line with the blocks containing the implementation details for the InitArray, Calibration and Getting the calibrated result. 

The goal of this lesson is to introduce students to the setting for measuring the reflected light of the color sensor and to recall how to follow a line.

In this LEGO robotics video tutorial we will accomplish mission 8 from the FIRST LEGO League 2020 RePlay competition. The name of the mission is Boccia. What you will learn from the video is how to accomplish complex missions that require following a line, aligning to the line and accomplishing many mission models in a single run

This LEGO robotics video tutorial is a 10 out of 10 run of the one of the most complex missions at the FIRST LEGO League 2021 RePlay competition. As the mission has three parts we are measuring the success rate of each part of the mission. What you can learn from this tutorial is how to achieve three missions in a single run including line following and a lot of aligning

10 out of 10 video tutorial for Rowing Machine mission from the FIRST LEGO League 2021 RePlay robotics competition. In the tutorial you will see how to accomplish the mission almost every time. This is a mission that requires a lot of precision so naturally it is difficult to accomplish it every time, but with the right attachment for the LEGO Education SPIKE Prime robot it is achievable

This is a 10 out of 10 video recording about the FIRST LEGO League 2020 RePlay competition and the mission called Boccia Target. We are using LEGO Mindstroms Robot Inventor. The 10 out of 10 recording shows how reproducible the solution to the mission is. You will see a demonstration of a complex attachment that does 3-4 things at once - it alights, pushes, drops, which are all things that are commonly seen at FLL competitions.

In this video tutorial we discuss probably the most useful principle that we've found for FIRST LEGO League competitions and this is how to align to a line with two color sensors. We use the LEGO Mindstorms Robot Inventor for a quick demonstration of the principle. In the LEGO Mindstorms Robot Inventor Programming course we enter into more details of how exactly we program the sensors. The current tutorial demonstrates the use of such a program and makes clear why this could be very useful and is a must for any well prepared team and wants to achieve a good score on the competition.

This video tutorial demonstrates again the consistency of the program for aligning to a line. We run it ten time. We the robot is always coming from the left it is always arriving at the same position. When it is coming from the right it is always arriving at the same position.

When aligning backward the robot is still very consistent. It does not matter the direction in which we align. What you will learn from this tutorial is what is the consistency and reliability of the robot that you could expect.
