Video tutorials

In this video tutorial, the Chain Monster box robot accomplishes three missions in a single run from the FIRST LEGO League 2023-2024 MASTERPIECE Challenge season. The LEGO Education SPIKE Prime robot uses an active attachment to collect the mini figures, to push a lever, and to deliver the figures to their designated places. The robot starts from the red base and returns to the blue base, performing all these actions in less than 20 seconds - consistently and reliably.

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M05. EXTRACTION, but compared to one of the other tutorials about this mission, in this specific tutorial we are using Box Robot 1 and a multi-purpose attachment. The attachment is designed for two missions and one of the missions is the Extraction

In the RobotC software we could make the robot wait for a couple of seconds by using the wait function. This will give the motors a chance to work and this will actually move the robot. 

This animation demonstrates the use of a Grab Attachment build from LEGO Mindstorms Robot Inventor 51515 set. Many of the FIRST LEGO League missions could be accomplished by grabbing the mission model and the principles shown here is useful for mission models that look like a loop

How important is it to have predictable behavior in your classes.

This is a 10 out of 10 video tutorial demonstrating the consistency and reliability of the Kriket robot when accomplishing the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery.

This is a 10 out of 10 tutorial that demonstrates the consistency and reliability of the robot to complete the Unused capacity mission. In this mission, we do not need any guidance to push the model as it is near the west side where it should arrive.

Parents generally use the same email address for their students. When enrolling into a group it is possible to enroll another user for the same email address. We call this a "brother or sister". Brothers and sisters could share the same email address but they have two different usernames. 

The process of registering a brother or sister is the following

The topic of this tutorial is the purpose of a system of gears when throwing a ball.

The length of the lever has a certain effect when hitting the ball. In this tutorial, I would like to discuss what it's the effect. 

How to control the speed of the motors and the speed of the robot.

In this tutorial, I will cover the adjustments of the display and the color lamp blocks from the LEGO Mindstorms NXT-G. Today I will show you how to use the color lamp in order to make your robot more interesting or how to display sensors values or try to draw something on the screen of the brick.

In this LEGO video tutorial we accomplish 3 missions with the Kriket box robot. A number of actions are performed like Lever, Lift, Drop, Pull, Align. This tutorials shows how to accomplish missions models that are closely positioned next to each other.

This is a 10 out of 10 tutorial where we deliver and drop precisely to complete a FIRST LEGO League 2021-2022 Cargo Connect mission. We reuse the same attachment as in other missions to demonstrate a reusable attachment.

The dance mission is one of the most straightforward and easy missions to complete at the FIRST LEGO League competitions. This one is from RePLAY competition. The goal is to reach a specific place on the field and dance with the robot. You will see how we dance and have fun with our robot. Never forget to have fun during the competitions.

This is a 10 out of 10 video tutorial for the Slide mission at the FIRST LEGO League 2020 RePlay LEGO robotics competition. In the tutorial we demonstrate how to accomplish the mission 10 out of 10 times. At FLLCasts we try to build the attachments to be as consistent in their behavior as possible possible. In this way you know how the attachment along with the LEGO Education SPIKE Prime or LEGO Mindstorms robot will behave.

We are about to connect the whole car with the lights and motors to the controller. Let's recap to know what is ahead of us, what would the process be and what is the end result of the next couple of sections when at the end we have a car controlled by the phone

The tutorial is about what are the parts that you should buy to have the Ball Collecting mechanism. 

In this episode we combine in a single program the previous two programs for moving forward and backward. 

Energy storage mission from FIRST LEGO League 2022-2023 is again a two parts mission where we have to drop a few energy units in the mission model, but we also have to pull part of the mission model. In this video tutorial we demonstrate how the Chain Monster LEGO box robot accomplishes this with a multi purpose attachment for box robots.

"Sometimes it works, sometimes it does not work" - this is the most common case in FIRST LEGO League competitions. In this tutorial, we demonstrate and discuss such a case where the first part of accomplishing the mission always works but the second part has about 60-70% success rate. The robot is not very consistent. Let's take a moment to see it and explain why so that we can resolve the problem in the next lesson.

In this video tutorial we demonstrate the behavior of a LEGO Mindstorms Robot Inventor robot when we use the Motion sensor. The Motion sensor was also referred to as Gyro sensor in previous versions of the LEGO Mindstorms Robot. We do not enter into the details of the programming and you can download the programs from the course lesson, but we make a demonstration of how the robot turns to about 95 degrees when we try to turn it to 90 degrees, we explain why and we suggest a way to improve the behavior of the robot.

In the course, we are going to use the following components and hardware elements. It is important to know their names and what are they used for.

The scorpion is one of the most famous robots build with the NXT kit. In this lesson we are showing how to use the rotation sensor to program the scorpion and its strikes. The main challenge is how to return the spike for the same amount of degrees after it strikes. The other topic is how to use variable to keep the state of the scorpion. Both of this techniques are very valuable during the competition.

This is the first part of accomplishing M03 Energy Storage with the Kriket Box Robot. In this tutorial we show how to Drop the energy units in the storage. The second part will focus more on how do we pull the element from below the energy storage.

In this 10 out of 10 tutorials we do 10 runs that demonstrated how consistent and reliable it is to stop at the second intersection. This is useful as it is one of the main ways to figure out how to position yourself on the field.
