Video tutorials

In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.

This is a video tutorial on accomplishing M12 and M13 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge. We've decided to combine the two missions and approach M12 in a slightly different way - by activating a gear wheel and thus rotate the chicken. The mission is accomplished in almost no time and the result is flawless. The robot is Chain Monster, a powerful LEGO Education SPIKE Prime robot.

In Episode 58 we introduced you to a LEGO Mindstorms EV3 Modular robot. In this tutorial, we show you how we reached that construction. We start from a construction found on the Internet and take you through the process of examining and improving it, till we reach a more stable and reliable robot.

This is a video tutorial that demonstrates how to accomplish M06 and M07 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster box robot which is a LEGO Education SPIKE Prime robot equipped with an active attachment with gear wheels, which engage the mission model’s gears to rotate the respective parts. The entire run takes less than 3 seconds, delivering a neat and precise performance.

In this course, you will work with other students in the group. These might be your classmates, teammates, or students you know from other activities. It is important to know your group so that you can work together with them in the best possible way.

This video tutorial focuses on M01, M02, and M14 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge. The Chain Monster box robot (a LEGO Education SPIKE Prime robot) uses a single attachment to accomplish all three missions in sequence. First, it pushes the mission model, then presses down the next one, and finally collects some mini-figures.

Second active pinless attachment for the robot construction. It is placed in the top/right corner of the robot and includes an interesting gear system for transferring the power. The attachment is suitable for complete rotations.

In this video tutorial we demonstrate how to accomplish M09 of FIRST LEGO League 2023-2024 MASTERPIECE Challenge. The robot is Chain Monster - a LEGO Education SPIKE Prime robot. It pulls the mission model and precisely positions it in the designated area. An interesting aspect is that the robot must rotate to position the loop correctly, so pay close attention when programming it.

This is a third example for adding an active attachment. This third attachment is now connected to the wheel at the front of the robot. Again, the attachment could be easily extended. 

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.

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.

In this video tutorial we focus on accomplishing a part of M08 of FIRST LEGO League 2023-2024 MASTERPIECE season. The mission is to lift and unlock the lever to make room for rolling the camera. It's a simple action but requires the robot to be stable and accurate. We use the Chain Monster - a powerful LEGO Education SPIKE Prime robot.

In Episode 58 we introduced you to an LEGO Mindstorms EV3 Modular robot. Mic Lowne wrote to us and had that robot remade, because it used too many blue lego pins and could not be build using one EV3 kit.

In this video tutorial, we are accomplishing three missions in a single run from the FIRST LEGO League MASTERPIECE season. We are using our new out-of-box LEGO Education SPIKE Prime robot, called Kufar. Have you used such robots? No? Well, let's dive deeper in the construction of out-of-box robots and see how convenient and user-friendly they can be. Take one brick with a couple of sensors and let your imagination run wild as you create the most inventive attachments.

The last fifth construction is larger compared to the previous constructions. It is wider. It has four sensors and you can take a larger load all by keeping the robot stable. 

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.

Need to transfer circular into a linear motion. You need a rack. Here is an attachment with a rack for our box robot.

This M12 Water reservoir from FIRST LEGO League 2022-2023 is accomplish in two part with the Chain Monster box robot. The first part is in a previous tutorial. This is the second part where we collect the third water unit. We use a passive attachment to collect this unit.

This is a very interesting idea that is worth sharing with the rest of the teams and the ELM team has provided it to us. Check out how they drop a LEGO human at a specific place.

In this video tutorial we accomplish the FIRST LEGO League 2022-2023 SUPER POWERED mission called M04 Solar Farm. We use the chain monster box robot along with a passive attachment that helps us collect 3 of the energy units. The interesting thing about the mission is the collection of the units, of course, but also the way this robot manoeuvres when there is not enough space. It aligns to the lines, it uses the color and motion sensors. Really advance way to align the robot.

In this video tutorial the Chain Monster LEGO box robot uses a multi-purpose attachment to collect two elements from the FIRST LEGO League 2022-2023 SUPER POWERED field and these are the "water" units on the field. What's interesting is that the contain where the water units are stored could be closed and opened and this allows us to freely move while non of the water units are lost.

Based on feedback from many of you in this episode I would like to show you how to build an active attachment that changes the orientation of a gear wheel placed vertically to a gear wheel placed horizontally. This attachment could be used in competitions and shows a basic principle of changing the orientation. All attachments could follow the same principle. 

The attachment builds on previous episodes this time using two LEGO rubber bands. When a lever is released the rubber band exerts pressure on it and moves it in a circular motion. As an example we are solving the 2012 FIRST LEGO League, Senior Solutions, stove mission (which was quite interesting as a mission)

In this video tutorial we pull the Smart grid mission model from the FIRST LEGO League 2022-2023 competition. The goal is to lift the hand to connect with the hand on the other team field. We do this my pulling on the attachment and we reuse the same "hand" that we have for collecting.

Each year the FIRST LEGO League robotics Competition involves loops. In this video tutorial I will go through the most common way of taking loops, show its disadvantages and suggest another way to do it.

In this video tutorial the Chain Monster box robot accomplishes a mission that requires two actions. We should lift up (lever) and push almost at the same time on the mission model for it to release the batteries. These mission model is from the FIRST LEGO League 2022-2023 SUPER POWERED competition.

This is one of the very interesting attachments by the ELM team. It is using rubber bands and some rubber to precisely drop the chicken. Very interesting way. Check it out and try to learn from it.
