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 video tutorial, we demonstrate an attachment that is activated when we reach the mission model. That means the attachment is not activated by a motor but by the movement of the robot. We accomplish the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model, where we have to move and bring cargo to the mission model and leave the cargo there.

In this video tutorial with LEGO SPIKE Prime we accomplish M02 Oil Platform from the FIRST LEGO League 2022-2023 SUPER POWERED robotics competition. We use the Kriket box robot and an attachment that allows us to lift. The actions of the mission is between Lift and Push, be because it is vertical.. we choose Lift. Checkout the full tutorial for all the 3 missions in a single run.

This video tutorials shows how we accomplish a specific mission model from FIRST LEGO League 2022-2023 SUPER POWERED robotics competition. The mission is called - M11 Hydroelectic Dam and in the tutorial we accomplish part of it. In other tutorials when we get back with the SPIKE Kriket box robot we have more time to accomplish the rest of the missions.

This is a programming video tutorials. It uses LEGO Education Word Blocks which is the scratch version. We enter into details of how to accomplish missions in a tight spot, how to align the robot and how to make it repeatable.

This 10 out of 10 tutorials is about consistency and reliability of the robot when accomplishing 5 missions in a row. We explore how we move between mission models. The programming is in the previous tutorial, here we look and discuss the behaviour of the robot

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.

This is a 10 out of 10 tutorial for a complex robot attachment that does a precise drop and is auto-correcting at the same time. It has decent consistency and reliability. We drop cargo onto the train and use a LEGO Education SPIKE Prime robot for this FIRST LEGO League 2021-2022 competition.

This is a precise drop tutorial where we demonstrate how to accomplish the FIRST LEGO League 2021-2022 Load Cargo mission that requires us to precisely drop a cargo into the drain. It is not an easy task, but it has a trick. A trick that allows us to 'shake' the cargo a little bit. The attachment is also auto-correcting to improve consistency. Use this principle whenever you need to drop things.

This is a 10 out of 10 tutorial on a basic approach for one of the unique challenges in FIRST LEGO League competitions. This basic approach to a solution is not very consistent, and in some of the next tutorials, we will present a new solution. But we decided to record it to demonstrate how reliable this attachment is when it comes to carrying large objects. That could give you ideas of things to avoid.

In this video tutorial, we demonstrate one of the unique missions of the FIRST LEGO League competitions - we must carry a rather large object from base an leave it on the field. This takes some considerations as other missions must be accomplished before that.

This is a 10 out of 10 tutorial, where we demonstrate the consistency and reliability of an attachment activated when we reach the mission model. We do not use a motor. We activate the attachment by pushing the robot to the mission model of the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery Mission.

In this video tutorial, we demonstrate a configurable attachment used for accomplishing a FIRST LEGO League 2021-2022 Cargo Connect mission called Sorting Center. The mission model has three cargo objects that are placed randomly. The attachment is configured before the run based on the configuration of the cargo objects. This attachment is also very powerful as it aligns and auto-corrects the errors that the robot is making by squaring the robot.

You think that you can quickly change the attachments of your LEGO Mindstorms EV3 competition robot? Are you sure? In this first episode of the series you will see how to create and attach attachments without using pins and how faster and easier this could be. You will see the design logic of a few attachments and how they work on the field. 

"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 use the motion sensor and demonstrate 10 out of 10 times how we can keep the robot moving in a straight line. The program is described in the previous tutorial in the lesson where we enter into the programming. Here we visualize how consistent and reliable the behavior of the robot is.

Pinless attachments are smart and quick and could make a big differences between two robot constructions. In this video we are sharing a nice idea for a pinless attachment placed below the robot.

If you think that the quick pinless attachments shown in video 63 are quick enough, see this tutorial and you will find out that the quick pinless attachments could be even quicker. These attachments can work without motors but by using the inertia forces.

This is a 10 out of 10 tutorial, demonstrating the consistency and reliability of the active attachment for switching the engine in this mission. The power is transferred through a system of gear wheels to a lever at the end. We presume that the robot is already positioned.

This video tutorial demonstrates an attachment that flips a mission model. The mission model is attached to the field, but it contains a lever. This lever must be flipped from one side to the other. There is a switch. We use a pinless active attachment with gear wheels, and you can see how this works in the tutorial. There is no use of sensors as we don't need them. We will leave the alignment and positioning for some other tutorials.

One attachment to rule them all...We have seen it and it works -> solving most of the competition models with only one attachment. In this video tutorial without programming we would walk you through the principles and methods of using a single attachment for most of the FIRST LEGO League competition models. One can learn alot from using as few parts as possible to solve as many missions as possible.

The video shows why you should not build attachments such as "Crappy Active Attachment For SUV Box Robot". In the video one can see how the knob gear wheels start "jumping", once a force is applied to the lever. 

This is an animation of a quick pinless attachment that is placed below the robot and is used to deliver parts, like the Container Mission model, to different parts of the field. In the live video in the lesson we explain more about the principles, while here in the animation you can get a quick overview of how it works and you can try to follow the same principles for an exercise.

In this video tutorial we demonstrate the user of a quick 'pinless' attachment. As all pinless attachment it is not that they are completely pinless, but that they do not require the "click" of the pins that is often difficult to achieve in a quick pace environment as during FIRST LEGO League competition rounds.

In this video tutorial we continue the exploration of pinless attachments and how to add them and remove them in a quick fashion. We've done this for SPIKE Prime and for EV3 and we will provide some other references in the lesson in the course. The idea of an attachment below the robot is that sometime, during FIRST LEGO League competitions we have to bring a mission model from one place of the field to other. Basically push it.

With this animation we demonstrate an example for a quick pinless attachment that could be used to collect loops. Loops is one of the most common missions at FIRST LEGO League competitions. We use the LEGO Mindstorms Robot Inventor set to build the attachment, the mission model and the robot. They are all from the same attachment. In the live video in the same lesson we enter into more details about the attachment and we describe its idea
