Video tutorials

In this tutorial, we record an example of how to cut the pipe to the desired length with a hacksaw. Cutting with a hacksaw is very common during FIRST Technical Challenge Preparation

In this tutorial, we are controlling the FTC Tetrix robot with the two sticks of the same GamePad. The left stick is for forward and backwards, while the right stick is for left and right.

How to approach that fun relief task.

How to place the cup on the robot so that the challenge is challenging.

This is a 10 out of 10 video tutorial where we demonstrate the consistency and reliability of a LEGO Education SPIKE Prime Active attachment connected to the motors of the robot. The goal of this attachment is to accomplish the Bridge mission where we have to push both parts of the bridge and bring them down to connect them. We use some line following.

This is the first, but not the last video tutorial of the course where we reach a specific mission model in a consistent way. We use the Motion sensor and only some basic principles like turning to an angle. If we use the principles in this tutorial and then build an attachment for the mission model we will have a pretty consistent way of accomplishing the FIRST LEGO League mission

This video tutorial is about how to accomplish the Rowing Machine mission in the FIRST LEGO League 2021 RePlay robotics competition. The Rowing machine mission model consists of a wheel that should be pushed or pulled and will lift two other wheels, just like a real Rowing Machine. What you will get from this tutorial is an example of how to build a robot that is very precise. The attachment is simple, but the programming is more difficult. You must first align to a line, and then to a wall and then make a precise turn with the robot to accomplish the mission with our attachment.

In this robotics tutorial, we present a solution to extending a VEX IQ attachment to handle two hex balls at a time

Attach an axle to the front of the robot. Find a similar one, or modify the FTC Tetrix robot to accommodate the new axle. 

The more advanced task is to more in a polygon. This would require calculating the degree of each of the turns and RobotC is a language in which you could implement this math calculation very easily.

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

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

In this episode I would like to show you how to enable the communication between the computer and the NXT brick, through the USB and using the leJOS project. Starting leJOS on Windows is pretty easy. But starting the samples and achieving the communication is the actual problem.

In this video tutorial, we accomplish a FIRST LEGO League mission called The Bridge. We demonstrate how to use a really simple active attachment where the goal of the mission is to push down both parts of the bridge. We do not enter into the programming and we leave it up to you as an exercise.

Step Counter mission model is one of the more interesting mission models at the FIRST LEGO League 2020 RePlay competition. There is a locking mechanism that does not allow us to just push on the mission model to accomplish it, you must push it really slow and to do this 10 out of 10 times it is challenging.

Present the details

The field in the game of life could be finite or infinite. It is interesting to see and learn how an infinite field behaves and works. 

You are currently using a "solutions and review" course and it is important to learn how to use it to prepare for competitions. The next few steps will help you.

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.

In this short animation we demonstrate how the LEGO Mindstorms Robot Inventor Distance sensors could be attached to the robot and then use to stop at distance from a wall. This wall could be the border of the field or another mission model. We need an attachment, we need a sensor and we need the robot. In the live video in the lesson we enter into more details and explanations of how the sensor is used. Programs for the distance sensor are provided in the lesson and in the LEGO Mindstorms Robot Inventor Programming course we enter into more details about how to program the distance sensor

10 out of 10 tutorials for the Slide mission was a challenge. There were a lot of glitches with different attachments that we built. At the end we have an attachment that is able to reliably pull the mini figures up, then forward,then down which.

In this video tutorial we accomplish the Boccia mission from the FIRST LEGO League 2020 RePlay competition. We use LEGO Mindstorms Robot Inventor robot. In this mission we use an attachment that does three things in the same time - align, push one lever and drop a couple of boxes in a target. It is a complex attachment and it is worth the watch.

The power in the car comes from the batteries. The batteries are in a batteries holder. About 5 of them. Two cables are connected to the batteries holder. It is very important to identify which of those cables is the plus and which is the minus.

Take the hacksaw, the drill and let's cut the pipe.
