How does this construction of VEX EDR turn? It has two motors. Let's start with turning right
This is a 10 out of 10 video tutorial demonstrating the consistency and reliability of a configurable attachment. The attachment is designed to accomplish the FIRST LEGO League 2021-2022 Cargo Connect mission model called Sorting Center. The mission model has 3 cargo objects that could be placed in a different way. The attachment is configurable and before the run we configure it for the specific way in which the mission model is set up before the start of the round.
"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 a robot attachment that could be used to lift loops and other objects. Almost every year there is a mission at FIRST LEGO League competitions that involve lifting and the principle is interesting. You can build the attachment, robot and mission model from a single LEGO MINDSTORMS Robot Inventor 51515 set and learn a principle of building an attachment for lifting.
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.
This video tutorial contains a details explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M06. SPACE STATION MODULES. This again is a very interesting mission from the competition from which we could learn a lot of basic principles in the field of robotics.
We challenge you before we give you the theory: browse in the software and try to achieve the behavior in the video below.
In this tutorial, we would build a simple program for controlling the Tetrix robot motors with the GamePads. We use the stick and when the stick is pushed forward the motors move forward. When it is pushed backwards the robot moves backwards.
In the current course we would use a number of languages. Generally we would program the robots in EV3-G, but we would also program them in JavaScript to make the parallel with the JavaScript. The programming would include arrays, switches and loops.
This is a recording of a completely perfect, 10 out of 10 accomplishment of a two-part mission - Train tracks, from the FIRST LEGO League 2021-2022 Cargo Connect competition. Due to the proper use of motion and color/light sensors, the robot is 100% consistent and reliable for a non-trivial mission. Even when the robot makes a mistake, it auto-corrects and compensates for this mistake.
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.
Give it a name and you will have power over it. I learned this from an MIT professor. So let's give the part of the car names. Then we could refer to them. Talk to them. Change them. Do all kinds of things with them. Give it a name and you will have power over it.
In the previous video, we found the correct answer for our task and it is 18.75, or is it?
Following the principles from the previous video, try to make the attachment that you've built, more stable and durable.
Как да помогнем на учениците да разработват дълги програми.
10 out of 10 is our favorite series of video tutorials and in this one we are looking at the FIRST LEGO League 2021 RePlay competition and the tire flip mission. The goal of the mission is to flip a tire. Two tire. Perfect. We manage to do it each and every try
In this video tutorial we accomplish the Innovation project mission from the FIRST LEGO League 2020 RePlay competition. The goal of the mission is to build a new construction on the day of the competition and to complete a mission with this new construction. There are a couple of spare parts in the FLL set and building the construction for the innovation project was quite fun.
Try to solve the challenge of this module and observe the cup.
There are number of settings in a Move block and now we will focus on the rotations setting
There are a number of tools available online to help you play the game. You just seed the initial conditions and leave the game. Let's look at some of the sites.
Find a plastic element. Cut it to 200mm by 140mm and attach this plastic plate to the front of our FIRST Technical Challenge Tetrix Robot.
We will explain inertia non-scientifically so that we make it easy to understand concept.
Display a matrix with "life" and "dead" cells on the EV3 LEGO Mindstorms brick screen. The program is available. You can see it, change it, modify it and learn from it.
In this lesson we build a simple LEGO Mindstorms NXT calculator program that sums, multiplies, subsctracts or divides two numbers between 1 and 50.
It all started with the famous 2017 mission for flipping a manhole and it was one of our favorite missions ever. Here in this tutorial we demonstrate the same principle of flipping a part from one side to the other. Sounds interesting, yes it is, yes it is.
This video tutorial shows how the LEGO Mindstorms EV3 Shotgun Motorcycle robot works. The robot is a sligh modification of the Ninja motorcycle because it has assiting wheels
