When aligning backward the robot is still very consistent. It does not matter the direction in which we align. What you will learn from this tutorial is what is the consistency and reliability of the robot that you could expect.
In this video tutorial we follow a line 10 consecutive times. In this way we demonstrate whats the consistency that you could expect from the robot when following a line with a multi-states algorithm.
In this video tutorial we demonstrate a few ways to use the Distance sensor from the LEGO Mindstorms Robot Inventor on FIRST LEGO League competitions. We don't enter into the details about programming as we do in the LEGO Mindstorms Robot Inventor Programming course, because here we demonstrate the behavior of the robot when the sensor is use and we make the argument that you should always use sensors at FIRST LEGO League competitions
We are ready to build the first program for moving the robot forward and backward. We learn how to build simple programs for moving the program. But it is not that easy...downloading to the robot does not always result in the robot moving.
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.
Without the use of the sensors, make sure that you are at least using "set movement acceleration to slow". In this tutorial we will demonstrate why and how this helps us improve the accuracy and consistency of the robot.
We would start connecting a lot of things to the Raspberry Pi. It will be good if we could have some way of referring to the pins on the Raspberry Pi. For example like Pin 5 or Pin 26. Luckily there is such a way.
Why we change the robots all the time and what to observe in each new robot.
To prepare the robot to move in a square and to use a loop in the program we would first make this VEX EDR robot move forward and turn, using a program developed with RobotC.
Spinning with the VEX EDR robot involves the use of both motors. The left and the right. Every robot with wheels could spin and this makes not exceptions.
To control the VEX Cortex controller we must use a software. In this episode we would download the software from the VEX site. Strange thing is that you must select your region correctly even if you are not in this region
In this video tutorial, we demonstrate a reusable attachment. It is the same attachment we've previously used for two other missions. Sometimes we can build such attachments - one attachment that can complete several missions. Yes, the mission is similar - it is Load Cargo, but we are loading the cargo in different places on the field, and that's important.
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.
How to keep the discipline in the classroom and how to cheer up the students.
The next important step when turning with a robot is to learn how to do an Arc turn.
In this tutorial we demonstrate how accurate the robot is when we are moving it slow vs when moving it fast. The point of the tutorial is to show that moving slowly is generally much more accurate. It is not accurate enough for a FIRST LEGO League competition, but if you have to move without the use of the sensors you can at least move slow.
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.
Where is the math while turning? Is there any math involved? Should there be?
In this video tutorial we accomplish a robotics competition mission model and we accomplish it 10 out of 10 times. The mission is Pull-up from the FIRST LEGO League 2020 RePLAY competition. The goal of the mission is to pull up the robot on the bar. The robot must not be touching the ground.
In this LEGO robotics video tutorial we will accomplish mission 8 from the FIRST LEGO League 2020 RePlay competition. The name of the mission is Boccia. What you will learn from the video is how to accomplish complex missions that require following a line, aligning to the line and accomplishing many mission models in a single run
We need to extend the cables to be able to connect them to our Raspberry PI. We must also add new connectors at the end of the cables.
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.
We challenge you before we give you the theory: browse in the software and try to achieve the behavior in the video below.
How does this construction of VEX EDR turn? It has two motors. Let's start with turning right
In this part 2 of the LEGO video tutorial we accomplish the pull part of the M03 Energy storage from FIRST LEGO League 2022-2023 SUPER POWERED. Part 1 was about precise dropping, part 2 is about pulling as the model requires it
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.
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.
