Display a matrix on the brick screen. Simple and easy. Download and run the program to see how

In the set for the Perfect Course, you have 3 different type of cables. They are called Breadboard Jumper Cables. We would need to use them to extend the default cables on the car and to connect the car components to our new controller

There are modifications that you must do on the FTC PushBot robot. Let's discuss them

By using the GamePad to control the arm with could lift it and return it back. The main problem with controlling the arm is that if you just use the motors you would hit the robot, bend the axles and breaks the gear wheels. We would use the distance sensor to make the arm move without hitting the robot.

Experiment with the software for about five minutes, before we even give you any directions.

Learn to program the Game of Life on the LEGO Mindstorms brick screen. This would require drawing on the brick screen, using blocks with switches and loops.

This animation demonstrates the principle of aligning to a line with two color sensors and a LEGO Mindstorms Robot Inventor robot. This is a useful concept for FIRST LEGO League competitions where you want to know exactly where you are on the field and to achieve consistent behavior. In the course lesson you will also find a live video tutorial where we enter into more details about aligning. We align the robot to a line by moving both sensors slowly until they both see a black line. When one of them sees the line we move only the other. At the end we return the first sensor back.

Overview of the big task that we want to achieve in this module.

This video tutorial demonstrates again the consistency of the program for aligning to a line. We run it ten time. We the robot is always coming from the left it is always arriving at the same position. When it is coming from the right it is always arriving at the same position.

Following the Advance Sensor Calibration course section, we found the min and max values detected by each sensor. Now it is time for the real deal of the calibration. Detect the current value from the sensor and find what is the percentage of this value for the range between min and max. 

How to add a plastic plate to the FIRST Technical Challenge Robot build with Tetrix. The plastic plate is for collecting the balls. The plate should rotate and should be connected to the axle.

With the last few videos, we entered the math world. Why we do it and what to keep in mind

With this video tutorial we demonstration the consistency and reliability of the using an intersection to position on the field. We move forward and we stop at the first intersection. We detect the intersection with a sensor. In the whole 10 runs there isn't a single mistake and you can see the precision of the robot on each run. Check it out and experiment with the same program for your robot.

This LEGO robotics video tutorial is a 10 out of 10 run of the one of the most complex missions at the FIRST LEGO League 2021 RePlay competition. As the mission has three parts we are measuring the success rate of each part of the mission. What you can learn from this tutorial is how to achieve three missions in a single run including line following and a lot of aligning

What is a single, and what is two degrees of freedom

How to construct an axle with a plastic plate connected to this axle and make this plate rotate and collect balls.

Let's cover the break at end option and learn why there is no lesson about it to students.

The previous tutorial showed you how to copy/paste instructions in RobotC. The current video will introduce you to loops. 

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.

In this video tutorial we demonstrate how the robot could accomplish the Power Switch mission. Power Switch consists of a cube with a lever and the lever should be rotate to 180 degrees. This mission model was very close to a FIRST LEGO League 2012 competition mission which was called - Oven. The robot, the attachment adn the mission model are built form a single LEGO Mindstorms Robot Inventor 51515 set and with the tutorial you will learn how to use an active attachment with 2 gear wheels to complete such missions.

This robotics video tutorial is about the FIRST LEGO League 2020 RePlay competition and how we accomplish the Slide mission with a LEGO Education SPIKE Prime robot. The goal of the Slide mission is to collect two LEGO Mini figures and bring them back to base. We are demonstrating a simple attachment that collects 2 figures placed in an add way. The whole attachment must bring one of the figures up and then back.

We've just plugged in the power bank in the Raspberry Pi controller. Has it started? Is it doing something? Why is it not moving? Simply put the raspberry power a small red diode and it just emits light. Well, it's on, but it will do nothing else.

In this robotics tutorial, we would discuss the length of the pipe and its dimensions. These are general considerations for every container on a FIRST Technical Challenge competition. 

The code is already ready. It is attached below the video. Let's see how the program works and what it does and how to use it. 

In this video tutorial we accomplish the Unused Capacity mission by pushing the mission model outside of the field in the area where we are allowed to touch the robot. We deliver the mission model to the side of the field. Before delivering, we must of course reach it and that's not always easy.
