Video tutorials

Unplug one of the cables and observe what the robot does.

This video lesson shows a very interesting specific example on how to use the LEGO Mindstorms EV3 Ultrasonic Sensor. The sensor detects if the catapult is loaded or if we have just fired an element. At the end of the lesson I also offer an interesting challenge that you could use in your classroom or at home.

Let's implement a more advanced program for this robot to learn how to use with motors in opposite directions - and this is to implement the Proportional Line Following algorithm.

We would see how both satellites work together on the World Robotics Olympiad competition. They must both follow different orbits and must cooperate for the mission to be accomplished.

One of the simplest tricks in the game - move, complete the mission and leave the attachment with the mission model. You don't have to return the attachment to the base. On some competitions there might be penalties, but it might be worth it, as you save time to complete another mission. This works especially well with large attachments.. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

Now we have to program the robot. The steps that we will cover are starting the software, writing a program and downloading it to the robot.

Now that you have tried and solved a challenge involving a series of instructions, we would like to share a few best practices.

Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.

We will cover three ways to transfer your program from the computer to the robot.

When organizing this course, the behavior expectations should be set at the very beginning of the course.

Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.  

One of the students' favorite LEGO Mindstorms robots. Have fun with Iqazator, moving over all kinds of obstacles as a real millitary tank machine. 

The challenge is to make the robot move back and forth with ever decreasing distance.

In this video we are solving part of the FIRST LEGO League Senior Solutions challange missions (FLL 2012) using LEGO Mindstorms NXT robots. I make a step by step explanation of each move I make. The goal of this video is to help you with ideas and suggestions on how one should look at the missions.

In this video tutorial we would look at the mission run for M06. SPACE STATION MODULES. The missions is to precisely push a mission model into an opening. In almost any FIRST LEGO League competition there are such missions. The tutorial contains only the mission run on the field. We accomplish a single mission. 

Vision is still one of the very few fields where a human being could outsmart a computer. Still. Colour/Light sensors are the cornerstones of implementing a smart LEGO Mindstorms robot that could at least partially do "vision". In this video tutorial, we are using the robotics sensor to detect loading and unloading of the catapult.

What a teacher must look out for, while students are building a robot from instructions.

The robot works on the field and decodes the different colours that represent the rows and the columns.

We start with FIRST Technical Challenge and how you develop programs with the GamePads. It is up to you to decide how sticks, buttons and triggers from the GamePad will control the different motors of the robot and there are different decisions that you should make. 

Now we will create the first program in this course and we will make the robot move forward.

Introducing three main concepts - Energy, Inertia Moment and Angular Velocity. We describe what is the moment of Inertia, how do we calculate it and how do we measure it?

In this tutorial we will build our first 3D LEGO model using LDraw. I will build it using two different programs based on the LDraw library - MLCAD and LeoCAD.

In the first module of the perfect STEM Course we will move fast, but not deep. We would explore a number of different areas of technical science like electronics, Linux, programming, mobile technologies, AI without getting into too many details. The goal is for us to arrive at a working Remote Control car controlled from the phone and to learn basic concepts on which we could extend.

We will demonstrate how to connect the brick and the motors by using cables correctly and reliably.

After we have introduced a menu in the previous video, this video focuses on storing the values in an array. It presents a basic use of arrays.

In this episode we are showing the great similiarity between the sensors in NXT Mindstorms. We are solving a common problem - How to make a robot that do not fall from the table. We are using the Ultrasonic sensor, Light Sensor and Touch Sensor to solve the same problem, but with three different sensors.
