Overview of what is going to happen in module 3

We are showing the first way we could position the motors on the robot construction. This seems to be challenging for many robot builders and that's why we are going to do it in a few different ways in the next few video tutorials from the series.

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.

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.

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.

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

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.

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

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.  

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. 

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

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.

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

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

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

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?

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. 

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.

This animation demonstrates a vertical lift attachment. This is an attachment that transfer a circular motion from the motors to a linear motion and is a very powerful concept. We demonstrate it with a LEGO MINDSTORMS Robot Inventor robot build from 51515 set. This is arguably one of the most complex attachments in this course.

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.

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.
