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.

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.

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 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?

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

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.

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

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

If you get to a solution that is too complex you should always try to improve it. This is what we are doing here. Arriving at a solution for aligning to the wall that has become too complex.

We explore some common mistakes when a program is developed and becomes complex. We then try to remove part of this complexity. 

Using the rack depends on the experience of the team. Based on this a different number of gear wheels and racks would be used.

How great is the great attachment for lifting that we built in this course? How many times can it lift the robot without making an error? How great are your attachments and how could you test them? - the answer is simple. Just try 10 times and they should work at least 9 of them as our attachment is.

A human being walks with an average speed of about 5 km/h (3 miles/h). In this video tutorial we will develop a block for LEGO MINDSTORMS EV3, that measures the speed of the robot in distance/time units where time will be configurable and could be 1 second or 0.5 seconds or any other number of seconds you pass as a param to the block. Measuring the speed of the robot is very powerful if you start building an Artificial Inteligence for your robot and is quite fun :)

"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must. 

In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block

When we, the teachers, make programs and projects, we give them descriptive names. Let's show you a way to put cool names on your programs.

It this episode we would present you with our attachment for lifting the robot. 

Let's review the LEGO Mindstorms EV3 Intelligent Brick

The EV3 brick is the main computer of your LEGO robot and it has a display, a few buttons and various ports.

Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.

Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units.
