What is allowed and what is not when building without instructions.

This is how to use the display block to show images with the EV3 software.

Let's make a program that moves the robot forward and then backward.

Explanation and demonstration of the big task for the lesson.

There are some things to be careful about when your students work with the brick.

This is a teacher's note about the math behind calculating gear ratios with for our lifting attachment. It math model we build in previous tutorials is not exactly correct and here is the explanation why.

Each palette contains programming blocks that share common purpose. We will cover most of them

A note why we give the challenge at the start of the lesson.

The important task before the solution. If you haven't done it already, then attach a new axle at the front of the robot and extend the construction with gear wheels and axles to reach the two legs at the two sides of the robot. 

In this course, you will learn how to program the game "Keep 'em clean". This is a game where the player controls a number of "people" on the screen using movements detected by a camera.

Robots could do chores for us and they must consider the load of the cargo or the robot could be damaged.

We encourage you to explore the software on your own.

Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot. 

Let's make a competition - there is a pole that the robot must turn around and return home.

Our next robot is called CastorBot, because of the castor ball.

The task in this tutorial is to execute the program 10 times and to do it yourself. If you have your attachment then use it. If you have our attachment then use it. But execute the program 10 times and make sure that it works. 

Sometimes a good teacher needs a few tricks in his sleeve, so that he can surprise and entertain his students.

We will take a look at the EV3 motors and will go into details about them

Let's put everything that we have learned so far into practice. Let's make a spy robot!

We will demonstrate with a robot what the acceleration is and the effects of high and low acceleration.

Let us do a quick recap of the whole lifting mission and its solution

Why we will never use seconds in our lessons.

In this lesson we will program our robot to display emotions!

Every turn is a circular motion and we will review the three types of turns from this point of view.

If you've done the calculation following the previous tutorials you would arrive at a result of 18.75 rotations. But this is not the correct answer. The calculation is wrong, because the math model that we've built, although kind of obvious, is not correct. When experimenting the correct number of rotations would be 37.5. This is a large difference. Two times larger. Exactly two times large. Something should be happening here - and this thing is "planetary mechanism"

Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?
