Video tutorials

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

This video tutorial shows how the LEGO Mindstorms EV3 Handlebar Chopper Motorcycle robot works. See how fast it is.

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

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M05. EXTRACTION. On every robotics competition we have the challenge to collect, carry and return to base a number of objects. It is just in different way every time.

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

Why we will never use seconds in our lessons.

An interesting question that has arise is whether we can use the LEGO Mindstorms EV3-G Software to program the NXT brick. In this episode we will go through the blocks from the EV3-G Software and see which works with the NXT Hardware and which does not.

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M14. METEOROID DEFLECTION. The mission is a simple throw of a ball. But of course the ball should reach a specific mission model and arrive at a specific place. And that's always challenging.

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

Following the previous tutorials from the course, implement the calibration of the minimum and maximum values. 

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?

What should you as a teacher know when the students are trying to achieve a program and robot attachment that could reproduce their behaviour 9 out of 10 times. 

In this video we discuss the durability of the construction of LEGO robots and how do we make them more durable. 

One of the smartest things you could do in any software program is to extract logic in small reusable, simple, understandable units. In EV3-G these are called Blocks and we are going to extract the logic for finding a minimum and maximum for each of the sensors in a new block.

A common question is how to display arrays on the LEGO Mindstorms EV3 brick screen. Displaying values from an array is not different from any other display operation. In this tutorial, we would look at displaying two specific values. The minimum and the maximum for a specific sensor from the Advance Calibration Course Section

What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?

We will share the idea behind that challenge and how to conduct the challenge in a classroom.

Following the Advanced Sensor Calibration course section, it is time to extract the logic for getting a calibrated value into a new block. This block will have an input and on this input, we give the port number. The block will return the calibrated value for this port number. We've built all the other blocks only because of this almost final video here.

When you first start the EV3 brick, you see the recent programs menu. Let's see what it is all about.
