Video tutorials

As an exercise try to implement the calibration of the minimum and maximum values for a single sensor. 

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

Implement the program for array initialization.

Follow the video tutorials for initializing arrays and implement the program. 

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

This videos tutorials demonstrated the robot accuracy in 10 runs one after the other. 5 of them are with the robot moving slow and 5 are with the robot moving fast. See for your self what is the accuracy achieved only with the move blocks of the robot.

This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.

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

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 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. 

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

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.

In this tutorial, we connect the Motorola phones to the Tetrix controller using the USB hub.

Why we will never use seconds in our lessons.

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

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 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.

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.

For the current specific example we need two parts - the diode and the controller. In this episode we would show you which part is the controller, which are the jumpers and finally we would choose a diode.

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

In this video tutorial we explore acceleration and deceleration and how to make the robot turn precisely by using acceleration and deceleration. The goal is for us to demonstrate a program that turns the robot to 90 degree. In the first 45 the robot is accelerating and in the second 45 it is decelerating.

As a result from the previous two videos we have a diode that is blinking. What will now happen with the diode if we remove the power and change the position of the legs.

In this video tutorial we start with the basic of the basic, eg. how to move. We use the block from LEGO Education SPIKE Prime Word Blocks software. It is based on Scratch. The goal of the tutorial is to demonstrate how we can move and to teach something very important - the robot moves inaccurately

An advanced but understandable description of how to program the mindstorm robot to move in a regular n-gon like pentagon, hexagon etc. (Yes, we know math). We have also included notes on the used formulas. A must see for each of you who would like to master the robot movements.

One of the easiest ways to improve the accuracy of LEGO Education SPIKE Prime robots is to use acceleration and deceleration when moving. This also applies to LEGO Mindstorms EV3 and LEGO Mindstorms Robot Inventor and generally to most robots that we know of. This tutorial demonstrates how acceleration and deceleration could be used and what improvement in accuracy and consistency you could expect. This is quite useful for FIRST LEGO League and other robotics competitions.

In this video tutorial we try to move forward with a LEGO Mindstorms Robot Inventor robot and we try to keep a straight line using the Motion Sensor. Without entering into the details of the programming we demonstrate what is the behavior of the robot when trying to keep a straight line with the Motion Sensor while we are participating in a FIRST LEGO League competition.

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.
