Video tutorials

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

This third way of positioning the LEGO Mindstorms EV3 motors on the robot seems to be the most productive with the most advantages. We have named it "correct", but we completely understand there might be other even more efficient ways to position the motors on the robot.

With this video tutorial we start the course for LEGO MINDSTORMS Robot Inventor and how to successfully program the robot for FIRST LEGO League robotics competition. It is good to have SPIKE Prime or EV3 for the competition. But if you happen to have Robot Inventor, don't be discourage. It is still possible to participate and accomplish a lot with the set.

In this tutorial we will go through a solution for three of the missions from 2012 FIRST LEGO League competition using only one attachment. By accomplishing the medicines, strength exercise and cardiovascular missions we earn 55 points. You can download the programs from the link in the Materials tab. 

Do it yourself, fix the errors in the construction of the EasyBot

In this video tutorial we demonstrate the classic algorithm for following a line with robots. It is widely used in FIRST LEGO League competition and could be applied to LEGO Education SPIKE Prime and to other robots also. The algorithm follows a line by moving to the left and to the right and trying to stay at the edge of a black line.

This is not the standard video lesson. We have always wanted to just destroy the field and see how easy it would be. We would prepare a detailed lesson in the next few months, but this was one of the first tries on completely destroying the FIRST LEGO League Seniour Solutions field.

One of the very common problems with the LEGO Mindstorms and LEGO Technic Gear wheels is then a tooth is skipped. In this video, I would like us to discuss this challenge and how do we solve it.

The challenge for this video is to program a menu that is controlled from the LEGO Mindstorms EV3 brick screen. 

How to organize the different robots and group of students when working on lifting the robot.

We will cover the names and the basic usage of the parts in our typical robot.

Answering three questions:

Why - because we believe any student and basically anybody must have a basic understanding of how electronic works. This course gives us the chance to present it and to move forward to better and smarter robots.

How - we do videos, we set tasks. You solve them.

What - we are using Arduino. Because it is popular, it is easy and we like it. 

We will demonstrate the common mistakes students make when building a robot.

In this video tutorial we would discuss the M13. OBSERVATORY mission from the FIRST LEGO League robotics competition 2018-2019 Into Orbit. This is an easy mission. You can accomplish it by pushing the level with the robot. The challenge is that there is not enough space to move with the robot around the attachment. Let's discuss how we could achieve it. 

After we take each sample, we perform calculations and these calculations could take different time. It is important to know how much time does it take to perform the calculations. In this video tutorial, we would data log the time and plot the data.

There are a few things that you should be careful about when building from instructions .

This second way of positioning the LEGO Mindstorms EV3 motors on the robot leaves more space for the Mindstorms brick and for attaching a third motor. We are experimenting and showing the advantages and disadvantages of this particular construction.

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.

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 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.

One of the simplest tricks in the game - move, complete the mission and leave the attachment with the mission model. You don't have to return the attachment to the base. On some competitions there might be penalties, but it might be worth it, as you save time to complete another mission. This works especially well with large attachments.. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

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.

This quick pinless attachment is designed for collecting parts by pushing them. It shows the principle of putting a robot of an attachment in a very fast manner. Such attachments are popular at the FIRST LEGO League competition. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

Now that you have tried and solved a challenge involving a series of instructions, we would like to share a few best practices.
