Video tutorials

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.

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

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

Time to experiment with the controller, the diode and the program that makes the diode blink. Don't be afraid to change the program. We've prepared a number of tasks for you in the course that you should definitely complete before moving forward.

On the topic of following lines with a robot there is a way to make the robot follow the line a little more precisely. This method is called "Multi-states" program. Or at least we call it like this. In this tutorial you will see how we program 5 state for the robot line following program. This could be particularly important with FIRST LEGO League competitions where we must build consistent and reliable robots.

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.

With this first tutorial on the Motion Sensor in the LEGO MINDSTORMS Robot Inventor course we demonstrate the basic algorithm for moving in a straight line with the Motion Sensor. From here all the other algorithms are modifications, and if you know the basic it will be easier to tweak the behavior for your particular challenge

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.

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

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.

This is the 10 out of 10 version of executing 3 missions in a single run. It worked like a charm! 10 times. We push and collect energy units for the FIRST LEGO League 2022-2023 SUPERPOWERED Challenge competition.

This is a 10 out of 10 video tutorial that demonstrates the consistency and reliability of the robot that accomplishes the Unlock Cargo Plane mission. The attachment is an active attachment with gear wheels. It has a single lever constructed from 2 beans and we use this attachment to push on the mission model.

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

Is it better to do fast turns or slow turns? Should you save some time by turning fast or should you be more precise by turning slow. Where is the balance? This video tutorial demonstrates exactly this for LEGO Education SPIKE Prime robot, their motion sensor and an ever occurring question on FIRST LEGO League competition which is how to find the balance and where is the balance.

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.

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

Let's move with the VEX EDR robot using its motors, the wheels and some RobotC programming. We devide the program in three parts - Connect the motors, program the controller and turning.

In this tutorial we go through the VEX IQ Challenge. Most of the challenges are related with manipulating objects. The most common object used in competitions are balls. That is why we take a look at a simple mechanism that can be used for throwing a ball.

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.

This is a 10 out of 10 tutorial in which the MiniBox robot accomplishes the M12, M13, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. The MiniBox is a LEGO Education SPIKE Prime box robot that uses detachable attachments.

In this run, the robot performs five actions: it collects the M15 minifigure and throws it backward, rotates the chicken for M12, and then pushes and pulls the M13 Craft Creator mission model. All of these actions are completed in under 15 seconds!

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"

This is a 10 out of 10 tutorial, demonstrating the consistency and reliability of the active attachment for switching the engine in this mission. The power is transferred through a system of gear wheels to a lever at the end. We presume that the robot is already positioned.

The reason why you would want to watch this tutorial is because it demonstrates one of the most reliable ways to know where you are on the field and to accomplish missions successfully and this is aligning to a line. In the tutorial you will also see how a parallel program is developed and who parallel programs could be used in a meaningful way.

In this video tutorial we will reach a specific location on the field 10 times. This programs demonstrates the accuracy and consistency of a program that used the Motion Sensor to detect the angle at which the robot rotates. At the end of the tutorial you will have a visual and clear picture of what you could expect from this basic usage in terms of consistency and accuracy. This might be enough for some cases and it might not be enough for others.

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?
