Video tutorials

In this episode we combine in a single program the previous two programs for moving forward and backward. 

The scorpion is one of the most famous robots build with the NXT kit. In this lesson we are showing how to use the rotation sensor to program the scorpion and its strikes. The main challenge is how to return the spike for the same amount of degrees after it strikes. The other topic is how to use variable to keep the state of the scorpion. Both of this techniques are very valuable during the competition.

This is the first part of accomplishing M03 Energy Storage with the Kriket Box Robot. In this tutorial we show how to Drop the energy units in the storage. The second part will focus more on how do we pull the element from below the energy storage.

In the course, we are going to use the following components and hardware elements. It is important to know their names and what are they used for.

In this 10 out of 10 tutorials we do 10 runs that demonstrated how consistent and reliable it is to stop at the second intersection. This is useful as it is one of the main ways to figure out how to position yourself on the field.

When aligning backward the robot is still very consistent. It does not matter the direction in which we align. What you will learn from this tutorial is what is the consistency and reliability of the robot that you could expect.

In this video tutorial we follow a line 10 consecutive times. In this way we demonstrate whats the consistency that you could expect from the robot when following a line with a multi-states algorithm.

In this video tutorial we demonstrate the user of a quick 'pinless' attachment. As all pinless attachment it is not that they are completely pinless, but that they do not require the "click" of the pins that is often difficult to achieve in a quick pace environment as during FIRST LEGO League competition rounds.

We are ready to build the first program for moving the robot forward and backward. We learn how to build simple programs for moving the program. But it is not that easy...downloading to the robot does not always result in the robot moving. 

In this tutorial we demonstrate how accurate the robot is when we are moving it slow vs when moving it fast. The point of the tutorial is to show that moving slowly is generally much more accurate. It is not accurate enough for a FIRST LEGO League competition, but if you have to move without the use of the sensors you can at least move slow.

Without the use of the sensors, make sure that you are at least using "set movement acceleration to slow". In this tutorial we will demonstrate why and how this helps us improve the accuracy and consistency of the robot.

We would start connecting a lot of things to the Raspberry Pi. It will be good if we could have some way of referring to the pins on the Raspberry Pi. For example like Pin 5 or Pin 26. Luckily there is such a way. 

Why we change the robots all the time and what to observe in each new robot.

To prepare the robot to move in a square and to use a loop in the program we would first make this VEX EDR robot move forward and turn, using a program developed with RobotC.

Spinning with the VEX EDR robot involves the use of both motors. The left and the right. Every robot with wheels could spin and this makes not exceptions.

To control the VEX Cortex controller we must use a software. In this episode we would download the software from the VEX site. Strange thing is that you must select your region correctly even if you are not in this region

In this video tutorial, we demonstrate a reusable attachment. It is the same attachment we've previously used for two other missions. Sometimes we can build such attachments - one attachment that can complete several missions. Yes, the mission is similar - it is Load Cargo, but we are loading the cargo in different places on the field, and that's important.

The next important step when turning with a robot is to learn how to do an Arc turn.

In this video tutorial, we focus on accomplishing M04, M14, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the MiniBox, a LEGO Education SPIKE Prime box robot equipped with several attachments. The goal of the robot is to deliver the LEGO mini figures to their designated place and then press down the M03 platform to trigger the immersive experience for the viewer in the mission model.

In this part 2 of the LEGO video tutorial we accomplish the pull part of the M03 Energy storage from FIRST LEGO League 2022-2023 SUPER POWERED. Part 1 was about precise dropping, part 2 is about pulling as the model requires it

This is an animation of a quick pinless attachment that is placed below the robot and is used to deliver parts, like the Container Mission model, to different parts of the field. In the live video in the lesson we explain more about the principles, while here in the animation you can get a quick overview of how it works and you can try to follow the same principles for an exercise.

Where is the math while turning? Is there any math involved? Should there be?

In this video tutorial we accomplish a robotics competition mission model and we accomplish it 10 out of 10 times. The mission is Pull-up from the FIRST LEGO League 2020 RePLAY competition. The goal of the mission is to pull up the robot on the bar. The robot must not be touching the ground.

In this LEGO robotics video tutorial we will accomplish mission 8 from the FIRST LEGO League 2020 RePlay competition. The name of the mission is Boccia. What you will learn from the video is how to accomplish complex missions that require following a line, aligning to the line and accomplishing many mission models in a single run

We need to extend the cables to be able to connect them to our Raspberry PI. We must also add new connectors at the end of the cables.

Following the principles from the previous video, try to make the attachment that you've built, more stable and durable.
