How to add a plastic plate to the FIRST Technical Challenge Robot build with Tetrix. The plastic plate is for collecting the balls. The plate should rotate and should be connected to the axle.

With the last few videos, we entered the math world. Why we do it and what to keep in mind

With this video tutorial we demonstration the consistency and reliability of the using an intersection to position on the field. We move forward and we stop at the first intersection. We detect the intersection with a sensor. In the whole 10 runs there isn't a single mistake and you can see the precision of the robot on each run. Check it out and experiment with the same program for your robot.

In this video tutorial we demonstrate how the robot could accomplish the Power Switch mission. Power Switch consists of a cube with a lever and the lever should be rotate to 180 degrees. This mission model was very close to a FIRST LEGO League 2012 competition mission which was called - Oven. The robot, the attachment adn the mission model are built form a single LEGO Mindstorms Robot Inventor 51515 set and with the tutorial you will learn how to use an active attachment with 2 gear wheels to complete such missions.

In this LEGO robotics video tutorial we accomplish Weight Machine mission from the FIRST LEGO League 2021 RePlay robotics competition. The goal of the competition is to lift a weight. The mission model resembles a weight machine, and is actually a lever. There are three different levels and you earn different points depending on the level. The attachment for this mission model uses rubber bands and lifts the mission model.

What is a single, and what is two degrees of freedom

This is a video tutorial where we focus on M14 and M15 of FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. Here, we demonstrate the precision of the attachment. Try to build the attachment and accomplish the missions.

This is a 10 out of 10 tutorial for a 3 missions run. The robot goes out of base and accomplishes 3 missions in a single run. It demonstrates the consistency and reliability of the robot and its program that uses sensors.

This is a 10 out of 10 tutorial, where we demonstrate the consistency and reliability of an attachment activated when we reach the mission model. We do not use a motor. We activate the attachment by pushing the robot to the mission model of the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery Mission.

This FIRST LEGO League robotics video tutorial is about the Treadmill mission and how it could be accomplished. The mission is from FLL 2020 RePlay competition. Almost every year there is a mission of this type where the robot must spend a lot of time with the mission model in order to turn or lift something. These are quite interesting and challenging missions.

The Cell Phone mission is part of the FIRST LEGO League 2020 RePlay competition. The goal of the mission is to flip the Cell Phone. In this video tutorial we use a LEGO Education SPIKE Prime robot to flip the cell phone. This mission is similar to the FLL 2017: How to accomplish Manhole Cover (08th) Mission in FIRST LEGO League 2017-2018.

This robotics video tutorial is about the FIRST LEGO League 2020 RePlay competition and how we accomplish the Slide mission with a LEGO Education SPIKE Prime robot. The goal of the Slide mission is to collect two LEGO Mini figures and bring them back to base. We are demonstrating a simple attachment that collects 2 figures placed in an add way. The whole attachment must bring one of the figures up and then back.

We've just plugged in the power bank in the Raspberry Pi controller. Has it started? Is it doing something? Why is it not moving? Simply put the raspberry power a small red diode and it just emits light. Well, it's on, but it will do nothing else.

In this robotics tutorial, we would discuss the length of the pipe and its dimensions. These are general considerations for every container on a FIRST Technical Challenge competition. 

How to construct an axle with a plastic plate connected to this axle and make this plate rotate and collect balls.

Let's cover the break at end option and learn why there is no lesson about it to students.

The previous tutorial showed you how to copy/paste instructions in RobotC. The current video will introduce you to loops. 

The code is already ready. It is attached below the video. Let's see how the program works and what it does and how to use it. 

In this video tutorial, we demonstrate how to gently push an object to accomplish the mission. "Gently" means that we are pushing but not with force. If we push using force, the mission model will fall, and we will not accomplish the mission. We use LEGO Education SPIKE Prime and the Ultrasonic Sensor.

In this video tutorial we accomplish the Unused Capacity mission by pushing the mission model outside of the field in the area where we are allowed to touch the robot. We deliver the mission model to the side of the field. Before delivering, we must of course reach it and that's not always easy.

This short animation demonstrates a really useful principle for FIRST LEGO League competition and this is how to use the Inertia of the robot to trigger an attachment that will do the work for us. It is very useful as we don't have to use the motors of the robot and we can afford to use the motors for other things.

In this video tutorial, we demonstrate how Kufar accomplishes M03, M15, M11, and M04 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge season. Kufar is our LEGO Education SPIKE Prime out-of-box robot that uses a color sensor to detect the attachment frame and the respective program.

In this run, Kufar executes several complex moves while navigating the mat. At the front, the robot features a scissor-like attachment triggered by rubber bands. At the back, there is a mechanism that carries a couple of mini-figures and the M04 art piece. Carefully study the attachment, and don't hesitate to upgrade it if you like!

In this video tutorial we accomplish the FIRST LEGO League 2022-2023 SUPER POWERED mission called M04 Solar Farm. We use the chain monster box robot along with a passive attachment that helps us collect 3 of the energy units. The interesting thing about the mission is the collection of the units, of course, but also the way this robot manoeuvres when there is not enough space. It aligns to the lines, it uses the color and motion sensors. Really advance way to align the robot.

In this video tutorial we pull the Smart grid mission model from the FIRST LEGO League 2022-2023 competition. The goal is to lift the hand to connect with the hand on the other team field. We do this my pulling on the attachment and we reuse the same "hand" that we have for collecting.

In this video tutorial, we demonstrate the accomplishment of three missions in a single run. The competition is FIRST LEGO League 2022/2023 SUPERPOWERED and the missions involve carrying and delivering a dinosaur toy, delivering energy units, and delivering the innovation project model.
