• Lever

This one is very special- an attachment that could lock itself on purpose while working. 

Enchansing a previous attachment, but only this time we are solving the FIRST LEGO League 2012 Medicine mission. There is a lever and a rubber band. When the lever is released the rubber band activates the attachment. 

We just had some enormous amount of fun with building and using a catapult/trebuchet. Yes they are quite different, but the result achieved in the lesson is something in the middle. Learn how to fire elements using the LEGO Mindstorms EV3 or NXT robotics set. Challange yourself, your team or your students to build it and fire elements as far and as accurate as possible.

Part four of the Catapult series is again about loading the catapult automatically but this time using EV3 brick, motor and sensor. We use a gear system with a medium complexity along with a "standard clutch" available in the LEGO Mindstorms EV3 kits. As a result, at the end of the video, the Catapult loads and fires automatically.

We call active attachments those that are powered with a motor. This one is in the the mission of lifting levers which is common at robotics competitions like FIRST LEGO League/World Robotics Olympiad. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

In this second video lesson on catapults we improve the stability of the base of the robot. An important feature of the new base is that it is not bending. Use the same principle in all of your constructions to achieve better, stronger robots.

Part three of the Catapult series is about loading the catapult automatically. We use a gear system with a medium complexity along with a very interesting "clutch" developed with parts entirely from the LEGO Mindstorms NXT kits. As a result, at the end of the video, the Catapult automatically loads and fires.

In this video we are solving part of the FIRST LEGO League Senior Solutions challange missions (FLL 2012) using LEGO Mindstorms NXT robots. I make a step by step explanation of each move I make. The goal of this video is to help you with ideas and suggestions on how one should look at the missions.

This animation demonstrate the use of an LEGO MINDSTORMS Robot Inventor attachment to lift a lever of a mission model. The mission model is the Power Switch mission model where you have to move the lever from one side of the mission model to another. The principle of the attachment is powerful and easy to implement for all kinds of missions.

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.

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.

In this video tutorial, we demonstrate how to release the cargo of a mission model. This mission model is an Airplane. We have to push a lever down to release it. We use an active attachment with a gear wheel.

The topic of this tutorial is the purpose of a system of gears when throwing a ball.

The length of the lever has a certain effect when hitting the ball. In this tutorial, I would like to discuss what it's the effect. 

This video tutorial demonstrates an attachment that flips a mission model. The mission model is attached to the field, but it contains a lever. This lever must be flipped from one side to the other. There is a switch. We use a pinless active attachment with gear wheels, and you can see how this works in the tutorial. There is no use of sensors as we don't need them. We will leave the alignment and positioning for some other tutorials.

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.

In this video tutorial we accomplish the Boccia mission from the FIRST LEGO League 2020 RePlay competition. We use LEGO Mindstorms Robot Inventor robot. In this mission we use an attachment that does three things in the same time - align, push one lever and drop a couple of boxes in a target. It is a complex attachment and it is worth the watch.

This is a true 10 out of 10 video tutorial. The robot accomplishes the Weight Machine mission from the FIRST LEGO League 2021 RePlay competition every single time. The attachment demonstrate a mechanism that performs and is stable on every try

In this video tutorial we look at an active attachment that uses gear wheel and the attachment is general enough to be suitable for reuse. This means that a lot of different missions could be accomplished with the same attachment. The goal of the attachment is to transfer power to a lever through a system of axles and gear wheels. It is interesting that we change the orientation of the gear wheels.

Securely dock the ship that contains the samples and artifacts your team has collected.

Guide the angler fish back to its unexpected home within the shipwreck.

The shark was just tagged for research - release it back into its habitat.

Getting a camera into exactly the right position to capture a shot requires a lot of precise movement and great communication with the actors.

Release the camera down the track to shoot the movie scene.

Visual and audio effects make a powerful impact and can be used to help the audience focus on different parts of the performance.

Set up the music concert by switching on the lights and sound.

Augmented reality transforms a piece of art into an experience.

Rotate the statue to reveal an augmented reality experience.

Immersing viewers so they are surrounded by the art allows them to experience and appreciate it in new ways.

Trigger the immersive experience for the viewer in the model.
