Video tutorials

If you think that the quick pinless attachments shown in video 63 are quick enough, see this tutorial and you will find out that the quick pinless attachments could be even quicker. These attachments can work without motors but by using the inertia forces.

In this tutorial, we share a tip for organizing robot attachments in the FIRST LEGO League challenge. By designing attachments to hook onto the table edge, you can keep them close at hand for quick swaps, saving time and reducing mistakes.

Options include building hooks into the attachment design or using small separate hooks. This method is used by many teams and is a practical way to stay organized during competitions.

"The devil is in the details". We are improving the Rubber band attachment with a Flywheel by introducing a few small, but important modifications that make the whole robot attachment more stable and reliable. With the conclusion of the series this attachment could be used as a basis for some very interesting STEM demonstrations on energy accumulation and conservation.

On every FIRST LEGO League competition and generally robotics competitions with LEGO robots, we build attachments to accomplish missions and we must accomplish the missions in a limited amount of time. Most of the time we can not accomplish the missions with a single attachment and we have to change attachments. This is where building robot attachments that are easy to remove really makes sense. In this tutorial we discuss some of the things that should be considered in the building Easy to Detach modules and attachments

In this tutorial of the series we would get into more details on how the flywheel works, what's its purpose and how the whole attachment is triggered with the first rubber band.

The third part of the series the goal is to extend the robot attachment so that we could solve the second part of the FIRST LEGO League World Class mission challenge - to take the loop.

“Doing the same with less” can save time and space.

We start with the first mission - trying to build attachments that are small and tidy and the Gazon robot allows us to do so. With a few pictures you can see how the robot should be placed along with all the attachments

In the third run Nightbeast team solves Mission 04 - Crater Crossing and partly Mission 03 -  3D printing and Mission 014 Meteoroid Deflection:

1. Eject the 2x4 Brick by placing a Regolith Core Sample into the 3D Printer.
2. Crater Crossing
3. Tries to score a meteoroid( tries to shoot a ball)

In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow

The video shows why you should not build attachments such as "Crappy Active Attachment For SUV Box Robot". In the video one can see how the knob gear wheels start "jumping", once a force is applied to the lever. 

Inertia triggered attachments does no require the use of a motor. Let the inertia do all the work. These kinds of attachments are very useful at robotics competitions like FIRST LEGO League and World Robot Olympiad. The robot moves, the attachment falls and grabs the ball. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

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.

This is a live video tutorial of an inertia triggered attachment build with LEGO MINDSTORMS Robot Inventor. The attachment, the robot and the mission model are all built from a single 51515 set. The cool thing about inertia triggered attachments is that they are active and are activated without the use of any motors which means that you have the motors for the other missions at FIRST LEGO League competitions. In the tutorial we demonstrate and explain how such attachments works and how they could be used.

In this video tutorial we demonstrate a Grab attachment build from LEGO Mindstorms Robot Inventor 51515 set. The goal of the grab attachment is to accomplish the mission of bringing loops back to base without loosing or dropping them when returning. The principle of the grab attachment also demonstrates how to have a a locking mechanism. In this way there is not way to the loop to escape.

This video tutorials shows how we accomplish a specific mission model from FIRST LEGO League 2022-2023 SUPER POWERED robotics competition. The mission is called - M11 Hydroelectic Dam and in the tutorial we accomplish part of it. In other tutorials when we get back with the SPIKE Kriket box robot we have more time to accomplish the rest of the missions.
