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.
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.
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.
Probably the simples trick for pinless attachments that we've found. It is a construction build in just three steps. Simple as that. But it has a lot of potential to teach you how to use pinless attachments. Pinless attachments are very useful during FIRST LEGO League and World Robot Olympiad competitions.
In this episode we continue from Episode 55 and we improve the durability and stability of the attachment for a LEGO Mindstorms EV3 robot. Many times attachments are not very stable which results in gaps between parts. The goal of the video is to give basic construction ideas.
Rubber bands can be quite powerful. Based on several requests from you we are starting a series on using the LEGO Rubber bands available in the Mindstorms set.
In part one we build an attachment that uses a rubber band to solve a competition challenge. The rubber band was released with the use of a motor. In this video we are removing the dependency on the motor and you could use the motor for other missions.
Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down.
Reusable attachments are our favorite. They could be used in a number of different scenarios especially on robotics competitions like FIRST LEGO League/World Robotics Olympiad. This tutorial shows how this reusable attachment could accomplish a mission for lifting a lever. It uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
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.
One of the simplest tricks in the game - move, complete the mission and leave the attachment with the mission model. You don't have to return the attachment to the base. On some competitions there might be penalties, but it might be worth it, as you save time to complete another mission. This works especially well with large attachments.. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This quick pinless attachment is designed for collecting parts by pushing them. It shows the principle of putting a robot of an attachment in a very fast manner. Such attachments are popular at the FIRST LEGO League competition. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
