In this tutorial, we add another mission to our current program. This mission is - hanging the Gecko from the FIRST LEGO League Animal Allies.
In the final video we explore how to trigger the release of the attachment with just a rubber band. The release is triggered with a gear wheel that rotates in a specific way. This saves speed, does not require additional LEGO Mindstorms motor and is precise enough for a competition.
Try to build the attachment following the instructions. Use it to actually solve a mission from any competition (like taking loops)
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
If you've done the calculation following the previous tutorials you would arrive at a result of 18.75 rotations. But this is not the correct answer. The calculation is wrong, because the math model that we've built, although kind of obvious, is not correct. When experimenting the correct number of rotations would be 37.5. This is a large difference. Two times larger. Exactly two times large. Something should be happening here - and this thing is "planetary mechanism"
In this tutorial, we add another mission to our current program. This mission is - hanging the Gecko from the FIRST LEGO League Animal Allies.
This attachment accomplishes the Into Orbit Extraction mission from the FIRST LEGO League Into Orbit 2017-2018 competitions. The based of the robot is the SUV Competition Box Robot from LEGO Mindstorms EV3.
The program for this attachment is at https://www.fllcasts.com/programs/2hpdg9-fll-2018-attachment-to-accomplish-the-into-orbit-extraction-05-robot-game-missions-program.
What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?
With this series of videos we are looking at FIRST LEGO League 2013 Nature's Fury competition and we are building a robot for accomplishing some of the mission. It would be a tutorial with at least four parts and we are building a complex attachment that could catch, lift and release different parts with only one motor and rubber bands. Not one, not two, but three movements with only one motor.
Third, and last video of this series on how to use ONE attachment to solve the FLL 2014 World Class missions.
The attachment is now so advanced that we can do two tasks at once with it in order to solve the FIRST LEGO League 2014 World Class Search Engine Mission.
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments.
In this tutorial we demonstrate how a Drop Mission could be accomplished with a Drop Attachment. The robot attachment could be adapted to other drop missions in FIRST LEGO League/World Robotics Olympiad and other robotics competitions. The principle is the same. The tutorial uses Luly, 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.
This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Replay Basketball mission and it is the second attachment for this mission. The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.
We've deprecated it because we build a better attachment
This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Replay Treadmill mission . The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.
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.
