One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.
With this attachment we complete the Elevator and Steel construction for the FIRST LEGO League 2019-2020 competition. The attachment is placed on the Whakatae - LEGO Education SPIKE Prime Competition Box robot
A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.
This is an attachment for the Kriket box robot. It demonstrates how to build attachments that glide over the robot, are pinless and could be quickly and easily replaced and changed with another attachment. This attachment also lifts. Quite cool. Quite cool.
With this LEGO Education SPIKE Prime attachment we accomplish the basketball mission from the FIRST LEGO League 2020 RePlay competition. The goal of the mission is to put the ball into the basket and to have the basket up at the end of the round. This is a complex attachment. It uses gear wheels and warm gears to transfer the power from the motor to the top of the attachment. At the top of the attachment there is a wheel with a rope. The rope is build with LEGO Education SPIKE Prime parts. If you have the chance, use a different LEGO rope, but if you don't that this one will be ok.
This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example.
The attachment was used during FIRST LEGO League 2014 Robotics competition.
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.
This attachment is part of a second version of attachments for accomplishing the M07, M08 and M15 where we have to push and collect in the FIRST LEGO League 2022-2023 competition. It is for the Kriket Box Robot and we are doing this second version to make sure there are enough examples of how to use the Kriket box robot.
The interesting part about this attachment is how it connects to the robot. The Kriket has two brown axles that are connected to the motors via a gear mechanism. The attachment is attached to these brown axles which transfer the motor movement to the attachment.
Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.
SIngle robot attachment, many points.
Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.
This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.
This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears
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.
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.
This is the attachment of Team "Nightbeast", with which they solve M01 and M02 from FLL Into Orbit Challenge
This is the attachment to accomplish Fll 2019 M06 mission with the Whakatae. You can see how to attach the attachment to the robot in this tutorial to do.
Building instructions for the LEGO Mindstorms attachment using Rubber Bands
An attachment designed for Heavy lifting. It's build with LEGO MINDSTORMS Robot Inventor 51515 and it has a gear wheels mechanism that allows you to increase the torque and lift really heavy things. Build the attachment and check out the tutorial. This will teach you one more principle that you could use for FIRST LEGO League competitions.
This is the third type of an active geared attachment. "Active" means that is is power by a motor. "Geared" means that it uses gears. "Reusable" means that you can easily extend the attachment with additional parts - eg - you can reuse it. It shows a basic principle of how power is transferred between different axles that have different orientation in space - like when one of the axles is horizontal and the other is vertical. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad and others. It's designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the courses in which this attachment is used for more information and tutorials on how to use it.
The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.
