Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.
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.
This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.
These are 3D Building Instructions for the 3D Cinema mission model for the FIRST LEGO League 2023-2024 MASTERPIECE competition.
This is a pinless attachment built with LEGO Education SPIKE Prime parts and it demonstrates how to use pinless attachments. The goal of the attachment is to quickly place it on the robot without any pins. The attachment is used for pushing. Check out the courses below for more information how to use the attachment. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions
This is a Garbage container and it is fun. As all garbage containers it has only three wheels as one of the wheels is missing. You can also see how one of the wheels is a little different and broken to the side. Like all garbage containers.
The container is useful to play and put things inside.
Suitable for children 6-10 years old. Construct the Garbage Container and leave it for a week for the children to play with. They will spend at least an hour playing with it during the week
This device is designed to be attached to "LEGO Mindstorms Robot with a large inertia cargo". It is a color sensor that goes on the caster wheel of the robot. In this case, the sensor will follow the robot.
Alice is a lovely little bird, with some amazing mechanisms on her feet. It uses two large motors and one medium one as a head, which drives both its wings.
Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.
The attachment is constructed from LEGO Mindstorms EV3 sets.
It is amazingly expensive to send heavy stuff like construction material into space, so scientists and engineers are instead learning how to print what they need in space, using available extraterrestrial elements.
The robot needs to get a regolith core sample and place it into the 3D printer, which will cause the 2 × 4 brick to pop out. The ejected 2 × 4 brick can then be delivered elsewhere for more points.

This is a carabiner attachment for taking loops. It is built with LEGO Education SPIKE Prime parts and it demonstrates how to successfully take loops. The goal of the attachment is to lock the loop after it catches it. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions
Swing game is a SPIKE Prime robot that is a game played by two people. The goal of the game is for both LEGO people to reach the center of the swing, without it tipping over on either side. The LEGO poeple are placed on motors, connected to two technic gear racks, that move along the swing. The motors are moved by two controllers, one using a color sensor and one using a Large motor. If one of the LEGO people moves too far without the other doing the same, the swing will tip and game over! Good luck and have fun!
This robot was designed for the VEX IQ Challenge 2019-2020. It could push four hubs simultaneously. It can carry one. And it call pull itself on the bar at the end of the run. We've used four omni wheels of which the two at the back are the driving wheels.
Demo program can be found at Program for Winner - VEX IQ Competition Robot for the 2018-2019 Challenge.
Vex IQ robot base which could be used with different attachments. The gravity center of this robot is in the backside and it has a lot of space in front for attachments.
VEX IQ version of an Easy Bot. It's simple and appropriate for classes of students.
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.
This is the forth 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.
This is an attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. On a robot most of the time you place attachments on the front/side/top. These instructions show how to build an attachment that could be placed on the front of the robot. The idea is to demonstrate the principle and you can expand and build a more specific attachment for the mission that you are accomplishing. Check the courses in which this attachment is used for more information and tutorials on how to use it.
This is an attachment that could be easily detached after a mission is accomplished. It's built with LEGO Education SPIKE Prime parts and it demonstrates an important principle for building attachments for robotics competitions like FIRST LEGO League/World Robotics Olympiad and others. You move with the robot, you complete the mission and you leave the attachment on the field when the mission is completed. In this way you save time when adding the attachment as it is most of the time pinless and takes a fraction of a second to put it. The attachment is 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.
