Building instructions for a LEGO Mindstorms EV3 Active attachment for changing gear orientations

Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the second attachment from the series.

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.

This attachment is accomplishing three missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot

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.

This is a heavy lifting attachment and it can lift mission models vertically. It is build entirely from LEGO MINDSTORMS Robot Inventor 51515 parts. This is one of the more complex and interesting attachments that we demonstrate in the course and it show how a few gear wheels and levers could be used to change the motion from circular to linear. This is powerful concept that could be very valuable during FIRST LEGO League competitions.

If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.

Built from LEGO Mindstorms EV3 parts. 

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 5th mission of the FLL Cargo Connect competition.

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 3rd mission of the FLL Cargo Connect competition.

We use this attachment to demonstrate the principle of an active attachment. This is an attachment activated from the motor. It has one level attached to it. It could be reused. The attachment transfers power from the motor to the end of the lever and we can accomplish missions like the Power Switch mission from the FLLCasts Off-season mission models.

This attachment is accomplishing three missions and partly two more missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot

This reusable attachment could easily be placed on the side of a LEGO MINDSTORMS Robot Inventor robot and accomplish different missions that require the robot to interact with mission models. It uses gear wheels.

This attachment is accomplishing three missions and partly one more mission from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot. It solve mission 6 - HYBRID CAR, mission 14 - TOY FACTORY and mission 15 - RECHARGEABLE BATTERY. It partially solves mission 2 - OIL PLATFORM.

This is an active attachment with gears built from LEGO Education SPIKE Prime robotics set. The goal is to do a precise drop. The attachment could be used for both cargo items.

Introducing Kufar! In Bulgarian, Kufar means "suitcase," and just like a suitcase, this robot is easy to "pack" with different attachments for each task.

Unlike traditional box robots, Kufar is an "out-of-box" design, enabling fast, easy attachment swaps. This flexibility allows teams to build a new chassis with customized attachments for each run, making transitions quick but requiring more parts and careful handling due to its gear transmission, which can sometimes cause gear slippage or play.

To improve precision, Kufar’s gear transmission is optimized for lower speeds. Kufar also includes a color sensor to detect specific colored bricks on attachments and a force sensor to start corresponding programs. With two motors for movement and one for attachments, Kufar is compact, efficient, and easy to handle, especially with its sturdy top handle.

We thoroughly enjoyed exploring this innovative concept and hope you find it equally fun and inspiring!

These are 3D building instructions for an active pinless attachment from LEGO Education SPIKE Prime set. The attachment is used along with the Gazon robot to push mission models.

Forth version of a reusable gear attachment. Again, it powers two axles and this time there is a lever connected to one of the axles.

First version of a reusable gear attachment. By following the same principle for assembling the attachments you can change the direction of the gear wheels and build powerful attachments that could accomplish missions in any direction.

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 9th mission of the FLL Cargo Connect competition.
