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.  

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.

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

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

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.

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 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.

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.

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.
