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.

This attachment is accomplishing three missions from the FIRST LEGO League 2023-2024. It is for the Chain Monster Robot. It solve mission 11 - Light show. It partially solves mission 14 - Audience delivery.

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.

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 set of two attachments for the Nautiq robot is designed to solve multiple missions from the FIRST LEGO League 2024‑2025 SUBMERGED competition. It completes M05 Angler Fish, collects 4 Krills for M12 Feed the Whale, gathers all Reef Segments for M03 Coral Reef, and collects all Samples for M14 Sample Collection. The two-attachment design allows for efficient execution of multiple tasks in a single run.

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.

The rotation frame requiers an NXT large double gear wheel that is not available at the EV3 set. You can use the instructions below to construct a similar mechanism from Mindstorms EV3 set

A FIRST LEGO League 2023-2024 attachment for the MiniBox Robot.

This attachment is designed to detach, once it completes its purpose. This is done, so that the team loses less time switching attachments in the base, lowering the chance of human error during the competition.

Second version of a reusable gear attachment. This time the black gear wheel is at the top. It is useful when you are constrained by space.

Building instructions for this part of the BigDaddy competition robot

This attachment for the Nautiq robot is designed to accomplish M12 Feed the Whale in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It demonstrates how to use mission models as part of a passive mechanical trigger and how to apply carabiner mechanisms for purposes other than locking.

This is an attachment for Kufar - Easy SPIKE Prime out-of-box robot. The attachment solves the light show mission using rubber bands! It works well, but it does depend on how new your model is. On newer models it can work with only 2 red rubber bands or even with 2 yellow and 2 red. Find the best combination for your field.

The trigger for the light show mechanism also releases Anna the Museum Curator and the masterpiece on the pedestal.

This is an attachment for Kufar - Easy SPIKE Prime out-of-box robot.It collects Izzy using a rubber band mechanism, solves the M13 Craft Creator with a hook and M12 Virtual Reality Artist using a gear that goes into the mission model.

Third version of a reusable gear attachment. In this scenario a single motor could power two different axles in two different directions. If you use it to accomplish a mission do not forget to send us a video. We would love to see it.

You can position the motors on the construction in a number of different ways. We are exploring the advantages and disadvantages of each of them. These are building instructions for the first way to position the LEGO Mindstorms EV3 motors.

With this LEGO robot attachment from LEGO Mindstorms Robot Inventor we accomplish the Rowing Machine from FIRST LEGO League 2020. The attachment works like a hook that catches the wheel of the Rowing Machine mission model and pulls on it. There are gear wheels that transfer the power from the robot motors to the hook at the end. This attachment shows the principle of catching things

This was an idea. You would we demonstration a multi-axle power and rotation transmitting box. Well, here it is. Build it. Start it. And see how the power from the motor is transmitted through different axles. The lever will demonstrate it.
