Building instructions for the Rubber Band Attachment

- note that you could attach it to the brick both sides, depending on which technique you would like to test. Use the video as a reference.

This construction uses a differential. Both wheels could turn with different speed and this makes a construction much more stable when turning. 

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!

This attachment is accomplishing four missions from the FIRST LEGO League 2023-2024. It is for the Chain Monster Robot. It solve mission 3 - Immersive Experience. It partially solves mission 14 - Audience delivery and mission 15 - Expert delivery by delivering Izzy the Skateboarder to the Skate Park and Emily the Visual Effects Director in Cinema.

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 flip attachment from LEGO MINDSTORMS Robot Inventor 51515 set is design to flip parts. It can flip a manhole for example, but could also flip other parts. The principle of flipping is quite interesting as it uses two axles and a border.

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 is an attachment positioned below the robot and used for when we need to push something with the robot. It keeps the cargo in place while pushing. In this way we can achieve a consistent behavior with the robot, which is what we all want

This is an pinless robot attachment designed for taking loops. It's built with LEGO MINDSTORMS Robot Inventor parts and it demonstrates how to collect a loop while moving with the robot. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. There are other attachments that are designed for taking a loop and locking it so that it does not fall, but they are more complex. Search for 'Carabiner' at FLLCasts.com
