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!

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

The offset beam creates a hook-like motion when rotating the gear, making "hooking" in loops an easy task.

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.

This attachment accomplishes three missions from the FIRST LEGO League MASTERPIECE. It is for the Chain Monster Robot. It accomplishes Mission 10 - Sound Mixer. It also partially accomplishes Mission 14 - Audience Delivery.

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

This attachment is designed to keep the model from coming undone when dropped from a higher distance. It was done so that the robot could use a higher-position attachment to deliver the model while using lower-placed attachments to solve other missions in the same run.

Building instructions for a LEGO Mindstorms EV3 Robot Base with 56mm Tires, Version1. The robot base could be used in robotics competitions as FIRST LEGO League, World Robotics Olympiad and others

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.

This is an example of a robot for Sumo Robotics competitions. Specifically for RoboteX challenge. As most of the Sumo competitions have specific requirements for the robot size this one follows the 15cm x 15cm requirements.

Sumo competitions could be quite fun and interesting as the goal is to push the other robot outside of the ring. 

This attachment is accomplishing three missions from the FIRST LEGO League 2023-2024. It is for the Chain Monster Robot. It solve mission 8 - Rolling camera, mission 12 - Virtual reality artist and mission 13 - Craft creator.

This robot was built by your request. It includes NXT large wheels. The Large LEGOO Mindstorms wheels will give you a faster robot, but be careful, because it will not be that accurate.

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.

Luly is a new STEAM competition robot from LEGO Education SPIKE Prime. We would use in some of the courses. This version of Luly have some light shields to protect the color sensor from ambient light. Check out the courses below and see how Luly is used to complete in a competition.

We had a couple of minutes before starting another robot and we just came up with this robot. If you would like to build a Box Robot, but don't have enough parts this is a good construction that you could learn from. It has a frame. It has three motors. You can add attachments at the top. 

This LEGO Mindstorms EV3 robot chassis has the brick positioned vertically. Interesting idea that could be very useful.

Attachment used to transfer the motion from the motor from a vertical axle to a horizontal axle. Uses two gear wheels. Could be built with LEGO Mindstorms EV3 and LEGO Mindstorms NXT kits.   

This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees. 

It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion

A LEGO Mindstorms EV3 Chassis with wheels at the front. Built with the EV3 set you can use this robot chassis as a base for extending with attachments. 

The goal of this robot attachment is to demonstrate a principle and example for lifting heavy objects vertically. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad. 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.

No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.

Build with LEGO Mindstorms EV3 

This is a robot attachment that could be used to lift object. The gear ratio of this attachment is allows it to lift Heavy objects. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad. The goal of the attachment is to demonstrate the principle and example of an attachment for heavy lifting that could be placed on the robot. 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.
