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 is an experiment we did that didn't work out for the FLL 2023-2024 MASTERPIECE field, but is interesting nonetheless. It shows how you can take an out-of-box robot and put a steering mechanism on it.

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!
