We experimented with building a box robot powered entirely by chains—a unique approach inspired by the original LEGO MINDSTORMS NXT Robots. Chains like these can be hard to find, but we thought: why not try to power both the robot and its attachments with them? This design not only powers the entire robot but also provides a great demonstration of how and when chains can be effectively used in robotics.

To build this robot, you'll need approximately 180 chain links (part 3711a), which are available in the NXT kits and some Technic sets.

Please note that this robot requires additional components beyond those included in the LEGO Education SPIKE Prime and SPIKE Essential kits. Check out the additional parts required.

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 incredibly compact SPIKE Prime Box Robot is designed for competitions such as the FIRST LEGO League (FLL) and World Robot Olympiad (WRO). Named Whakatae, derived from the Māori word "whakataetae," meaning "competitive," this robot measures 17 LEGO units in length and 15 LEGO units in width. It features two color sensors in front of the wheels for precise alignment, two large motors for movement, and two medium motors for attachments.

The best part? You can build this SPIKE Prime Box Robot using just the Base Set, an additional large motor, and a color sensor!

This simple active pinless attachment for the Nautiq robot is designed specifically to accomplish mission M08 Artificial Habitat in the FIRST LEGO League 2024‑2025 SUBMERGED challenge. It offers a minimalist, efficient mechanism ideal for reliably completing the mission. No motors are required—setup is quick and intuitive. The compact design ensures stable performance and easy integration with the Nautiq robot.

Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.

This attachment for the Nautiq robot is designed to accomplish M10 Send over the Submersible in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It uses a gear mechanism to lift a LEGO axle, allowing the submarine to slide to the other side.

This incredibly compact SPIKE Prime Box Robot is made for competitions like FIRST LEGO League (FLL) and World Robotics Olympiad (WRO). Whakatae (from Maori's word "whakataetae", which means "competitive") is long 17 LEGO units and is with a width of 15 LEGO units. In front of the wheels it has two color sensors which it uses to align. Whakatae also has two Large motors for moving and has two medium motors for attachments!

It's has "V2" in its name, because it's the second version of Whakatae - LEGO Education SPIKE Prime Competition Box robot. The difference between the two is that the first one can be built with only a Large Motor and a Color sensor in addition to the Base set, while this one needs an additional ball bearing. This provides this robot with a lot more stability and can be seen as a true upgrade to the first version.

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 is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.

The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.

When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.

Build with LEGO Mindstorms EV3 parts. 

Robot attachment that shows you how a circular motion could be transferred to linear by using a gear and a rack. The final motion is for pushing and pulling things. 

The attachment could be built from LEGO Mindstorms EV3 and NXT parts. 

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.

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.

Do you remember the Chain Monster Box Robot? This one is the same but without the chains. What is cool about this robot is you can use almost all Chain Monster attachments and build a lot more.

The Unchained Monster box robot requires additional parts on top of the LEGO Education SPIKE Prime and LEGO Education SPIKE Essentials. Check out the additional parts required.

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.

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

Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the third attachment from the series.

For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.

Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
