Dominator is a compact LEGO Mindstorms EV3 Box robot from the family of the Roller Coaster and Kiddo box robots. Similar to the previous two robots, Dominator also can move its front part up, down, left and right. This robot also has the same length of movement as its two predecessors of this type - 8 LEGO pins on the side and up.

The difference is that Dominator has fewer parts and has a perfect center of weight that allows it to use large attachments and lift heavy objects without threatening its stability. The movement on the X and Y axes has the same gear ratio. The light sensors are attached to the movable part of the robot which enables it to both follow a line and recognize the color of various object with height lower than 7 LEGO units.

Meet Kiddo, smaller sister of Roller Coaster. It is smaller, easier to build and easier to control box robot with X-Y moving plate.

The goal of this robot is to have one complex attachment that could move in four directions. With such an attachment you can solve a lot of complex tasks without loosing time changing attachments. It is also quite sturdy and packed

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and is used in the FIRST LEGO League 2025-2026 UNEARTHED competition. It completes Mission 13: Statue Rebuild, collects the other team’s minecart, delivers a flag next to the minecart extraction area, and transports all artifacts from the Right Base to the Left Base.

Attachment frames are used on Base Robot Chassis to make it easier to add and remove attachments very fast. This frame is for the Box Robot 1. It is a single module build with LEGO Mindstorms EV3 parts and it could handle attachment on all sides. 

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.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 12: Salvage Operation and part of Mission 15: Site Marking in the FIRST LEGO League 2025-2026 UNEARTHED competition. It raises the ship, pulls the sand lever to clear the sand, and places a flag in its designated position next to the Salvage Operation mission model.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 14: Forum and Mission 15: Site Marking in the FIRST LEGO League 2025-2026 UNEARTHED competition. It delivers all the artifacts to the Forum and places the flag in its designated position nearby.

Frame for adding attachments on the robot. When using a frame it is very easy to quickly add and remove pinless attachments from the robot. The whole frame could be removed.

The frame contains parts from LEGO Mindstorms EV3.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 10: Tip the Scales in the FIRST LEGO League 2025-2026 UNEARTHED competition. It releases the large scale, latches onto the Scale Pan, and transports it safely back to base.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 11: Angler Artifacts in the FIRST LEGO League 2025-2026 UNEARTHED competition. It aligns the robot with the Angler Artifacts mission model and rotates the gear mechanism to raise both the artifacts and the flagpole.

Active robot attachment for the LEGO Mindstorms EV3 Box robot chassis. The attachment is placed on the top of the robot and uses a system of two gear wheels to transfer the motion to a lever and to .... lift things.

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 02: Map Reveal and Mission 03: Mineshaft Explorer in the FIRST LEGO League 2025-2026 UNEARTHED competition. It pushes two of the topsoil sections aside and lifts the third to extract it. The robot then moves backward and raises the rail, allowing the minecart to travel onto the other team’s field.

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. 

This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and is used to complete Mission 05: Who Lived Here?, Mission 06: Forge, and Mission 07: Heavy Lifting in the FIRST LEGO League 2025-2026 UNEARTHED competition. The attachment positions the robot accurately in front of the mission models and interacts with each mechanism in sequence. In one run, it presses the Forge lever to release the stones, activates the Who Lived Here? model, and pushes a stone into the Right base. In a separate run, it pushes or captures the Millstone and transports it to the Right base.

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 attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 01: Surface Brushing in the FIRST LEGO League 2025-2026 UNEARTHED competition. It pushes and pulls the Soil Deposit to release and extract the Brush.

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.   

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.

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

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.
