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.
Sympho is named after Symphonium, the first company to manufacture music boxes.
The robot uses a color sensor to detect whether the box is closed. When you open it, the robot can play music and spin something with the motor. You can build anything you like on top!
This attachment for the Nautiq robot is designed to accomplish M15 Research Vessel in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It includes one detachable part: the hook is removed after collecting the Research Vessel, and the remaining part is used to deliver it to its target location.
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.
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.
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 for the Nautiq robot is designed to collect the Trident Parts for M14, deliver the Shark for M02, and collect one Krill for M12 in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It features a passive trigger for the krill collection and aligns the robot with the mission model before collecting the trident parts.
This attachment for the Nautiq robot is designed to accomplish M07 Kraken’s Treasure and M06 Raise the Mast from the FIRST LEGO League 2024‑2025 SUBMERGED competition. It features a passive treasure chest collecting mechanism and uses hooks to restrict the inertia-driven movement of the Mast, allowing fast movements without triggering it prematurely.
This set of two attachments for the Nautiq robot is designed to collect and deliver the scuba diver for M01 Coral Nursery and M04 Scuba Diver, collect the shark for M02 Shark, and flip the coral reef for M03 Coral Reef in the FIRST LEGO League 2024‑2025 SUBMERGED competition. One attachment is mounted from above, and the other from below, allowing efficient execution of multiple missions in a single run.
This attachment for the Nautiq robot is designed to lift the coral for M01 Coral Nursery from the FIRST LEGO League 2024‑2025 SUBMERGED competition. It performs two actions simultaneously: lifting the mission model loop and opening the door that holds the Reef Segments.
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 attachment for the Nautiq robot is designed to collect the Krill, the Reef Segments, and the Water Sample, while accomplishing M05 and M10 in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It combines multiple functions to complete several missions efficiently in a single run.
Building instructions for a robot for the World Robotics Olympiad Sputnik competition. This is the light version without the lift at the top.
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.
