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.

The first part of a box robot chassis for robotics competitions. The robot is quite large and this is why we split it into two parts - to make it easier to construct it. This is the second part. 

The robot is built with LEGO Mindstorms EV3, with an additional part for the walls used in the second part.

Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.

Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.

This is a real competition robot with three light sensors and a gyro.

This attachment for the Nautiq robot is designed to align the robot to the wall during the FIRST LEGO League 2024‑2025 SUBMERGED competition. It ensures consistent positioning for reliable mission execution.

Building instructions for a Full LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions.

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.

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.

The very first robot that we usually build in a class. 

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.

The "five minute bot with handle" gives an easy and intuitive place for children to hold it. It provides a stronger construction and cables are not included, so that adult assistance with the cables at the end of the building process is 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.

"How do you build a forklift using only gear wheels and levers without a rake"... Ok, we would admit that is a difficult question. It even sounds difficult. So let's start with something easy. A LEGO Mindstorms EV3 robot. It lifts objects in the air. It uses two gear wheels that work together and then move in different directions and are placed perpendicular to each other... This sentence kind of got difficult again... Let me try again.

Follow the building instructions with these 70+ steps and you will have a very nice robot and you will learn a simple trick of how to use gears and change the directions in which they rotate. 

This attachment for the Nautiq robot is designed for missions M13 Coral Reef, M12 Raise the Coral, and M09 Release the Shark from the FIRST LEGO League 2024-2025 SUBMERGED competition. It features a passive mechanical trigger that releases a lever powered by a rubber band. A passive curtain mechanism is included for collecting parts from the field. The attachment is optimized for quick and reliable mission execution without additional motors.

Building instructions for probably the simplest LEGO Mindstorms EV3 Motorcycle that you could think of. Can you think of a simpler? Build it and send it to us.

The motorcycle has one large and one medium motor. Turns are hard, but we will think of solutions for turns. There are also other motorcycles, more complex ones that you could build

• Handlebar - Chopper Motorcycle built with LEGO Mindstorms EV3

• Ninja - Sports Motorcycle built with LEGO Mindstorms EV3

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.
