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 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.

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

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.

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

This attachment for the Nautiq robot is designed to collect the Plankton and Seabed Sample, deliver the Unknown Creature, and accomplish M11 Sonar Discovery in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It enables multiple tasks to be completed efficiently in a single run.

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 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.

"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 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.

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 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.
