• Passive attachment

In this video tutorial, we demonstrate a full run for the FIRST LEGO League 2024-2025 SUBMERGED challenge, completing all missions in a single sequence. Each mission is shown individually beforehand, with close-up views of how the attachments work and the principles behind their design. All attachments are pinless, making them quick to change during the run, though aligning and loading the robot still requires practice. The strategy involves moving from one base to the other while accomplishing as many missions as possible, including retrying those close to base when needed.

While the complete run takes longer than the official 2.5 minutes, the focus here is on demonstrating reliability, consistency, and the trade-offs between time and scoring points. In some cases, missions are skipped to focus on higher-value tasks, but in this run, we aim to complete them all. The result is a strong performance that comes close to the maximum possible score.

This video tutorial focuses on accomplishing M05 Angler Fish, M09 Unexpected Encounter, collecting samples for M14 Sample Collection, 3 Krill for M12 Feed the Whale, and Reef Segments for M03 Coral Reef of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run achieves a perfect 10 out of 10 score across these missions in one continuous sequence.

The robot collects and delivers samples, gathers krill and reef segments, pushes the Unknown Creature into the Cold Seep, and engages mission models with precision. The path is optimized for efficiency, combining multiple scoring actions with minimal wasted movement. You can watch the full explaining tutorial here.

This video tutorial focuses on solving M05, M09, collecting samples for M14, 3 Krill for M12, and Reef Segments for M03 of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using Nautiq box robot (a LEGO Education SPIKE Prime robot).

This video tutorial focuses on accomplishing M15 Research Vessel of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot. In this series of test runs, the goal is to achieve 10 out of 10 successful deliveries, with the robot pushing the loaded ship to its destination, releasing it cleanly, and moving to the other launch area without a single failed attempt.

The run uses a pinless attachment with a locking mechanism and friction pins to secure the cargo during movement and allow smooth release upon arrival. The precise programming and stable design ensure consistent performance across the trials.

This video tutorial focuses on accomplishing M15 Research Vessel of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless attachment designed to push the ship loaded with cargo to its destination. After the previous run, the hook part is removed and replaced with a locking component that holds the ship securely during transport.

The locking mechanism uses friction pins to keep the ship stable until it reaches its destination, where it can then be released smoothly. This approach ensures the cargo remains secure throughout the journey while allowing for safe delivery and quick unloading at the final position.

This video tutorial focuses on accomplishing M15 Research Vessel of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot. In this series of test runs, the aim is to complete 10 out of 10 flawless retrievals, with the robot successfully latching onto the vessel and pulling it back to base every single time.

This video tutorial focuses on taking the Research Vessel for M15 of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using Nautiq box robot (a LEGO Education SPIKE Prime robot).

This video tutorial focuses on accomplishing M15 Research Vessel of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless latched attachment mounted under the robot for maximum stability. The attachment features a hook that catches the research vessel and pulls it back to the launch area, after which the hook can be removed and the remaining parts reused for the next run.

Important: Before starting this run, ensure the part that locks the boat for the next run is raised; otherwise, the robot cannot hook the vessel correctly. This simple but effective mechanism allows for a quick and reliable retrieval, setting up the next sequence of missions without additional adjustments.

This is a 10 out of 10 video tutorial that focuses on accomplishing M01 Coral Nursery, M02 Shark, M03 Coral Reef, and M04 Scuba Diver of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot).

The robot pushes the shark, flips the coral buds and coral reef, and collects and delivers the Scuba Diver with precision. This efficient multi-mission run is designed for speed and reliability, ensuring maximum points with minimal wasted movement. You can watch the full explaining tutorial here.

This video tutorial focuses on accomplishing M01 Coral Nursery, M02 Shark, M03 Coral Reef, and M04 Scuba Diver of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a two-part pinless attachment designed to complete multiple missions in a single sequence. The small angled surface mounted under the robot flips the coral buds from M01 and pushes the shark from M02, while the front arm catches and delivers the Scuba Diver from the coral nursery to the coral reef support.

The back section of the attachment flips the coral reef from M03 using a friction-pin mechanism that stays straight during travel but drops the horizontal arm at the mission model to push the yellow plate and raise the coral reef. Extra axles on the front arm prevent the Scuba Diver from falling during delivery, ensuring reliable scoring. This coordinated multi-mission approach maximizes efficiency by combining pushing, collecting, and delivering into one smooth run.

This video tutorial focuses on accomplishing M06 Raise the Mast and M07 Kraken’s Treasure of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The point is to achieve a perfect 10 out of 10 score for these interconnected missions in one smooth sequence.

The robot first secures the treasure chest before fully raising the mast, avoiding the mechanism that would otherwise lock the chest in place. This requires precise timing and control to push, lift, and stop at the correct point, then complete the mast-raising motion. You can watch the full explaining tutorial here.

This video tutorial focuses on accomplishing M06 Raise the Mast and M07 Kraken’s Treasure of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless attachment connected to the bottom of the robot, featuring side guides with stoppers for precise mast lifting and a central rubberized section to catch the treasure chest.

The challenge in this run is to collect the treasure before raising the mast fully, as the mission model locks the chest if the mast is lifted too far too soon. The robot must push and lift with great precision, stopping at exactly the right point to avoid triggering the lock, then continue raising the mast to complete the mission. This sequence demonstrates careful mechanical design, accurate programming, and precise timing to accomplish two interconnected missions in one smooth run.

This M12 Water reservoir from FIRST LEGO League 2022-2023 is accomplish in two part with the Chain Monster box robot. The first part is in a previous tutorial. This is the second part where we collect the third water unit. We use a passive attachment to collect this unit.

In this video tutorial we accomplish the FIRST LEGO League 2022-2023 SUPER POWERED mission called M04 Solar Farm. We use the chain monster box robot along with a passive attachment that helps us collect 3 of the energy units. The interesting thing about the mission is the collection of the units, of course, but also the way this robot manoeuvres when there is not enough space. It aligns to the lines, it uses the color and motion sensors. Really advance way to align the robot.

In this video tutorial the Chain Monster LEGO box robot uses a multi-purpose attachment to collect two elements from the FIRST LEGO League 2022-2023 SUPER POWERED field and these are the "water" units on the field. What's interesting is that the contain where the water units are stored could be closed and opened and this allows us to freely move while non of the water units are lost.

This 10 out of 10 tutorial is a complete uncut recording and it shows how the Chain Monster box robot accomplishes 5 missions in a single run and it does this 10 out of 10 times. It is from the FIRST LEGO League 2022-2023 robotics competition.

In this video tutorial we accomplish 5 missions in a single run with the Chain Monster box robot. It accomplishes 5 missions from the FIRST LEGO League 2022-2023 robotics competition.

This video tutorials shows how we accomplish a specific mission model from FIRST LEGO League 2022-2023 SUPER POWERED robotics competition. The mission is called - M11 Hydroelectic Dam and in the tutorial we accomplish part of it. In other tutorials when we get back with the SPIKE Kriket box robot we have more time to accomplish the rest of the missions.

This is a 10 out of 10 tutorial on a basic approach for one of the unique challenges in FIRST LEGO League competitions. This basic approach to a solution is not very consistent, and in some of the next tutorials, we will present a new solution. But we decided to record it to demonstrate how reliable this attachment is when it comes to carrying large objects. That could give you ideas of things to avoid.

In this video tutorial, we demonstrate one of the unique missions of the FIRST LEGO League competitions - we must carry a rather large object from base an leave it on the field. This takes some considerations as other missions must be accomplished before that.
