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.

Тhe programming process is streamlined, making it more accessible even for beginners. The design of the attachment significantly influences how the robot moves, simplifying the code and reducing complexity.

The program is way easier due to the form of the attachment that makes the first movement just forward to complete M13 Change Shipping Lanes, and then moving backwards towards M09 Unexpected Encounter. This approach eliminates the need for complex directional adjustments at the start, allowing the programmer to focus on precise positioning later in the sequence. By letting the attachment dictate the natural forward motion initially, the programming logic becomes shorter, cleaner, and easier to debug. As a result, both the initial movement and the reverse action toward M09 can be executed with minimal code changes, ensuring faster development and more reliable performance. Along the way, the robot also partially accomplishes M12 Feed the Whale.

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 demonstrates a 10 out of 10 on M13 Change Shipping Lanes, along with partial completion of M09 Unexpected Encounter and M12 Feed the Whale in the FIRST LEGO League 2024-2025 SUBMERGED Challenge, using the Nautiq box robot (a LEGO Education SPIKE Prime robot).

This video tutorial focuses on accomplishing M13 Change Shipping Lanes, and partially M09 Unexpected Encounter and M12 Feed the Whale of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot).

In this run, the robot flips the shipping lane model, collects the small Krill, and retrieves the Unknown Creature from the field by pushing on the mission model. These tasks are executed with precision to ensure that the robot not only scores the primary mission points but also safely returns the collected elements back to base. The sequence is optimized to minimize travel time between missions while maintaining accuracy and control over the robot’s attachments.

We use a pinless, three-in-one design attachment for completing multiple missions in one run. At the front, an angled rubber band mechanism handles M13 Change Shipping Lanes, allowing the robot to launch straight from base without extra positioning.

On one side, a passive curtain mechanism like a cage captures the single Krill for M12 Feed the Whale. On top, a secure basket catches the Unknown Creature from M09 Unexpected Encounter after a push with the robot’s back. The attachment is optimized for quick and reliable mission execution without additional motors.

This 10 out of 10 video tutorial focuses on the flawless accomplishment of M05 Angler Fish, M09 Unexpected Encounter, M10 Send over the Submersible, and M11 Sonar Discovery of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot.

The run uses a combination of aligning, front, and back attachments to execute multiple tasks in one run, including a rotation transfer system using a single long axle for M11, early execution of M10 for a strategic edge, and sensor-based alignment for precision. Despite the reduced per-run accuracy due to the mission count, this method ensures that when the run works, it secures an exceptionally high score.

This video tutorial focuses on accomplishing M05 Angler Fish, M09 Unexpected Encounter, M10 Send over the Submersible, and M11 Sonar Discovery of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses three attachments in sequence: an aligning attachment at the start to reduce initial inaccuracies, a front attachment for solving M05 and M10 while collecting krill, reef segments, and the water sample, and a back attachment for solving M11, delivering the unknown creature for M09, and collecting plankton and seabed samples.

The front attachment is particularly interesting in this configuration because it integrates two color sensors and one motor directly onto the attachment itself. These sensors are used to align the robot to the black line near M10, while the aligning attachment at the start ensures a precise launch position.

This version of the big run takes on significantly more missions in a single attempt than a standard sequence, which naturally comes at the cost of reduced accuracy. In the current FLL competition format—where only your best score from three attempts is counted—this trade-off can be highly strategic. A run that works perfectly even just once can yield a massive point boost, making this kind of high-reward, lower-consistency approach a potential game-changer for teams willing to take the risk.

This video tutorial focuses on accomplishing M02 Shark, collecting the trident for M14 Sample Collection, and collecting a Krill for M12 Feed the Whale of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). In this series of test runs, our goal is to achieve 10 out of 10 successful attempts, meaning the robot completes all three missions flawlessly in every trial.

The robot uses a pinless attachment with locking beams for stability, enabling it to push the shark into its habitat, trigger a drop wall to catch the Krill, and lower a motorized arm with rubber parts to grab the Trident. This efficient approach ensures consistent results across the attempts while maintaining stability and precision throughout the runs. You can watch the full explaining tutorial here.

This video tutorial focuses on accomplishing M02 Shark, collecting the trident for M14 Sample Collection, and collecting a Krill for M12 Feed the Whale 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 with two locking beams for stability, featuring two main “chambers” and a motor-powered arm with rubber parts for handling multiple mission elements.

The left chamber is used to push the shark from M02 into its habitat, while the opposite side has a passive beam-trigger mechanism to drop a wall and catch the Krill in front of the shipwreck. The motorized arm slowly lowers to grab the Trident from the bottom using rubber parts, a solution that is not 100% reliable due to the challenge of the element but is the best tested option. The side locking beams are essential for keeping the attachment secured during these precise maneuvers, preventing it from detaching during the run.

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.
