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 M8 Artificial Habitat of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a simple active pinless attachment mounted at the front of the robot for precise engagement with the mission model.

The goal is a perfect 10 out of 10 runs by positioning all four crabs upright with their yellow bases touching the mat. You can find the full explaining tutorial here.

This video tutorial focuses on accomplishing M8 Artificial Habitat of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a simple active pinless attachment mounted at the front of the robot, designed for precise engagement with the mission model.

The goal is to position all four crabs upright with their yellow bases touching the mat for maximum points, a task requiring careful alignment and controlled movements. While it is possible to complete the mission with fewer crabs upright, this run is programmed for the full score, using dedicated movement commands in a separate run for maximum accuracy. This approach combines a reliable mechanical design with precise navigation to meet the mission’s demanding scoring conditions.

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).

You can watch the detailed step-by-step explanation in the full tutorial here.

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 M10 Send Over the Submersible 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 where the submersible reaches the opposing field, and the robot disengages without touching the mission model at the match’s end.

The run uses a simple pinless attachment with stopping beams for consistent positioning, combined with programming that integrates a parallel timer for perfect match-end execution. This setup gives the robot the highest possible success rate for both mission requirements across repeated trials.

This video tutorial focuses on accomplishing M10 Send Over the Submersible of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a simple pinless attachment that engages with the front gearwheel of the robot to raise the yellow slider. Built-in stopping beams ensure the attachment always starts from the same position for consistent operation.

This minimalistic but reliable design allows the robot to perform the lift with stability and repeatability, making it well-suited for a time-sensitive mission. The attachment’s simplicity also enables quick setup between runs, keeping it competition-ready.

This video tutorial focuses on accomplishing M11 Sonar Discovery and M12 Feed the Whale of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot. The goal is to achieve 10 out of 10 successful completions, with the robot reliably rotating the sonar and feeding the whale in every trial.

The run uses a combined two-part attachment where the front section opens the whale’s mouth and drops the krill while the rear section uses a chain and hook mechanism to rotate the sonar. The programming ensures precise timing, correct hook positioning, and a small forward adjustment to avoid snagging, enabling consistent results across all attempts.

This video tutorial focuses on accomplishing M11 Sonar Discovery 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). The run uses a combined two-part attachment for maximum efficiency. The front section is designed to drop the krill into the Whale for M12, using a stationary beam to open the whale’s mouth and an angled beam to tip the krill container so they fall inside. Wheels are added as counterweights to prevent the container from opening during movement.

The rear section operates the sonar rotation for M11, using a chain-driven mechanism to transfer power from the robot to the mission model. A hooked beam is integrated at the end, allowing it to easily catch the yellow part of the sonar for rotation. This combined design allows the robot to complete both missions in one smooth, coordinated run without swapping attachments.

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 video tutorial focuses on accomplishing M01 Coral Nursery and M03 Coral Reef of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The aim is to see a consistent accomplishment by lifting the coral tree to the coral tree support and delivering reef segments outside the launch area in one smooth sequence.

The robot uses a motor-powered attachment to lift the coral tree precisely while a side holder secures the collected reef segments. This ensures both missions are completed without losing any pieces during movement. You can watch the full explaining tutorial here.

This video tutorial focuses on accomplishing M01 Coral Nursery and 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 uses a pinless motor-powered attachment specifically designed to raise the coral tree to the coral tree support while delivering reef segments outside the launch area. This attachment was chosen after testing multiple designs, and it proved to be one of the most reliable solutions for this task.

The motor-driven lifting mechanism is mounted using long axle pins due to the gearwheel’s position, and a heavy brick is added on top for extra sturdiness, preventing the attachment from popping off during operation. On the side, a simple holder secures the three reef segments collected in previous runs for easy delivery during this mission. This combination allows the robot to lift the coral tree smoothly, place it accurately, and complete the reef segment delivery in a single, well-coordinated sequence.
