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.
