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.
