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.
