A rotating hook does most of the heavy lifting in this solution for Mission 9: What's on Sale in the FLL 2025 UNEARTHED competition. The Smaller Pancake box robot uses the gear-driven M09 attachment to raise the roof, release it cleanly, and lift the market wares during the same return movement.

The tutorial follows the power path from the robot's drive gear to the front arm and explains how reversing the gear frees the hook at exactly the right moment. It also covers the small mounting and starting-position details that keep the arm aligned with the roof support.
