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.

FIRST LEGO League 2025-2026 UNEARTHED with SCRATCH - Solutions and Review with Smaller Pancake Box Robot from LEGO Education SPIKE Prime
The FIRST LEGO League 2025-2026 UNEARTHED competition challenges teams to recover artifacts, work around delicate structures, and complete several actions efficiently. This course explores practical solutions using the compact Smaller Pancake box robot.
You’ll study a variety of mission strategies and attachment designs, including active and passive mechanisms, gears, hooks, rubber bands, gravity-powered actions, and alignment techniques. The tutorials explain not only what the robot does, but also why each design and programming decision improves the run.
Each main tutorial is paired with a 10 out of 10 reliability test, showing how consistently the solution performs and how details such as starting position, tire grip, attachment preparation, and mission-model movement can affect the result.
To support fair play, our complete mission solutions are published only after the season has ended. Before starting the course, we recommend reviewing the FIRST LEGO League robot game guide.
