Discover why this solution achieves a perfect 10 out of 10 successful runs in the FIRST LEGO League 2025-2026 UNEARTHED competition. Using the Smaller Pancake box robot together with this passive attachment, we analyze the design choices that make the completion of Mission 15: Site Marking and Mission 12: Salvage Operation remarkably consistent.

Rather than simply watching successful attempts, you'll learn how the attachment stabilizes the robot against the mission model, why combining several actions into one continuous movement improves reliability, and how a carefully designed passive mechanism minimizes the chances of failure.
If you want to understand what separates a good run from a highly repeatable one, this analysis will help you apply the same principles to your own competition robot.

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.
