Rather than forcing the scale down, this solution lets gravity finish the job. In Mission 10: Tip the Scales from the FLL UNEARTHED season, the Smaller Pancake box robot uses a passive pinless attachment to lift the green cover just enough for the scale to tip, then catches the pan as it reverses.

The tutorial explores the simple latch, the low-friction mounting, and the base setup behind this two-action run. It is an inventive example of working with the natural behavior of a mission model instead of fighting it.

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.
