Long runs are an excellent test of consistency. In this ten-attempt tutorial from the FIRST LEGO League 2025–2026 UNEARTHED competition, we put the Smaller Pancake box robot and the M14 and M15 transport attachment through one of the longest runs on the field.

The attachment proves highly reliable throughout the test, with most attempts completing the full transport sequence successfully. The few later contacts with the Mineshaft Explorer highlight an important lesson: over a full-field run, even a tiny variation in the starting position can become a much larger error by the time the robot reaches its destination.

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.
