This is not the usual straight trip from base to mission model. For Mission 7: Heavy Lifting in the FLL UNEARTHED season, the Smaller Pancake box robot deliberately travels outside the mat, uses the table wall as a reference, and reaches the Millstone with an active pinless attachment.

Because contact with the wall introduces slight variation, the front beam is designed to succeed in more than one way: it can catch the loop or push the Millstone free. The tutorial explains the unusual route, the table clearance to consider, and why keeping a backup plan for this mission is still sensible.

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.
