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.

Run 2 - M01 - Push, Pull, Grab

This lesson presents a solution for Mission 01: Surface Brushing in the FIRST LEGO League 2025-2026 UNEARTHED competition. You’ll see how one passive attachment can clear both soil deposits, collect the brush, and use the mission model itself to guide the robot into position.
