The soil deposits are cleared consistently, but the brush exposes the design's real maintenance point: loose rubber bands or an awkward entry angle can let it escape. The recording also catches a small gravity-related disturbance to the flowers. Watch this tutorial for an honest look at how repeated testing turns minor imperfections into practical improvements before competition.

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.
