FLL 2025: Rotation Work - Smaller Pancake accomplishing M11 Angler Artifacts

For Mission 11: Angler Artifacts in the FIRST LEGO League 2025-2026 UNEARTHED competition, the Smaller Pancake box robot does not simply drive into the model. With the geared Angler Artifacts attachment, it pivots into position, meshes with the mission gears, and raises both the flag and the artifact before heading toward the right base.

Program for Swing Game - LEGO SPIKE Prime robot - LSAv3.4.5.llsp3

This program makes the Swing Game - LEGO SPIKE Prime robot move the two LEGO figures based on input from their respective controllers.

The color sensor controller uses the colored plate above it to determine movement. If the sensor detects blue, the LEGO figure moves forward. If it detects purple, the figure moves backward. Any other color will make it stop.

The motor controller works similarly. If the motor turns more than 30 degrees forward, the LEGO figure moves forward. If it turns more than 30 degrees backward, the figure moves backward. If it stays within that range, the figure stops.

The goal of the game is for both LEGO figures to reach the center without tipping the swing to either side. Good luck—and have fun!
