As someone who got my start in drones with Lego Mindstorms, I can appreciate the work that went into this. Must watch.
NXTLOG user hknssn13 built this amazing paper airplane machine. My favorite part is the 4th stage, where four linear actuators make the final folds in the airplane. It looks sick when the entire assembly rises up! The project uses 2 NXT microcontroller bricks, 5 servos, 10 DC motors, pneumatics, infrared, and a bunch of sensors.
