The flight control system is the core of any drone – acting like a pilot, it manages take‑off, navigation, mission execution, landing, and return. In this video, we break down the three main parts: the onboard computer (the brain), sensors (the eyes and ears, including IMU, GPS, barometer, and ultrasonic), and actuators (motors, ESCs, and servos). You'll see how they work together to enable precise path planning, collision avoidance, and autonomous flight – with real‑world examples like logistics delivery and urban building inspection. Essential viewing for anyone interested in drone tech, robotics, or UAV systems!
