APM (ArduPilot Mega)

APM (ArduPilot Mega) is an open-source flight controller software that enables drones, planes, and other robotic vehicles to fly automatically with precision. It acts as the brain of the vehicle, processing data from sensors like GPS, gyroscopes, and accelerometers to maintain stability, navigate, and execute pre-planned routes. Users can customize flight parameters, set waypoints, and implement autonomous missions without manual control. APM is widely used in DIY and professional drone projects for its flexibility, reliability, and community support, making autonomous flight accessible and adaptable across various applications.
