For Developers
TIP
Building on PX4 or extending the platform? Start here: Development Guide. Set up your dev environment, build from source, run SITL simulation, or integrate via ROS 2 and MAVSDK.
入门指南
Start with Basic Concepts for an overview of the flight stack, flight modes, safety features, and supported hardware.
Build a Vehicle
Pick your frame type: Multicopter, Fixed-Wing, VTOL, Helicopter, or Rover. Each section covers complete vehicles, kits, and DIY builds. For assembly instructions see Assembling a Multicopter or the equivalent for your frame.
Configure and Tune
Once assembled, follow the configuration guide for your vehicle type (e.g. Multicopter Configuration). This covers sensor calibration, flight mode setup, and tuning.
硬件
The Hardware Selection & Setup section covers flight controllers, sensors, telemetry, RC systems, and payloads. See Payloads for camera and delivery integrations.
Fly
Read Operations to understand safety features and failsafe behavior before your first flight. Then see Basic Flying (Multicopter) or the equivalent for your frame type.
