# PX4 自动驾驶仪用户指南
[](https://github.com/PX4/PX4-Autopilot/releases) [](https://discuss.px4.io//) [](https://discord.com/invite/dronecode)
PX4 is an open-source autopilot for drones and autonomous vehicles. It runs on multirotors, fixed-wing, VTOL, helicopters, rovers, and more. This guide covers everything from assembly and configuration to flight operations and development.
:::warning
本指南适用于_development_ version of PX4 (`main` 分支)。
使用 **版本** 选择器查找当前的 _稳定_ 版本。
自稳定版本发布以来的已记录变更，收录在不断更新的(releases/main.md ) 中。

## For Developers
:::tip
Building on PX4 or extending the platform? Start here: [Development Guide](development/development.md). Set up your [dev environment](dev_setup/config_initial.md), [build from source](dev_setup/building_px4.md), run [SITL simulation](simulation/index.md), or integrate via [ROS 2](ros2/index.md) and [MAVSDK](https://mavsdk.mavlink.io/).
:::
## 入门指南
Start with [Basic Concepts](getting_started/px4_basic_concepts.md) for an overview of the flight stack, flight modes, safety features, and supported hardware.
## Build a Vehicle
Pick your frame type: [Multicopter](frames_multicopter/index.md), [Fixed-Wing](frames_plane/index.md), [VTOL](frames_vtol/index.md), [Helicopter](frames_helicopter/index.md), or [Rover](frames_rover/index.md). Each section covers complete vehicles, kits, and DIY builds. For assembly instructions see [Assembling a Multicopter](assembly/assembly_mc.md) or the equivalent for your frame.
## Configure and Tune
Once assembled, follow the configuration guide for your vehicle type (e.g. [Multicopter Configuration](config_mc/index.md)). This covers sensor calibration, flight mode setup, and tuning.
## 硬件
The [Hardware Selection & Setup](hardware/drone_parts.md) section covers flight controllers, sensors, telemetry, RC systems, and payloads. See [Payloads](payloads/index.md) for camera and delivery integrations.
## Fly
Read [Operations](config/operations.md) to understand safety features and failsafe behavior before your first flight. Then see [Basic Flying (Multicopter)](flying/basic_flying_mc.md) or the equivalent for your frame type.
## 技术支持
Get help on the [discussion forums](https://discuss.px4.io/) or [Discord](https://discord.com/invite/dronecode). See the [Support](contribute/support.md) page for diagnosing problems, reporting bugs, and joining the [weekly dev call](contribute/dev_call.md).
