# PX4 开发

本章节讲述了如何支持新的无人机/无人车类型及变种，如何修改飞行算法，如何添加新的飞行模式，如何集成新的硬件，如何通过外部飞控和PX4通信。

它解释了如何：

- Get a [minimum developer setup](../dev_setup/config_initial.md), [build PX4 from source](../dev_setup/building_px4.md) and deploy on [numerous supported autopilots](../flight_controller/index.md).
- 理解[PX4系统架构](../concept/architecture.md)及其他核心概念。
- 学习如何更改飞行栈及中间层：
  - 修改飞行算法并添加新的 [飞行模式](../concept/flight_modes.md)。
  - 支持新的 [airframes](../dev_airframes/index.md)。
- 学习如何将PX4集成到新的硬件上：
  - 支持新的传感器和执行器, 包括摄像头、测距仪等。
  - 修改PX4使之能够在新的自驾仪硬件上运行。
- [Simulate](../simulation/index.md), [test](../test_and_ci/index.md) and [debug/log](../debug/index.md) PX4.
- 与外部机器人的 API 进行联调通信/集成。
