PX4 Autopilot

概览

解决什么问题

Open-source flight control stack for autonomous UAV/UGV platforms requiring real-time control, sensor fusion, and ROS2/DDS integration.

主要用例

• Flight control for multicopter, fixed-wing, VTOL, rover
• Autonomous navigation with obstacle avoidance
• Hardware-in-the-loop simulation (Gazebo, jMAVSim)
• Companion computer integration via MAVLink/ROS2

次要用例

• Education and academic research
• Custom payload integration
• Swarm/UAV fleet research

何时使用

考虑使用

• BSD-3-Clause license required
• Active upstream maintenance (last activity 2026-08-16)
• Native DDS/ROS2 support needed
• Pixhawk or NuttX-targeted hardware

采用前需验证

• ? Specific flight controller board support in current release
• ? Real-time OS (NuttX) compatibility with custom hardware
• ? Regulatory certification gaps for intended operation
• ? MAVLink dialect alignment with ground station

从这里开始

采用检查清单

• 需验证 Specific flight controller board support in current release
• 需验证 Real-time OS (NuttX) compatibility with custom hardware
• 需验证 Regulatory certification gaps for intended operation
• 需验证 MAVLink dialect alignment with ground station

以上检查项只有在官方来源确认后才能标记为“已验证”；无法确认的保持未验证。

已知限制与未知项

已知限制

• Steep configuration learning curve
• Limited out-of-the-box support for non-Pixhawk boards
• No formal safety certification (DO-178C, etc.)
