载具选择

PX4支持空中，表面（地面，水面）以及水下载具。 您可以在机架参考中查看已经经过PX4测试/调整过的载具类型或及其变种（“框架”）。

选择何种机架取决于您需要用来做什么：

• Multicopters offer precision hovering and vertical takeoff, at the cost of shorter and generally slower flight. PX4有可以让它们很容易飞的模式，并且它们是最受欢迎的飞行器。
• Helicopters similar to Multicopters, mechanically more complex, but more efficient.
• Fixed-wing airplanes offer longer and faster flight, and hence better coverage for ground surveys etc. 但是它们比多旋翼更难飞行和降落，并且如果您需要悬停或飞得很慢时，它们就不再合适（例如在勘测垂直建筑时）。
• VTOL (Vertical Takeoff and Landing) aircraft come in a number of types: tiltrotors, tailsitters, quadplanes etc. 它们拥有二者（多旋翼和固定翼）优点：能够像多旋翼那样垂直起飞然后转变到像固定翼飞机那样向前飞行。 They are often more expensive than either multicopters and fixed-wing aircraft, and harder to build and tune.
• Airships/Balloons are lighter-than-air vehicles that typically offer high altitude long duration flight, often at the cost of having limited (or no) control over speed and direction of flight.
• Rovers are car-like ground vehicles. 它们很容易控制，而且常常很有趣。
• Boats are water-surface vehicles.
• Submersibles are underwater vehicles.
