选择飞控
Flight controllers are the "brains" of an unmanned vehicle. PX4 can run on many flight controller boards.
在选择飞控板时你应当考虑飞机的物理尺寸限制、想要进行的活动以及必不可少的成本。
Pixhawk 系列
Pixhawk Series open-hardware flight controllers run PX4 on NuttX OS. With many form factors, there are versions targeted towards many use cases and market segments.
Pixhawk Standard Autopilots are used as the PX4 reference platform. They are supported and tested by the PX4 development team, and are highly recommended.
Manufacturer-supported Controllers
Other flight controllers are manufacturer-supported. This includes FCs that are heavily based on the Pixhawk standard (but which are not fully compliant), and many others.
Note that manufacturer-supported controllers can be just as "good" (or better) than those which are Pixhawk-standard.
用于计算密集型任务的无人机
Dedicated flight controllers like Pixhawk are not usually well-suited for general purpose computing or running computationally intensive tasks. For more computing power, the most common approach is to run those applications on a separate onboard Companion Computer. Some companion computers can also run PX4 on a separate DSP, as part of the same autopilot board.
Similarly, PX4 can also run natively Raspberry Pi (this approach is not generally considered as "robust" as having a separate companion or using a dedicated DSP):
可运行 PX4 的商业无人机
PX4 is available on many popular commercial drone products, including some that ship with PX4 and others that can be updated with PX4 (allowing you to add mission planning and other PX4 Flight modes to your vehicle).
