PX4 + ROS 2 Architecture Explained: Flight Control, Perception, and Autonomy
PX4 and ROS 2 divide an autonomous vehicle into two complementary systems: a real-time flight controller and a higher-level autonomy computer. Here is how the components communicate—and where your code should run. Read more...
DroneCAN vs. Cyphal: Why Avian Automata Is Building Toward Cyphal
DroneCAN is a mature and practical choice for today’s PX4 vehicles, including systems built around the 305AP. Cyphal provides the plug-and-play support, redundant links, structured interfaces, and distributed architecture needed for the next generation of larger autonomous systems. Read more...
PX4 vs. ArduPilot for Autonomy Research: Which Should You Choose?
PX4 and ArduPilot are both capable open-source autopilots, but PX4 offers several advantages for ROS 2, companion-computer autonomy, custom flight modes, and research-focused development. Read more...
