ROS 2 in industrial robotics: where it fits
DDS middleware, real-time profiles, and the ROS-Industrial consortium — a controls engineer's map of the Robot Operating System.
DDS
Pub/sub middleware standard; the transport under ROS 2.
Data Distribution Service: a publish/subscribe middleware standard with rich QoS (reliability, deadlines, durability). ROS 2 uses DDS as its transport, and it appears in military, medical, and some industrial systems.
