Concept 01

A robot is a team of programs.

ROS connects focused programs through shared interfaces, so sensing and control can develop independently.

Follow a message through the ROS graph

Camera node: A node performs a job. This publisher turns camera observations into typed messages.

Conceptual flow; the animation does not represent measured timing.

Nodes perform individual jobs.
Topics carry typed streams of messages.
A node can publish one stream and subscribe to another.

Keep this in mind

A camera driver publishes images; a detector processes them without controlling the camera hardware.
