Introduction to ROS

The ecosystem effect

Because ROS standardizes how components communicate, it also enabled an ecosystem of shared, reusable packages: navigation stacks, SLAM implementations, motion planning libraries like MoveIt, and drivers for hundreds of specific sensors and motors. A team building a new mobile robot doesn't need to write path planning from scratch, they can bring in an existing, battle-tested package and focus their engineering effort on what's actually unique about their robot.

This is a major reason ROS spread from academic labs into commercial deployment. Companies building wildly different robots, from agricultural robots to warehouse AMRs to research humanoids, can all sit on the same underlying communication layer and pull from the same pool of open-source packages, rather than each reinventing navigation and perception independently.
