What is ROS(Robot Operating System)?

For all you text-is-boring people, here’s a video version of this blog on my YouTube channel.

Hello there! This is a jargon-less (almost) post talking about what ROS is, what it’s not, and its superstar role in Robotics.

Before we begin, I would like to point out that ROS is not Robotics.
Robotics is still what it was before ROS — a system of hardware + software which perceives and interprets its surroundings, decides how to respond, and takes action to alter the state (of itself + environment) for a mission.
