Robot Operating System? |ROS| Really an Operating System??

The Robot Operating System (ROS) is a set of software libraries and tools that help you build robot applications
ROS is not an operating system but a meta operating system meaning, that it assumes there is an underlying operating system that will assist it in carrying out its tasks.
Why should you use ROS?
ROS is a great choice for robot programming and automation due to the following reasons:
It is free, open source and has a large community of contributors, developers and users.
It provides a software platform that enables developers to quickly develop, simulate and test their algorithms.
It can be used on multiple hardware platforms and is scalable.
It allows you to use multiple programming languages, so you can choose the language you are most comfortable with.
It has powerful libraries that provide robust capabilities like 3D vision, motion planning, simulations, etc.
