Can anybody suggest a good tutorial on ROS for beginners? Did AAC make any blog/video tutorial on ROS?

 

If there were, perhaps it might say what ROS means.

 

In programming context ROS can mean,

Real Operating System
Rich Operating System
Robot Operating System

as opposed to RTOS. Take your pick.

Rich Operating System
A rich operating system (ROS) is the base for conventional computing environments. Its name derives from the rich number of features for general-purpose applications that it comes with. In rich operating systems, the priorities are usually put on multitasking, resource management, and user interface functionality. What are the examples of such systems? Among others:

• Windows,
• Linux,
• macOs,
• Android.
