Software in the ROS Ecosystem can be separated into three groups:

The lack of support for real-time systems has been addressed in the creation of ROS 2, a major revision of the ROS API which will take advantage of modern libraries and technologies for core ROS functions and add support for real-time code and embedded system hardware. However, it is possible to integrate ROS with real-time computing code. Despite the importance of reactivity and low latency in robot control, ROS is not a real-time operating system (RTOS). Running sets of ROS-based processes are represented in a graph architecture where processing takes place in nodes that may receive, post, and multiplex sensor data, control, state, planning, actuator, and other messages. Although ROS is not an operating system (OS) but a set of software frameworks for robot software development, it provides services designed for a heterogeneous computer cluster such as hardware abstraction, low-level device control, implementation of commonly used functionality, message-passing between processes, and package management. Robot Operating System ( ROS or ros) is an open-source robotics middleware suite. Linux, macOS (experimental), Windows 10 (experimental)
