Robot Operating System (ROS) is a software framework for robot software development, (see also Robotics middleware) providing operating system-like functionality on a heterogeneous computer cluster. ROS was originally developed in 2007 under the name switchyard by the Stanford Artificial Intelligence Laboratory in support of the Stanford AI Robot STAIR  project. As of 2008, development continues primarily at Willow Garage, a robotics research institute/incubator, with more than twenty institutions collaborating in a federated development model.
ROS provides standard operating system services such as hardware abstraction, low-level device control, implementation of commonly used functionality, message-passing between processes, and package management. It is based on a graph architecture where processing takes place in nodes that may receive, post and multiplex sensor, control, state, planning, actuator and other messages. The library is geared toward a Unix-like system (Ubuntu Linux is listed as 'supported' while other variants such as Fedora and Mac OS X are considered 'experimental').
ROS has two basic "sides": The operating system side ros as described above and ros-pkg, a suite of user contributed packages (organized into sets called metapackages) that implement functionality such as simultaneous localization and mapping, planning, perception, simulation etc.
ROS is released under the terms of the BSD license, and is open source software. It is free for commercial and research use. The ros-pkg contributed packages are licensed under a variety of open source licenses.
In August 2013, a blog posting announced that Willow Garage would be absorbed by another company started by its' founder, Suitable Technologies; no announcement as to the fate of continued ROS development had been made by November 2013.
ROS areas include:
- A master coordination node
- Publishing or subscribing to data streams: images, stereo, laser, control, actuator, contact ...
- Multiplexing information
- Node creation and destruction
- Nodes are seamlessly distributed, allowing distributed operation over multi-core, multi-processor, GPUs and clusters
- Parameter server
- Test systems
ROS Package application areas will include:
- Object Identification
- Segmentation and recognition
- Face recognition
- Gesture recognition
- Motion tracking
- Motion understanding
- Structure from motion (SFM)
- Stereo vision: depth perception via two cameras
- Mobile robotics
ROS -Industrial is a BSD-licensed “hardware-agnostic” software development program to create a Unified Robot Description Format (URDF) for industrial robots.
