ROS is a robot operating system originally developed in 2007 under the name switchyard by the Stanford Artificial Intelligence Laboratory in support of the Stanford AI Robot (STAIR[1]) 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 [1][2].
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 towards a Unix-like system (Ubuntu Linux is listed as 'supported' while other variants such as Fedora and Mac OS X are considered 'experimental') but is intended to be cross-platform. At present Windows is listed as having 'partial functionality' [3].
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 stacks) 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.
Applications
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, GPU and clusters.
- Logging
- Parameter server
- Test systems
ROS Package application areas will include
- Perception
- Object Identification
- Segmentation and Recognition
- Face Recognition
- Gesture Recognition
- Motion Tracking
- Ego-motion
- Motion Understanding
- Structure from motion (SFM)
- Stereopsis Stereo vision: depth perception from 2 cameras
- motion
- Mobile Robotics
- control
- planning
- grasping
Ports to robots and boards
