ROS is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. It also provides tools and libraries for obtaining, building, writing, and running code across multiple computers. The ROS runtime "graph" is a peer-to-peer network of processes potentially distributed across machines that are loosely coupled using the ROS communication infrastructure. ROS implements several different styles of communication, including synchronous RPC-style communication over services , asynchronous streaming of data over topics , and storage of data on a Parameter Server.

ROS Tutorials Non-Beginners : If you're already familiar enough with ROS fuerte or earlier versions and only want to explore the new build system introduced in groovy and used in hydro and later, called catkin , you can go through more in-depth catkin tutorial here. However, going over all basic Beginner Level tutorials is still recommended for all users to get exposed to new features. If you are new to Linux : You may find it helpful to first do a quick tutorial on common command line tools for linux. A good one is here. This tutorial introduces ROS filesystem concepts, and covers using the roscd, rosls, and rospack commandline tools. This tutorial covers using roscreate-pkg or catkin to create a new package, and rospack to list package dependencies. This tutorial introduces ROS graph concepts and discusses the use of roscore , rosnode , and rosrun commandline tools. This tutorial introduces ROS services, and parameters as well as using the rosservice and rosparam commandline tools. If you use ROS fuerte or ealier distros where rqt isn't fully available, please see this page with this page that uses old rx based tools. This tutorial shows how to use rosed to make editing easier. This tutorial covers how to create and build msg and srv files as well as the rosmsg , rossrv and roscp commandline tools. This tutorial covers how to write a publisher and subscriber node in python.

ROS-I is supported by an international Consortium of industry and research members. This ros wiki of ROS development would be finalized when Clearpath Robotics took over support responsibilities for the PR2 in early

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. 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. However, it is possible to integrate ROS with real-time computing code. Software in the ROS Ecosystem [7] can be separated into three groups:. The majority of other packages are licensed under a variety of open-source licenses.

ROS implements several different styles of communication, including synchronous RPC-style communication over services , asynchronous streaming of data over topics , and storage of data on a Parameter Server. These are explained in greater detail in our Conceptual Overview. It's a difficult question to answer as the goal of ROS is not to be a framework with the most features. Instead, the primary goal of ROS is to support code reuse in robotics research and development. ROS is a distributed framework of processes aka Nodes that enables executables to be individually designed and loosely coupled at runtime. These processes can be grouped into Packages and Stacks , which can be easily shared and distributed.

These levels and concepts are summarized below and later sections go into each of these in greater detail. Note: since ROS Groovy these wiki pages describe concepts as they relate to the new catkin buildsystem. A package may contain ROS runtime processes nodes , a ROS-dependent library, datasets, configuration files, or anything else that is usefully organized together. Packages are the most atomic build item and release item in ROS.

As such, there is very little which is core to ROS, beyond the general structure within which programs must exist and communicate. Real-time operating systems RTOS. Playing messages back from a bag is largely the same as having the original nodes which produced the data in the ROS computation graph, making bags a useful tool for recording data to be used in later development. Current stable version: May Otherwise there might be some regex parsing of the whitelist that is a bit too restrictive. Tools Tools. Please see our section on Contributing for more information on how you can participate in the ROS community. Retrieved 23 January A node represents one process running the ROS graph.

From drivers to state-of-the-art algorithms, and with powerful developer tools, ROS has what you need for your next robotics project.
