Developments — During World War II the first mobile robots emerged as a result of technical advances on a number of relatively new research fields like computer science and cybernetics. They were mostly flying bombs. Examples are smart bombs that only detonate within a certain range of the target, the use of guiding systems and radar control.
Navigation Standard Robot Messages Years of community discussion and development have led to a set of standard message formats that cover most of the common use cases in robotics.
There are message definitions for geometric concepts Mobile robot localization poses, transforms, and vectors; for sensors like cameras, IMUs and lasers; and for navigation data like odometry, paths, and maps; among many others.
By using these standard messages in your application, your code will interoperate seamlessly with the rest of Mobile robot localization ROS ecosystem, from development tools to libraries of capabilities. Robot Geometry Library A common challenge in many robotics projects is keeping track of where different parts of the robot are with respect to each other.
For example, if you want to combine data from a camera with data from a laser, you need to know where each sensor is, in some common frame of reference. This issue is especially important for humanoid robots with many moving parts.
We address this problem in ROS with the tf transform library, which will keep track of where everything is in your robot system. Designed with efficiency in mind, the tf library has been used to manage coordinate transform data for robots with more than one hundred degrees of freedom and update rates of hundreds of Hertz.
The tf library allows you to define both static transforms, such as a camera that is fixed to a mobile base, and dynamic transforms, such as a joint in a robot arm. You can transform sensor data between any pair of coordinate frames in the system.
The tf library handles the fact that the producers and consumers of this information may be distributed across the network, and the fact that the information is updated at varying rates.
Robot Description Language Another common robotics problem that ROS solves for you is how to describe your robot in a machine-readable way. The format for describing your robot in ROS is URDF Unified Robot Description Formatwhich consists of an XML document in which you describe the physical properties of your robot, from the lengths of limbs and sizes of wheels to the locations of sensors and the visual appearance of each part of the robot.
Once defined in this way, your robot can be easily used with the tf library, rendered in three dimensions for nice visualizationsand used with simulators and motion planners.

SLAM stands for Simultaneous Localization and Mapping and one way to understand it is to imagine yourself entering an unfamiliar building for the first time.|
ROS provides actions for this purpose. Actions are like services except they can report progress before returning the final response, and they can be preempted by the caller.
So, for example, you can instruct your robot to navigate to some location, monitor its progress as it attempts to get there, stop or redirect it along the way, and be told when it has succeeded or failed. An action is a powerful concept that is used throughout the ROS ecosystem. Diagnostics ROS provides a standard way to produce, collect, and aggregate diagnostics about your robot so that, at a glance, you can quickly see the state of your robot and determine how to address issues as they arise.
Pose Estimation, Localization, and Navigation ROS also provides some "batteries included" capabilities that help you get started on your robotics project. There are ROS packages that solve basic robotics problems like pose estimationlocalization in a mapbuilding a mapand even mobile navigation.
Whether you are an engineer looking to do some rapid research and development, a robotics researcher wanting to get your research done in a timely fashion, or a hobbyist looking to learn more about robotics, these out-of-the-box capabilities will help you do more, with less effort.
Tools One of the strongest features of ROS is the powerful development toolset. These tools support introspecting, debugging, plotting, and visualizing the state of the system being developed. The ROS tools take advantage of this introspection capability through an extensive collection of graphical and command line utilities that simplify development and debugging.
Command-Line Tools Do you spend all of your time remotely logged into a robot? All core functionality and introspection tools are accessible via one of our more than 45 command line tools.
There are commands for launching groups of nodes; introspecting topics, services, and actions; recording and playing back data; and a host of other situations.
If you prefer to use graphical tools, rviz and rqt provide similar and extended functionality.
It also uses information from the tf library to show all of the sensor data in a common coordinate frame of your choice, together with a three-dimensional rendering of your robot.Core Components. Communications Infrastructure | Robot-Specific Features | Tools.
While we cannot provide an exhaustive list of what is in the ROS ecosystem, we can identify some of the core parts of ROS and talk about their functionality, technical specifications, and quality in order to give you a better idea of what ROS can contribute to your project.
