33 Facts About Robot Operating System (ROS)

What is Robot Operating System (ROS)?

Robot Operating System (ROS) is a flexible framework for writing robot software. It provides tools, libraries, and conventions to simplify the task of creating complex and robust robot behavior across a wide variety of robotic platforms.

1. ROS is not an actual operating system. It's a middleware that 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.

2. ROS was originally developed in 2007. The development began at Stanford University and later continued at Willow Garage, a robotics research lab.

3. ROS is open-source. This means anyone can use, modify, and distribute the software for free. It encourages collaboration and sharing within the robotics community.

Key Components of ROS

Understanding the main components of ROS can help grasp its functionality and versatility.

4. Nodes are the fundamental building blocks. Each node is a process that performs computation. Nodes communicate with each other using topics, services, and actions.

5. Topics are used for message passing. Nodes can publish messages to a topic or subscribe to a topic to receive messages. This is useful for continuous data streams like sensor data.

6. Services provide a request/reply communication model. Unlike topics, services are used for tasks that require a response, such as querying the state of a robot or sending a command.

7. Actions are for long-running goals. They allow nodes to send a goal to another node and receive feedback on the progress, which is useful for tasks like navigation.

8. The ROS Master facilitates communication. It provides naming and registration services to the nodes in the ROS system, enabling them to find each other and communicate.

Popular Uses of ROS

ROS has found applications in various fields, from academic research to industrial automation.

9. ROS is widely used in academia. Many universities and research institutions use ROS for teaching and research in robotics.

10. ROS is used in autonomous vehicles. Companies developing self-driving cars often use ROS for prototyping and testing their algorithms.

11. ROS is popular in industrial automation. Factories use ROS to control robotic arms, conveyor belts, and other machinery, improving efficiency and precision.

12. ROS is used in healthcare robotics. Robots in hospitals and care facilities use ROS for tasks like patient monitoring, medication delivery, and surgery assistance.

ROS Versions and Distributions

ROS has multiple versions and distributions, each with its own features and improvements.

13. ROS 1 was the original version. It has been widely adopted and used for many years, with numerous packages and tools developed for it.

14. ROS 2 is the latest version. It addresses some of the limitations of ROS 1, such as real-time performance, security, and support for multiple robots.

15. ROS distributions are named after turtles. Each distribution has a unique name, such as "Melodic Morenia" or "Noetic Ninjemys," following a tradition of naming them after turtles.

16. ROS 2 uses DDS for communication. The Data Distribution Service (DDS) is a middleware protocol that provides real-time data exchange, making ROS 2 suitable for more demanding applications.

ROS Tools and Libraries

ROS comes with a variety of tools and libraries that simplify the development process.

17. RViz is a visualization tool. It allows users to visualize the state of the robot, sensor data, and other information in a 3D environment.

18. Gazebo is a simulation tool. It provides a realistic simulation environment for testing robots and algorithms without needing physical hardware.

19. rosbag is a data recording tool. It allows users to record and playback ROS message data, which is useful for debugging and analysis.

20. catkin is a build system. It helps manage the compilation and installation of ROS packages, making it easier to develop and share code.

21. MoveIt! is a motion planning library. It provides tools for planning and executing motions for robotic arms and other manipulators.
