This article mainly explains "what is ROS". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is ROS".

1. What is ROS?

ROS (Robot Operating System) is an open source robot operating system that provides functions such as hardware abstraction, underlying device control, inter-process message communication and package management. ROS also provides tools and library files for writing, compiling, and running code.

Just like the concept of Android framework for developing upper-level mobile applications, you can also think of ROS as a "robot framework", which makes it easy for us to learn robotics without having to repeat wheels.

There are many robot frameworks like ROS in the industry, such as Player,YARP,Orocos and so on.

In terms of real-time performance, ROS is not a real-time framework, but the real-time code can be integrated into the ROS framework. For example, PR2 robots use pr2_etherCAT system to ensure the real-time performance of PR2.

2. What is the goal of ROS?

The goal of ROS is not to be the best, with the most versatile framework. On the contrary, the main goal of ROS is to support code reuse and improve efficiency in robot research and development.

The executable file (Node) of the ROS system can be designed and decoupled separately, which makes ROS a distributed framework. Because the package coupling of ROS is relatively small, it can be easily shared and distributed, which is also in line with the main goal of ROS-code reuse.

3. What systems does ROS support?

ROS currently runs only on machines based on the Unix platform, and ROS's software has been mainly tested on Ubuntu and Mac OS X.

However, ROS is open source, and the ROS community is also growing. At present, many developers are also working hard to provide system support for platforms such as Fedora,Gentoo,Arch Linux. I believe that the future development of ROS will be better and better.

Thank you for your reading, the above is the content of "what is ROS", after the study of this article, I believe you have a deeper understanding of what ROS is, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
