We have introduced the features and structure of ROS. Next we will begin to prepare for the strong ROS. On the wiki on the ROS official website, the tutorials for new users are very detailed. It is best to clarify all the tutorials for new users. This is the most basic thing for later development. Despite this, ROS is still difficult for beginners to get started. Here, I will summarize my learning history and serve as a reference for other new users.I

Imagine creating a library of wikis. Wiki sites contain content that users can create, delete, and modify interactively. Many wikis feature a simple, text-based markup language for creating content. Typically, these markup languages provide only a subset of the functionality available in HTML, but there is a simpler, clearer source format. For example, text that surrounds the asterisk is formatted as bold, and the underlined text is formatted as an un

You may have heard of weblogs, but wikis has no chance to enter your field of view. Both are examples of fast-growing so-called social software-a program that encourages connections with others and communities with good health. Blogs allows individuals to post their views and interests online, wikis is relatively concentrated on website preparation and regular editing through a professional community-these people can not only paste materials on the website, but also freely edit.
