# `PIBot_ROS`说明
> 更新:`zhanli` 2023-12-13
### 一、`PIBot_ROS`简介
`PIBot_ROS`本质上一个封装功能非常完善的功能包,其内部添加了许多已经整合好了功能,更加便于使用。
- `ros_package` : 内置了许多算法的功能包的压缩包
- `pypibot` : `pibot`相关的python支持功能
- `pibot_upstart` : 未知待补充
- `ros_ws` : `ROS`的工作空间
##### 1.1 `ros_ws`的目录结构
下图中`catkin_workspcae`对应即是`ros_ws`文件夹。其下面一般具有`src`、`build`、`devel`等功能。
<img src="http://logzhan.ticp.io:30000/logzhan/PictureHost/raw/branch/main/RobotKernal-UESTC/ROS_File_Structure.png" style="zoom: 50%;" />
上述文件的结构和说明如下面的文档所示:
```shell
WorkSpace --- 自定义的工作空间
|--- build:编译空间用于存放CMake和catkin的缓存信息、配置信息和其他中间文件。
|--- devel:开发空间,用于存放编译后生成的目标文件,包括头文件、动态&静态链接库、可执行文件等。
|--- src: 源码
|-- package功能包(ROS基本单元)包含多个节点、库与配置文件,包名所有字母小写,只能由字母、数字与下划线组成
|-- CMakeLists.txt 配置编译规则,比如源文件、依赖项、目标文件
|-- package.xml 包信息,比如:包名、版本、作者、依赖项...(以前版本是 manifest.xml)
|-- scripts 存储python文件
|-- src 存储C++源文件
|-- include 头文件
|-- msg 消息通信格式文件
|-- srv 服务通信格式文件
|-- action 动作格式文件
|-- launch 可一次性运行多个节点
|-- config 配置信息
|-- CMakeLists.txt: 编译的基本配置
```
##### 1.2 `package.xml`
如上图所示ROS的基本功能都是通过包(`package`)组织的。该文件定义有关软件包的属性例如软件包名称版本号作者维护者以及对其他catkin软件包的依赖性。请注意该概念类似于旧版` rosbuild` 构建系统中使用的`manifest.xml`文件。
`package.xml`的部分内容如下图所示, 推测ROS系统通过`package.xml`的内容识别对应包的功能命令。
```xml
<?xml version="1.0"?>
<!-- 格式: 以前是 1推荐使用格式 2 -->
<package format="2">
<!-- 包名 -->
<name>demo01_hello_vscode</name>
<!-- 版本 -->
<version>0.0.0</version>
<!-- 描述信息 -->
...
</package>
```

`PIBot_ROS`的文件解压或重新命名可以按照个人习惯即可,这里以解压后命名为`pibot_ros`为例,介绍命令启动导航

# ROS基础笔记
##### 1.1 `ros::Rate`的用法
`ros::Rate` 是ROS中用于控制循环频率的工具。在你提到的代码中`ros::Rate loop_rate(10);` 创建了一个 `ros::Rate` 对象,其目的是控制循环的频率。
```c++
ros::Rate loop_rate(10); // 设置事件循环的频率为10Hz
while (ros::ok()) {
// 处理其他任务,这个地方不能处理过于耗时的操作
ros::spinOnce(); // 处理一次事件循环
loop_rate.sleep(); // 使节点等待足够的时间以达到设定的频率
}
```

# ROS基础之基础命令
> https://blog.csdn.net/sinat_16643223/article/details/113935412
## 一、常用命令
##### 1.1 `catkin_make`编译命令
```shell
# 进入工作空间
cd ros_ws
# 编译
catkin_make
```
我们在使用ROS的时候经常会使用`catkin_make`命令,但我们时常会有疑惑`cakin_make`和`make`的区别。我们可以简单理解为`catkin_make`是`make`的扩展它更加适合ROS相关的编译。
`Catkin` 是 ROS 中使用的构建系统,而 `CMake ``Catkin` 的底层构建系统。具体而言,`Catkin` 使用 `CMake` 作为其构建系统的基础,它对 `CMake` 进行了扩展,以适应 ROS 的特殊需求和机器人软件包的组织。
以下是它们之间的关系:
1. **`CMake`** `CMake` 是一个跨平台的开源构建系统,它使用一种基于文本的 DSL领域特定语言来描述软件项目的构建过程。`CMake` 生成适用于目标平台的构建系统文件,例如 `Makefile` 或` Visual Studio` 项目文件。
2. **`Catkin`** Catkin 是 ROS 特有的构建系统,构建在 `CMake` 之上。`Catkin` 扩展了 `CMake`,以便更好地支持 `ROS` 软件包的组织和构建。`Catkin` 引入了一些 ROS 特有的概念例如工作空间workspace、软件包package、消息和服务生成等。
在一个 `ROS` 工作空间中,通常会包含一个或多个` Catkin` 软件包,每个软件包都包含一个 `CMakeLists.txt` 文件,其中定义了软件包的构建规则、依赖关系等。总的来说,**Catkin 通过扩展 `CMake`,提供了一个更高级别的构建系统,使得在 ROS 中更容易管理和构建机器人软件项目**。 CMake 提供了通用的构建系统功能,而 `Catkin` 在其基础上添加了 `ROS` 特有的工具和概念。
##### 1.2 `roslaunch`命令
```shell
roslaunch pibot_navigation nav.launch
```
在命令`roslaunch pibot_navigation nav.launch`中,`roslaunch`本质上是一个可执行文件。`pibot_navigation `是工作空间`workspace`中软件包。`ros_launch`是通过软件包下面的`package.xml`识别出功能包。`nav.launch`是`pibot_navigation`下面`launch`文件夹下的一个`nav.launch`文件,其本质是个一个`xml`文件,描述了要启动的节点以及对应要传递的参数。
