rospy包含的功能与roscpp相似,都有关于node、topic、service、param、time相关的操作。 但同时rospy和roscpp也有一些区别: rospy没有一个NodeHandle,像创建publisher、subscriber等操作都被直接封装成了rospy中的函数或类,调用起来简单直观。

The line import rospy imports the rospy module necessary for all ROS nodes in Python. The line from pkg_name.util import HelloGoodbye imports the class HelloGoodbye defined in the file pkg_name/util.py. Note that you can also include modules provided by other packages, if you specify the dependency in CMakeLists.txt and package.xml.

3. Update package.xml and CMakeLists.txt. Open the package.xml file and write the below lines. If you put the rospy dependency when you create the ROS package, you should already have into the file the rospy build depend and run depend. Otherwise, put all the below lines into the package.xml: <build_depend> rospy</build_depend>

In ROS1, for Cpp you use roscpp, and for Python, rospy. Both libraries are completely independent and built from scratch. It means that the API is not necessarily the same between roscpp and rospy, and some features are developed for one, and not the other. ROS2 has more layers. There is only one base library, named rcl, and implemented in C.

In the CMakeLists.txt, you have to add message_generation and std_msgs into the find_package(), so it becomes find_package(catkin REQUIRED message_generation std_msgs). After that you have to uncomment the add_message_files() part and add my_file.msg in it and finally uncomment the generate_messages() part. Open CmakeLists.txt, add message_generation to the list of COMPONENTS as follows: find_package(catkin REQUIRED COMPONENTS roscpp rospy std_msgs message_generation ) Export the message runtime dependency:
