10.6 回顾

总结一下到目前为止我们接触过的一些命令：

• rospack = ros+pack(age) : provides information related to ROS packages

• rosstack = ros+stack : provides information related to ROS stacks

• roscd = ros+cd : changes directory to a ROS package or stack

• rosls = ros+ls : lists files in a ROS package

• roscp = ros+cp : copies files from/to a ROS package

• rosmsg = ros+msg : provides information related to ROS message definitions

• rossrv = ros+srv : provides information related to ROS service definitions

• rosmake = ros+make : makes (compiles) a ROS package

既然已经学习了如何创建ROS消息和服务，接下来就就将学习如何编写简单的发布器和订阅器(python) (c++).
