怎样终止正在进行的导航navigation
how to cancel a navigation goal or how to stop current navigation?
导航时，取消当前目标点或者暂停导航是一个常见的问题
经过查阅资料．发现仅用如下一条指令即可另导航停止，小车停止:
rostopic pub /move_base/cancel actionlib_msgs/GoalID -- {}
或者
ros::Publisher cancle_pub_ = nh_.advertise<actionlib_msgs::GoalID>("move_base/cancel",1);
actionlib_msgs::GoalID first_goal;
cancle_pub_.publish(first_goal);
