ROS 发布者程序，控制小龟行走

#include <ros/ros.h>
#include <geometry_msgs/Twist.h>
#include <stdlib.h>

int main ( int argc , char ** argv ) {

ros::init (argc, argv, "publish_velocity") ;
ros::NodeHandle nh ;

ros::Publisher pub = nh.advertise <geometry_msgs::Twist >(
"turtle1/cmd_vel" , 1000 ) ;

srand(time(0));
ROS_INFO_STREAM( "Sending random velocity  : ") ;
ros::Rate rate(2) ;
while (ros::ok()) {

geometry_msgs::Twist msg;
msg.linear.x = double (rand()) / double (RAND_MAX);
msg.angular.z = 2*double ( rand())/double (RAND_MAX)-1;

pub.publish ( msg ) ;

// Send a message to rosout with the details .
ROS_INFO_STREAM( "Sending random velocity command : "
<< " linear=" << msg.linear.x
<< " angular=" << msg.angular.z) ;

// Wait untilit's time for another iterationet.
rate.sleep () ;
}
}

ros::Publisher pub = nh.advertise <geometry_msgs::Twist >(
"turtle1/cmd_vel" , 1000 ) ; 创建一个发布者

发布消息：

pub.publish ( msg ) ;

一.CMakeList.txt 中增加如下：

find_package(catkin REQUIRED COMPONENTS roscpp geometry_msgs)

catkin_package()

include_directories(include ${catkin_INCLUDE_DIRS})

add_executable(pubvel pubvel.cpp)
target_link_libraries(pubvel ${catkin_LIBRARIES})

二.package.xml 配置增加如下:

 <build_depend>roscpp</build_depend>
  <exec_depend>roscpp</exec_depend>
  <build_depend>geometry_msgs</build_depend>
  <exec_depend>geometry_msgs</exec_depend>

三。运行程序：
