ROS - “hello world!”

最简单的hello world基于 Groovy 和 Ubuntu 12.04 LTS.
step 1 creat package

catkin_create_pkg hello std_msgs roscpp rospy

step 2 modify CMakeLists.txt-only 2 places

add_executable(hello src/hello.cpp)target_link_libraries(hello ${catkin_LIBRARIES})

step 3 using ROS_INFO print the message in the hello.cpp

#include "ros/ros.h"#include "std_msgs/String.h"using namespace ros;int main(int argc, char **argv){  ros::Time::init();  ros::init(argc, argv, "hello");  ros::Rate loop_rate(10);  while (ros::ok())  {    ROS_INFO("%s", "hello world !");    ros::spinOnce();    loop_rate.sleep();  }  return 0;}
