Publishers需要2到3个参数:topic type、topic name、queue size. minimal_publisher代码如下: #include <ros/ros.h> #include <std_msgs/Float64.h> int main(int argc, char **argv) { ros::init(argc, argv, "minimal_publisher"); ros::NodeHandle n; ros::Publisher my_publisher_object = n.adverti...
我们应该能看到从publisher和subscriber来的消息 (数字不断增大). 1.8 创造自己的package colcon使用REP 149中定义的package.xml规范(也支持格式format 2). colcon支持多种编译类型. 推荐的编译类型是ament_cmake和ament_python. 也支持纯cmakepackages.
