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...

source过环境后, 我们可以运行通过colcon编译的executables. 让我们从例子中运行一个subscriber节点 (node): ros2 run examples_rclcpp_minimal_subscriber subscriber_member_function 在另一个terminal, 运行publisher 节点 (不要忘记source设置脚本): ros2 run examples_rclcpp_minimal_publisher publisher_member_function...

最后就是main函数啦,先初始化rclpy,再创建MinimalPublisher,进入自旋锁,当退出锁时,就会关闭节点结束啦。 完成以上发布者的代码后,功能包里还有一些内容需要设置。 设置依赖项 打开功能包的package.xml文件,先把这些基础信息填写好: <description>Examples of minimal publisher/subscriber using rclpy</description> <mai...
Although the reason could have been how reliable publisher works when its history is configured as KEEP_LAST, finally this is not the case. Using netstat, I discovered that the kernel was discarding UDP packets. The socket's buffer must be getting full because the subscriber is not draining ...
