Main Robot Programming Takeaways: Robotics involves designing, constructing, and operating intelligent machines called robots. Step 3. Joint names in tags in the URDF must be compatible with the controller's configuration. The bridge provided with the prebuilt ROS 2 binaries includes support for common ROS interfaces (messages/services), such as the interface packages listed in the ros2/common_interfaces repository and tf2_msgs . WebSo, ROS2 comes with a lot of useful command line tools. Call the service by specifying the service name, service type, and the message data in yaml format: ros2 service call /spawn turtlesim/srv/Spawn "{x: 2, y: 2, theta: 0.0, name: 'tortise'}" The service returns the name of the turtle that was added to the playfield. epoll Linux IO select/poll select/poll epoll , epoll epoll select/poll epoll IO , epoll LT(level triggered) ET(edge-triggered)LT select/poll ET epoll epoll ET , LT ETN epoll select epoll, int epoll_create(int size) //epollsizesizeepoll, int epoll_ctl(int epfd, int op, int fd, struct epoll_event *event) // epoll //epfdepollepoll_create //op3 EPOLL_CTL_ADD//(fdepfd) EPOLL_CTL_MOD//(fd) EPOLL_CTL_DEL//(epfdfd) //fd //eventevent struct epoll_event { __uint32_t events; //Epoll events epoll_data_t data; //User data variable }; //eventsEPOLLIN()google, int epoll_wait(int epfd, struct epoll_event * events, int maxevents, int timeout) N, epoll 1 epoll_create Linux 2 listener 3 epoll_wait 4 epoll , int pipe(int fd[2]) , fd[0] fd[1] , 1Linuxsocket 2Linux C 3C UDP 4Cepoll 53UNIXTCP 6LinuxI/Oepoll, Zanerogl: Learn more.
