除了上一节“操作系统进程”中 “执行”小节的内容之外,在其中包含 ROS 节点的进程可能还需要考虑其他要素,例如: ● “软件包名 + 可执行文件名”而不是“可执行文件名 + PATH”(即ros2 run等效命令) ● ROS特定的环境变量(例如ROS_DOMAIN_ID、RMW_IMPLEMENTATION、控制台输出格式等) ● ROS 特定的命令行参数...
If the system load on a single computer exceeds a certain threshold an orchestration entity can trigger the following steps: pause all nodes through the life cycle interface, shutdown a specific node, spawning the node on a separate machine and passing the same configuration / parameters, and on...
