Похожий вопрос остался без ответа: Ошибка в ROS: Controller Spawner не удалось найти ожидаемый интерфейс ROS controller_manager
У меня есть рабочее пространство ROS с файлом запускав прошлый раз все работало нормальноОн запускает симулятор Gazebo, несколько узлов ROS, робота и RVIZ.Но сейчас это не удается.это просто запирает и умирает.Я не делал никаких изменений.Прошло несколько месяцев с момента моего последнего запуска ....
Вот сообщение об ошибке, но я не уверен, является ли это проблемой или нет:
[ОШИБКА] [1559523160.995762178]: GazeboRosControlPlugin отсутствует при использовании DefaultRobotHWSim, по умолчанию true.Этот параметр предполагает, что у вас есть старый пакет со старой реализацией DefaultRobotHWSim, где robotNamespace не учитывается и вместо него используются абсолютные пути.Если вы не хотите исправлять эту проблему в старом пакете, просто установите значение true.
Он говорит, что по умолчанию имеет значение true, но предлагает установить для legacyModeNS значение true.Я попробовал это.Я добавил элемент legacyModeNS к элементу.Кажется, это не имеет никакого эффекта.
Вот результат запуска файла запуска.Я не уверен, как быть более конкретным.
