Problem Expert

The Domain Expert module is responsible for maintaining the instances, predicates and goals of the PDDL problem.

The main class is plansys2::ProblemExpertNode, which is instantiated from problem_expert_node.cpp. plansys2::DomainExpertNode is a rclcpp_lifecycle::LifecycleNode, and in its configuration phase reads the model_file parameter, which contains the .pddl file from which to read the model.

The class responsible for maintaining this domain is plansys2::DomainExpert, which is independent of ROS2.

The Domain Expert does not change while active, accessing its functionality through ROS2 services. To facilitate the task of the application developer, an plansys2::DomainExpertClient class has been implemented that hides the complexity of handling ROS2 messages and services. Its API is similar to that of plansys2::DomainExpert, since both have to implement the plansys2::DomainExpertInterface interface.

Problem Expert

The Problem Expert module is responsible for maintaining the instances, predicates and goals of the PDDL problem.

The main class is plansys2::ProblemExpertNode, which is instantiated from ProblemExpertNode.cpp. plansys2::ProblemExpertNode is a rclcpp_lifecycle::LifecycleNode, but currently the functionality is in the active phase.

The class responsible for maintaining this problem instance is plansys2::ProblemExpert, which is independent of ROS2.

The Problem Expert is dynamic and volatile, accessing its functionality through ROS2 services. To facilitate the task of the application developer, an plansys2::ProblemExpertClient class has been implemented that hides the complexity of handling ROS2 messages and services. Its API is similar to that of plansys2::ProblemExpert, since both have to implement the plansys2::ProblemExpertInterface interface.

The Problem Expert instantiates a plansys2::DomainExpertClient, and every update query is verified against domain to check if it is valid.

Every update in the Problem, is notified publishing a std_msgs::msg::Empty in /problem_expert/update_notify. It helps other modules and applications to be aware of updates, being not necessary to do polling to check it.
