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.

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.
