Detailed Description

Requests a set of named points from the user by switching the view and displaying a sequence of prompts in the UI.

The list of point prompts can either contain a single element, meaning the same prompt is displayed for each requested point, or it can be the same size as the list of point names, meaning a different prompt is displayed for each point. The output is a list of stamped points, whose X and Y coordinates are normalized pixel coordinates in the range [0..1]. The requested name of each point is contained in the frame ID of its header.

Data Port Name	Port Type	Object Type
view_name	Input	std::string
point_names	Input	std::vector<std::string>
point_prompts	Input	std::vector<std::string>
pixel_coords	Output	std::vector<geometry_msgs::msg::PointStamped>

Constructor & Destructor Documentation

◆ GetPointsFromUser() [1/2]

moveit_studio::behaviors::GetPointsFromUser::GetPointsFromUser	(	const std::string &	name,
		const BT::NodeConfiguration &	config,
		const std::shared_ptr< BehaviorContext > &	shared_resources
	)

explicit

Construct a new GetPointsFromUser object.

Parameters

name	See SharedResourcesNode
config	See SharedResourcesNode
shared_resources	See SharedResourcesNode

◆ GetPointsFromUser() [2/2]

moveit_studio::behaviors::GetPointsFromUser::GetPointsFromUser	(	const std::string &	name,
		const BT::NodeConfiguration &	config,
		const std::shared_ptr< BehaviorContext > &	shared_resources,
		std::unique_ptr< ClientInterfaceBase< RequestPointsFromUser >>	client_interface
	)

explicit

Alternate constructor which can use an existing ClientInterfaceBase to support testing with a mock service client interface.

Parameters

name	See SharedResourcesNode
config	See SharedResourcesNode
shared_resources	See SharedResourcesNode
client_interface	unique_ptr to an instance of a class derived from ClientInterfaceBase. The Behavior will take ownership of the unique_ptr in this constructor.
