◆ calculateClosestObjectToPose() [1/2]

tl::expected<std::vector<ObjectWithDistance>, std::string> moveit_studio::behaviors::calculateClosestObjectToPose	(	const tf2_ros::Buffer &	buffer,
		const std::vector< GraspableObject > &	graspable_objects,
		const geometry_msgs::msg::PoseStamped &	pose
	)

◆ calculateClosestObjectToPose() [2/2]

tl::expected<std::vector<ObjectWithDistance>, std::string> moveit_studio::behaviors::calculateClosestObjectToPose	(	const tf2_ros::Buffer &	buffer,
		const std::vector< moveit_studio_vision_msgs::msg::GraspableObject > &	objects,
		const geometry_msgs::msg::PoseStamped &	pose
	)

Get the closest object to the provided pose.

Parameters

objects	Collection of GraspableObjects to evaluate.
pose	Pose to use for distance comparison.

Returns: If successful, returns a vector containing the input GraspableObjects sorted in ascending order by distance to the input pose. Returns a failure state if no qualifying object was found.

◆ clientMustBeRecreated() [1/2]

bool moveit_studio::behaviors::clientMustBeRecreated	(	const std::shared_ptr< rclcpp::ClientBase > &	client,
		const std::string_view	new_service_name
	)

inline

Compare a service client's current configuration to the desired new configuration to determine if the client needs to be recreated.

This checks two criteria:

Is the client a nullptr? This will be the case the first time this Behavior is ticked in a new Objective, so the client must be created in that case.
If the client already exists, does it communicate on a topic with the same name as the name provided through the input data port? If not, the client needs to be reinitialized to use the new topic.

This does NOT check if the client's QoS settings match the ones used by the server, because ServiceClientBehaviorBase always creates clients using the rmw_qos_profile_services_default QoS profile. Also, it is unlikely that a ROS 2 service server would use customized QoS settings.

Parameters

client	The service client to check
new_service_name	The new service name

Returns: True if the client must be recreated to satisfy the new configuration. False if the client's current configuration already satisfies the new configuration.

◆ clientMustBeRecreated() [2/2]

bool moveit_studio::behaviors::clientMustBeRecreated	(	const std::shared_ptr< rclcpp_action::ClientBase > &	client,
		const std::string_view	old_action_name,
		const std::string_view	new_action_name
	)

inline

Compare an action client's current configuration to the desired new configuration to determine if the client needs to be recreated.

This checks two criteria:

Is the client a nullptr? This will be the case the first time this Behavior is ticked in a new Objective, so the client must be created in that case.
If the client already exists, does it communicate with an action with the same name as the name provided through the input data port? If not, the client needs to be reinitialized to use the new action name.

This does NOT check if the client's QoS settings match the ones used by the server, because ActionClientBehaviorBase always creates clients using the default ROS 2 action client QoS profile. It is also very complex to retrieve the QoS settings for an action server (since it's composed of a collection of services and topics). In any case action clients are almost always created with default QoS settings (or at the very least we've never seen one that used non-default settings).

Parameters

client	The action client to check
new_action_name	The new action name

Returns: True if the client must be recreated to satisfy the new configuration. False if the client's current configuration already satisfies the new configuration.

◆ convertExpectedToOptional()

		const double	width,
		const double	height,
		const double	stride_distance
	)

Generates a zig-zag path for a robot end-effector to follow, to cover a given area.

Parameters

bottom_right_corner	The bottom right corner of the area to cover, with X pointing along the 'width' dimension and Y pointing along the 'height' dimension.

base_frame	Common fixed frame of reference between the two objects.
distance_threshold	Objects are considered dissimilar if their centroids are more than this distance away from each other.
orientation_threshold	Objects are considered dissimilar if the orientations of their centroids differ by this magnitude in radians.

Returns: If object similarity could be calculated without errors, returns true if the objects are similar and false if they are dissimilar. Returns an error message if the objects could not be compared successfully.

◆ maybe_error() [1/2]

template<typename... Args>

std::optional<std::string> moveit_studio::behaviors::maybe_error ( BT::Expected< Args >... args )

inline

Check if any of the provided inputs represent error states and, if so, return their error messages.

Parameters

args	One or more BT::Expecteds (i.e., results from getInput)

Returns: std::optional wrapping std::string. If all of the inputs in args have values, returns std::nullopt. If one or more of the inputs in args contains an error state instead of a value, return a string that contains the concatenated error messages of all inputs that did not contain a value.

◆ maybe_error() [2/2]

template<typename E , typename... Args>

constexpr std::optional<E> moveit_studio::behaviors::maybe_error ( tl::expected< Args, E >... args )

constexpr

Tests if any of the expected args passed in has an error.

This was adapted from fp's maybe_error function with a small modification.

Parameters

[in] The tl::expected<T, E> variables. All have to use the same error type.

Template Parameters

E	The error type
Args	The value types for the tl::expected<T, E> args

	)

inline

Helper function to register a behavior with the default constructor signature with a BT::BehaviorTreeFactory.

Parameters

factory	Register behaviors with this factory.
name	The name to use when registering this type of behavior. It is good practice to make this name match the name of the class (e.g., moveit_studio::behaviors::PlanMTCTask is registered as "PlanMTCTask").

Template Parameters

◆ registerBehavior() [2/2]

template<typename T >

void moveit_studio::behaviors::registerBehavior	(	BT::BehaviorTreeFactory &	factory,
		const std::string &	name,

	)

inline

Helper function to register a behavior derived from SharedResourcesNode with a BT::BehaviorTreeFactory.

Parameters

factory	Register behaviors with this factory.
name	The name to use when registering this type of behavior. It is good practice to make this name match the name of the class (e.g., moveit_studio::behaviors::PlanMTCTask is registered as "PlanMTCTask").
shared_resources	A shared_ptr to an instance of BehaviorContext, which will be provided when creating the behaviors registered by this function.

Template Parameters

T	Register a behavior of this type.

	)

Send a request through a service client for a moveit_msgs::srv::ServoCommandType service and block until a response is received or a timeout limit is reached.

Parameters

client	Service client to use
request	Service request message to send

Returns: tl::expected containing void if the service succeeds. Returns an error string if the wait duration exceeded kServiceResponseMaxWait. Returns an error string if the server reports that the service request did not succeed.

◆ shouldRecreatePublisher()

bool moveit_studio::behaviors::shouldRecreatePublisher	(	const std::shared_ptr< rclcpp::PublisherBase > &	publisher,
		const std::string_view	topic_name,
		const size_t	queue_size,
		const rclcpp::ReliabilityPolicy	reliability_policy
	)

inline

Compare a publisher's current configuration to the desired new configuration to determine if the publisher needs to be recreated.

This checks two criteria:

Is the publisher a nullptr? This will be the case the first time this Behavior is ticked in a new Objective, so the publisher must be created in that case.
If the publisher already exists, does it publish to the right topic? If not, the publisher needs to be reinitialized to use the new topic name.
If the publisher already exists, does its queue_size and reliability QoS settings match the new queue_size and reliability? If not, the publisher needs to be reinitialized with these new QoS settings.

Parameters

publisher	The existing publisher to check.
topic_name	The topic name for the new configuration.
queue_size	The queue size for the new configuration.
reliability_policy	The reliability policy for the new configuration

Returns: True if the publisher must be recreated, and false if the publisher's current configuration already satisfies the new configuration.

◆ shouldRecreateSubscriber()

template<typename MessageT >

bool moveit_studio::behaviors::shouldRecreateSubscriber	(	const std::shared_ptr< rclcpp::Subscription< MessageT >> &	subscriber,
		const std::string &	topic_name,
		const rclcpp::QoS &	publisher_qos
	)

Compare a subscriber's current configuration to the desired new configuration to determine if the subscriber needs to be recreated.

This checks three criteria:

Is the subscriber a nullptr? This will be the case the first time this Behavior is ticked in a new Objective, so the subscriber must be created in that case.
If the subscriber already exists, does it listen on the right topic? If not, the client needs to be reinitialized to use the new action name.
If the subscriber already exists, does it use the same reliability QoS setting as the publisher? If not, the subscriber needs to be reinitialized using the same reliability QoS setting as the publisher.

Parameters

subscriber	The existing subscriber to check.
topic_name	The topic name for the new configuration.
publisher_qos	The publisher's QoS for the new configuration.

Template Parameters

MessageT The ROS message type used to specialize this function.

Returns: True if the subscriber must be recreated, and false if the subscriber's current configuration already satisfies the new configuration.

◆ splitSolutionAtIndex()

tl::expected< std::vector< moveit_task_constructor_msgs::msg::Solution >, std::string > moveit_studio::behaviors::splitSolutionAtIndex	(	const moveit_task_constructor_msgs::msg::Solution	solution_in,
		const std::size_t	index
	)

Split an MTC Solution message in two by dividing its vector of subtrajectories at the specified index.

The subtrajectory at the index will go into the second output MTC Solution. The task IDs of the new solutions will be set to match the task ID of the input solution.

The start_scene field of each new solution will be set to a new empty moveit_msgs::msg::PlanningScene message, since the MTC ExecuteSolution MoveGroup capability actually does not use this initial scene state when executing the solution. This is an implementation compromise – while a more thorough approach would be to calculate a new start_scene for the second half of the split solution by applying each scene diff from the subtrajectories in the first half of the split solution to the start_scene from the original solution, we would need to create an instance of a MoveIt PlanningScene object to do that, which introduces a lot of extra overhead like retrieving the robot model and SRDF.

The sub_solution field of each new solution will be set to an empty vector of moveit_task_constructor_msgs::msg::SubSolution messages. This is another implementation compromise – since MTC apparently does not need the subsolutions to execute each of the overall solution's subtrajectories, and there isn't a clear way to associate these subsolutions with a subset of the subtrajectories, we skip the step of copying subsolutions in to the halves of the split solution.

Parameters

solution_in	Input MTC Solution message
index	The index where the subtrajectories will be split.

Returns: A tl::expected wrapping a vector of MTC solutions. If there is no error, the vector will contain two MTC Solution messages, where the first one contains the portion of the input Solution that was before the split index and the second one contains the remainder of the solution. Returns an InvalidArgument error if the index would be out of range for the vector of subtrajectories.

◆ startServo()

tl::expected< void, std::string > moveit_studio::behaviors::startServo ( std::shared_ptr< rclcpp::Client< std_srvs::srv::SetBool >> client )

Starts the servo node.

Returns: tl::expected containing void if validation succeeds. Returns an error message if the service call to start the servo server fails.

◆ stopServo()

tl::expected< void, std::string > moveit_studio::behaviors::stopServo ( std::shared_ptr< rclcpp::Client< std_srvs::srv::SetBool >> client )

Stops the servo node.

Returns: tl::expected containing void if validation succeeds. Returns an error message if the service call to stop the servo server fails.

◆ waitForPublisher()

tl::expected< rclcpp::TopicEndpointInfo, std::string > moveit_studio::behaviors::waitForPublisher	(	const std::shared_ptr< rclcpp::Node > &	node,
		const std::string &	topic_name
	)

Waits for a publisher to be advertised on the provided topic, and gets the TopicEndpointInfo for the publisher once it appears.

If multiple publishers are found on the same topic, this function just returns the TopicEndpointInfo for the first one in the order they were reported by the node. If multiple publishers advertise on the same topic with different reliability QoS settings the Behavior will only receive messages from the ones whose settings match the first publisher in the list. This situation will only happen if the publishers have been incorrectly configured, so this is not handled by this Behavior.

Parameters

node	Node used to retrieve publisher info.
topic_name	Name of the topic where we expect the publisher to advertise.

Returns: If one or more publishers were found on the topic, returns the TopicEndpointInfo for the first publisher that was found. If no publishers were found on the topic before the timeout elapsed, return an error result.
