Get Node Reference VI

Owning Palette: Directed Graph Map VIs

Requires: Robotics Module

Returns a reference to the map node you specify.

You can wire the node reference this VI returns to the Path Planning VIs to specify the current or goal position of a robot navigating through a map.

Example

	map reference in is a reference to the map that represents the robot environment. Use the Create Directed Graph Map VI to generate this LabVIEW class object.
	name specifies the name of the map node.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	map reference out is a reference to the map that represents the robot environment. You can wire this output to other Path Planning VIs.
	node reference contains a reference to the map node with the name you specify. You can wire this output to the Path Planning VIs.
	found? indicates whether the map defines the position of the node you specify. If the map does not define the node, LabVIEW does not return an error.
	error out contains error information. This output provides standard error out functionality.

Example

Refer to the Astar on Voronoi.lvproj in the labview\examples\robotics\Path Planning\Astar\Astar on Voronoi Graph directory for an example of using the Get Node Reference VI.
