.. cpp:member:: string name

	Optional node name, usually a station name.
	
.. cpp:member:: Vector2d position
	
	2D (x, y) map position, see :ref:`math.Vector2d`.
	
.. cpp:member:: Vector3d offset
	
	3D (x, y, yaw) pose offset relative to parent, see :ref:`math.Vector3d`.
	If parent is a :ref:`pilot.MapStation` the offset is relative to its orientation.
	
.. cpp:member:: set<drive_flags_e> drive_flags
	
	A set of drive flags for this node, see :ref:`pilot.drive_flags_e`.
