Wheel

Mapped https://mapped.com/schema/mapped/1.0/core#Wheel

A wheel of a vehicle or mobile robot, identified on the chassis by its side and axle rather than by a fixed corner name so that vehicles with more than two axles are expressible. Its rolling motion is a Revolute_Joint; rollingRadius converts odometry travel into angular displacement.

Properties

Property	Type	Required	Default	Description
wheelAxleIndex	integer			Zero-based index of the axle the wheel is mounted on, counting from the front of the vehicle in the direction of forward travel.
wheelSide	string			Which side of the chassis the wheel is mounted on, viewed along the direction of forward travel: LEFT, RIGHT or CENTER. CENTER covers a single steered or castor wheel on the centreline.

exactType is always Wheel.

Inherited properties (28)

Property	Type	Required	Default	Description
assetLifecycleState	string			Refers to the various phases an asset undergoes from its initial acquisition to its eventual disposal
assetTrackingID	string			The ID of the device in the asset tracking system.
connectedDataSourceId	string			The id of the origin data source of an entity. This id is already a part of mappingKey but important for faster query.
connectorIds	Array<string>			The ids of the connectors associated with the entity.
dateCreated	dateTime			Datetime when it is created.
dateInstalled	dateTime			The date of installation or change out occurred.
dateUpdated	dateTime			Datetime when it is updated last time.
description	string
designLife	duration			The expected design life duration of an asset or component, expressed as a time duration.
enrichmentSourceConnectorId	string			The id of the source connector with which the vertex, whether it's a property bag or a derived entity, is associated.
expectsContinuousFlow	boolean			Expected to have continuous flow
firmwareVersion	string			Firmware version
flowCapacity	float			Indicates the maximum flow rate that a meter is capable of measuring accurately, typically specified in terms of volume per unit time or in pipe diameter
frameGeometry	string			Two-dimensional geometry of the entity expressed in declared coordinate frames, one entry per frame. Distinguished from geoshape, which is always CRS84 longitude/latitude; a frame referenced here may be an arbitrary local frame with no relationship to the Earth. Each entry conforms to the mapped.frame_geometry complex value schema and names its frame by id.
geoshape	Object
id	string	Yes		A globally unique ID in Mapped services.
inletPipeDiameter	float			Diameter of the inlet pipe of the meter
isVirtual	boolean		false	If this is true, the corresponding entity is virtual, meaning it doesn't exist in the real world but fabricated in the Mapped's system.
locationName	string			The name of the location where the entity is located.
mappingKey	string			The origin of the entity. More detailed definition is available at here.
name	string
organizationId	string	Yes		The id of the organization that owns the entity.
outletPipeDiameter	float			Diameter of the inlet pipe of the meter
seeAlso	string
serialNumber	string			A serial number is a unique identifier assigned incrementally or sequentially to an item
serviceLife	duration			The actual service life duration of an asset or component, expressed as a time duration.
systemType	Array<Object>			A system type of the system the entity is associated.
type	Array<Object>	Yes		The entity's types or classes. The types are determined within the class hierarchy. This is an stringified alias for rdf:type.

Relationships

Relationship	Targets	Inverse	Cardinality	Notes
rollingRadius	LengthQuantity		0..1	transitive, canonical Effective rolling radius of the wheel, used to convert odometry travel distance into angular displacement. A kinematic radius, which is not necessarily the largest radius of the rendered mesh and changes with load and wear.

hasHeartbeat	Heartbeat	isHeartbeatOf	0..1	transitive, canonical A point that represents the heartbeat of the data source such as a device or a connector which is the source of the corresponding Point.
hasIdentity	Identity		0..*	transitive, canonical
hasJoint	Kinematic_Joint	isJointOf	0..*	transitive, canonical The kinematic joints of an assembly. The joint vertex carries the axis and limits; the moving and fixed sides are named by hasJointChild and hasJointParent.
