Constants

const SubtypeName = resource.SubtypeName("movement_sensor")

SubtypeName is a constant that identifies the component resource subtype string "movement_sensor".

Variables

var (
	// ErrMethodUnimplementedAccuracy returns error if the Accuracy method is unimplemented.
	ErrMethodUnimplementedAccuracy = errors.New("Accuracy Unimplemented")
	// ErrMethodUnimplementedPosition returns error if the Position method is unimplemented.
	ErrMethodUnimplementedPosition = errors.New("Position Unimplemented")
	// ErrMethodUnimplementedOrientation returns error if the Orientation method is unimplemented.
	ErrMethodUnimplementedOrientation = errors.New("Orientation Unimplemented")
	// ErrMethodUnimplementedLinearVelocity returns error if the LinearVelocity method is unimplemented.
	ErrMethodUnimplementedLinearVelocity = errors.New("LinearVelocity Unimplemented")
	// ErrMethodUnimplementedAngularVelocity returns error if the AngularVelocity method is unimplemented.
	ErrMethodUnimplementedAngularVelocity = errors.New("AngularVelocity Unimplemented")
	// ErrMethodUnimplementedCompassHeading returns error if the CompassHeading method is unimplemented.

)

var Subtype = resource.NewSubtype(
	resource.ResourceNamespaceRDK,
	resource.ResourceTypeComponent,
	SubtypeName,
)

Subtype is a constant that identifies the component resource subtype.

Functions

func DependencyTypeError

func DependencyTypeError(name string, actual interface{}) error

DependencyTypeError is used when a resource doesn't implement the expected interface.

func GetHeading

func GetHeading(gps1, gps2 *geo.Point, yawOffset float64) (float64, float64, float64)

GetHeading calculates bearing and absolute heading angles given 2 MovementSensor coordinates 0 degrees indicate North, 90 degrees indicate East and so on.

func Named

func Named(name string) resource.Name

Named is a helper for getting the named MovementSensor's typed resource name.

func NamesFromRobot

func NamesFromRobot(r robot.Robot) []string

NamesFromRobot is a helper for getting all MovementSensor names from the given Robot.

func NewServer

func NewServer(s subtype.Service) pb.MovementSensorServiceServer

NewServer constructs an MovementSensor gRPC service subtypeServer.

func NewUnimplementedInterfaceError

func NewUnimplementedInterfaceError(actual interface{}) error

NewUnimplementedInterfaceError is used when there is a failed interface check.

func Readings

func Readings(ctx context.Context, g MovementSensor, extra map[string]interface{}) (map[string]interface{}, error)

Readings is a helper for getting all readings from a MovementSensor.

func WrapWithReconfigurable

func WrapWithReconfigurable(r interface{}, name resource.Name) (resource.Reconfigurable, error)

WrapWithReconfigurable - if MovementSensor is already a reconfigurableMovementSensor, then nothing is done. Otherwise wraps in a Reconfigurable.

Types

type LastError

type LastError struct {
	// contains filtered or unexported fields
}

LastError is an object that stores the most recent error.

func (*LastError) Get

func (le *LastError) Get() error

Get returns the most-recently-stored error, and sets the stored error to nil.

func (*LastError) Set

func (le *LastError) Set(err error)

Set stores an error to be retrieved later.

type MovementSensor

type MovementSensor interface {
	Position(ctx context.Context, extra map[string]interface{}) (*geo.Point, float64, error)                // (lat, long), altitude (mm)
	LinearVelocity(ctx context.Context, extra map[string]interface{}) (r3.Vector, error)                    // mm / sec
	AngularVelocity(ctx context.Context, extra map[string]interface{}) (spatialmath.AngularVelocity, error) // radians / sec
	LinearAcceleration(ctx context.Context, extra map[string]interface{}) (r3.Vector, error)
	CompassHeading(ctx context.Context, extra map[string]interface{}) (float64, error) // [0->360)
	Orientation(ctx context.Context, extra map[string]interface{}) (spatialmath.Orientation, error)
	Properties(ctx context.Context, extra map[string]interface{}) (*Properties, error)
	Accuracy(ctx context.Context, extra map[string]interface{}) (map[string]float32, error) // in mm
	generic.Generic
	sensor.Sensor
}

A MovementSensor reports information about the robot's direction, position and speed.

func FromDependencies

func FromDependencies(deps registry.Dependencies, name string) (MovementSensor, error)

FromDependencies is a helper for getting the named movementsensor from a collection of dependencies.

func FromRobot

func FromRobot(r robot.Robot, name string) (MovementSensor, error)

FromRobot is a helper for getting the named MovementSensor from the given Robot.

func NewClientFromConn

func NewClientFromConn(ctx context.Context, conn rpc.ClientConn, name string, logger golog.Logger) MovementSensor

NewClientFromConn constructs a new Client from connection passed in.

type Properties

type Properties pb.GetPropertiesResponse

Properties tells you what a MovementSensor supports.
