Public Member Functions

 IR_base (short dfc, DEGREE forward, DEGREE rotate, IOLINE c, IR_TYPE ir, uint8 subclass=0)
short value (void)
 Provide emulated value. Distance from object in millimeterss.

void WSwrite (void)
 Write object to shared memory.

void status (JAUS_STATE istat)
 Set status of component.

void scanner (oServo *s)
 Provide a servo for a scanner type sensor mount.

bool scanner (void)
 Returns wether base is a scanner type or fixed.

void angle (DEGREE d)
 Sets the angle that the base is facing relative to _face; i.e., if mounted 20 degrees from center, then 0 is 20 degrees from center. If defined with a servo, then will turn the base to that direction.

DEGREE angle (void)
 return angle at which scanner is pointed relative to local center (_face).

FIXED_RADIAN bearing (void)
 Returns current facing of sensor taking into account scanner rotation (FIXED).

int maximum_sensor_range (void)
 Returns the maximum sensor range in millimetres.

void maximum_sensor_range (int msr)
 Set the maximum range of the sensor.

bool locked (void)
 Returns whether the sensor is locked.

void locked (bool l)

Data Fields

int _DFC
 Distance from center of platform (MILLIMETERS).

FIXED_RADIAN F_face
 where the IR is facing 0 is forward + is counterclock-wise.

FIXED_RADIAN F_orient
 Position (radians) around the robot from defined center position (0=forward).

Detailed Description

A class to locate an IR on a robot.


Constructor & Destructor Documentation

IR_base short  dfc,
DEGREE  forward,
DEGREE  rotate,
IOLINE  c,
IR_TYPE  ir,
uint8  subclass = 0
 

Parameters:
dfc IR distance from center of vehicle.
forward facing direction (0 is robot's forward; counterclockwise)
rotate how many degrees you must rotate around vehicle center to locate sensor.
c channel on A/D port.
ir type of IR


Member Function Documentation

DEGREE angle void   )  [inherited]
 

return angle at which scanner is pointed relative to local center (_face).

void angle DEGREE  d  )  [inherited]
 

Sets the angle that the base is facing relative to _face; i.e., if mounted 20 degrees from center, then 0 is 20 degrees from center. If defined with a servo, then will turn the base to that direction.

FIXED_RADIAN bearing void   )  [inherited]
 

Returns current facing of sensor taking into account scanner rotation (FIXED).

bearing is Absolute direction of sensor with respect to robot's forward as 0 degrees; it incorporates the facing of sensor. To get the bearing with respect to the world system, you must add the robot's current heading; i.e., bearing() + angle()

void locked bool  l  )  [inherited]
 

bool locked void   )  [inherited]
 

Returns whether the sensor is locked.

This is a locking mechanism if you wish to allocate a sensor for a private use and cannot be allocated by another call to Object_List::bearing until it is unlocked.

void maximum_sensor_range int  msr  )  [inherited]
 

Set the maximum range of the sensor.

int maximum_sensor_range void   )  [inherited]
 

Returns the maximum sensor range in millimetres.

maximum sensor_range declared below so it can be initialized low level, but returns a low level so a generic <sensor_base*> can access maximum sensor range without knowing its type.

bool scanner void   )  [inherited]
 

Returns wether base is a scanner type or fixed.

void scanner oServo s  )  [inherited]
 

Provide a servo for a scanner type sensor mount.

void status JAUS_STATE  istat  )  [inline]
 

Set status of component.

short value void   ) 
 

Provide emulated value. Distance from object in millimeterss.

Reimplemented from sensor_base.

void WSwrite void   ) 
 

Write object to shared memory.

int _DFC [inherited]
 

Distance from center of platform (MILLIMETERS).

oIR _ir [protected]
 

bool _locked [protected, inherited]
 

int _maximum_sensor_range [protected, inherited]
 

oServo* _servo [protected, inherited]
 

FIXED_RADIAN F_bearing [protected, inherited]
 

FIXED_RADIAN F_face [inherited]
 

where the IR is facing 0 is forward + is counterclock-wise.

FIXED_RADIAN F_orient [inherited]
 

Position (radians) around the robot from defined center position (0=forward).

To put it another way, this is where the sensor is mounted whereas face is which way IR beam is directed; no necessarily related.
