Predefined unit conversion objects

Pointers to the unit converter objects used by this cSDH object.

The refered objects convert values between different unit systems. Example: convert angle values between degrees and radians, temperatures between degrees celsius and degrees fahrenheit or the like.

A cSDH object uses these converter objects to convert between external (user) and internal (SDH) units. The user can easily change the converter object that is used for a certain kind of unit. This way a cSDH object can easily report and accept parameters in the user or application specific unit system.

Additionally, users can easily add conversion objects for their own, even more user- or application-specific unit systems.

Detailed Description

#SDH::cSDH is the end user interface class to control a SDH (SCHUNK Dexterous Hand).

A general overview of the structure and architecture used is given here.

Remarks
  • The cSDH class provides methods to access the 7 axes of the SDH individually as well as on a finger level.
    • When accessing the axes individually then the following axis indices must be used to address an axis / some axes:
      • 0 : common base axis of finger 0 and 2
      • 1 : proximal axis of finger 0
      • 2 : distal axis of finger 0
      • 3 : proximal axis of finger 1
      • 4 : distal axis of finger 1
      • 5 : proximal axis of finger 2
      • 6 : distal axis of finger 2
    • When accessing the axes on finger level then every finger has 3 axes for a uniform interface of the access methods. Her the following finger axis indices must be used:
      • 0 : base axis of finger (for finger 1 this is a "virtual" axis with min angle = max angle = 0.0)
      • 1 : proximal axis of finger
      • 2 : distal axis of finger
  • Vector-like parmeters: The interface functions defined here make full use of the flexibility provided by the STL vector<T> type. I.E. for parameters of functions like axis indices or axis angles not only single numerical values can be given, but also vectors of int or double values. This way the same (overloaded) interface function can address a single axis individually or multiple axes in a call, as required by the application. Such parameters are herein refered to as "vectors".
  • Parameters for methods are checked for validity. In case an invalid parameter is given the method throws a cSDHErrorInvalidParameter exception.
  • The underlying physical unit system of parameters that do have a unit (like angles, velocities or temperatures) can be adapted to the users or the applications need. See also unit conversion objects". The default converter objects are set as the uc_* member variables (uc_angle, uc_angular_velocity, uc_angular_acceleration, uc_time, uc_temperature, uc_position). The units are changed in the communication between user application and cSDH object instance only (USERAPP and SDHLibrary-CPP in the overview figure"). For now the SDH firmware knows only about its internal unit system.

Constructor & Destructor Documentation

◆ cSDH()

cSDH::cSDH ( bool  _use_radians = false,
bool  _use_fahrenheit = false,
int  _debug_level = 0 
)

Constructor of cSDH class.

Creates an new object of type cSDH. One such object is needed for each SDH that you want to control. The constructor initializes internal data structures. A connection the SDH is not yet established, see OpenRS232() on how to do that.

After an object is created the user can adjust the unit systems used to set/report parameters to/from SDH. This is shown in the example code below. The default units used (if not overwritten by constructor parameters) are:

  • degrees [deg] for (axis) angles
  • degrees per second [deg/s] for (axis) angular velocities
  • seconds [s] for times
  • degrees celsius [deg C] for temperatures
Parameters
_use_radians: Flag, if true then use radians and radians/second to set/report (axis) angles and angular velocities instead of default degrees and degrees/s.
_use_fahrenheit: Flag, if true then use degrees fahrenheit to report temperatures instead of default degrees celsius.
_debug_level: The level of debug messages to print
  • 0: (default) no messages
  • 1: messages of this cSDH instance
  • 2: like 1 plus messages of the inner cSDHSerial instance
Examples:

Common use:

// Include the cSDH interface
#include <sdh.h>
// Create a cSDH object 'hand'.
cSDH hand();

The mentioned change of a unit system can be done like this:

// Assuming 'hand' is a cSDH object ...
// override default unit converter for (axis) angles:
hand.uc_angle = &cSDH::uc_angle_radians;
// override default unit converter for (axis) angular velocities:
// override default unit converter for (axis) angular accelerations:
// instead of the last 3 calls the following shortcut could be used:
hand.UseRadians();
// override default unit converter for times:
// override default unit converter for temperatures:
hand.uc_temperature = &cSDH::uc_temperature_fahrenheit;
// override default unit converter for positions:
hand.uc_position = &cSDH::uc_position_meter;

For convenience the most common settings can be specified as bool parameters for the constructor, like in:

// Include the cSDH interface
#include <sdh.h>
// Create a cSDH object 'hand' that uses

◆ ~cSDH()

cSDH::~cSDH ( )
virtual

Virtual destructor to make compiler happy

If the connection to the SDH hardware/firmware is still open then the connection is closed, which will stop the axis controllers (and thus prevent overheating).

◆ AdjustLimits()

void cSDH::AdjustLimits ( cSDHBase::eControllerType  controller)
private

Adjust the limits for the velocity and acceleration according to the controller type.

  • in pose controller the velocities and accelerations are always positive and thus the minimum is 0.0
  • in velocity based controllers the velocities and accelerations can be positive or negative and thus the minimum is -maximum

Definition at line 2111 of file sdh.cpp.

◆ CheckFirmwareRelease()

bool cSDH::CheckFirmwareRelease ( void  )

Check the actual release of the firmware of the connected SDH against the recommended firmware release.

Returns
true - if the actual firmware is the recommended one false - the actual firmware is NOT the recommended one (communication with the SDH might not work as expected)

This will throw a (cSDHErrorCommunication*) exception if the connection to the SDH is not yet opened.

Examples:
// Assuming 'hand' is a cSDH object ...
if ( hand.CheckFirmwareRelease() )
{
cout << "The firmware release of the connected SDH is the one recommended by this SDHLibrary\n";
}
else
{
cout << "The firmware release of the connected SDH is NOT the one recommended by this SDHLibrary\n";
cout << " Actual SDH firmware release " << hand.GetFirmwareRelease() << "\n";
cout << " Recommended SDH firmware release " << hand.GetFirmwareReleaseRecommended() << "\n";
}
See also
See GetFirmwareReleaseRecommended() to get the recommended SDH firmware release.

◆ Close()

void cSDH::Close ( bool  leave_enabled = false)

Close connection to SDH.

The default behaviour is to not leave the controllers of the SDH enabled (to prevent overheating). To keep the controllers enabled (e.g. to keep the finger axes actively in position) set leave_enabled to true. Only already enabled axes will be left enabled.

Parameters
leave_enabled- Flag: true to leave the controllers on, false (default) to disable the controllers (switch powerless)

This throws a (cSDHErrorCommunication*) exception if the connection was not opened before.

Examples:
// Assuming 'hand' is a cSDH object ...
// Close connection to SDH, power off controllers:
hand.Close();
// To leave the already enabled controllers enabled:
hand.Close( true );

Definition at line 888 of file sdh.cpp.

◆ EmergencyStop()

void cSDH::EmergencyStop ( void  )

Stop movement of all axes of the SDH and switch off the controllers

This command will always be executed sequentially: it will return only after the SDH has confirmed the emergency stop.

Bug:
For now this will NOT work while a GripHand() command is executing, even if that was initiated non-sequentially!
Examples:
// Assuming 'hand' is a cSDH object ...
// Perform an emergency stop:
hand.EmergencyStop();

Definition at line 1448 of file sdh.cpp.

◆ GetAxisReferenceVelocity() [2/2]

std::vector< double > cSDH::GetAxisReferenceVelocity ( std::vector< int >const &  axes)

Get the current reference velocity(s) of axis(axes). (This velocity is used internally by the SDH in eCT_VELOCITY_ACCELERATION mode).

Parameters
axes- A vector of axis indices to access.
  • The indices in axes are checked if they are valid axis indices.
  • If any axis index is invalid then a #SDH::cSDHErrorInvalidParameter* exception is thrown.
Returns
  • A vector of the reference velocities of the selected axes.
  • The values are converted to the selected external unit system using the configured uc_angular_velocity unit converter object.
  • The order of the elements of the axes vector and the returned values vector rv matches. I.e. rv[i] will be the value of axis axes[i] (not axis i).

See also GetAxisReferenceVelocity(int) for an overloaded variant to access a single axis.

Examples:
// Assuming "hand" is a cSDH object ...
// Switch to "velocity control with acceleration ramp" controller mode first.
// (When in another controller mode like the default eCT_POSE,
// then the reference velocities will not be valid):
hand.SetController( eCT_VELOCITY_ACCELERATION );
// Get reference axis velocity of all axes
std::vector<double> v = hand.GetAxisReferenceVelocity( hand.all_axes );
// now v is something like {0.1, 0.2, 0.3, 13.2, 0.5, 0.0, 0.7}
// Get reference axis velocity of axis 2 and 4
std::vector<int> axes24;
axes24.push_back( 2 );
axes24.push_back( 4 );
v = hand.GetAxisReferenceVelocity( axes24 );
// now v is something like {13.2, 0.0}
// Get reference axis velocity of axis 2
double v3 = hand.GetAxisReferenceVelocity( 2 );
// v3 is now something like 13.2
Remarks
  • the underlying rvel command of the SDH firmware is not available in firmwares prior to 0.0.2.6. For such hands calling rvel will fail miserably.
  • The availability of an appropriate SDH firmware is not checked here due to performance losses when this function is used often.

  • index 0 is sensor near motor of axis 0 (root)
  • index 1 is sensor near motor of axis 1 (proximal finger 1)
  • index 2 is sensor near motor of axis 2 (distal finger 1)
  • index 3 is sensor near motor of axis 3 (proximal finger 2)
  • index 4 is sensor near motor of axis 4 (distal finger 2)
  • index 5 is sensor near motor of axis 5 (proximal finger 3)
  • index 6 is sensor near motor of axis 6 (distal finger 3)
  • index 7 is FPGA temperature (controller chip)
  • index 8 is PCB temperature (Printed Circuit Board)
Remarks
  • The indices in sensors are checked if they are valid sensor indices.
  • If any sensor index is invalid then a #SDH::cSDHErrorInvalidParameter* exception is thrown.

To access a single temperature sensor use GetTemperature(int), see there.

Returns
The temperatures of the selected sensors are returned as std::vector<double> in the configured temperature unit system uc_temperature.
Examples:
// Assuming 'hand' is a cSDH object ...
// Get measured values of all sensors
std::vector<double> temps = hand.GetTemperature( hand.all_temperature_sensors );
// Now temps is something like { 38.500,37.250,35.750,37.250,33.500,36.500,32.250,59.625,52.500 }
// Get controller temperature only:
double temp_controller = hand.GetTemperature( 0 );
// Now temp_controller is something like 40.5
// If we - for some obscure islandish reason - would want
// temperatures reported in degrees fahrenheit, the unit
// converter can be changed:
hand.uc_temperature = &cSDH::uc_temperature_fahrenheit;
// Get all temperaturs again:
temps = hand.GetTemperature( hand.all_temperature_sensors );
// Now temps is something like {100.0, 96.8, 92.3, 97.7, 91.8, 96.8, 90.1, 137.5, 125.2}

◆ GetVelocityProfile()

cSDHBase::eVelocityProfile cSDH::GetVelocityProfile ( void  )

Get the type of velocity profile used in the SDH

Returns
the currently set velocity profile as integer, see eVelocityProfileType
Examples:
// Assuming 'hand' is a cSDH object ...
// Get the velocity profile from the SDH:
velocity_profile = hand.GetVelocityProfile();
// now velocity_profile is something like eVP_SIN_SQUARE or eVP_RAMP

Definition at line 993 of file sdh.cpp.

◆ GripHand()

double cSDH::GripHand ( eGraspId  grip,
double  close,
double  velocity,
bool  sequ = true 
)

Perform one of the internal eGraspId "grips" or "grasps"

Warning
THIS DOES NOT WORK WITH SDH FIRMWARE PRIOR TO 0.0.2.6 AND SDHLIBRARY-CPP PRIOR to 0.0.1.12 This was a feature in the ancient times of the SDH1 and now does work again for SDH firmware 0.0.2.6 and newer and SDHLIBRARY-CPP 0.0.1.12 and newer. We intend to further improve this feature (e.g. store user defined grips within the SDH) in the future, but a particular deadline a has not been determined yet.
Bug:
With SDH firmware > 0.0.2.6 and SDHLibrary < 0.0.1.12 GripHand() does not work (Bug 575)
=> Resolved in SDHLibrary 0.0.1.12
Bug:
With SDH firmware < 0.0.2.6 GripHand() does not work and might yield undefined behaviour there
=> Resolved in SDH firmware 0.0.2.6
Bug:
Currently the performing of a skill or grip with GripHand() can NOT be interrupted!!! Even if the command is sent with sequ=false it cannot be stoped or emergency stopped.
Parameters
grip- The index of the grip to perform 0..eGID_DIMENSION-1
close- close-ratio: [0.0 .. 1.0] where 0.0 is 'fully opened' and 1.0 is 'fully closed'
velocity- maximum allowed angular axis velocity in the chosen external unit system uc_angular_velocity
sequ- flag: if true (default) then the function executes sequentially and returns not until after the SDH has finished the movement. If false then the function returns immediately after the movement command has been sent to the SDH.
  • The close and velocity values are checked if they are in their allowed range.
  • If any value is invalid then no grip is perfomed, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.
Returns
The expected/elapsed execution time for the movement in the configured time unit system uc_time.
Remarks
  • Currently the actual movement velocity of an axis is determined by the SDH firmware to make the movements of all involved axes start and end synchronously at the same time. Therefore the axis that needs the longest time for its movement at its given maximum velocity determines the velocities of all the other axes.
  • The currently set target axis angles are not changed by this command
  • The movement uses the eMotorCurrentMode motor current modes "eMCM_GRIP" while gripping and then changes the motor current mode to "eMCM_HOLD". After the movement previously set motor currents set for mode "eMCM_MOVE" are overwritten!
Examples:
// Assuming 'hand' is a cSDH object ...
// Perform a fully opened centrical grip at 50 degrees per second:
hand.GripHand( hand.eGID_CENTRICAL, 0.0, 50.0, true );
// Now close it 50% with 30 degrees per second:
hand.GripHand( hand.eGID_CENTRICAL, 0.5, 30.0, true );
// Then close it completely with 20 degrees per second:
hand.GripHand( hand.eGID_CENTRICAL, 1.0, 20.0, true );

◆ IsOpen()

bool cSDH::IsOpen ( void  )
throw (
)
virtual

Return true if connection to SDH firmware/hardware is open.

Implements cSDHBase.

Definition at line 917 of file sdh.cpp.

◆ IsVirtualAxis()

bool cSDH::IsVirtualAxis ( int  iAxis)

Return true if index iAxis refers to a virtual axis.

Definition at line 126 of file sdh.cpp.

◆ MoveAxis() [1/2]

double cSDH::MoveAxis ( int  iAxis,
bool  sequ = true 
)

Like MoveAxis(std::vector<int>const&,bool), just for a single axis iAxis (or all axes if All is given).

Definition at line 1957 of file sdh.cpp.

◆ MoveAxis() [2/2]

double cSDH::MoveAxis ( std::vector< int >const &  axes,
bool  sequ = true 
)

Move selected axis/axes to the previously set target pose with the previously set velocity profile, (maximum) target velocities and target accelerations

Parameters
axes- A vector of axis indices to access.
sequ- flag: if true (default) then the function executes sequentially and returns not until after the SDH has finished the movement. If false then the function returns immediately after the movement command has been sent to the SDH (the currently set target axis angles for other axes will then be overwritten with their current actual axis angles).
  • The indices in axes are checked if they are valid axis indices.
  • If any index is invalid then no movement is performed, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.
Returns
The expected/elapsed execution time for the movement in the configured time unit system uc_time
Remarks
  • The axes will be enabled automatically.
  • Currently the actual movement velocity of an axis is determined by the SDH firmware to make the movements of all involved axes start and end synchronously at the same time. Therefore the axis that needs the longest time for its movement at its given maximum velocity determines the velocities of all the other axes.
  • Other axes than those selected by axes will NOT move, even if target axis angles for the axes have been set. (Remember: as axis 0 is used by finger 0 and 2 these two fingers cannot be moved completely idependent of each other.)
  • If sequ is true then the currently set target axis angles for other fingers will be restored upon return of the function.
  • If sequ is false then the currently set target axis angles for other fingers will be overwritten with their current actual axis angles

See also MoveAxis(int,bool) for an overloaded variant to move a single axis.

Examples:
// Assuming 'hand' is a cSDH object ...
// create an index vector for adressing axes 0, 4 and 2 (in that order)
std::vector<int> axes042;
axes042.push_back( 0 );
axes042.push_back( 4 );
axes042.push_back( 2 );
// Set a new target pose for axes 0, 4 and 2:
std::vector<double> angles042;
angles042.push_back( 0.0 );
angles042.push_back( -44.4 );
angles042.push_back( -22.2 );
hand.SetFingerTargetAngle( axes042, angles042 );
// First move Axis 0 only to its new target position:
hand.MoveAxis( 0 );
// The axis 0 has now reached its target position 0.0 degrees. The
// target poses for axes 4 and 2 are still set since the
// last MoveAxes() call was sequentially (und thus it could
// restore the previously set target axis angles of not
// selected axes after the movement finished)
// So move axes 4 and 2 now, this time non-sequentially:
std::vector<int> axes42;
axes42.push_back( 4 );
axes42.push_back( 2 );
double t = hand.MoveAxes( axis42, false );
// The two axes 4 and 2 are now moving to their target position.
// We have to wait until the non-sequential call has finished:
SleepSec( t );
// The axes 4 and 2 have now moved to -44.4 and -22.2.
// The target angles for other axes have by now been
// overwritten since the last MoveAxis() call was
// non-sequentially (und thus it could \b NOT restore the
// previously set target axis angles of not selected axes
// after the movement finished)
// Set new target angles for all axes ("home pose");
hand.SetAxisTargetAngle( hand.All, 0.0 );
// Now move all axes back to home pose:
hand.MoveAxes( hand.All );
Bug:
With SDH firmware < 0.0.2.7 calling MoveAxis() while some axes are moving in eCT_POSE controller type will make the joints jerk. This is resolved in SDH firmware 0.0.2.7 for the eCT_POSE controller type with velocity profile eVP_RAMP. For the eCT_POSE controller type with velocity profile eVP_SIN_SQUARE changing target points/ velocities while moving will still make the axes jerk.

◆ MoveFinger() [1/2]

double cSDH::MoveFinger ( int  iFinger,
bool  sequ = true 
)

Like MoveFinger(std::vector<int>const&,bool), just for a single finger iFinger (or all fingers if All is given).

Definition at line 2029 of file sdh.cpp.

◆ MoveFinger() [2/2]

double cSDH::MoveFinger ( std::vector< int >const &  fingers,
bool  sequ = true 
)

Move selected finger(s) to the previously set target pose with the previously set velocity profile, (maximum) target velocities and target accelerations.

Parameters
fingers- A vector of finger indices to access.
sequ- flag: if true (default) then the function executes sequentially and returns not until after the SDH has finished the movement. If false then the function returns immediately after the movement command has been sent to the SDH (the currently set target axis angles for other fingers will then be overwritten with their current actual axis angles).
  • The indices in fingers are checked if they are valid finger indices.
  • If any index is invalid then no movement is performed, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.
Returns
The expected/elapsed execution time for the movement in the configured time unit system uc_time
Remarks
  • The axes will be enabled automatically.
  • Currently the actual movement velocity of an axis is determined by the SDH firmware to make the movements of all involved axes start and end synchronously at the same time. Therefore the axis that needs the longest time for its movement at its given maximum velocity determines the velocities of all the other axes.
  • Other fingers than iFinger will NOT move, even if target axis angles for their axes have been set. (Exception: as axis 0 is used by finger 0 and 2 these two fingers cannot be moved completely idependent of each other.)
  • If sequ is true then the currently set target axis angles for other fingers will be restored upon return of the function.
  • If sequ is false then the currently set target axis angles for other fingers will be overwritten with their current actual axis angles

See also MoveFinger(int,bool) for an overloaded variant to move a single finger.

Examples:
// Assuming 'hand' is a cSDH object ...
// Set a new target pose for finger 0:
hand.SetFingerTargetAngle( 0, 0.0, 0.0, 0.0 );
// Set a new target pose for finger 1
hand.SetFingerTargetAngle( 1, 0.0, -10.0, -10.0 );
// Set a new target pose for finger 2
hand.SetFingerTargetAngle( 2, 20.0, -20.0, -20.0 );
// Move finger 0 only (and finger 2 partly as axis 0 also belongs to finger 2);
hand.MoveFinger( 0, true );
// The finger 0 has been moved to {20,0,0}
// (axis 0 is 'wrong' since the target angle for axis 0 has been overwritten
// while setting the target angles for finger 2);
// The target poses for finger 1 and 2 are still set since the
// last MoveFinger() call was sequentially.
// So move finger 1 now:
double t = hand.MoveFinger( 1, false );
// wait until the non-sequential call has finished:
SleepSec( t );
// The finger 1 has been moved to {0,-10,-10}.
// The target angles for finger 2 have been overwritten since the
// last MoveFinger() call was non-sequentially.
// Therefore this next call will just keep the fingers in their
// current positions:
hand.MoveFinger( hand.All, true );
// Set new target angles for all axes ("home pose");
hand.SetAxisTargetAngle( hand.All, 0.0 );
// Now move all axes back to home pose:
hand.MoveHand();
Bug:
With SDH firmware < 0.0.2.7 calling MoveFinger() while some axes are moving in eCT_POSE controller type will make the joints jerk. This is resolved in SDH firmware 0.0.2.7 for the eCT_POSE controller type with velocity profile eVP_RAMP. For the eCT_POSE controller type with velocity profile eVP_SIN_SQUARE changing target points/ velocities while moving will still make the axes jerk.

◆ SetAxisEnable() [4/4]

void cSDH::SetAxisEnable ( std::vector< int > const &  axes,
std::vector< double > const &  states 
)

Set enabled/disabled state of axis controller(s).

The controllers of the selected axes are enabled/disabled in the SDH. Disabled axes are not powered and thus might not remain in their current pose due to gravity, inertia or other external influences. But to prevent overheating the axis controllers should be switched of when not needed.

Parameters
axes- A vector of axis indices to access.
states- A vector of enabled states (0 = disabled, !=0 = enabled) to set. If any of the numbers in the vector is NaN (Not a Number) then the currently set enabled state will be kept for the corresponding axis.
Remarks
  • The lengths of the axes and states vector must match.
  • The indices can be given in any order, but the order of their elements must match, i.e. state[i] will be applied to axis axes[i] (not axis i).
  • The indices are checked if they are valid axis indices.
  • If any index is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.

See also SetAxisEnable(int,double), SetAxisEnable(int,bool) for overloaded variants to set a single axis enabled/disabled or to set the same state for all axes. See further SetAxisEnable(std::vector<int>const&,std::vector<bool>const&) for a variant that accepts a bool vector for the states to set.

Examples:
// Assuming 'hand' is a cSDH object ...
// Enable all axes:
hand.SetAxisEnable( hand.all_axes, hand.ones_v );
// Disable all axes:
hand.SetAxisEnable( All, 0 );
// Enable axis 0 and 2 while disabling axis 4:
std::vector<int> axes042;
axes042.push_back( 0 );
axes042.push_back( 4 );
axes042.push_back( 2 );
std::vector<double> states042;
states042.push_back( 1.0 );
states042.push_back( 0.0 );
states042.push_back( 1.0 );

motor_currents- A vector of motor currents to set. If any of the numbers in the vector is NaN (Not a Number) then the currently set axis motor current will be kept for the corresponding axis. The value(s) are expected in the configured motor current unit system uc_motor_current.
mode- the mode to set the maximum motor current for. One of the eMotorCurrentMode modes.
Remarks
  • The lengths of the axes and motor_currents vector must match.
  • The indices can be given in any order, but the order of their elements must match, i.e. motor_currents[i] will be applied to axis axes[i] (not axis i).
  • The indices are checked if they are valid axis indices.
  • The motor currents are checked if they are in the allowed range [0 .. f_max_motor_current_v], i.e. it is checked that motor_currents[i], converted to internal units, is in [0 .. f_max_motor_currents_v[axes[i]]].
  • If any index or value is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.

See also SetAxisMotorCurrent(int,double,eMotorCurrentMode) for an overloaded variant to set a single axis motor current or to set the same motor current for all axes.

Examples:
// Assuming "hand" is a cSDH object ...

◆ SetAxisTargetAcceleration() [1/2]

void cSDH::SetAxisTargetAcceleration ( int  iAxis,
double  acceleration 
)

Definition at line 1469 of file sdh.cpp.

◆ SetAxisTargetAcceleration() [2/2]

void cSDH::SetAxisTargetAcceleration ( std::vector< int >const &  axes,
std::vector< double >const &  accelerations 
)

Set the target acceleration(s) for axis(axes).

The target accelerations are stored in the SDH and are used only for:

  • the eCT_POSE controller type with eVP_RAMP velocity profile
  • the eCT_VELOCITY_ACCELERATION controller type

Setting the target acceleration will not affect an ongoing movement, nor will it start a new movement. To take effect an additional command must be sent:

Parameters
axes- A vector of axis indices to access.
accelerations- A vector of axis target accelerations to set. If any of the numbers in the vector is NaN (Not a Number) then the currently set axis target angle will be kept for the corresponding axis. The value(s) are expected in the configured angular acceleration unit system uc_angular_acceleration.
Remarks
  • The lengths of the axes and accelerations vector must match.
  • The indices can be given in any order, but the order of their elements must match, i.e. accelerations[i] will be applied to axis axes[i] (not axis i).
  • The indices are checked if they are valid axis indices.
  • The accelerations are checked if they are in the allowed range [0 .. f_max_velocity_v], i.e. it is checked that accelerations[i], converted to internal units, is in [0 .. f_max_velocity_v[axes[i]]].
  • If any index or value is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.

See also SetAxisTargetAcceleration(int,double) for an overloaded variant to set a single axis target acceleration or to set the same target acceleration for all axes.

Examples:
// Assuming "hand" is a cSDH object ...
// Set target axis acceleration of all axes to the given values:

◆ SetAxisTargetAngle() [2/2]

void cSDH::SetAxisTargetAngle ( std::vector< int > const &  axes,
std::vector< double > const &  angles 
)

Set the target angle(s) for axis(axes).

The target angles are stored in the SDH, the movement is not executed until an additional move command is sent.

Parameters
axes- A vector of axis indices to access.
angles- A vector of axis target angles to set. If any of the numbers in the vector is NaN (Not a Number) then the currently set axis target angle will be kept for the corresponding axis. The value(s) are expected in the configured angle unit system uc_angle.
Remarks
  • Setting the target angle will not make the axis/axes move.
  • The lengths of the axes and angles vector must match.
  • The indices can be given in any order, but the order of their elements must match, i.e. angles[i] will be applied to axis axes[i] (not axis i).
  • The indices are checked if they are valid axis indices.
  • The angles are checked if they are in the allowed range [f_min_angle_v .. f_max_angle_v], i.e. it is checked that angles[i], converted to internal units, is in [f_min_angle_v[axes[i]] .. f_max_angle_v[axes[i]]].
  • If any index or value is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.

◆ SetAxisTargetGetAxisActualAngle()

std::vector< double > cSDH::SetAxisTargetGetAxisActualAngle ( std::vector< int > const &  axes,
std::vector< double > const &  angles 
)

Set the target angle(s) and get the actual angle(s) for axis(axes).

Opposed to SetAxisTargetAngle() this will make the fingers move to the set target angles immediately, if the axis controllers are already enabled!

Parameters
axes- A vector of axis indices to access.
angles- A vector of axis target angles to set. If any of the numbers in the vector is NaN (Not a Number) then the currently set axis target angle will be kept for the corresponding axis. The value(s) are expected in the configured angle unit system uc_angle.
Returns
the actual angle(s) of the selected axes
Remarks
  • The lengths of the axes and angles vector must match.
  • The indices can be given in any order, but the order of their elements must match, i.e. angles[i] will be applied to axis axes[i] (not axis i).
  • The indices are checked if they are valid axis indices.
  • The angles are checked if they are in the allowed range [f_min_angle_v .. f_max_angle_v], i.e. it is checked that angles[i], converted to internal units, is in [f_min_angle_v[axis[i]] .. f_max_angle_v[axes[i]]].
  • If any index or value is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.

◆ SetAxisTargetGetAxisActualVelocity()

std::vector< double > cSDH::SetAxisTargetGetAxisActualVelocity ( std::vector< int > const &  axes,
std::vector< double > const &  velocities 
)

Set the target velocity(s) and get the actual velocitiy(s) for axis(axes).

The target velocities are stored in the SDH. The time at which a new target velocities will take effect depends on the current axis controller type:

  • in eCT_POSE controller type the new target velocities will not take effect until an additional move command is sent: MoveAxis(), MoveFinger(), MoveHand()
  • in eCT_VELOCITY and eCT_VELOCITY_ACCELERATION controller type the new target velocity will take effect immediately, if the axis controllers are already enabled. This means that in eCT_VELOCITY_ACCELERATION controller type the accelerations must be set with SetAxisTargetAcceleration() before calling SetAxisTargetVelocity().
Parameters
axes- A vector of axis indices to access.
velocities- A vector of axis target velocities to set. If any of the numbers in the vector is NaN (Not a Number) then the currently set axis target velocity will be kept for the corresponding axis. The value(s) are expected in the configured angular velocity unit system uc_angular_velocity.
Returns
the actual velocity(s) of the selected axes
Remarks
  • The lengths of the axes and velocities vector must match.
  • The indices can be given in any order, but the order of their elements must match, i.e. velocities[i] will be applied to axis axes[i] (not axis i).
  • The indices are checked if they are valid axis indices.
  • The velocities are checked if they are in the allowed range:
    • in eCT_POSE controller type: [0 .. f_max_velocity_v], i.e. it is checked that velocities[i], converted to internal units, is in [0 .. f_max_velocity_v[axes[i]]].
    • in eCT_VELOCITY and eCT_VELOCITY_ACCELERATION controller type: [-f_max_velocity_v .. f_max_velocity_v], i.e. it is checked that velocities[i], converted to internal units, is in [-f_max_velocity_v[axes[i]] .. f_max_velocity_v[axes[i]]].
  • If any index or value is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.

std::vector< double > const &  min_values,
std::vector< double > const &  max_values,
char const *  name 
)
protected

Generic set function: set some given axes to given values

Parameters
axes- a vector of axis indices
values- a vector of values
ll_set- a pointer to the low level set function to use
ll_get- a pointer to the low level get function to use (for those axes where the given value is NaN)
uc- a pointer to the unit converter object to use before sending values to ll_set
min_values- a vector with the minimum allowed values in internal units
max_values- a vector with the maximum allowed values in internal units
name- a string with the name of the values (for constructing error message)
Returns
the values returned from the SDH will be returned (for most commands ll_set/ll_get functions this will be the values, except for the cSDHSerial::tvav and cSDHSerial::tpap functions)
Remarks
  • The length of the axis and values vector must match.
  • The indices can be given in any order, but the order of the elements of axes and values must match too. I.e. values[i] will be applied to axis axes[i] (not axis i)
  • The indices are checked if they are valid axis indices.
  • The values are checked if they are in the allowed range [min_values .. f_max_values], i.e. it is checked that value[i], converted to the internal unit system by uc->ToInternal(), is in [min_values[axes[i]] .. max_values[axes[i]]].
  • If any index or value is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.
Bug:
Setting a single axis velocity only sets the velocities of all other axes to 0! So in order to address only some axes you must provide the desired velocity for all axes that you want to move in every call:
Bug:
With SDH firmware 0.0.2.16 and SDHLibrary-CPP 0.0.2.3 and binary communication (see also SDH_USE_BINARY_COMMUNICATION) setting of single (more precisely: less-than-all) axis parameters (position, velocity, acceleration) does not work as expected: If a single parameter is to be set for a single axis then that parameter is set to 0 for all other axes.
Workaround: If you want to access several different axes one after another then you have to keep a vector of the parameter for all your used axes in your application. You can then update single values of the vector on demand, but you have to send the complete vector to the SDHlibrary functions on every call.

◆ SetController()

void cSDH::SetController ( cSDHBase::eControllerType  controller)

Set the type of axis controller to be used in the SDH

With SDH firmware >= 0.0.2.7 this will automatically set valid default values for all target velocities, accelerations and positions in the SDH firmware, according to the controller type:

  • eCT_POSE:
    • target velocities will be set to default (40 deg/s)
    • target accelerations will be set to default (100 deg/(s*s))
    • target positions will be set to default (0.0 deg)
  • eCT_VELOCITY:
    • target velocities will be set to default (0 deg/s)
  • eCT_VELOCITY_ACCELERATION:
    • target velocities will be set to default (0 deg/s)
    • target accelerations will be set to default (100 deg/(s*s))

This will also adjust the lower limits of the allowed velocities here in the SDHLibrary, since the eCT_POSE controller allows only positive velocities while the eCT_VELOCITY and eCT_VELOCITY_ACCELERATION controllers require also negative velocities.

Attention
The availability of a controller type depends on the SDH firmware of the attached SDH and is checked here.
  • firmware <= 0.0.2.5: only eCT_POSE
  • firmware >= 0.0.2.6: eCT_POSE, eCT_VELOCITY, eCT_VELOCITY_ACCELERATION
Parameters
controller- identifier of controller to set. Valid values are defined in eControllerType
Examples:
// Assuming 'hand' is a cSDH object ...
// Set the pose controller in the SDH
// (see e.g. demo-simple.cpp, demo-simple2.cpp, demo-simple3.cpp for further examples)
hand.SetController( hand.eCT_POSE );
// Set the simple velocity controller in the SDH:
hand.SetController( hand.eCT_VELOCITY );
// Set the velocity with acceleration ramp controller in the SDH:
// (see e.g. demo-velocity-acceleration.cpp for further examples)
hand.SetController( hand.eCT_VELOCITY_ACCELERATION );

◆ SetFingerEnable() [4/4]

void cSDH::SetFingerEnable ( std::vector< int > const &  fingers,
std::vector< double > const &  states 
)

Set enabled/disabled state of axis controllers of finger(s).

The controllers of the axes of the selected fingers are enabled/disabled in the SDH. Disabled axes are not powered and thus might not remain in their current pose due to gravity, inertia or other external influences. But to prevent overheating the axis controllers should be switched of when not needed.

Parameters
fingers- A vector of finger indices to access.
states- A vector of enabled states (0 = disabled, !=0 = enabled) to set. If any of the numbers in the vector is NaN (Not a Number) then the currently set enabled state will be kept for the corresponding axis.
Remarks
  • The lengths of the fingers and states vector must match.
  • The indices can be given in any order, but the order of their elements must match, i.e. state[i] will be applied to finger fingers[i] (not finger i).
  • The indices are checked if they are valid finger indices.
  • If any index is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.
  • As axis 0 is used for finger 0 and 2, axis 0 is disabled only if both finger 0 and 1 are disabled.

See also SetFingerEnable(int,double), SetFingerEnable(int,bool) for overloaded variants to set a single finger enabled/disabled or to set the same state for all fingers. See further SetFingerEnable(std::vector<int>const&,std::vector<bool>const&) for a variant that accepts a bool vector for the states to set.

Examples:
// Assuming "hand" is a cSDH object ...
// Enable finger 1 and 2 while disabling finger 0 :
std::vector<double> states012;
states012.push_back( 0.0 );
states012.push_back( 1.0 );
states012.push_back( 1.0 );

◆ SetFingerTargetAngle() [1/2]

void cSDH::SetFingerTargetAngle ( int  iFinger,
double  a0,
double  a1,
double  a2 
)

Like SetFingerTargetAngle(int,std::vector<double>const&), just with individual finger axis angles a0, a1 and a2.

Definition at line 1764 of file sdh.cpp.

◆ SetFingerTargetAngle() [2/2]

void cSDH::SetFingerTargetAngle ( int  iFinger,
std::vector< double > const &  angles 
)

Set the target angle(s) for a single finger.

The target axis angles angle of finger iFinger are stored in the SDH. The movement is not executed until an additional move command is sent.

Parameters
iFinger- index of finger to access. This must be a single index.
angles- the angle(s) to set or None to set the current actual axis angles of the finger as target angle. This can be a single number or a vector of numbers. The value(s) are expected in the configured angle unit system uc_angle.
Remarks
  • Setting the target angles will not make the finger move.
  • The iFinger index is checked if it is a valid finger index.
  • The angles are checked if they are in the allowed range [0 .. f_max_angle_v], i.e. it is checked that angles[i], converted to internal units, is in [0 .. f_max_angle_v[finger_axis_index[iFinger][i]]].
  • If any index or value is invalid then none of the specified values is sent to the SDH, instead a #SDH::cSDHErrorInvalidParameter* exception is thrown.

See also SetFingerTargetAngle(int,double,double,double) for an overloaded variant to set finger axis target angles from single double values.

Examples:
// Assuming "hand" is a cSDH object ...
// Set target axis angles of finger 0 to { 10.0, -08.15, 47.11 } degrees
std::vector<double> angles;
angles.push_back( 10.0 );
angles.push_back( -08.15 );
angles.push_back( 47.11 );
hand.SetFingerTargetAngle( 0, angles );
// Set target axis angles of finger 1 to { 0.0, 24.7, 17.4 } degrees
angles[0] = 0.0; // "virtual" base axis of finger 1
angles[1] = 24.7;
angles[2] = 17.4;
hand.SetFingerTargetAngle( 1, { 0.0, 24.7, 17.4 } );
// Set target axis angles of all axes of finger 0 to 12.34 degrees
hand.SetFingerTargetAngle( 0, 12.34, 12.34, 12.34 );
// REMARK: the last command changed the previously set target axis
// angle for axis 0, since axis 0 is used as base axis for both
// finger 0 and 2!

Definition at line 1755 of file sdh.cpp.

◆ SetVelocityProfile()

void cSDH::SetVelocityProfile ( eVelocityProfile  velocity_profile)

Set the type of velocity profile to be used in the SDH

Parameters
velocity_profile- Name or number of velocity profile to set. Valid values are defined in eVelocityProfileType
Examples:
// Assuming 'hand' is a cSDH object ...
// Set the sin square velocity profile in the SDH:
hand.SetVelocityProfile( hand.eVP_SIN_SQUARE );
// Or else set the ramp velocity profile in the SDH:
hand.SetVelocityProfile( hand.eVP_RAMP )

Definition at line 986 of file sdh.cpp.

◆ Stop()

void cSDH::Stop ( void  )

Stop movement of all axes but keep controllers on

This command will always be executed sequentially: it will return only after the SDH has confirmed the stop

Bug:
For now this will NOT work while a GripHand() command is executing, even if that was initiated non-sequentially!
Bug:
With SDH firmware < 0.0.2.7 this made the axis jerk in eCT_POSE controller type. This is resolved in SDH firmware 0.0.2.7 for the eCT_POSE controller type with velocity profile eVP_RAMP. For the eCT_POSE controller type with velocity profile eVP_SIN_SQUARE changing target points/ velocities while moving will still make the axes jerk.
=> Partly resolved in SDH firmware 0.0.2.7
Examples:
// Assuming 'hand' is a cSDH object ...
// Perform a stop:
hand.Stop();

Definition at line 939 of file sdh.cpp.

◆ ToIndexVector()

std::vector< int > cSDH::ToIndexVector ( int  index,
std::vector< int > &  all_replacement,
int  maxindex,
char const *  name 
)
protected

Internal helper function: return a vector of checked indices according to index.

Parameters
index- The index to vectorize or All
all_replacement- a vector to return if index is All
maxindex- the index is checked if in [0..\ maxindex[ (i.e. not including maxindex)
name- A name for the things index, used to report out of bounds errors
Returns
  • If index is All then all_replacement is returned.
  • If index is a single number >= 0 then it is checked if in [0..\ maxindex[ and a vector of length 1 is returned containing only index.
  • In case index exceeds maxindex a (cSDHErrorInvalidParameter*) exception is thrown.

Definition at line 492 of file sdh.cpp.

◆ UpdateSettingsFromSDH()

void cSDH::UpdateSettingsFromSDH ( )
private

Update settings like min/max velocities and accelerations from the connected SDH

Bug:
For SDHLibrary prior to 0.0.2.9 the settings read from the SDH were not used correctly when a non default unit system (degrees) was used
=> Resolved in SDHLibrary 0.0.2.9

Definition at line 2067 of file sdh.cpp.

◆ UseDegrees()

void cSDH::UseDegrees ( void  )

Shortcut to set the unit system to degrees.

After calling this (axis) angles are set/reported in degrees and angular velocities are set/reported in degrees/second

Examples:
// Assuming 'hand' is a cSDH object ...
// make hand object use degrees and degrees/second for angles and angular velocities
hand.UseDegrees();
// as degrees, degrees/second are the default this is needed only if the
// unit system was changed before

Definition at line 594 of file sdh.cpp.

◆ UseRadians()

void cSDH::UseRadians ( void  )

Shortcut to set the unit system to radians.

After calling this axis angles are set/reported in radians and angular velocities are set/reported in radians/second

Examples:
// Assuming 'hand' is a cSDH object ...
// make hand object use radians and radians/second for angles and angular velocities
hand.UseRadians();

Definition at line 580 of file sdh.cpp.

◆ WaitAxis() [1/2]

void cSDH::WaitAxis ( int  iAxis,
double  timeout = -1.0 
)

Like WaitAxis(std::vector<int>const&,double), just for a single axis iAxis, see there for details and examples.

If iAxis is All then wait for all axes axes.

Definition at line 1192 of file sdh.cpp.

◆ WaitAxis() [2/2]

void cSDH::WaitAxis ( std::vector< int > const &  axes,
double  timeout = -1.0 
)

Wait until the movement(s) of of axis(axes) has finished

The state of the given axis(axes) is(are) queried until all axes are no longer moving.

Parameters
axes- A vector of axis indices to access.
timeout- a timeout in seconds or -1.0 (default) to wait indefinetly.
  • The indices in axes are checked if they are valid axis indices.
  • If any axis index is invalid then a #SDH::cSDHErrorInvalidParameter* exception is thrown.
    • If timeout < 0 then this function will wait arbitrarily long
    • If a timeout is given then this function will throw a cSDHErrorCommunication exception if the given axes are still moving after timeout many seconds

See also WaitAxis(int,double) for an overloaded variant to wait for a single axis or all axes.

Bug:
Due to a bug in SDH firmwares prior to 0.0.2.6 the WaitAxis() command was somewhat unreliable there. When called immediately after a movement command like MoveHand(), then the WaitAxis() command returned immediately without waiting for the end of the movement. With SDH firmwares 0.0.2.6 and newer this is no longer problematic and WaitAxis() works as expected.
=> Resolved in SDH firmware 0.0.2.6
Bug:
With SDH firmware 0.0.2.6 WaitAxis() did not work if one of the new velocity based controllers (eCT_VELOCITY, eCT_VELOCITY_ACCELERATION) was used. With SDH firmwares 0.0.2.7 and newer this now works. Here the WaitAxis() waits until the selected axes come to velocity 0.0
=> Resolved in SDH firmware 0.0.2.7
Examples:
Example 1, WaitAxis and eCT_POSE controller, see also the demo program demo-simple3:
// Assuming "hand" is a cSDH object ...
hand.SetController( eCT_POSE );
// Set a new target pose for axis 1,2 and 3
std::vector<int> axes123;
axes123.push_back( 1 );
axes123.push_back( 2 );
axes123.push_back( 3 );
std::vector<double> angles123;
angles123.push_back( -20.0 );
angles123.push_back( -30.0 );
angles123.push_back( -40.0 );
hand.SetAxisTargetAngle( axes123, angles123 );
// Move axes there non sequentially:
hand.MoveAxis( axes123, false );
// The last call returned immediately so we now have time to
// do something else while the hand is moving:
// ... insert any calculation here ...
// Before doing something else with the hand make sure the
// selected axes have finished the last movement:
hand.WaitAxis( axes123 );
// go back home (all angles to 0.0):
hand.SetAxisTargetAngle( hand.All, 0.0 );
// Move all axes there non sequentially:
hand.MoveAxis( hand.All, False );
// ... insert any other calculation here ...
// Wait until all axes are there, with a timeout of 10s:
hand.WaitAxis( hand.All, 10.0 );
// now we are at the desired position.

Example 2, WaitAxis and eCT_VELOCITY_ACCELERATION controller, see also the demo program demo-velocity-acceleration

// Assuming "hand" is a cSDH object ...
hand.SetController( eCT_VELOCITY_ACCELERATION);
// Set a new target velocity for axis 1,2 and 3
std::vector<int> axes123;
axes123.push_back( 1 );
axes123.push_back( 2 );
axes123.push_back( 3 );
std::vector<double> velocities123;
velocities123.push_back( -20.0 );
velocities123.push_back( -30.0 );
velocities123.push_back( -40.0 );
hand.SetAxisTargetVelocity( axes123, velocities123 ); // this will make the axes move!
// The last call returned immediately so we now have time to
// do something else while the hand is moving:
// ... insert any calculation here ...
// to break and stop the movement just set the target velocities to 0.0
velocities123[0] = 0.0;
velocities123[1] = 0.0;
velocities123[2] = 0.0;
hand.SetAxisTargetVelocity( axes123, velocities123 ); // this will make the axes break with the default (de)acceleration
// The previous command returned immediately, so
// before doing something else with the hand make sure the
// selected axes have stopped:
hand.WaitAxis( axes123 );
// now the axes have stopped
