2.RoboDK API (robodk package)

Warning

The RoboDK API was refactored with version 5.4.0.

These changes are backward compatible, but not forward compatible. Effectively, the robolink.py module is now a sub-module of the robodk package (robodk.robolink), and robodk.py is now split into different sub-modules (robodk.robomath, robodk.robodialogs, robodk.robofileio).

You can access the documentation prior to version 5.4.0 here://www.sinclairbody.com/doc/en/PythonAPI/v0/index.html

Before 5.4.0

Most of our examples used the import method below:

fromrobolinkimport*fromrobodkimport*RDK=Robolink()pose=eye()我TEM_TYPE_ROBOT

After 5.4.0

You can use any of the following import methods:

fromrobodkimportrobolink,robomathRDK=robolink.Robolink()pose=robomath.eye()robolink.我TEM_TYPE_ROBOT
fromrobodk.robolinkimportRobolink,我TEM_TYPE_ROBOTfromrobodk.robomathimporteyeRDK=Robolink()pose=eye()我TEM_TYPE_ROBOT
fromrobodk.robolinkimport*fromrobodk.robomathimport*RDK=Robolink()pose=eye()我TEM_TYPE_ROBOT

The robodk package is the distributed entry point of the Python API. It is the common parent of all sub-packages and modules that constitute the Python API.

Overview of the RoboDK API:

2.2.robomath.py

The robomath module is a robotics toolbox for Python, based on Peter Corke’s Robotics Toolbox (regarding pose transformations):https://petercorke.com/toolboxes/robotics-toolbox/. The robomath sub-module includes the Mat class to represent transformations in 3D.

The following page provides a brief overview of the RoboDK API for Python://www.sinclairbody.com/offline-programming

An exception class for Matrix

class robodk.robomath. Mat ( rows=None,ncols=None )

Mat is a matrix object. The main purpose of this object is to represent a pose in the 3D space (position and orientation).

A pose is a 4x4 matrix that represents the position and orientation of one reference frame with respect to another one, in the 3D space.

Poses are commonly used in robotics to place objects, reference frames and targets with respect to each other.

2.5.roboapps.py

The roboapps sub-module is a RoboDK Apps toolbox. More info here:https://github.com/RoboDK/Plug-In-Interface/tree/master/PluginAppLoader

Warning

The roboapps sub-module is specific to the Python API.

class robodk.roboapps. RunApplication ( rdk=None )

Class to detect when the terminate signal is emitted to stop an action.

RUN=RunApplication()whileRUN.Run():# your main loop to run until the terminate signal is detected...
__init__ ( rdk=None )
RDK =None
time_last =-1
param_name =None
Run ( )

Run callback.

Returns

True as long as the App is permitted to run.

Return type

bool

robodk.roboapps. Unchecked ( )

Verify if the command “Unchecked” is present. In this case it means the action was just unchecked from RoboDK (applicable to checkable actions only).

Example for a ‘Checkable Action’:

defrunmain():ifroboapps.Unchecked():ActionUnchecked()else:roboapps.SkipKill()# Optional, prevents RoboDK from force-killing the action after 2 secondsActionChecked()

See also

Checked(),SkipKill(),KeepChecked()

robodk.roboapps. Checked ( )

Verify if the command “Checked” is present. In this case it means the action was just checked from RoboDK (applicable to checkable actions only).

Example for a ‘Checkable Action’:

defrunmain():ifroboapps.Unchecked():ActionUnchecked()else:roboapps.SkipKill()# Optional, prevents RoboDK from force-killing the action after 2 secondsActionChecked()

See also

Unchecked(),SkipKill(),KeepChecked()

robodk.roboapps. KeepChecked ( )

Keep an action checked even if the execution of the script completed (applicable to checkable actions only).

Example for a ‘Checkable Option’:

defrunmain():ifroboapps.Unchecked():ActionUnchecked()else:roboapps.KeepChecked()# Important, prevents RoboDK from unchecking the action after it has completedActionChecked()

See also

Unchecked(),SkipKill(),KeepChecked()

robodk.roboapps. SkipKill ( )

For Checkable actions, this setting will tell RoboDK App loader to not kill the process a few seconds after the terminate function is called. This is needed if we want the user input to save the file. For example: The Record action from the Record App.

Example for a ‘Momentary Action’:

defrunmain():ifroboapps.Unchecked():roboapps.Exit()# or sys.exit()else:roboapps.SkipKill()# Optional, prevents RoboDK from force-killing the action after 2 secondsActionChecked()
