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()ITEM_TYPE_ROBOT

After 5.4.0

You can use any of the following import methods:

fromrobodkimportrobolink,robomathRDK=robolink.Robolink()pose=robomath.eye()robolink.ITEM_TYPE_ROBOT
fromrobodk.robolinkimportRobolink,ITEM_TYPE_ROBOTfromrobodk.robomathimporteyeRDK=Robolink()pose=eye()ITEM_TYPE_ROBOT
fromrobodk.robolinkimport*fromrobodk.robomathimport*RDK=Robolink()pose=eye()ITEM_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

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.

2.6.robolinkutils.py

The robolinkutils sub-module provides utility functions using the Robolink module.

Warning

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

Get all the items of a specific type for which getLink() returns the specified item.

Parameters

  • item(Item) – The source Item

  • type_linked(int) – type of items to check for a link. None means any type.

Returns

A list of Items for which item.getLink return the specified item

Return type

list ofItem

robodk.robolinkutils. getAncestors ( item,parent_types=None )

Get the list of parents of an Item up to the Station, with type filtering (i.e. [ITEM_TYPE_FRAME, ITEM_TYPE_ROBOT, ..]). By default, it will return all parents of an Item with no regard to their type, ordered from the Item’s parent to the Station.

Parameters

  • item(Item) – The source Item

  • parent_types(list of ITEM_TYPE_*,optional) – The parent allowed types, such as ITEM_TYPE_FRAME, defaults to None

Returns

A list of parents, ordered from the Item’s parent to the Station.

Return type

list ofItem

robodk.robolinkutils. getLowestCommonAncestor ( item1,item2 )

Finds the lowest common ancestor (LCA) between two Items in the Station’s tree.

Parameters

  • item1(Item) – The first Item

  • item2(Item) – The second Item

Returns

The lowest common ancestor (LCA)

Return type

Item

robodk.robolinkutils. getAncestorPose ( item_child,item_parent )

Gets the pose between two Items that have a hierarchical relationship in the Station’s tree. There can be N Items between the two. This function will throw an error for synchronized axis.

Parameters

  • item_child(Item) – The child Item

  • item_parent(Item) – The parent Item

Returns

The pose from the child to the parent

Return type

robomath.Mat

robodk.robolinkutils. getPoseWrt ( item1,item2 )

Gets the pose of an Item (item1) with respect to an another Item (item2).

child.PoseWrt(child.Parent())# will return a forward pose from the parent to the childchild.Parent().PoseWrt(child)# will return an inverse pose from the child to the parenttool.PoseWrt(tool.Parent())# will return the PoseTool() of the tooltool.PoseWrt(station)# will return the absolute pose of the tool
Parameters

  • item1(robolink.Item) – The source Item

  • item2(robolink.Item) – The second Item

Returns

The pose from the source Item to the second Item

Return type

robomath.Mat

robodk.robolinkutils. setPoseAbsIK ( item,pose_abs )

Set the pose of the item with respect to the absolute reference frame, accounting for inverse kinematics. For instance, you can set the absolute pose of a ITEM_TYPE_TOOL directly without accounting for the robot kinematics. This function will throw an error for synchronized axis.

tool_item.setPoseAbs(eye(4))# will SET the tool center point with respect to the station at [0,0,0,0,0,0]setPoseAbsIK(tool_item,eye(4))# will MOVE the robot so that the tool center point with regard to the station is [0,0,0,0,0,0]
Parameters

  • item(robolink.Item) – The source Item

  • pose_abs(robomath.Mat) – pose of the item with respect to the station reference

robodk.robolinkutils. SolveIK_Conf ( robot,pose,toolpose=None,framepose=None,joint_config=[0,1,0] )

Calculates the inverse kinematics for the specified robot and pose. The function returns only the preferred solutions from the joint configuration as a 2D matrix. Returns a list of joints as a 2D matrix [N x M], where N is the number of degrees of freedom (robot joints) and M is the number of solutions. For some 6-axis robots, SolveIK returns 2 additional values that can be ignored.

Parameters

  • robot(robolink.Item) – The robot Item

  • pose(Mat) – pose of the robot flange with respect to the robot base frame

  • toolpose(Mat)——工具构成的机器人法兰(TCP)
