  2. Variable-type parameters should use local variables, which take effect only in the program.

  3. Parameters can be defined as IN parameters or OUT parameters.

The KUKA Standard Interface provides the following subprograms.

Initialize Communication

This subprogram sets the name of the XML file used for setting up the TCP/IP communication, flag for successful communication, flag for successful data reception, and wait time before the program stops trying to establish the communication.

Subprogram

MM_Init_Socket(XML_Name[]:IN,Alive_Flag:IN,Recv_Flag:IN,Time_Out:IN)

Parameters

Name Description

IN parameters

XML_Name[]

Name of the XML file, case-sensitive.

Alive_Flag

ALIVE flag number in the XML file. When the flag is set to ON, the communication is successfully established.

Recv_Flag

RECEIVE flag number in the XML file. When the flag is set to ON, the robot has successfully received data.

Time_Out

Wait time in seconds before stopping connection attempt.

Example

MM_Init_Socket(“XML_Kuka_MMIND”,873,871,60)

This example sets the XML file for setting up communication as XML_Kuka_MMMIND, the flag for successful communication as 873, the flag for successful data reception as 871, and wait time as 60 seconds.

Start Mech-Vision Project

This subprogram is for applications that use Mech-Vision. It runs the corresponding project to acquire and process data. It applies for applications that use Mech-Vision but not Mech-Viz.

Subprogram

MM_Start_Vis(Job:IN,Pos_Num_Need:IN,SendPos_Type:IN,MM_J:IN)

Parameters

Name Description

IN parameters

Job

Mech-Vision project ID, which can be viewed before the project name in the Project List panel in Mech-Vision.

Pos_Num_Need

The expected number of vision points for Mech-Vision to send. The vision point contains the vision pose, corresponding point cloud, label, scaling, etc. Value range: 0–20, in which 0 indicates that all vision points will be received.

SendPos_Type

The type of the robot pose to be sent to Mech-Vision. Value range: 0 to 3.

  • 0: No robot poses need to be sent to the vision system. If the camera is mounted in the Eye To Hand mode, the image capturing process is independent of the robot pose, and therefore the robot pose is not needed.

  • 1: The robot pose in the current joint positions together with the current flange pose will be sent to the vision system. It is recommended to set this value when the camera is mounted in the Eye In Hand mode. When this parameter is set to this value, the “Path Planning” Step in the Mech-Vision project will use the joint positions sent by the robot. If the flange pose data are all 0, the vision system ignores the flange pose data.

  • 2: The robot pose in the current flange pose will be sent to the vision system. It is recommended to set this value when the camera is mounted in the Eye In Hand mode or in other scenarios where only the flange pose data is available (such as truss robots).

  • 3: The robot pose in the joint positions defined by the user will be sent to the vision system. It is recommended to set this value when the camera is mounted in the Eye To Hand mode. When the Mech-Vision project contains the “Path Planning” Step, the joint positions sent by the robot will be used as the start pose.

MM_J

E6AXIS variable for storing the joint positions of the start point when SendPose_Type = 3.

Example

MM_Start_Vis(1,1,1,MM_J)

This example triggers Mech-Vision project No.1 to run, and asks the Mech-Vision project to send over one vision point. The robot sends its current joint positions and flange pose when this subprogram is called as the image-capturing pose.

Example

In the line below, “1” is the Config ID, and “3” is the Step ID. “xOffset”, “yOffset” and “zOffset” are parameter key names; and “10”, “20” and “30” are their respective values. Add this line to the property_config file.

write, 1, 3, xOffset, 10
write, 1, 3, yOffset, 20
write, 1, 3, zOffset, 30

When the robot calls the subprogram below, Mech-Viz sets the values of the parameters whose key names are “xOffset”, “yOffset” and “zOffset” respectively to “10”, “20” and “30”.

mm_set_property(1,MM_Status)

This example sets the values of the parameters whose key names are “xOffset”, “yOffset” and “zOffset” respectively to “10”, “20” and “30”, and stores the received status code in the “MM_Status” variable.
