Example Program 18: MM_S18_Viz_GetUserData

Program Introduction

Description

When the robot obtains the picking path, the robot also obtains the custom output data from the Mech-Vision project.

File path

You can navigate to the installation directory of Mech-Vision and Mech-Viz and find the file by using the Communication Component/Robot_Interface/YASKAWA/sample/MM_S18_Viz_GetUserData path.

Project

Mech-Vision project (one or more custom ports need to be added to the Output Step) and Mech-Viz project (the tool is a depalletizing vacuum gripper)

Prerequisites

This example program is provided for reference only. Before using the program, please modify the program according to the actual scenario.

Program Description

This part describes the MM_S18_Viz_GetUserData example program.

Compared with the MM_S15_Viz_GetDoList example program, this example program contains only the following modification (the code of this modification is bolded). As such, only the modification is described in the following section. For information about the parts of MM_S18_Viz_GetUserData that are consistent with those of MM_S15_Viz_GetDoList, see Example Program 15: MM_S15_Viz_GetDoList.

Feature Code and description

Store custom data of waypoints

'received custom data is saved
'from R052
'R052 = offset_x;
'R053 = offset_y;
'R054 = offset_z;
SET R010 R052
SET R011 R053
SET R012 R054
In the Mech-Viz project, custom data refers to data output by the custom port(s) of the Output Step in Mech-Vision and then forwarded by Mech-Viz.

The robot runs the MM_GET_PLANDATA command to obtain the planned Vision Move data and custom data of waypoints, and then runs the MM_GET_PLANPOSE command to sequentially save the Vision Move data of waypoints to the variables R031 to R051 and the custom data of waypoints to the variables starting from R052.

The above code assigns the three pieces of custom data of the Vision Move waypoint (picking waypoint) in R052, R053, and R054 to R010, R011, and R012, respectively.

You can define the meaning of the custom data. For example, the three pieces of custom data could represent the robot’s offsets along the XYZ axes when moving to the picking waypoint.
