Adapter Generator Guide

You are viewing an old version of the documentation. You can switch to the documentation of the latest version by clicking the top-right corner of the page.

This guide introduces the Adapter generator and shows how to quickly generate an Adapter program using the Adapter generator. In the text below, “Adapter” is used as a short form for “Adapter program”.

Introduction

Adapter Generator is a tool for conveniently generating an Adapter program. Users may generate an Adapter program simply by configuring parameters on a graphical interface. Users may also customize the program files to implement more advanced features that go beyond the capabilities of the Standard Interface communication.

The Adapter program is a Python program that facilitates the communication between an external device (such as an industrial robot, host computer, or PLC) and Mech-Vision / Mech-Viz. It utilizes communication protocols supported by Python to establish the connection.

The relationship between the Adapter Generator and the Adapter program is shown in the image below.

adapter generator 0

The main function of the Adapter Generator is to configure the commands used for communication between the robot program and the Adapter program. The commands that trigger Mech-Vision / Mech-Viz to capture images and set Step parameters for Mech-Vision / Mech-Viz are listed in the configuring workflow of the Adapter Generator. Users may configure one or more of these commands according to the communication object and your practical requirements. The workflow of setting up the Adapter Generator is show in the image below.

adapter generator 3

The table below explains how to select the communication object for the Adapter program.

Communicate with

Description

Applicable scenarios

Mech-Vision

Obtain vision results or planned paths from Mech-Vision.

Simple path planning projects or projects that only involve sending vision results.

Mech-Viz

Mech-Viz plans the path by calling the vision service corresponding to a Mech-Vision project. Meanwhile, before the Mech-Viz project calls the vision service, Mech-Vision Step parameters do not need to be set or can be set in the parameter recipe.

More complicated path planning projects.

Mech-Vision & Mech-Viz

Mech-Viz plans the path and one of the following situations exists:

  • User needs to set Step parameters for Mech-Vision before the Mech-Viz project calls the vision service corresponding to a Mech-Vision project. Moreover, these Step parameters cannot be set in the parameter recipe.

  • When a Mech-Vision project that realizes special purposes is not called by the Mech-Viz project as a vision service, users may need to trigger such a project individually. For example, if the output of the “Procedure Out” Step of the Mech-Vision project is a dynamic value, this project needs to be triggered separately.

Users may consider to select this communication object when the two options above cannot meet project requirements.

Generate Adapter Program Using Adapter Generator

This section introduces how to rapidly generate an Adapter program using the Adapter Generator.

Before starting, please make sure that you have set up and opened a Mech-Vision solution and a Mech-Viz project (if any).

Open Adapter Generator

  • Do not close the solution when configuring the Adapter Generator; otherwise, the Adapter project will fail to be saved.

  • For convenience, users may hover the cursor over the “?” icon for details.

Configure “Basic settings”

  1. On the Basic settings tab page, configure Adapter project name, Communicate with, Communication protocol and Communication format.

    adapter generator 2
    The configuration workflow varies depending on the value of Communicate with. In other words, the left panel displays different configuration options based on the value of Communicate with. For example, when the value Mech-Vision is selected for “Communicate with”, you will only need to configure Basic settings, Mech-Vision input, Mech-Vision output and Status code settings.

    Configure Basic settings according to the instructions in the table below.

    Configuration entry Description

    Adapter project name

    This parameter specifies the Adapter project name. The project name is a string of letters, numbers or underscores and cannot start with a number.

    This parameter specifies the string terminator of commands. Common string terminators are \n, \r and \r\n. By default, the terminator is \r.

    Add start and end character

    This option specifies the start and end character of a command. After selecting this option, users should enter a start character and an end character. By default, both are space. For example, when the start and end character of the command “p,1\r” are respectively < and >, then the full form of the command is “<p,1>\r”.

  2. After finishing the configuration above, click Next. You will be directed to the command configuration interface based on the setting of “Communicate with”.

Configure “Mech-Vision input”

Set the command formats sent by the robot or host computer to Mech-Vision on the Mech-Vision input tab page. Configuration entries include Triggering command, Set Mech-Vision Step parameters and Get robot name from Mech-Vision.

Configure Triggering Command

  1. Configure the command that triggers Mech-Vision to capture images.

    This command is mainly used to trigger the Mech-Vision project to run. This command can also fulfill the following functions when corresponding parameters are configured.

    • If the Mech-Vision project has parameter recipes, this command can be used to switch the parameter recipe.

    • If the camera is mounted in the Eye In Hand method, or the Mech-Vision project has a “Path Planning” Step, this command can be used to input the robot capturing pose to the Mech-Vision project.
    adapter generator 4

    Configure Triggering command according to explanations in the table below.

    Name: The names of parameters in the command.

    Parameter value: The value of a parameter.

    Position: The position of a parameter in the command. The position order starts with 1. Two positions are separated by a comma.

    Length: The count of fields within a parameter value. (A field is the data between two adjacent string delimiters.

    Relationship between Position and Length: The position of a parameter equals the position of the previous parameter plus the length of the previous parameter.
    Name Parameter value Position Length

    Command code

    The code to trigger the Mech-Vision project to run. The default value is p. The value can be modified.

    1 (fixed value)

    1 (fixed value)

    Project ID

    The ID of the Mech-Vision project, a positive integer.

    2 (fixed value)

    1 (fixed value)

    Parameter recipe ID (optional)

    The ID of the parameter recipe in the Mech-Vision project, a positive integer.

    User-defined value

    1 (fixed value)

    Robot capturing pose (optional)

    If the camera mounting method is Eye In Hand, this command inputs the robot’s pose at the time of image capturing to the Mech-Vision project. The parameter value can be set to “JPs” or “JPs+Flange pose”.

    User-defined value

    • If you have selected “Euler angles” for the “Rotation format” parameter:

      • When the parameter value is “JPs”, the length is fixed to 6.

      • When the parameter value is “JPs+Flange pose”, the length is fixed to 12.

    • If you have selected “Quaternion” for the “Rotation format” parameter:

      • When the parameter value is “JPs”, the length is fixed to 6.

      • When the parameter value is “JPs+Flange pose”, the length is fixed to 13.

  2. If a value in the Parameter value, Position and Length columns is not gray, users may click it to modify the value as needed.

    • The command code should be unique among different commands.

    • Make sure that the fields occupied by different parameters do not overlap. For example, in the image below, the position and length of “robot capturing pose” are 3 and 12 respectively. If the position and length of “parameter recipe ID” are respectively 4 and 1, then the second field of “robot capturing pose” will overlap with the position of “parameter recipe ID”. If the position of “parameter recipe ID” is equal to or greater than 15, the “parameter recipe ID” and “robot capturing pose” will not overlap.

      adapter generator 24

    • There might be empty fields between parameter values. In preview, the empty field is described as the reserved position and filled in with 0s. For example, if the position and length of “parameter recipe ID” are respectively 3 and 1; and the position and length of “robot capturing pose” are respectively 6 and 12, position 4 and 5 are empty fields and will be filled in with 0s. If the position of “robot capturing pose” is changed to 4, there will be no empty field between this parameter value and that of “parameter recipe ID”. It is recommended to assign a proper value to “position” to avoid empty fields.

      adapter generator 25

  3. After completing the above configurations, click Preview to generate a command example.

    In the Command preview text box, users may hover the cursor over the field name to see the corresponding data, which will be highlighted.

status_code_dict = {ms.SUCCESS: 1, ms.INVALID_COMMAND: 2, ms.PROJECT_NOT_LOADED: 3,
                    ms.NO_POINT_CLOUD: 4, ms.NO_RESULT: 5, ms.PLAN_FAILED: 6,
                    ms.OTHER_ERROR: 7, ms.TIMEOUT: 8}

Add the code below to raise the TIMEOUT error.

raise AdapterError(ms.TIMEOUT)
