Getting Started Tutorial: Vision-Guided Robotic Picking of Metal Parts (Standard Interface Communication)
In this tutorial, you will learn how to deploy a simple 3D vision–guided robotic application of picking small metal parts in the Standard Interface communication mode.
Application Overview
-
Camera: Mech-Eye PRO M camera, mounted in eye to hand (ETH) mode
-
Calibration board: When the working distance is 1000 to 1500 mm, it is recommended to use the calibration board model CGB-035;when the working distance is 1500 to 2000mm, it is recommended to use the calibration board CGB-050
-
Robot: YASKAWA_GP8
-
Target object: track links (made of metal)
-
End tool: gripper
-
IPC:Mech-Mind IPC STD
-
Used software: Mech-Vision 1.8.2, Mech-Viz 1.8.2, Mech-Eye Viewer 2.3.1
-
Communication mode: Standard Interface communication

How to Deploy a Vision-Guided Robotic Application?
The deployment of the vision-guided robotic application can be divided into six phases, as shown in the figure below:
The following table describes the six phases of deploying a vision-guided robotic application.
| No. | Phase | Description |
|---|---|---|
1 |
Vision Solution Design |
Select the hardware model according to the project requirements, determine the mounting mode, vision processing method, etc. (This tutorial has a corresponding vision solution, and you do not need to design it yourself.) |
2 |
Vision system hardware setup |
Install and connect hardware of the Mech-Mind Vision System. |
3 |
Robot communication setup |
Load the robot Standard Interface program and the configuration files to the robot system and set up the Standard Interface communication between the vision system and the robot. |
4 |
Hand-eye calibration |
Perform the automatic hand-eye calibration in the eye-to-hand setup, to establish the transformation relationship between the camera reference frame and the robot reference frame. |
5 |
Workpiece locating |
Use the “General Workpiece Recognition” case project to calculate the workpiece poses and output the vision result. |
6 |
Pick and place |
Use Mech-Viz to create a workflow that can guide the robot to repeatedly pick and place workpieces. |
Next, follow subsequent sections to complete the application deployment.
