Overview

In ORiN2 SDK, DCOM (Distributed Component Object Model) of Microsoft Corporation is adopted as a distributed object technology. The DCOM based CAO can be used from various program languages such as C++, JAVA, and Visual Basic.

This article is meant to help to gather information on resources that can help you get started with interfacing with the CAO Engine in VB .NET (Visual Studio IDE). This article is not intended to aid you with programming in VB .NET nor how to use Visual Studio IDE.

Tools and Parts needed

The following sample code is provided “AS IS” under the MIT License. Programming support service of VB .NET is out of warranty. Please note that we do not provide any programming support service beyond basic setup and troubleshooting.

Previous Steps…

Please make sure that you have reviewed the ORiN 2 – Overview article and that your RC controller is properly setup. You can use the CAOTester to make sure that your PC is ready to communicate with the controller.

Setup your controller to accept messages from your PC.
Test communication using CAO Tester application
Configuring the Project to Point to the ORiN Library (CaoRCW)

Programming References

At this point you should be ready to begin programming your application to interface with your robot controller. When connecting to the controller you will need to specify the ORiN provider you are trying to use to establish communication. The provider differs based on the robot controller you are using. RC5, RC7, and RC7M controllers use the NetwoRC provider. RC8, RC8A, and COBOTTA controllers us the RC8 provider.

NetwoRC provider directory
C:\ORiN2\CAO\ProviderLib\DENSO\NetwoRC

RC8 Provider provider directory
C:\ORiN2\CAO\ProviderLib\DENSO\RC8

NOTE:
Please consult the Owner’s manual for information on how to program your DENSO Robot or details on specific robot commands.

Programming using the Provider

The following samples are for performing various basic but essential operations. The samples are for connecting using the RC8 Provider.

For more information you can reference Section 4 RC8 Programming Using the Provider from the RC8 Provider User’s Guide PDF document.

RC8 Provider User Guide Samples in VB .NET

This document intends to give you a better experience when trying to implement a command in the provider. We have “translated” the original VB6 samples in Section 5.0 from the RC8 provider guide into VB .NET language. Click here to download a copy.

Variable Sample

This sample code will read or write to the string global variable “S15” on the robot controller.

For more information reference Section 4.1 RC8 controller variable access.

Task Sample

This sample code will start or stop a robot program (Pro1.pcs), also known as tasks.

Prerequisites:

  • Controller must have a program named Pro1.pcs
  • Controller must be set to Auto mode

For more information reference Section 4.2 Task controller with RC8 controller.

Robot Motion Sample

This sample code will turn the motor ON or OFF. When the Start Robot button is pressed the robot will Move to position P10 and then to position P11.

Prerequisites:

  • Global variables P10 and P11 must have valid coordinate data
  • Robot state must be set to Auto mode

For more information reference Section 4.3 Robot control with RC8 controller.
