A Methodology for Developing Real-time Interface Protocol for Industrial Robots using LabVIEW

Abstract

Most robotic manufacturers use domain-specific programming languages (DSL), in contrast with general-purpose languages such as C++. By using DSL, it enables the optimization of solutions since the common attribute can be taken off from the language hence a more detailed and focus program can be created. However, these languages restrict the flexibility of creative programming. By using a broader and less restrictive programming language, a more innovative interface protocol can be created. This research paper will present a methodology of handshaking communication protocol with high flexibility and modular design of a LabVIEW based interface protocol. It will approach firstly to configure safety circuit by using Protective extra low-voltage (PELV) to provide mandatory safety, and secondly to configure Beckhoff EtherCAT and KUKA WorkVisual to translate signals and data to PLC for defined tasks. Electronic signals would mostly be controlled by in-house LabVIEW interface program and cDAQ. Machine accuracy before and after using the protocol was unaltered since the robot was controlled directly by its controller.
