Digital Twin of the Vertical Warehouse Application

Abstract

This thesis is commissioned by the HAMK Smart Research Unit at Häme University of Applied Sciences. The primary objective of this thesis has been to develop a digital twin of the Fisher Technik device known as Automated High-Bay Warehouse in TwinCAT 3 and Unreal Engine environment. Integrating software through Open Platform Communication Unified Architecture server, the project aims to establish a seamless connection between these platforms. Enabling integration and synchronization within the digital twin environment, this thesis project focuses on enhancing the capability and functionality of the simulation incorporating Unreal Engine features. In particular, the aim has been to produce a collision detection system with control of actuators and capable of receiving feedback from the sensors.

The theoretical background focuses on the significance of the digital twin in industrial automation and the machine safeguarding against potential damage or harm to its components. In addition, examination of the Open Platform Communication functionality and application covered the importance and creation of the communication system.

Unreal Engine 4.26 software, open62541 1.3 library and Visual Studio 2017 integrated development environments were used to develop a digital twin of the Automated High-Bay Warehouse. This solution provides a complete technique for client connection to the server, and server building with Open Platform Communication Unified Architecture framework. The project provides comprehensive documentation and explanation.

The project has resulted in a fully functional digital twin and provides simulation practises for the TwinCAT 3 programming. The thesis project has highlighted the need to understand the limits of the real-life machine and possibilities of the digital twin. It underscores the critical role of safety considerations in operating the device effectively.
