Creating a digital twin

Hello friends,

i need some help at creating a digital twin of a logistic system. The Box should go over the transport system. Then when it arrives at the end (detected by Sensor) the Plattform (white) in the middle should take it and put it in the shelf. It has a OPC UA connection and the various variables are available. I need some help appling this in unity bc i'm a beginner and not know all of the components.
