Taking the ABB industrial robot as an example, an industrial robot experimental platform with a hexagonal table structure was proposed. The experimental platform was built through functional design and process simulation, and a Unity3D virtual simulation experimental platform was constructed, including process virtual simulation and disassembly virtual simulation of industrial robots. The industrial communication standard OPC UA protocol was used to realize data communication between virtual and real industrial robots, and the synchronization of virtual and real robots movement was realized, the position error of virtual and real robots movement was analyzed. The experimental results show that the platform can provide virtual solutions for intelligent manufacturing and is also specific technology application under the concept of digital twins. It has strong promotion and applicability.
