Digital twin system design for dual-manipulator cooperation unit

A measurement of designing virtual models based on physical entities is helpful for many companies to design their own virtual workshop models for workshop production scheduling and optimization, but a single virtual workshop model cannot reflect the interaction of physical and information objects required for intelligent manufacturing. However, the digital twin workshop is an effective approach to reflect the combination of virtual and physical then to optimize the operation of the workshop production. This study, focusing on the definition and role of digital twin engines in a digital twin workshop, researches on the concept of digital twin workshop, and takes the dual-manipulator cooperation production unit as an example to verify the proposed method for constructing the digital twin workshop.
