Digital twins are one of the many revolutionary advancements in Industry 4.0 smart manufacturing and robotics. It allows manufacturers to accurately simulate, refine, and analyze their production workflows before implementing it on factory floors. Digital twins have built a fundamental attribute that has paved way for new technologies such as predictive maintenance, performance optimization, and data-driven decision-making.
Industrial computers are key enablers of digital twins by providing edge AI performance and on-premises reliability for real-time feedback. In this article, we’ll explore how digital twins are driving advancements in smart manufacturing and the essential role of industrial edge computers in making this technology a reality.
What is a Digital Twin?
A digital twin is an interactive and responsive virtual replica of a component or system that continuously synchronizes with its physical counterpart. IoT sensors and devices feed instantaneous telematics to accurately construct a digital mirror of the system. Engineers utilize digital twins across various Industry 4.0 deployment applications to interact and analyze workflows more efficiently.
Simulation vs Digital Twin
Although the process of a simulation and digital twin may seem to have overlapping purposes, there are distinct differences between the two. Digital twins are able to adapt and update with physical systems in real-time while simulations are fixed with predetermined inputs.
- Simulations: provide results under a set of predefined conditions and parameters. This is useful for analyzing behavioral results in testing scenarios.
- Digital Twins: symbiotic relationship that intakes real-time data for deeper analysis and optimized settings are relayed back to the physical asset. This is beneficial for on-going predictive maintenance and improving operational efficiencies.
