Smart Manufacturing with Artificial Intelligence and Digital Twin: A Brief Review

Digital twin and artificial intelligence technologies have proliferated as crucial enablers for Industry 4.0. With a digital twin, companies can digitally test and validate a product before it exists in the real world. By digitally recreating the planned production process for real-world use, engineers can identify any potential process changes before they happen. This brief review summarizes their general developments and the current state of AI integration in smart manufacturing and advanced robotics. This review also covers industrial automation and emerging techniques, such as 3D printing.
