Key Technologies Driving Industry 4.0
1. Industrial Internet of Things (IIoT)
Connects machines, sensors, and devices for real-time monitoring.
Enables predictive maintenance to reduce downtime.
2. Big Data AI Analytics
Processes vast amounts of factory data to optimize production.
Uses machine learning for quality control and defect detection.
3. Cyber-Physical Systems (CPS)
Integrates physical machinery with digital controls.
Example: Smart robots adjusting operations in real-time.
4. Additive Manufacturing (3D Printing)
Enables on-demand, customized production.
Reduces waste compared to traditional subtractive manufacturing.
5. Digital Twins
Virtual replicas of physical assets for simulation and testing.
Helps in optimizing performance before real-world implementation.
6. Cloud Edge Computing
Cloud – Stores and processes massive datasets.
Edge – Enables real-time decision-making at the source (e.g., factory floor).
7. Autonomous Robots Cobots
Autonomous robots handle complex tasks (e.g., material handling).
Collaborative robots (cobots) work safely alongside humans.
8. Augmented Reality (AR) Virtual Reality (VR)
AR assists workers with real-time data overlays (e.g., maintenance guides).
VR trains employees in a simulated environment.
