Collaborative Robots: Key Players in the Smart Factory Revolution

I. Introduction

Collaborative robots, commonly known as cobots, are a new breed of robots designed to work alongside humans in a shared workspace. Unlike traditional industrial robots that operate in isolation, cobots are built to assist human workers, enhancing productivity and safety in manufacturing environments.

The concept of the smart factory represents a significant leap in manufacturing, characterized by the integration of advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), and real-time data analytics. Smart factories utilize these technologies to create more efficient, flexible, and responsive production systems.

In this context, the importance of cobots cannot be overstated. They are pivotal in the transition towards smart manufacturing, providing capabilities that complement human skills and enabling businesses to adapt to rapid changes in demand and production processes.
