Evolution of robotics in manufacturing

Industrial robots have been helping humans carry out the three Ds of robotics – “dull, dangerous, and dirty work” – for well over 50 years. Today, advances in smart technology are making manufacturing robots more connected and capable of collaborating with humans to tackle more complex processes.

Physical robots such as robotic arms, cobots, and mobile robotic systems are a central part of modern manufacturing. They often operate within broader automation systems that combine software, controls, and connected machines to coordinate work with reduced human intervention. Together with technologies like AI and advanced analytics, these systems help manufacturers respond faster to changing demand while maintaining high standards for quality, efficiency, and cost.

Robotics in manufacturing refers to the use of programmable machines to perform physical tasks. These tasks are often repetitive, dangerous, or require high precision – such as welding, pick-and-place operations, or assembling complex components. Manufacturing robots come in many forms, including articulated robotic arms, collaborative robots (cobots), and mobile robots, but they all share a common purpose: carrying out physical work with consistent speed and accuracy.

Automation in manufacturing is a broader concept. It describes the overall system that coordinates production activities with minimal human intervention. Automation combines software, control systems, data platforms, and connected equipment – including robots – to manage and optimize manufacturing operations. Increasingly powered by artificial intelligence, modern automation environments use cloud-based platforms, real-time data, and advanced analytics to monitor performance, streamline workflows, and quickly adapt to changing production demands.

In simple terms, robotics is a key component of manufacturing automation. Robots handle the physical tasks on the factory floor, while automation systems connect those machines to production planning, enterprise software, and operational data. Together, they enable manufacturing processes to run more efficiently, respond faster to change, and operate as an integrated system from the shop floor to the business level.

Early manufacturing automation consisted of basic mechanical systems and conveyer belts that moved materials faster. In 1961, GM installed one of the first manufacturing robots, Unimate, to handle die casting and welding. This marked the beginning of modern manufacturing robotics driven largely by the auto industry. These robots excelled at activities that required speed, strength, and precision. The result was increased output, better product quality, and lower costs.

By the early 90s, better sensors and control systems made robots more flexible. Instead of performing one fixed task, robots could support broader manufacturing activities, such as material handling, injection molding, packaging, and palletizing. In the 2000s, robots became more connected to computerized manufacturing systems. This allowed different machines and robotic tools to work together as part of a coordinated production line. As Industry 4.0 gained momentum, technologies like the Industrial Internet of Things (IIoT), cloud platforms, and data analytics helped manufacturers connect equipment and operational data to improve performance.

More recently, integration with ERP and MES platforms has made robotics even more powerful. Modern manufacturing robots can coordinate processes in real time, support automated decisions, and respond to real conditions on the shop floor to improve efficiency across the plant.

While traditional industrial robots were often programmed to perform the same repetitive tasks, today’s robotics systems operate within much more connected environments. In smart factories, robots, equipment, and business systems are linked through IoT sensors and integrated cloud platforms, allowing data to flow between them. Combined with AI and advanced analytics, this connectivity allows robots and production systems to adapt to changing conditions on the fly – such as scaling up production to meet spikes in demand or shifting product lines when materials are scarce.

In some advanced facilities, robotics and automation systems operate with very little human intervention. These “dark factories” can run around the clock without lighting or on-site staff for extended periods. For example, Japanese-based Fanuc manufactures robotics in facilities that operate 24 hours a day for up to 30 days without human assistance. The lights-out Changping Smart Factory in Beijing can produce a smartphone every three seconds with the help of AI technology. While it’s unlikely all manufacturing operations will be fully automated, it’s clear that smart, connected robotics will play an increasingly important role in modern factories.
