Robotics in Manufacturing

The Evolution of Manufacturing: From Manual Labor to Robotics

Manufacturing began with manual labor, where human hands performed all tasks. This approach, while effective for small-scale production, had its limitations in terms of speed, consistency, and scalability. The advent of early mechanization during the Industrial Revolution marked a significant shift. Machines began to take over repetitive tasks, improving efficiency and laying the groundwork for modern manufacturing.

The introduction of industrial automation in the mid-20th century brought about the first robots in a factory. The first industrial robot, Unimate, was installed in a General Motors factory in 1961. These early robots, like Unimate, were designed to handle dangerous and repetitive tasks, such as die casting and spot welding, thereby increasing safety and productivity. Unimate operated with hydraulic actuators and followed commands from a magnetic drum, showcasing the potential of automation to revolutionize production. This era marked the beginning of a new phase where robots and manufacturing became inseparable.

Key Milestones in the Integration of Robotics in Manufacturing

The journey of manufacturing with robots is dotted with key milestones:

● 1961: Introduction of Unimate, the first industrial robot, in a General Motors assembly line. This event answers the question: when was the first robot used in manufacturing.
● 1980s: The rise of programmable robots, allowing for more complex and precise tasks, for example: assembling intricate electronic components and performing detailed welding.
