1.2. Brief History of Robotics

Ancient Myths of mechanical men (e.g., Greek automata)

The concept of robots dates back to ancient civilizations where stories and myths depicted mechanical beings, often referred to as automata. These were imagined as self-operating machines or beings that could perform tasks automatically. For example, in Greek mythology, there were tales of mechanical men made of metal or clay that could help humans with labor.

Think of how in today’s world, movies and books often create stories about robots, like R2-D2 from Star Wars. Just like early myths inspired imaginations, these stories bring the idea of robots into our lives, showing how long humans have dreamed about creating machines that can act on their own.

1495 Leonardo da Vinci sketches a robotic knight

In 1495, the famous artist and inventor Leonardo da Vinci created sketches of a robotic knight. This design showed a machine that could sit, wave its arms, and even move its head. Though it wasn’t built during his lifetime, this early design represented a significant step in thinking about how to combine art and engineering into a machine that mimics human action.

Imagine if an artist today were to sketch a futuristic robot; Leonardo's sketches were a bit like that—combining creativity with engineering concepts. It shows that the concept of simulating human-like movements has fascinated people for centuries.

1950s Isaac Asimov formulates the 'Three Laws of Robotics'

In the 1950s, science fiction author Isaac Asimov introduced the 'Three Laws of Robotics' which are ethical guidelines for how robots should behave. These laws include: a robot may not injure a human being, a robot must obey orders from humans unless it conflicts with the first law, and a robot must protect its own existence unless it conflicts with the first or second law. These principles raised important questions about the safety and behavior of robots and set a framework for future discussions on robotics ethics.

Think of these laws like the rules in a video game. Just as players must follow rules to keep the game fair and safe, these laws remind us that robots should be designed to protect people and follow guidelines to behave appropriately.

1961 Unimate: First industrial robot at GM

In 1961, the Unimate became the first industrial robot used in a General Motors factory. It was designed to handle tasks like lifting heavy items in assembly lines, which significantly increased efficiency and safety in the workplace. This marked the beginning of the practical application of robotics in manufacturing, introducing machines that could operate autonomously in industrial environments.

Consider the way factories today use robots on assembly lines to assemble cars or electronics—just like how Unimate worked in its time, modern robots help workers by taking on dangerous and repetitive tasks, making production faster and safer.

2000s–Now Humanoids, autonomous vehicles, surgical robots

Since the 2000s, robotics has advanced dramatically with the development of humanoid robots, autonomous vehicles, and sophisticated surgical robots. These machines are built to perform complex tasks, often mimicking human capabilities or enhancing human abilities in fields such as healthcare and transportation. This era represents the seamless integration of robotics into various aspects of daily life and industry.

Think of self-driving cars that navigate city streets or surgical robots that assist doctors in performing delicate operations. These modern technologies are like the next level of robots—helping us by taking on tasks that are complex or risky, similar to how early robots began to support human work over half a century ago.
