Robotics - from myth to machine

The concept of artificial mechanical beings predates the modern age by thousands of years. Ancient civilizations, notably the Greeks and Chinese, envisioned self-operating machines that mimicked human or animal behavior. Greek myths such as Hephaestus’ automated servants and Talos, the bronze giant who protected Crete, embody early imaginings of robots. In China, Han dynasty engineer Yan Shi reportedly presented a life-size, human-shaped automaton to King Mu of Zhou around 1000 BCE. The term robot itself was coined in 1920 by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots). Derived from the Czech word robota, meaning forced labor or drudgery, the term depicted humanoid workers created to serve humans—foreshadowing modern concerns and hopes about automation.

True mechanical automation began during the Renaissance with Leonardo da Vinci’s sketches of a mechanical knight. By the 18th century, intricate automata such as Jacques de Vaucanson’s Digesting Duck and mechanical music players captivated audiences, but these remained novelties rather than tools. The modern field of robotics emerged in the 20th century, born from the convergence of electrical engineering, computing, and mechanical design. The development of servo mechanisms, control systems, and eventually programmable computers laid the groundwork for today’s sophisticated robots.

The leap from mechanical curiosities to functional robots happened in the mid-20th century. In 1954, George Devol invented the first programmable robotic arm, which he later patented as "Unimate." Partnering with Joseph Engelberger, known as the "father of robotics," Unimate was first deployed in 1961 at a General Motors plant to perform repetitive and dangerous welding tasks. This was the dawn of the industrial robot era. Unimate's success led to a rapid expansion of robotic arms on automotive assembly lines, especially in Japan and the United States. Early robots were capable only of repetitive motion, with no adaptive intelligence, but they dramatically improved production speed, consistency, and worker safety.

Japan's FANUC, Kawasaki, and Yaskawa, along with Sweden’s ABB, became pioneers in the global industrial robotics market. Over the next few decades, robotic usage expanded beyond welding to painting, packaging, assembly, and inspection. The 1980s and 1990s saw the refinement of robotic systems with more sensors, feedback loops, and computer interfaces. By the 2000s, these systems integrated vision, machine learning, and real-time data processing—opening new horizons for industry and commerce. 

Robotics quickly found utility beyond terrestrial factories. NASA, recognizing the hazards of space, developed robotic systems to assist and sometimes replace astronauts in dangerous environments. In 1971, the Soviet Union’s Lunokhod 1 became the first successful robotic rover on the moon. In 1997, NASA’s Sojourner rover captivated the world as it explored Mars during the Pathfinder mission. This ushered in an era of robotic planetary exploration, with the more advanced rovers Spirit, Opportunity, Curiosity, and Perseverance following.

The Canadarm, first used on the Space Shuttle in 1981, and later versions on the International Space Station (ISS), revolutionized orbital operations, handling satellites and modules with precision impossible for human hands in space. Robonauts—humanlike robots developed by NASA—are being tested aboard the ISS for potential future missions to the Moon and Mars, paving the way for robots to serve as companions and helpers in long-duration spaceflight.

Robots have dramatically reshaped the global labor landscape. In manufacturing, especially in automotive and electronics industries, automation has replaced countless repetitive manual jobs. Advanced robotic systems can now inspect products for quality, assemble intricate components, and manage logistics at speeds unmatchable by humans. In agriculture, drones and robotic harvesters analyze crop health, sow seeds, and even pick fruit. In logistics and retail, Amazon’s Kiva robots automate warehouse fulfillment, reducing time and labor costs while increasing efficiency.

Even in service industries, robots are replacing or supplementing humans. Hospitality robots in Japan, robotic surgical assistants in hospitals, and chatbots in customer service all reflect this shift. While automation boosts productivity, it also brings job displacement, especially in low-skill sectors. As robots increasingly handle not just physical but also cognitive tasks (through AI), the workforce must pivot to roles emphasizing creativity, emotional intelligence, and complex problem-solving.

Robotics is advancing at an unprecedented rate, fueled by progress in artificial intelligence, machine learning, sensors, and battery technology. Modern robots are not only stronger and faster, but smarter. Sophisticated vision systems allow robots to interpret environments with near-human accuracy. With deep learning, robots can learn new tasks by observing humans, adapt to novel conditions, and even improve through trial and error.

Collaborative robots—or cobots—are designed to work alongside humans safely, making automation accessible even to small and medium enterprises. These flexible machines require minimal training and can be deployed in a variety of tasks, from laboratory work to packaging. Robots have entered homes in the form of vacuum cleaners (Roomba), personal assistants (social robots), and even companion pets. Bipedal and quadruped robots, such as Boston Dynamics’ Atlas and Spot, showcase astonishing agility, balance, and movement, hinting at real-world applications in search-and-rescue, military, and disaster zones.

The future of robotics is intertwined with the trajectory of artificial intelligence and connectivity. We are rapidly approaching an era where autonomous systems will operate transportation, deliver goods, maintain infrastructure, and provide care to the elderly and disabled.

Self-driving vehicles—essentially mobile robots—are already in testing or limited deployment around the world. Autonomous drones are being used for delivery, monitoring, and mapping. Healthcare robots may soon assist with surgery, rehabilitation, and elderly care on a mass scale.

Humanoid robots like Hanson Robotics' Sophia and Tesla’s proposed Optimus raise questions about the boundaries between machine and human, especially as natural language processing and facial expressions become more refined. In the long term, robots may become our partners in education, therapy, construction, and colonization of other planets. With the growth of synthetic biology and nano-robotics, even our internal biology may be augmented or repaired by tiny robotic systems.

Countries like Japan, South Korea, and Germany lead in industrial robot density, while the U.S. and China are rapidly innovating across sectors. The fusion of 5G networks, AI, and edge computing allows robots to make real-time decisions collaboratively. Open-source platforms and robotic kits are making robotics education more accessible to students and hobbyists worldwide.

Robotics, once a figment of ancient imagination, has become a transformative force reshaping every facet of human life—from factory floors to Martian plains. While the promise is vast—efficiency, safety, exploration, and innovation—the path forward must be walked with ethical foresight, societal planning, and global cooperation. The challenge is not whether robots will take over, but how we as a society choose to integrate them into our future. 

Will they liberate us from drudgery or deepen divides? The answer depends not on the robots themselves, but on the humans who create and control them.
