Ancient History and Mythical Origins:
The story of humanoid robots starts not in labs or factories, but in the distant corners of human imagination. Around the 4th century BCE, Greek mythology introduced the idea of mechanical beings designed in human shape. **Hephaestus **had golden handmaidens that helped him in his forge, and Talos was a bronze automaton that protected Crete by throwing boulders at invaders. These stories showed humanity’s early interest in making life-like machines to serve and protect.
Meanwhile, in the 3rd century BCE in China, a Taoist text talked about an inventive engineer named Yan Shi. He presented a realistic mechanical figure to King Mu of Zhou. This automaton could walk, sing, and even flirt but was taken apart when it became too convincing. These mythological stories sparked the belief that humans could someday create companions that resemble us in form and function.
"Automaton: A self-operating machine or mechanism, often resembling a human or animal, that performs tasks automatically"
The Renaissance era bridged the gap, turning distant fantasies into tangible designs. In 1495, the visionary Leonardo da Vinci sketched what is considered one of the first verifiable blueprints for a humanoid automaton: a mechanical knight wearing armor, operated by a complex system of pulleys, cables, and gears.
This device was designed to sit up, move its arms, and turn its head, showing da Vinci’s mix of anatomy and engineering. Although it was never built during his lifetime, it marked an important shift from myth to mechanics. It inspired future inventors to create automated, human-like figures.
The Birth of the Modern Concept (Early 20th Century):
The beginning of the 20th century turned these ideas into cultural and scientific discussions. In 1921, Czech writer Karel Čapek introduced the term “robot” in his play R.U.R. (Rossum’s Universal Robots). The term comes from the Czech word “robota,” which means forced labor.
The play showed artificial workers rising against their creators. It sparked global conversations about the ethics and risks of synthetic beings. Building on this, in 1942, science fiction author Isaac Asimov came up with the “Three Laws of Robotics” in his short story “Runaround.” These laws stated that robots must protect humans, obey orders, and keep themselves safe. These principles would shape robotics ethics in the real world for many years.
Post-War Foundations and Early Autonomy (1940s–1960s):
After World War II, advancements moved the field from fiction to prototypes. In 1949, British scientist William Grey Walter created simple, tortoise-shaped robots. They had sensors that allowed them to navigate their environments on their own and avoid obstacles with basic feedback loops. This showed that self-directed machines were possible.
Then, in the 1960s, practical industrial automation began to develop. George Devol patented the first programmable robotic arm in 1954. Joseph Engelberger commercialized it as Unimate, which was installed in a **General Motors **factory in 1961 to handle hot die-cast metal parts. Although not humanoid, Unimate laid the foundation for robotic manipulation, proving that machines could perform repetitive and dangerous tasks reliably.
The Dawn of True Humanoid Robots (1970s–1980s):
The 1970s marked the emergence of real humanoid robots. In 1972, researchers at Waseda University in Japan introduced WABOT-1, the world’s first full-scale anthropomorphic robot. It had limbs and a head, enabling it to walk on two legs, grasp objects, and hold simple conversations using voice recognition and synthesis. This breakthrough demonstrated that it was possible to combine movement, handling objects, and interaction. Building on this success, Waseda launched WABOT-2 in 1984. This enhanced version could read sheet music and play a keyboard organ, blending robotics with art and showcasing improvements in vision and dexterity.
Mobility and Human-Like Movement (1990s–2000s):
The 1990s and early 2000s experienced fast growth in mobility and human interaction. In 2000, Honda launched ASIMO, a compact humanoid robot that could walk, climb stairs, recognize faces and gestures, and even run at speeds of up to 3.7 miles per hour. ASIMO became a global symbol by appearing in everyday situations, like serving drinks or conducting orchestras. Soon after, in 2003, Sony introduced QRIO, a smaller and more agile humanoid. QRIO could dance, run, and recover from falls, demonstrating its balance and flexibility.
Improvements And Real-World Applications:
As the decade went on, companies like Boston Dynamics made significant improvements in their physical capabilities. Their Atlas **robot, which developed throughout the 2010s, could perform acrobatic moves like backflips and parkour, thanks to better hydraulics and AI. In 2021, Tesla joined the effort by announcing **Optimus, a general-purpose humanoid designed for household tasks. This indicated a shift toward consumer applications.
Commercialization and Mass Deployment:
This progress, from basic autonomy in the mid-20th century to more complex AI integration, has been fueled by lower hardware costs, increased computing power, and improvements in machine learning. By the 2020s, humanoid robots moved from prototypes to commercial tools, helping to fill labor shortages in aging populations and dangerous industries.
Today, in early 2026, humanoid robots are being used in real-world settings. At CES 2026, more than 35 models were displayed, indicating a quick move to commercialization. For instance, UBTECH delivered over 1,000 Walker S2 units to Chinese factories in 2025 for tasks like object manipulation and navigation.
Looking forward, humanoid robots are expected to play a significant role in society. By the late 2020s and into the 2030s, experts predict that 10–20 million units will be in use worldwide. This number could increase to 1–3 billion by 2050 as prices drop to $10,000-$25,000 per unit. Markets are expected to reach $38 billion by 2035 and possibly $5 trillion by 2050, with applications in manufacturing (30% share), logistics (25%), healthcare (20%), and households (15%).
Advancements in AI are bringing us closer to artificial general intelligence. This will enable adaptive learning. Lighter materials and biomechanics will offer near-human dexterity for tasks like eldercare, precise surgery, and disaster response. By 2030, these technologies could automate 30% of work hours in the U.S., impacting economies and city layouts. However, we need to tackle regulatory, ethical, and social challenges, such as job loss and safety standards. China is poised to lead in scale due to government support. Still, global collaboration could lead to a time when humanoids transition from being assistants to vital partners, fulfilling the age-old visions that started it all.
