History of Humanoid Robotics
Let’s start in Ancient Greece with the emergence of automata, machines designed to complete tasks or mimic human actions.
Hero of Alexandria
In the first century, Hero of Alexandria creates several mechanical devices that can be considered early forms of robotic systems. He writes extensively on the pneumatics that power many of his inventions. He devises systems that animate machines using steam, water, and air pressure.
One of his most famous creations, the Automatic Theater, is a mechanical play that’s over 10 minutes long. It’s powered by a complex system of ropes, drums, and pulleys. Although not humanoid in form, it demonstrates the principles of programming and automation that would facilitate later developments in robotics.
Ancient China
Crafting automata is also part of Ancient Chinese culture with engineers like Zhang Heng and Ma Jun creating some of the world’s first known mechanical devices. Heng’s earthquake weathercock shows the direction of earthquakes while Jun creates a puppet theater with mechanical figurines performing various actions.
Ismael al Jazari
In the 1200s Ismael al Jazari completes The Book of Knowledge of Ingenious Mechanical Devices. It details a plethora of inventions including a humanoid robot waitress that chills and serves beverages.
Leonardo da Vinci
Around 1495, Leonardo da Vinci designs what many consider the first humanoid robot. It’s a mechanical knight capable of standing, sitting, moving its arms, and opening its visor with an elaborate system of pullies and cables.
Wolfgang von Kempelen
Around 1770 Wolfgang von Kempelen designs a fake chess playing machine that’s operated by a human hidden inside. It’s designed to appear as an autonomous robot playing chess against human opponents.
R.U.R.
In 1921 Karel Capek introduces the word robot into the lexicon with the play R.U.R., which stands for Rossum’s Universal Robots. It features artificial people called robots who can do any work real humans can.
Elektro
Westinghouse Electric Corporation introduces Elektro at the 1939 New York World’s Fair. It’s a humanoid robot that can walk by voice command, speak about 700 words via a record player, smoke cigarettes, blow up balloons, and move its head and arms.
The 1939 fair’s theme was The World of Tomorrow. Elektro was a hit at the fair, presented in the Westinghouse Pavilion as part of an exhibit called The Hall of Electrical Living.
Standing 2.1 meters (7 feet) tall, Elektro weighed 120 kg (265 lbs). Its aluminum build gave it a shiny, futuristic appearance. It operated using a series of relays and motors, controlled by electrical signals. The robotic system was powered via a tethered connection that limited its mobility. Commands were sent via a microphone and a push-button control panel that activated specific relays. Its speech came from a built-in phonograph that delivered up to 26 phrases.
Elektro’s leg motors powered simple bipedal locomotion. The robot moved its arms up and down, performed gestures, and held objects. It could raise its fingers one by one to count to 10. Its head could turn side to side. With its primitive photoelectric cells, Elektro could detect visual cues and respond to changes in light.
Grey Walter’s Tortoises
In the late 1940s, Neurophysiologist Grey Walter creates simple robots he calls tortoises. They demonstrate behavior like seeking light, charging themselves, and obstacle avoidance.
Unimate
In the early 60s, the first industrial robot, Unimate, starts work on a General Motors assembly line in New Jersey. Although not humanoid, it’s a significant step toward industrial automation using robotic technology.
WABOT-1
In the 1970s one of the first full-scale humanoid robots is developed at Waseda University in Japan. The WABOT-1 can communicate with people, measure distances and carry objects.

As North America’s largest automation trade association, A3 notes that the Chinese government is determined to dominate humanoid robotics by 2027.
The Future of Humanoid Robotics
2030s
By 2030, the humanoid robotics market is expected to reach nearly 80 billion dollars. Emergen Research predicts a compound annual growth rate of 62.5%.
Thanks to rapid advancements in artificial intelligence and machine learning, humanoid robots in the 2030s exhibit higher levels of autonomy and intelligence. Breakthroughs in material science and mechatronics enable greater mobility and dexterity.
Humanoid robots are more tightly integrated with disaster planning. Their ability to navigate debris and hazardous environments is refined so rescuers can save more lives during fires, earthquakes and other emergencies.
In healthcare settings, their presence is increasingly normal. Advanced robots serve as companions and caretakers for the elderly and disabled. Specialized humanoids come equipped with advanced sensors to monitor vital signs and emotional states to improve personalized care.
At this point, humanoids are more accessible than ever but the cost is still out of reach for most. Humanoid robot ownership becomes a status symbol. Some consumers spend more on personal humanoid robots than they would a car. They do household chores, interact with home systems, organize schedules and more.
They’re not recommended for homes with children but people do it anyway.
As natural language processing and emotional AI evolve, the place for humanoid robots in daily life becomes increasingly evident.
2040s
In the 2040s, advances in materials science and bioengineering make robots with skin-like textures and other lifelike features. Humanoids with realistic hair, eyes, and other highly detailed attributes mimic human expressions and subtle facial movements precisely.
The priciest ones perform fluid, natural movements rather than the stereotypical robotic motions of the past.
Ownership becomes more widespread thanks to a bustling aftermarket economy and copycat manufacturers.
With near seamless integration with human activities, the robots of the 40s are effective in roles ranging from personal assistants to hospitals to public safety. Humanoid robots exhibit advanced emotional intelligence so they can detect and appropriately respond to human needs.
Jobs most at risk during this rise of humanoid robots include receptionists, cashiers, nursing assistants, frontline manufacturing workers, food servicepeople and security guards.
2050s
In the 2050s, the most advanced humanoid robots are nearly indistinguishable from real people. Due to costs, the cutting-edge tech is only available to advanced militaries and the super wealthy.
Conspiracy theories thrive about celebrities who fans suspect have been swapped out by humanoids. When a humanoid makes it to the final round of a popular reality dating show, calls for transparency in robotics grow.
Advanced biometric systems emerge as the standard for differentiating robots from people. They use unique biological markers that robots can’t replicate like detailed DNA analysis and complex retina scans.
Legal requirements emerge for embedded identification systems in robotics. By the close of the decade, digital markers are required in code to clearly identify bots as non-human.
2060s
By the 2060s, state-of-the-art humanoid robots exhibit behaviors and cognitive functions that mimic sentience. Whether they’re capable of experiences and feelings is a matter of intense debate. People are divided about the moral status of artificial beings.
Mass production and refurbishing of humanoids makes useful robots widely available to the public. The most advanced models, however, remain out of reach to most. As robotics become more advanced, so too do methods for hacking and bypassing security measures.
Bad actors leverage AI driven techniques to forge biometric data and hack into robot identification systems. Security technologies also evolve to keep up with real-time behavioral analysis, anomaly detection and advanced cryptography to ensure robots can’t escape detection.
2070s
In the 2070s, digital twins are used to create precise robotic replicas of individuals. Not only do they reflect their human counterparts in real-time, they also act the same, with the ability to filter out the more unsavory bits. The robotic doubles handle personal and professional commitments.
More controversially, the wealthiest families maintain digital twins of themselves so their replicas can prosper after death. One of the few people who can afford the technology is Maxwell Sterling, a popular Congressman planning a run for president.
He’s the first presidential candidate in history to use a robotic double on the campaign trail. At 107, he’s also one of the oldest people to ever run for president.
He wins resoundingly with the help of his double who remains a secret to the public.
When his approval rating is at its highest, halfway through his first term, records leak revealing the real Maxwell Sterling died weeks before the general election.
Congress is in disarray. Matters get even more confusing when polling shows only a minor dip in support for President Sterling.
After much arguing it’s clear: A humanoid robot will probably be re-elected in 2076.
