History of Robots
From the first industrial arm bolted to a General Motors assembly line in 1961 to today's AI-native humanoids entering commercial production—the story of robots is the story of humanity learning to build itself.
Where It All Began
The word "robot" entered the English language in 1920, coined by Czech playwright Karel Čapek in R.U.R. (Rossum's Universal Robots). It comes from the Czech robota—forced labor. But the impulse to build artificial workers is far older. Ancient Greeks described mechanical birds, Hero of Alexandria built automated temple doors, and Al-Jazari designed programmable humanoid musicians in 13th-century Mesopotamia.
The modern robotics industry traces its origin to a single patent. In 1954, inventor George Devol filed for a "Programmed Article Transfer" device—a digitally controlled robotic arm. He partnered with engineer Joseph Engelberger to found Unimation, the world's first robotics company. In 1961, their Unimate robot began pulling die castings from a molten metal press at a General Motors plant in New Jersey. Industrial robotics was born.
Over the six decades that followed, robots spread from automotive plants to hospitals, warehouses, farms, and outer space. Each era brought new capabilities: AI reasoning in the 1960s, bipedal locomotion in the 1970s, autonomous navigation in the 1990s, mass-market consumer robots in the 2000s. Today, the convergence of large language models and physical AI is opening another threshold: robots that can understand instructions, generalize to new tasks, and operate in the unstructured complexity of the real world.
Key Milestones
Eight moments that defined what robots are and what they can become.
Unimate — First Industrial Robot Arm
The Unimate #001 began operation on a General Motors assembly line in Trenton, New Jersey, performing spot welding and die casting. Invented by George Devol and commercialized by Joseph Engelberger, it marked the dawn of industrial robotics and proved that machines could replace humans in dangerous, repetitive factory work.
Shakey — First Mobile Robot with AI
Shakey was the first general-purpose mobile robot that could reason about its own actions. Using a camera, sonar, and bump sensors, it could navigate a multi-room environment, push objects, and plan routes—integrating perception, planning, and execution into a single system. Shakey pioneered algorithms that still underlie autonomous robots today.
WABOT-1 — First Full-Scale Humanoid
WABOT-1 was the world's first full-scale anthropomorphic robot. It could walk on two legs, grip objects with its hands, communicate in Japanese, and measure distances with its eyes. Built by Professor Ichiro Kato's team, it launched Japan's humanoid robotics tradition and proved that a machine could take on human form and basic human functions.
Sojourner — First Mars Rover
Part of the Mars Pathfinder mission, Sojourner became the first wheeled vehicle to operate on another planet. Weighing just 10 kg, it traveled 100 meters across Martian terrain, analyzed rocks, and transmitted more than 500 photographs. It demonstrated that remotely operated robots could extend scientific reach beyond Earth—a capability that shaped every Mars mission that followed.
ASIMO — Honda's Advanced Bipedal Robot
After 14 years of secret development, Honda unveiled ASIMO—the Advanced Step in Innovative Mobility. Standing 1.3 meters tall, ASIMO could walk, run at 6 km/h, climb stairs, open doors, and recognize faces and voices. It remained the most capable humanoid robot in the world for nearly a decade and became a global symbol of what robotics could achieve.
Roomba — First Mass-Market Home Robot
iRobot's Roomba was the first consumer robot to achieve genuine mass adoption. Priced at $199 and capable of cleaning floors autonomously, it crossed into mainstream households and redefined what "robot" meant to the public. By 2022 over 40 million Roombas had been sold, making it the best-selling autonomous consumer robot in history and proving the home-robot market was real.
Atlas — Boston Dynamics' Humanoid
Originally built for DARPA's Robotics Challenge, Atlas became the standard-bearer for humanoid agility. Over successive generations it learned to run, jump, do backflips, climb rubble, and manipulate objects. Atlas demonstrated that hydraulic and then electric actuation could produce human-like dynamic movement—shocking the robotics world with capabilities that seemed impossible only years earlier.
The AI Robot Era — Figure, 1X, Tesla Optimus
The convergence of large language models, vision transformers, and neural motion policies launched a new era. Figure AI, 1X Technologies, Tesla Optimus, Agility Robotics, Apptronik, and dozens of others raised billions to build general-purpose humanoids. For the first time, robots could follow natural-language instructions, generalize to new tasks without explicit programming, and operate in unstructured real-world environments.

Why the History of Robots Matters Now
Understanding the history of robots is not just academic. Every major shift in robotics has been preceded by a period that looked like stagnation—and then broken open by a new enabling technology. The transistor enabled digital control. Microprocessors made reprogrammable robots economical. The internet enabled fleet-scale deployment. Deep learning solved perception. Large language models are now tackling reasoning and task generalization.
Each generation of robots expanded the space of tasks machines could perform. Industrial arms replaced humans in hazardous, repetitive manufacturing. Surgical robots extended a surgeon's precision to sub-millimeter scale. Mars rovers extended human scientific reach to other worlds. The current generation of AI-native robots is attempting something more ambitious: replacing humans in the general-purpose, unstructured physical tasks that make up the bulk of economic labor.
Whether general-purpose robotics arrives in five years or fifteen, the history makes clear that the arc is consistent: robots begin as curiosities, become industrial tools, become consumer products, and finally become ambient infrastructure. The Roomba—once a novelty—is now an expected appliance. The humanoid robot is on the same trajectory. History is the best guide to where it's going.
Frequently Asked Questions
What was the first robot ever made? ▾
The first programmable industrial robot was Unimate, installed at a General Motors plant in 1961. It was invented by George Devol and commercialized by Joseph Engelberger through their company Unimation. However, mechanical automata (precursors to robots) date back much further—the ancient Greeks built automated machines, and Jacques de Vaucanson's Digesting Duck (1737) is often cited as a landmark in automation history.
When was the word "robot" first used? ▾
The word "robot" was first used in 1920, coined by Czech playwright Karel Čapek in his play R.U.R. (Rossum's Universal Robots). It comes from the Czech word "robota," meaning forced labor or drudgery. The play depicted artificial workers who eventually rebel against their human masters—a theme that has influenced science fiction ever since.
What robot is considered the most advanced today? ▾
This depends on the domain. For humanoid agility, Atlas (Boston Dynamics) and the latest generation of AI-native humanoids from Figure, 1X, and Agility Robotics represent the frontier.
