Robot: the story on HearLore | HearLore
Robot
The word robot was not invented by a scientist or an engineer, but by a painter and writer named Josef Čapek, who suggested it to his brother Karel for a 1920 play. Before this moment, the creatures in Karel Čapek's Rossum's Universal Robots were simply called workers or laborers, but the family needed a term that captured the essence of forced labor. Josef chose the Czech word robota, which meant forced labor or drudgery, a concept deeply rooted in the history of serfdom in the region. This single word choice would eventually define an entire field of technology and change how humanity viewed its own creations. The play itself depicted these mass-produced beings as efficient but emotionless, incapable of original thought, and indifferent to self-preservation, setting the stage for decades of ethical debate regarding artificial life. The story of the word's origin reveals that the very concept of the robot was born from a discussion about the exploitation of labor, not from a blueprint for a machine.
Ancient Dreams of Moving Metal
Long before the 20th century, human imagination had already conjured mechanical servants capable of speech and movement. In the 4th century BCE, Greek engineer Archytas described a steam-operated mechanical bird called The Pigeon, while Hero of Alexandria created numerous user-configurable automated devices powered by pneumatics and hydraulics. These ancient inventors built speaking automata and machines that could mimic life, yet they lacked the electronic brains that define modern robotics. In the 13th century, the polymath Ismail al-Jazari constructed a waitress automaton that could serve drinks from a reservoir tank, appearing from an automatic door to pour a cup of wine. His designs included a hand-washing automaton with a flush mechanism similar to modern toilets, demonstrating a sophisticated understanding of fluid dynamics and mechanical timing. In Japan, the 17th to 19th centuries saw the rise of karakuri ningyō, mechanical puppets used in theater and festivals that reenacted traditional myths without any human intervention. These early machines were not programmable in the digital sense, but they were the ancestors of the complex systems that would eventually replace human workers in dangerous environments.
The Tortoise That Found Its Way Home
In 1948, William Grey Walter of the Burden Neurological Institute in Bristol, England, created the first electronic autonomous robots with complex behavior, naming them Elmer and Elsie. These three-wheeled machines, often described as tortoises due to their shape and slow rate of movement, were capable of phototaxis, allowing them to find their way to a recharging station when their battery power ran low. Walter stressed the importance of using purely analogue electronics to simulate brain processes, a radical approach at a time when contemporaries like Alan Turing were turning towards digital computation. His work proved that rich connections between a small number of brain cells could give rise to very complex behaviors, essentially showing that the secret of how the brain worked lay in how it was wired up. This analog approach inspired subsequent generations of robotics researchers, including Rodney Brooks and Hans Moravec, and modern incarnations of Walter's turtles can still be found in the form of BEAM robotics. The story of these early tortoises highlights a fundamental shift in thinking: machines did not need to be programmed with every single action to be useful, but could instead react to their environment in ways that mimicked life.

When was the first electronic autonomous robot created?
William Grey Walter created the first electronic autonomous robots in 1948 at the Burden Neurological Institute in Bristol, England.

These robots used purely analogue electronics to simulate brain processes and could find their way to a recharging station.
When was the first commercially successful digital robot built?
George Devol built the first commercially successful digital and programmable robot in 1954 and called it the Unimate. He sold the first Unimate to General Motors in 1960, and it was installed in 1961 in a plant in Trenton, New Jersey. This machine replaced humans in performing repetitive and dangerous tasks like handling molten metal.
What is the name of the robot that learns by guidance without programming?
The robot named Baxter was introduced in 2012 and learns by guidance without requiring software engineers to program it. Any regular worker can teach Baxter how to perform a task by moving its hands in the desired motion and having Baxter memorize them. By 2014, 190 companies in the US had bought Baxters, which are being used commercially in the UK.
What is the fuel source of the autonomous military robot EATR?
The EATR robot can continually refuel itself using organic substances, including chicken fat, which it finds on battlefields or other local environments. This fuel source has generated public concerns over its autonomous capabilities. The development of unmanned combat air vehicles like the BAE Systems Mantis has further intensified the debate over autonomous military robots.

Devol sold the first Unimate to General Motors in 1960, and it was installed in 1961 in a plant in Trenton, New Jersey, to lift hot pieces of metal from a die casting machine and stack them. This machine replaced humans in performing repetitive and dangerous tasks, such as handling molten metal that could kill a worker in seconds. The Unimate was a stark contrast to the playful automata of the past; it was designed with an emphasis on stark functionality rather than expressive aesthetics. By 1963, the first palletizing robot was introduced by the Fuji Yusoki Kogyo Company, and in 1973, a robot with six electromechanically driven axes was patented by KUKA robotics in Germany. These early industrial robots laid the foundations of the modern robotics industry, proving that machines could be more accurate, reliable, and cost-effective than human labor. The adoption of these machines in factories marked the beginning of a new era where automation would dominate production lines, replacing manual tasks with digital precision.
The Singularity and The Fear
As robots have become more advanced and sophisticated, experts and academics have increasingly explored the questions of what ethics might govern robots' behavior and whether robots might be able to claim any kind of social, cultural, ethical, or legal rights. Vernor Vinge has suggested that a moment may come when computers and robots are smarter than humans, a concept he calls the Singularity, which may be somewhat or possibly very dangerous for humans. In 2009, experts attended a conference hosted by the Association for the Advancement of Artificial Intelligence to discuss whether computers and robots might be able to acquire any autonomy, and how much these abilities might pose a threat or hazard. They noted that some robots have acquired various forms of semi-autonomy, including being able to find power sources on their own and being able to independently choose targets to attack with weapons. The social impact of intelligent robots is subject of a 2010 documentary film called Plug & Pray, which explores the potential consequences of a future where machines make decisions that were once the sole domain of human judgment. The fear of the Singularity is not just about the technology itself, but about the loss of human control over the very systems we created to serve us.
The Robot That Teaches Itself
In 2012, a new robot named Baxter was introduced which learns by guidance, allowing a worker to teach Baxter how to perform a task by moving its hands in the desired motion and having Baxter memorize them. Unlike usual industrial robots that take extensive programs and coding to be used, Baxter needs no programming to operate, meaning no software engineers are needed to deploy it. Any regular worker could program Baxter and it only takes a matter of minutes, allowing it to perform multiple, more complicated tasks. This robot was designed to safely interact with neighboring human workers, and it stops if it detects a human in the way of its robotic arms, featuring prominent off switches. Intended for sale to small businesses, they are promoted as the robotic analogue of the personal computer, and by 2014, 190 companies in the US had bought Baxters, which are being used commercially in the UK. The introduction of Baxter represented a shift from rigid, pre-programmed machines to collaborative robots that could adapt to human needs and learn from direct interaction. This new breed of robot, known as a cobot, is designed to work alongside humans rather than replacing them, marking a significant evolution in the relationship between man and machine.
The War of the Machines
The use of robots in military combat raises ethical concerns, especially when such robots are given some degree of autonomous functions. The US Navy has funded a report which indicates that, as military robots become more complex, there should be greater attention to implications of their ability to make autonomous decisions. One robot in particular, the EATR, has generated public concerns over its fuel source, as it can continually refuel itself using organic substances, including chicken fat, which it finds on battlefields or other local environments. Manuel De Landa has noted that smart missiles and autonomous bombs equipped with artificial perception can be considered robots, as they make some of their decisions autonomously. This represents an important and dangerous trend in which humans are handing over important decisions to machines. The development of unmanned combat air vehicles, such as the BAE Systems Mantis, which can fly themselves, pick their own course and target, and make most decisions on their own, has further intensified the debate. The question of whether autonomous robots might be more humane than human soldiers, as they could make decisions more effectively, remains a contentious issue in the field of military robotics.
The Future of Soft Machines
Robots with silicone bodies and flexible actuators, such as air muscles and electroactive polymers, look and feel different from robots with rigid skeletons, and can have different behaviors. Soft, flexible, and sometimes even squishy robots are often designed to mimic the biomechanics of animals and other things found in nature, which is leading to new applications in medicine, care giving, search and rescue, food handling, and manufacturing. This field, known as soft robotics, is a newer branch of robotics that challenges the traditional notion of machines as rigid, metal structures. Researchers are also modeling the behavior of swarms of thousands of tiny robots, inspired by colonies of insects such as ants and bees, which together perform a useful task. Each robot is quite simple, but the emergent behavior of the swarm is more complex, and the whole set of robots can be considered as one single distributed system. This approach makes swarms more resistant to failure, as a single large robot may fail and ruin a mission, but a swarm can continue even if several robots fail. The future of robotics may not be in the form of humanoid giants, but in the form of soft, flexible, and collective systems that can adapt to the world in ways that rigid machines never could.
