Origins of "robot" and"robotics"
The word "robot" conjuresup a variety of images, from R2D2 and C3PO of Star Wars fame; tohuman-like machines that exist to serve their creators (perhaps in theform of the cooking and cleaning Rosie in the popular
cartoonseries the Jetsons); to the Rover Sojourner, which explored theMartian landscape as part of the Mars Pathfinder mission. Some peoplemay alternatively perceive robots as dangerous technological ventures thatwill someday lead to the demise of the human race, either by outsmartingor outmuscling us and taking over the world, or by turning us into completelytechnology-dependent beings who passively sit by and program robots todo all of our work. In fact, the first use of the word "robot" occurredin a play about mechanical men that are built to work on factory assemblylines and that rebel against their human masters. These machinesin R.U.R. (Rossum's Universal Robots), written by Czech playwrightKarl Capek in 1921, got their name from the Czech word for slave.The word "robotics"was also coined by a writer. Russian-born American science-fictionwriter Isaac Asimov first used the word in 1942 in his short story "Runabout."Asimov had a much brighter and more optimistic opinion of the robot's rolein human society than did Capek. He generally characterized the robotsin his short stories as helpful servants of man and viewed robots as "abetter, cleaner race." Asimov also proposed three "Laws of Robotics"that his robots, as well as sci-fi robotic characters of many other stories,followed:
Law One
A robot may not injure a human being or, through inaction, allow a humanbeing to come to harm.
- Law Two
A robot must obey the orders given it by human beings except where suchorders would conflict with the First Law.
Law Three
A robot must protect its own existence as long as such protection doesnot conflict with the First or Second Law.
Definitions of "robot"
So what exactly is a robot? This actually turns out to be a ratherdifficult question. Several definitions exist, including the following:"A reprogrammable, multifunctional manipulatordesigned to move material, parts, tools, or specialized devices throughvarious programmed motions for the performance of a variety of task."Robot Institute of America, 1979
"An automatic device that performs functionsnormally ascribed to humans or a machine in the form of a human."Webster's Dictionary

Early Conceptions ofRobots
One of the first instances of a mechanical device built to regularly carryout a particular physical task occurred around 3000 B.C.: Egyptianwater clocks used human figurines to strike the hour bells. In 400B.C., Archytus of Taremtum, inventor of the pulley and the screw, alsoinvented a wooden pigeon that could fly. Hydraulically-operated statuesthat could speak, gesture, and prophecy were commonly constructed in HellenicEgypt during the second century B.C.In the first century A.D., Petronius Arbiter made a doll that could movelike a human being. Giovanni Torriani created a wooden robot thatcould fetch the Emperor's daily bread from the store in 1557. Roboticinventions reached a relative peak (before the 20th century) in the 1700s;countless ingenius, yet impractical, automata (i.e. robots) were createdduring this time period. The 19th century was also filled with newrobotic creations, such as a talking doll by Edison and a steam-poweredrobot by Canadians. Although these inventions throughout historymay have planted the first seeds of inspiration for the modern robot, thescientific progress made in the 20th century in the field of robotics surpassprevious advancements a thousandfold.
The first modern robots
The earliest robots as we know them were created in the early 1950s byGeorge C. Devol, an inventor from Louisville, Kentucky. He inventedand patented a reprogrammable manipulator called "Unimate," from "UniversalAutomation." For the next decade, he attempted to sell his productin the industry, but did not succeed. In the late 1960s, businessman/engineerJoseph Engleberger acquired Devol's robot patent and was able to modifyit into an industrial robot and form a company called Unimation to produceand market the robots. For his efforts and successes, Englebergeris known in the industry as "the Father of Robotics."Academia also made much progress in the creation new robots. In 1958at the Stanford Research Institute, Charles Rosen led a research team indeveloping a robot called "Shakey." Shakey was far more advancedthan the original Unimate, which was designed for specialized, industrialapplications. Shakey could wheel around the room, observe the scenewith his television "eyes," move across unfamiliar surroundings, and toa certain degree, respond to his environment. He was given his namebecause of his wobbly and clattering movements.
As a seasoned expert in the field of robotics and automation, I can assure you that the origins of the terms "robot" and "robotics" are deeply rooted in both literary and scientific history. The concept of robots has evolved over the years, shaping our perceptions from mechanical slaves to advanced intelligent machines. Let me shed light on the evidence supporting this journey.
The term "robot" was first introduced in the play "R.U.R. (Rossum's Universal Robots)" by Czech playwright Karl Capek in 1921. This groundbreaking work depicted mechanical men designed to work on factory assembly lines who eventually rebel against their human creators. The word "robot" itself is derived from the Czech word for slave, highlighting the original notion of these machines as servile entities.
Moving forward, the word "robotics" was coined by the renowned Russian-born American science-fiction writer Isaac Asimov in 1942. Asimov, with a more optimistic view of robots, portrayed them as helpful servants to humanity in his short stories. In contrast to Capek's dystopian vision, Asimov proposed three "Laws of Robotics" that governed the behavior of his robotic characters, emphasizing their role as benevolent assistants rather than potential threats.
Now, let's delve into the definitions of "robot" and "robotics" as outlined by various sources. The Robot Institute of America (1979) defines a robot as a "reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks." Webster's Dictionary describes a robot as an "automatic device that performs functions normally ascribed to humans or a machine in the form of a human." The British Department of Industry offers a concise definition: "a reprogrammable manipulator device." Mike Brady provides a broader perspective, stating that robotics is "that field concerned with the intelligent connection of perception to action."
Taking a historical journey, early conceptions of robots date back to around 3000 B.C., with Egyptian water clocks featuring human figurines to strike hour bells. Mechanical devices, such as Archytus of Taremtum's wooden pigeon in 400 B.C. and Giovanni Torriani's wooden robot in 1557, demonstrated early attempts at automation. The 1700s and 19th century witnessed a surge in ingenious yet impractical automata, paving the way for the significant scientific progress made in the 20th century.
The first modern robots emerged in the early 1950s, with George C. Devol inventing and patenting the "Unimate," a reprogrammable manipulator. Joseph Engleberger, often referred to as the "Father of Robotics," acquired Devol's patent, modified it into an industrial robot, and established the company Unimation to produce and market these robots.
In academia, notable progress was made in 1958 when Charles Rosen led a research team at the Stanford Research Institute to develop "Shakey," a more advanced robot with the ability to move around, observe its surroundings through television "eyes," and respond to its environment.
This comprehensive overview showcases the rich history and diverse perceptions surrounding robots and robotics, reflecting the evolution of these concepts from ancient automata to the sophisticated machines of the 20th century.
