Before Alexa and Siri: A Look Back at a Century of Robotic Advancements

George Steinmetz / Getty Images News via Getty Images

We live in a world where robots and robotic technology have become part of our everyday lives. While films such as “Metropolis” and television series like “The Twilight Zone” warned of a world in which our mechanical creations would enslave us, many of us could not envision a day without virtual personal assistants like Siri or the floor-cleaning robotic vacuum Roomba. 

Robots today can reason, feel emotions, make restaurant recommendations, grasp objects, perform all the tasks of a human butler, and even do ballroom dancing.

It was just over 100 years ago that we first heard the term robot. 24/7 Tempo has compiled a list of how technology — and our lives — have changed over 100 years of robots.  We reviewed information from NASA, Wired, and other tech publications to find examples of the most popular, important, ground-breaking, and innovative robotic inventions over the past century. 

The term robot comes from a 1921 play written by Czech playwright Karel Čapek and the word is derived from the Czech word “robota,” or forced labor, as done by serfs. Early representations of these mechanical beings depicted them as emotionless automatons created  to serve humanity.

It wasn’t until the 1939 New York World’s Fair that Westinghouse built a robot with a personality, who could tell jokes and smoke. Japanese inventors created the first robots that served as toys in the 1940s. They were wind-up toys at first and then became battery-operated, creating  lucrative possibilities for toy makers.

The first autonomous robots — who mimicked people and were able to avoid obstacles — arrived in the late 1940s. 

Industry began employing industrial robots in the 1950s as General Motors put them to work on assembly lines, using their hydraulic arms to do repeated tasks and perform jobs considered dangerous to humans. 

Robots have become an indispensable feature of space exploration. Apollo 15 was the first NASA mission to use a lunar rover in 1971. These are 30 NASA inventions we still use everyday.

Biped robots like P2 debuted in 1996. Such robots are able to walk stairs and push carts. Kismet, created at the Massachusetts Institute of Technology, is one of the first robots to perceive emotions and understand social cues.

Humans still fear robots will replace them in every endeavor and make people obsolete, particularly in the workplace. But those concerns have diminished as robots have played key roles in oceanic and space exploration, boosted productivity in industry, and helped us perform daily tasks.  

1. R.U.R.
> Year: 1921
> Made by: Karel Čapek

R.U.R. refers to the play “Rossum’s Universal Robots,” written by Czech playwright Karel Čapek. The word robot comes from the Czech word “robota,” or forced labor, and is derived from the Slavic root word “rab,” meaning slave.


2. Eric
> Year: 1928
> Made by: William H. Richards and A.H. Reffell

One of the world’s first actual robots, Eric was created as a stand-in for Queen Elizabeth’s father, the Duke of York. The royal was supposed to officially open the Royal Horticultural Halls, but one of the robot’s makers, William H. Richards, thought that a show he considered to be mechanical should be opened by a mechanical man.

3. Gakutensoku
> Year: 1929

12. Rock ’em Sock ’em Robots
> Year: 1966
> Made by: Mattel

A must-have for kids growing up in the 1960s, this toy pitted two robots in a boxing ring. If one robot was skilled enough to land a sock to the jaw, the head of the opponent would spring upward, ending the match. It was introduced in 1964 by Mattel and is still popular.

13. Apollo 15 Lunar Rover
> Year: 1971
> Made by: NASA

Apollo 15 was the first NASA mission to employ a lunar rover in 1971. Astronauts David Scott and James Irwin assembled the 460-pound vehicle and drove it almost 17 miles while conducting experiments on the moon. They left the rover on the moon, one of three rovers still on the moon.
