Where Does the Word “Robotics” Come From?

The history of the word “robotics” reflects how the field developed from a literary idea into a recognized branch of science and engineering.

The word “robot“ comes from the Czech word robota, meaning forced labor or compulsory work.

It first appeared in Karel Čapek’s 1920 play R.U.R. (Rossum’s Universal Robots), where artificial workers performed tasks for humans.

The term “robotics“ later became popular through science fiction author IsaacAsimov, who used it to describe the science and study of robots.

Today, robotics refers to the multidisciplinary field that combines engineering, electronics, computer science, and artificial intelligence to design, build, and improve robotic systems used across many industries.

What Is a Robot?

A robot is a programmable machine designed to complete tasks with limited or no direct human control.

While robots come in different shapes and sizes, they generally include mechanical parts, sensors, control systems, and software that allow them to perform specific functions.

Some robots are built for simple repetitive activities, while others are designed to adapt to changing situations using artificial intelligence.

For example, a factory robot may repeatedly assemble parts, while an autonomous robot may analyze its surroundings and choose how to move safely.

Common examples of robots include:

• Industrial Robots: Machines used for manufacturing, welding, assembly, and packaging.
