What do you mean by robotics?
The Origin and Meaning of Robotics
The term “robotics” originates from the word “robot,” first introduced in a 1920 play by Czech writer Karel Čapek. Derived from the Slavic word robota, meaning “worker,” a robot is a computer-controlled machine capable of performing complex tasks. Isaac Asimov coined “robotics” in 1941, defining three laws for robot behavior that influence modern robot ethics. Robots simulate human abilities with artificial intelligence and programmable systems, enhancing their versatility in performing tasks.
