2. Historical Roots of Robotics

2.1. The Origin of the Term “Robot”

The word “robot” originated from the Czech word “robota,” meaning forced labor or servitude. Czech writer Karel Čapek popularized the term in his 1920 play, Rossum’s Universal Robots (R.U.R.), where artificial beings performed labor for humans.

2.2. Isaac Asimov and the Three Laws of Robotics

Science fiction author Isaac Asimov is credited with coining the term “robotics.” He also introduced the “Three Laws of Robotics,” which have significantly influenced the ethical considerations in robotics:

A robot may not injure a human being or, through inaction, allow a human being to come to harm.
A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

These laws, though fictional, provide a framework for ensuring that robots operate in a way that benefits humanity.
