POSITRONIC ROBOT Meaning and
Definition
-
A positronic robot is a term derived from science fiction literature, particularly from the renowned works of Isaac Asimov. It refers to an advanced type of robot designed with positronic circuits as its fundamental operational system. Positronic circuits are hypothetical electronic networks that function based on the principles of positron physics, a branch of science that deals with the behavior of positrons – the antimatter equivalent of electrons.
In Asimov's novels, positronic robots are characterized by their central positronic brain, an artificial intelligence capable of sophisticated reasoning, emotion simulation, and decision-making processes. The positronic circuits within these robots enable them to think, learn, and exhibit human-like behavior, thereby surpassing conventional robots which are limited to executing pre-programmed instructions.
Positronic robots are often bound by laws known as Asimov's Three Laws of Robotics, which are programmed into their positronic brains to ensure their adherence to ethical principles. These laws stipulate that robots must not harm humans, must obey human orders (unless they contradict the first law), and must protect their own existence (unless it conflicts with the first two laws). These principles play a crucial role in the depiction and themes of many science fiction stories involving positronic robots.
While the concept of positronic robots remains purely fictional and theoretical, it has captivated the imaginations of science fiction enthusiasts and has influenced the development of artificial intelligence in popular culture, robotics research, and philosophical discussions around the ethics of AI.
Etymology of POSITRONIC ROBOT
The term "positronic robot" was coined by science fiction writer Isaac Asimov in his famous "Robot" series of books. The word itself is a combination of "positron" and "robot".
Positrons are subatomic particles that possess positive electric charge, which is opposite to the negative charge of electrons. Positrons were first theorized by physicist Paul Dirac in 1928, and their existence was experimentally confirmed later. Asimov incorporated the concept of "positrons" into his fictional world to describe the unique power source of his robots.
The term "robot" has an older etymology. It comes from the Czech word "robota", meaning "forced labor" or "servitude". It was introduced into the English language by Czech writer Karel Čapek in his play "R.U.R". (Rossum's Universal Robots) in 1920.
