The word Robot comes from the Slavic word robota, which means labour/work.
Robotics is one branch of artificial intelligence which is now widely used in factories to perform high-precision jobs such as welding and riveting. They are also used in special situations that would be dangerous for humans — for example, in cleaning toxic wastes or defusing bombs.
Since the great advances have been made in the field of robotics during the last decade. They are becoming the helpers for the human.
The term robotics was introduced by writer Isaac Asimov, when he was thinking about androids, he envisioned a world where these human-like robots would act like servants and would need a set of programming rules to prevent them from causing harm. But in the 75 years since the publication of the first story to feature his ethical guidelines, there have been significant technological advancements. We now have a very different conception of what robots can look like and how we will interact with them, In his science fiction book I, Robot, published in 1950, he presented three laws of robotics:
1. A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
Asimov later added the “Zeroth Law,” above all the others – “A robot may not harm humanity, or, by inaction, allow humanity to come to harm.”
The Three Laws are what makes sure that we have good robots.
So, in Asimov’s robot stories, the Three Laws are not just a guarantee that the robots are good. They seem to indicate that there’s some connection between goodness and stability/sanity—or even between goodness and intelligence. That is, it’s impossible to be truly intelligent unless you’re truly good.
