Imagined by Isaac Asimov as soon as 1939, and written under their current form by John Campbell Jr. in 1950, the famous Three Laws of robotics are firmly ingrained in the positronic robot’s brains and have for objective to restrain their behaviour in order to avoid they harm human beings.
They can be written in the following manner:
- First Law: « A robot may not injure a human being, or, through inaction, allow a human being to come to harm. »
- Second Law: « A robot must obey the orders given it by human beings except where such orders would conflict with the First Law. »
- Third Law: « A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws. »
In 1985, in Robots and Empire, Isaac Asimov introduce a fourth law which supplant the other ones:
- Zeroth Law: « A robot may not injure humanity, or, through inaction, allow humanity to come to harm. »
