  • 34CHAPTERRobotics andartificial intelligenceA ROBOT IS A SOPHISTICATED MACHINE, OR A SET OF MACHINES WORKING together, that performs certain tasks. Some people imagine robots as having two legs, ahead, two arms with functional end effectors (hands), an artificial voice, and an elec-tronic brain. The technical name for a humanoid robot is android. Androids are withinthe realm of technological possibility, but most robots are structurally simpler than, anddon’t look or behave like, people.An electronic brain, also called artificial intelligence (AI), is more than mere fic-tion, thanks to the explosive evolution of computer hardware and software. But eventhe smartest computer these days would make a dog seem brilliant by comparison.Some scientists think computers and robots might become as smart as, or smarter than,human beings. Others believe the human brain and mind are more complicated thananything that can be duplicated with electronic circuits.Asimov’s three lawsIn one of his early science-fiction stories, the famous author Isaac Asimov first men-tioned the word robotics, along with three “fundamental rules” that all robots oughtto obey:• First Law: A robot must not injure, or allow the injury of, any human being.• Second Law: A robot must obey all orders from humans, except ordersthat would contradict the First Law.• Third Law: A robot must protect itself, except when to do so would con-tradict the First Law or the Second Law.644Copyright © 2002, 1997, 1993 by The McGraw-Hill Companies.
