Clepsydra 1400 BC Babylonians develop the clepsydra, a clock that measures time using the flow of water. It's considered one of the first "robotic" devices in history. For centuries, inventors will refine the design. Around 270 BC, the Greek inventor Ctesibius becomes famous for a water clock with moving figures on it.
Aristotle’s Idea 322 BC The Greek philosopher Aristotle imagines the great utility of robots, writing, "If every tool, when ordered, or even of its own accord, could do the work that befits it … then there would be no need either of apprentices for the master workers or of slaves for the lords."

Asimov’s Three Laws of Robotics 1942 American science fiction author Isaac Asimov publishes a short story, "Runaround," that introduces the "Three Laws of Robotics"--rules that every robot is programmed to obey: 1. A robot may not harm a human being, or, through inaction, allow a human being to come to harm. 2. A robot must obey the orders given to 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.
Universal Automation 1954 Industrial robotics pioneer George Devol files a patent (pictured) for the first programmable robot and coins the term "universal automaton."

MIT Ashtray 1959 The Servomechanisms Laboratory at the Massachusetts Institute of Technology demonstrates computer-assisted manufacturing. A robotic milling machine creates a commemorative ashtray for each attendee .
Unimate 1961 Unimate, the world's first industrial robot, goes to work on a General Motors assembly line.
Rosie the Robot 1962 Rosie the robot appears on The Jetsons, an animated TV program about a family from the future. The iconic house maid becomes one of the best-known robot characters in recent history.
Shakey 1966 The Artificial Intelligence Center at the Stanford Research Center begins development of Shakey, the first mobile robot. It is endowed with a limited ability to see and model its environment and is controlled by a computer that fills an entire room .
HAL 1968 HAL 9000 ( H euristically programmed AL gorithmic computer) appears in the Stanley Kubrick film 2001: A Space Odyssey, written by Arthur C. Clarke. The artificially intelligent computer runs the spaceship Discovery--and eventually goes berserk. The character reflects concern about the increasing power of intelligent machines over man.

Dante 1993 An eight-legged robot named Dante attempts to explore Antarctica's Mount Erebus volcano. It is remotely controlled from the U.S. and collects a small amount of data before mechanical difficulties end the experiment. But the landmark effort ushers in a new era of robotic exploration of hazardous environments.
Furby 1998 A fuzzy, batlike robot called Furby becomes the must-have toy of the holiday season. The $30 toys seemingly "evolve" over time, first speaking in gibberish but soon developing the use of preprogrammed English phrases. More than 27 million of the toys sell in a 12-month period.
Aibo 1999 Gadget lovers develop a serious case of puppy love for Sony's robot dog AIBO. The $2,000 mechanical mutt can navigate around a room and respond to a set of limited commands.
