Carnegie Mellon University has inducted four famous robots into its newly established Robot Hall of Fame.
Four machines are to be honoured in the first ceremony, including Nasa's Mars Pathfinder Microrover Flight Experiment, better known as 'Sojourner'.
The other winners are Unimate, the first industrial robot, and fictional automata R2-D2 from the Star Wars films and the evil HAL-9000 from 2001: A Space Odyssey.
The robots' creators, or others close to them, will accept certificates in their honour.
Carnegie Mellon said that its Robot Hall of Fame was established to honour noteworthy robots, both real and fictional, along with their creators in recognition of the increasing benefits such inventions are bringing to society.
The Robot Hall of Fame website is also now live.
