For almost 100 years robots have been part of our collective perception of the future, and are now part of our actual present. As you will see from this list of famous robots our visions of these metal machines are as varied as the colors in a box of crayons.
C3PO and R2D2 from Star Wars
Marvin the very depressed robot from the great
book The Hitchhiker's Guide To The Galaxy
Robocop the cyborg, from Robocop the movie.
