15907 Robot           Discovered 1997 Oct. 6 by P. Pravec at Ondřejov.
The word "robot" was invented by Czech writer Josef Čapek for an artificial man in the famous play R. U. R. ("Rossum's Universal Robots") written by his brother Karel Čapek in 1920. Later it became a general term used for automated devices of various kinds.
