The music heard when Elmer Fudd reads the robot's instruction manual was featured on the album "The Carl Stalling Project: Music From Warner Bros. Cartoons 1936-1958". It is part of the "Various Cues From Bugs Bunny Films" track.
The same robot was used by Sylvester hunting Speedy Gonzales in a 1964 cartoon, Nuts and Volts. The scene where the lower half of its body fell apart and parts fell out of its sockets like a person accidentally dropping its pants was also reused.
Carl Stalling put a futuristic spin on the familiar What's Up, Doc opening theme.
Bugs literally throws a monkey wrench (or a spanner, in Great Britain) into the robot's works. A popular phrase at the time was Don't throw a monkey wrench into things, meaning don't mess things up.
The rusted robot sight gag might have been inspired by the Tin Man scene in "The Wizard of Oz."
