Norman White's "The Helpless Robot"

Electronic media artist Norman White (1938) created many robot-based artworks. In "The Helpless Robot" (1987–2002), an electronically synthesized voice asks for the physical help of passers-by with a persuasive tone. Over time, the voice slowly changes to a more forceful, commanding tone, complaining when the assistance is not being executed properly.
