Unit 47

Unit 47 is a female Robot who collaborated with Professor Farnsworth as a chemist working to create a virus that would destroy an infestation of posies in his youth and became his robosexual lover.

Leaving the Professor
Unit 47 eventually left the Professor for another Robot after 43 years together. These events left him loathing the idea of robosexuality, leading to his objection against Proposition ∞ in July 3010. Farnsworth claimed, for many years, that it was the departure of a female Human named Eunis what turned him against robosexuality, but he finally admitted that she was in fact a Robot during the debate led by George Takei's head.
