Dr. Charlotte Widnar (born August 3010) is a naturalist from the Robot Planetoid, who was created by Professor Farnsworth in August of 3010. She discovered the amazing, non-mecanical man, Homo farnsworth.
A fully evolved, sentient, humanlike robot scientist, Dr. Widnar had theorized carbon-based lifeforms could exist, but until the day she met the Planet Express crew, she never had any proof. She took them to the Museum of Natural Robo-History, where the Professor gave a speech. However, when he revealed that he invented the Nanobots in the first place, the doctor felt disappointed and left the building. She probably went to another planet. Bender Bending Rodríguez likely hit on her.
- Her first name Charlotte is the female form of Charles and her last name is an anagram of Darwin. Both are a reference to Charles Darwin, a naturlist who proposed the theory of evolution.
