Android

An android, sometimes called just "droid" for short, was a humanoid robot or, as the Tenth Doctor once explained to Martha Jones, a "humanoid automaton". (PROSE: The Last Dodo) Examples included Kamelion (in his natural form) (TV: The King's Demons) and the K1 robot. (TV: Robot) Although the term "android" was often used for robots of both genders, a female android was technically called a "gynoid", and they were referred to as such on occasion. (PROSE: Christmas on a Rational Planet)

The Twelfth Doctor noted droids always spoke without abbreviating words. (TV: Deep Breath)

History
In the 1880s, Joseph Montague invented the Difference Golems. He used a research probe for the brain of the androids. (AUDIO: Children of Steel)

After seeing seven chair legs in the attic of 10 Downing Street in July 1900, Vicki Pallister wondered if there were wooden androids in Victorian London. However, she did not ask the Doctor if this was the case as she thought that it was probably something that she was supposed to already know. (AUDIO: Upstairs)

By the early 26th century, androids were commonplace in Earth Empire society, but were viewed as an under-class. The Orion androids finally became fed up with the situation and moved en masse to the relatively unused Orion System. They set up their own government, with the stipulation that humans living in the system could stay if they accepted android rule. The Earth Empire considered this a violation of sentient rights, and attacked, starting the Orion War. The Earth Military tried to use Cybermen against the androids, which eventually resulted in the Cyber-Wars. (AUDIO: Sword of Orion)

In the 40th century, androids were considered equal to humans. (AUDIO: The Guardian of the Solar System) At least one, Mark Seven, served in the Space Security Service. (AUDIO: The Destroyers)

River Song claimed to have dated androids. She said that they were "rubbish". (TV: Silence in the Library)

The Steigertrudes once used android replicas as part of a scheme. (PROSE: The Scarlet Empress)
