An android is a humanoid robot[1] or synthetic organism[2][3][4] designed to look and act like a human, especially one with a body having a flesh-like resemblance.[2] Historically, androids remained completely within the domain of science fiction where they are frequently seen in film and television. Only recently have advancements in robot technologyallowed the design of functional and realistic humanoid robots.[5] However, it is important to note, these androids nowhere match their television or film counterparts.Contents
Etymology
The word was coined from the Greek root ἀνδρ- 'man' (male, as opposed to anthrop- = human being) and the suffix -oid 'having the form or likeness of';[6] while the term 'android' is used in reference to humanoid robots in general, a robot that is given a female appearance is technically a 'gynoid'.The Oxford English Dictionary traces the earliest use (as "Androides") to Ephraim Chambers' Cyclopaedia, in reference to an automaton that St. Albertus Magnus allegedly created.[3][7]The term "android" appears in US patents as early as 1863 in reference to miniature human-like toy automatons.[8] The term android was used in a more modern sense by the French author Auguste Villiers de l'Isle-Adam in his work Tomorrow's Eve (1886).[3] This story features an artificial humanlike robot named Hadaly. As said by the officer in the story, "In this age of Realien advancement, who knows what goes on in the mind of those responsible for these mechanical dolls." The term made an impact into English pulp science fictionstarting from Jack Williamson's The Cometeers (1936) and the distinction between mechanical robots and fleshy androids was popularized by Edmond Hamilton's Captain Future(1940–1944).[3]
Although Karel Čapek's robots in R.U.R. (Rossum's Universal Robots) (1921)—the play that introduced the word robot to the world—were organic artificial humans, the word "robot" has come to primarily refer to mechanical humans, animals, and other beings.[3] The term "android" can mean either one of these,[3] while a cyborg ("cybernetic organism" or "bionic man") would be a creature that is a combination of organic and mechanical parts.
The term "droid", popularized by George Lucas in the original Star Wars film and now used widely within science fiction, originated as an abridgment of "android", but has been used by Lucas and others to mean any robot, including distinctly non-human form machines like R2-D2. The word "android" was used in Star Trek: The Original Series episode "What Are Little Girls Made Of?" The abbreviation "andy", coined as a pejorative by writer Philip K. Dick in his novel Do Androids Dream of Electric Sheep?, has seen some further usage, such as within the TV series Total Recall 2070.[9]
Authors have used the term android in more diverse ways than robot or cyborg. In some fictional works, the difference between a robot and android is only their appearance, with androids being made to look like humans on the outside but with robot-like internal mechanics.[3] In other stories, authors have used the word "android" to mean a wholly organic, yet artificial, creation.[3] Other fictional depictions of androids fall somewhere in between.[3]
Eric G. Wilson, who defines androids as a "synthetic human being", distinguishes between three types of androids, based on their body's composition:
- the mummy type - where androids are made of "dead things" or "stiff, inanimate, natural material", such as mummies, puppets, dolls and statues
- the golem type - androids made from flexible, possibly organic material, including golems and homunculi
- the automaton type - androids which are a mix of dead and living parts, including automatons and robots[4]
Projects
Several projects aiming to create androids that look, and, to a certain degree, speak or act like a human being have been launched or are underway.Japan

The Intelligent Mechatronics Lab, directed by Hiroshi Kobayashi at the Tokyo University of Science, has developed an android head called Saya, which was exhibited at Robodex 2002 in Yokohama, Japan. There are several other initiatives around the world involving humanoid research and development at this time, which will hopefully introduce a broader spectrum of realized technology in the near future. Now Saya is working at the Science University of Tokyo as a guide.
The Waseda University (Japan) and NTT Docomo's manufacturers have succeeded in creating a shape-shifting robot WD-2. It is capable of changing its face. At first, the creators decided the positions of the necessary points to express the outline, eyes, nose, and so on of a certain person. The robot expresses its face by moving all points to the decided positions, they say. The first version of the robot was first developed back in 2003. After that, a year later, they made a couple of major improvements to the design. The robot features an elastic mask made from the average head dummy. It uses a driving system with a 3DOF unit. The WD-2 robot can change its facial features by activating specific facial points on a mask, with each point possessing three degrees of freedom. This one has 17 facial points, for a total of 56 degrees of freedom. As for the materials they used, the WD-2's mask is fabricated with a highly elastic material called Septom, with bits of steel wool mixed in for added strength. Other technical features reveal a shaft driven behind the mask at the desired facial point, driven by a DC motor with a simple pulley and a slide screw. Apparently, the researchers can also modify the shape of the mask based on actual human faces. To "copy" a face, they need only a 3D scanner to determine the locations of an individual's 17 facial points. After that, they are then driven into position using a laptop and 56 motor control boards. In addition, the researchers also mention that the shifting robot can even display an individual's hair style and skin color if a photo of their face is projected onto the 3D Mask.

Prof Nadia Thalmann, a Nanyang Technological University scientist, directed efforts of the Institute for Media Innovation along with the School of Computer Engineering in the development of a social robot, Nadine. Nadine is powered by software similar to Apple’s Sirior Microsoft’s Cortana. Nadine may become a personal assistant in offices and homes in future, or she may become a companion for the young and the elderly.Assoc Prof Gerald Seet from the School of Mechanical & Aerospace Engineering and the BeingThere Centre led a three-year R&D development in tele-presence robotics, creating EDGAR. A remote user can control EDGAR with the user’s face and expressions displayed on the robot’s face in real time. The robot also mimics their upper body movements. [10]

Walt Disney and a staff of Imagineers created Great Moments with Mr. Lincoln that debuted at the 1964 New York World's Fair.[14]Hanson Robotics, Inc., of Texas and KAIST produced an android portrait of Albert Einstein, using Hanson's facial android technology mounted on KAIST's life-size walking bipedal robot body. This Einstein android, also called "Albert Hubo", thus represents the first full-body walking android in history (see video at[15]). Hanson Robotics, the FedEx Institute of Technology,[16] and the University of Texas at Arlington also developed the android portrait of sci-fi author Philip K. Dick (creator of Do Androids Dream of Electric Sheep?, the basis for the film Blade Runner), with full conversational capabilities that incorporated thousands of pages of the author's works.[17] In 2005, the PKD android won a first place artificial intelligence award from AAAI.
Use in fiction

Androids are a staple of science fiction. Isaac Asimov pioneered the fictionalization of the science of robotics and artificial intelligence, notably in his 1950s series I, Robot.[18] One thing common to most fictional androids is that the real-life technological challenges associated with creating thoroughly human-like robots—such as the creation of strong artificial intelligence—are assumed to have been solved.[19] Fictional androids are often depicted as mentally and physically equal or superior to humans—moving, thinking and speaking as fluidly as them.[3][19]The tension between the nonhuman substance and the human appearance—or even human ambitions—of androids is the dramatic impetus behind most of their fictional depictions.[4][19] Some android heroes seek, like Pinocchio, to become human, as in the films Bicentennial Man, Hollywood, Enthiran and A.I. Artificial Intelligence,[19] or Data in Star Trek: The Next Generation. Others, as in the film Westworld, rebel against abuse by careless humans.[19]Android hunter Deckard in Do Androids Dream of Electric Sheep? and its film adaptation Blade Runner discovers that his targets are, in some ways, more human than he is.[19]Android stories, therefore, are not essentially stories "about" androids; they are stories about the human condition and what it means to be human.[19]
One aspect of writing about the meaning of humanity is to use discrimination against androids as a mechanism for exploring racism in society, as in Blade Runner.[20] Perhaps the clearest example of this is John Brunner's 1968 novel Into the Slave Nebula, where the blue-skinned android slaves are explicitly shown to be fully human.[21] More recently, the androids Bishop and Annalee Call in the films Aliens and Alien Resurrection are used as vehicles for exploring how humans deal with the presence of an "Other".[22]
Female androids, or "gynoids", are often seen in science fiction, and can be viewed as a continuation of the long tradition of men attempting to create the stereotypical "perfect woman".[23] Examples include the Greek myth of Pygmalion and the female robot Maria in Fritz Lang's Metropolis. Some gynoids, like Pris in Blade Runner, are designed as sex-objects, with the intent of "pleasing men's violent sexual desires,"[24] or as submissive, servile companions, such as in The Stepford Wives. Fiction about gynoids has therefore been described as reinforcing "essentialist ideas of femininity",[25] although others have suggested that the treatment of androids is a way of exploring racism and misogyny in society.[26]
The 2015 Japanese film Sayonara, starring Geminoid F, was promoted as "the first movie to feature an android performing opposite a human actor".[27]
