An Actroid at Expo 2005 in Aichi

An Actroid is a humanoid robot with strong visual human-likeness developed by Osaka University and manufactured by Kokoro Company Ltd. (the animatronics division of Sanrio). It was first unveiled at the 2003 International Robot Exposition in Tokyo, Japan. Several different versions of the product have been produced since then. In most cases, the robot's appearance has been modeled after an average young woman of Japanese descent.

The Actroid is a pioneer example of a real machine similar to imagined machines called by the science fiction terms android or gynoid, so far used only for fictional robots. It can mimic such lifelike functions as blinking, speaking, and breathing. The "Repliee" models are interactive robots with the ability to recognise and process speech and respond in kind. Science fiction is a form of speculative fiction principally dealing with the impact of imagined science and technology, or both, upon society and persons as individuals. ...

Technology

Internal sensors allow Actroid models to react with a natural appearance by way of air actuators placed at many points of articulation in the upper body. Early models had 42 points of articulation, later models have 47. So far, movement in the lower body is limited. The operation of the robot's sensory system in tandem with its air powered movements make it quick enough to react to or fend off intrusive motions, such as a slap or a poke. Artificial intelligence possessed by the android gives it the ability to react differently to more gentle kinds of touch, such as a pat on the arm. AI redirects here. ...

The Actroid can also imitate human-like behavior with slight shifts in position, head and eye movements and the appearance of breathing in its chest. Additionally, the robot can be "taught" to imitate human movements by facing a person who is wearing reflective dots at key points on their body. By tracking the dots with its visual system and computing limb and joint movements to match what it sees, this motion can then be "learned" by the robot and repeated.

The skin is composed of silicone and appears highly realistic. The compressed air that powers the robot's servo motors, and most of the computer hardware that operates the A.I., are external to the unit. This is a contributing factor to the robot's lack of locomotion capabilities. When displayed, the Actroid has always been either seated or standing with firm support from behind. Not to be confused with the element silicon. ... AI redirects here. ...

The interactive Actroids can also communicate on a rudimentary level with humans by speaking. Microphones within those Actroids record the speech of a human, and this sound is then filtered to remove background noise - including the sounds of the robot's own operation. Speech recognition software is then used to convert the audio stream into words and sentences, which can then be processed by the Actroid's A.I. A verbal response is then given through speakers external to the unit.

Further interactivity is achieved through non-verbal methods. When addressed, the interactive Actroids use a combination of "floor sensors and omnidirectional vision sensors" in order to maintain eye contact with the speaker. In addition, the robots can respond in limited ways to body language and tone of voice by changing their own facial expressions, stance and vocal inflection.

Models

The original Repliee Q1 had a "sister" model, Repliee R1, which is modeled after a 5-year-old Japanese girl.

More advanced models were present at Expo 2005 in Aichi to help direct people to specific locations and events. Four unique visages were given to these robots. The ReplieeQ1-expo was modeled after a presenter for NHK news. To make the face of the Repliee Q2 model, the faces of several young Japanese women were scanned and the images combined into an average composite face. The result is both anonymous and singular.

The newer model Actroid-DER2 made a recent tour of U.S. cities. At NextFest 2006, the robot spoke English and was displayed in a standing position and dressed in a black vinyl bodysuit. A different Actroid-DER2 was also shown in Japan around the same time. This new robot has more realistic features and movements than its predecessor.

In July 2006, another appearance was given to the robot. This model was built to look like its male co-creator, roboticist Hiroshi Ishiguro, and named Geminoid HI-1. Controlled by a motion-capture interface, Geminoid HI-1 can imitate Ishiguro's body and facial movements, and it can reproduce his voice in sync with his motion and posture. Ishiguro hopes to develop the robot's human-like presence to such a degree that he could use it to teach classes remotely, lecturing from home while the Geminoid interacts with his classes at Osaka University.

Commercial applications

According to a poster on the "gallery" section of Kokoro's website[2], Actroid can be rented together with various costumes for use in upmarket coffee shops, bars, information booths, office complexes, and museums or "old houses", in all cases to greet customers and give directions. Kokoro does not publish information about which, if any, corporations have actually rented Actroid for these purposes.

The same poster also suggests the use of Actroid as an ambassador, a spiritual leader, and a nurse. No further details of these applications are provided, although the nursing suggestion is accompanied by a picture of Actroid apparently interviewing a patient. Presumably it cannot yet perform any nursing task except interview, but it is conceivable that even this may be of some value in situations where there are staff shortages and long waiting times, provided the programming is done well. Again, no details are provided of any existing customers, nor are any example conversations provided (the only example conversations shown online are the simple ones from the expo). Rentals currently cost ¥400,000 Japanese ($3,907.48 American as of 2008-04-09) for a 5-day period, plus choreography charges.
