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.

gives it the ability to react in a different way to more gentle kinds of touch, such as a pat on the arm. 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. 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.

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.

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 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. In May 2011 a Danish professor, Henrik Schärfe, revealed a robotic version of himself. Manufactured in Japan and called a Geminoid-DK, its actions are controlled remotely by a person operating a computer, but it is programmed with Schärfe's own unique body movements, such as shrugs and glances.
