The ultra-lifelike robot Repliee Q1 made quite an impression at the 2005 World Expo in Japan. Shown below (at left!) with co-creator Hiroshi Ishiguru, the robot is so lifelike that roboticists may want to start working on a Bladerunner-style Voight-Kampff test now.

Repliee Q1 has silicone for skin, rather than hard plastic. It has a number of sensors to allow it to react in a manner that appears natural; it appears to flutter its eyelids, chest movements correspond to breathing, and other tiny shifts in position that mimic unconscious human movement.The android can mimic actions made by a human; this helps the robot's movements appear more lifelike. By facing a person with reflective dots placed at key points (like wrist, elbow, palm), the robot can try to match those points on its own body with those of the person who is "modeling" human movement.
The greatest limit to the lifelike movement of the robot is that it has only 31 actuators in its upper body; a nearby air compressor provides the energy needed for articulation.
In his excellent novel Do Androids Dream of Electric Sheep, Philip K. Dick explores what happens in a society when android replica humans cannot be physically distinguished from human beings. Only the Voight-Kampff empathy test can make the distinction, when used by a trained officer like Rick Deckard:
San Francisco's Wave magazine recently wondered whether or not candidates for their mayoral elections were humans or androids; they applied an empathy test to make sure. See Is Your Candidate Human?.
