Actroid
Actroid is a type of android (humanoid robot) with strong visual human-likeness developed by Osaka University. 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. 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 gives it the ability to react in a different way to more gentle kinds of touch, such as a pat on the arm.
