     A group of students in Japan have created an eerily (怪异的) realistic robot baby to motivate young people

to start planning a family and boost the country's birth rate. The automated doll developed at the University of

Tsukuba, called Yotara, giggles (咯咯地笑) and "wakes up" when a rattle is shaken.

     He can become angry and doze off like a real baby and smiles when his stomach is rubbed. The robot can

also sneeze and have a runny nose, thanks to a heated water pump system. The students of the Graduate School

of Comprehensive Human Sciences created the robot with touch sensors. A projector beams ( 照射) the facial

features onto a warm silicon balloon which makes up Yotara's face. The robot's facial expressions and body

movements change according to pressure applied to different parts of its body.

     The information collected through touch sensors under the silicon skin is processed by a special programme.

It then changes the baby's expression projected onto the balloon-face from behind. Its head with a bonnet (童

帽), a colourful blanket covers the robot's limbs which stimulate wiggling with the help of a geared motor. "We

wanted to create a new type of robot that is soft, cuddly and cute," said project leader Hiroki Kunimura.

     "We'd like people to experience the innocent, joyful expressions typical of small babies. Through this

experience, it would be great if some people started feeling that they wanted to have their own baby, if they

started feeling that working is not everything."

     Japan's birth rate is among the lowest in the developed world at 1.37%, compared to 2.12% in the United

States and l.84% in Britain. According to a ministry of labor and welfare report, Japan is facing, serious

economic consequences with over a quarter of its citizens expected to be aged over 65 by 2015. The population

is expected to shrink by a third within 50 years if the birth rate does not increase.
