嬰兒機(jī)器人會(huì)哭笑 讓人體驗(yàn)育兒樂趣

It giggles and wiggles its feet when you shake its rattle, but will get cranky and cry from too much tickling: Meet Yotaro, a Japanese robot programmed to be as fickle as a real baby.

The cuddly baby-bot looks unearthly with a pair of luminous blue eyes and oversized cheeks, but engineering students are hoping it will teach young people the pleasures of parenting as Japan faces a demographic crisis.

"Yotaro is a robot with which you can experience physical contact just like with a real baby and reproduce the same feelings," said Hiroki Kunimura of Tsukuba University's robotics and behavioral sciences lab north of Tokyo.

Yotaro's face, made of soft translucent silicon with a rosy hue, is backlit by a projector connected to a computer to simulate crying, sneezing, sleeping and smiling, while a speaker can let out bursts of baby giggles.

The baby changes its facial expressions and moves its arms and legs when different parts of its face and body are touched. Physical contact is detected by sensors, and Yotaro's mood changes based on the frequency of touches.

Yotaro also simulates a runny nose, with the help of a water pump that releases body-temperature droplets of water through the nostrils.

While the baby robot has a balloon-sized head and exaggerated facial features, its inventors nonetheless hope "Yotaro could help young parents to learn about raising a baby," said research team member Masatada Muramoto.

"We came up with the idea of a baby robot because we wanted to reproduce a human being's warmth and skin colour," said Kunimura.

"We decided on an infant that has not yet learnt to talk because the feelings generated towards a newborn will be the same for everyone, and because interaction is less complicated than if we had made it talk."

Japan is already famous for highly sophisticated robots, from Honda's humanoid Asimo to pancake-flipping chef Motoman to Paro the fluffy robot seal that helps ease loneliness among the elderly.

Hundreds of thousands of industrial robots toil in factories, while robo-receptionists can serve tea, greet guests or vacuum corridors.

當(dāng)你搖動(dòng)它身體上的撥浪鼓時(shí)，它會(huì)扭動(dòng)小腳丫，發(fā)出咯咯的笑聲，但如果不停地?fù)纤W癢，它就會(huì)發(fā)脾氣哭鬧——這就是“陽太郎”，日本發(fā)明的一款會(huì)像真正的嬰兒那樣喜怒無常的機(jī)器人。

這個(gè)機(jī)器人嬰兒的外表與眾不同，它有著超大的臉頰和一雙藍(lán)色發(fā)亮的眼睛，看上去十分討人喜愛。研究人員希望在日本面臨人口危機(jī)的大背景下，這款機(jī)器人能讓年輕人體驗(yàn)到育兒的樂趣。

位于東京北部的筑波大學(xué)機(jī)器人技術(shù)和行為科學(xué)實(shí)驗(yàn)室的國(guó)村廣城說：“陽太郎可以讓你體驗(yàn)到與真正嬰兒進(jìn)行身體接觸的感覺，這種感覺是一樣的。”

陽太郎的臉部由柔軟半透明的玫瑰色硅膠制成。它的臉部下面有一個(gè)投影設(shè)備打出背光，這個(gè)設(shè)備與電腦相聯(lián)，在電腦的控制下，陽太郎會(huì)做出哭泣、打噴嚏、睡覺和微笑等動(dòng)作和表情，同時(shí)還有一個(gè)揚(yáng)聲器可以發(fā)出陣陣咯咯的嬰兒笑聲。

當(dāng)觸摸“陽太郎”臉部和身體的不同部位時(shí)，它的面部表情會(huì)發(fā)生變化，還會(huì)移動(dòng)胳膊和雙腿。陽太郎通過傳感器感受人的“愛撫”，根據(jù)觸摸頻率的不同，陽太郎的“情緒”也會(huì)隨之變化。

陽太郎還會(huì)流鼻涕，這一功能主要通過一個(gè)水泵來實(shí)現(xiàn)。在水泵的幫助下，與體溫溫度差不多的水滴就會(huì)從陽太郎的鼻孔中流出。

這個(gè)機(jī)器人嬰兒的頭和氣球差不多大小，面部特征也比較夸張，但研究小組成員村本正忠說，它的發(fā)明者希望“它能夠幫助年輕夫婦學(xué)會(huì)如何育兒。”

國(guó)村說：“制造這款機(jī)器人源于我們想仿制人類體溫和膚色的想法。”

“我們決定制造一款不會(huì)說話的嬰兒機(jī)器人，因?yàn)榇蠹覍?duì)新生兒的感覺都差不多，而且相對(duì)于會(huì)說話的機(jī)器人，與不會(huì)說話的機(jī)器人交流起來也簡(jiǎn)單一些。”

日本素以制造高端精密機(jī)器人而著稱，從本田公司的仿人機(jī)器人阿西莫到會(huì)拋煎餅的廚師機(jī)器人莫托曼再到幫助老年人排解寂寞的毛茸機(jī)器海豹帕羅，五花八門，無所不有。

另外還有能奉茶、迎賓、會(huì)用吸塵器的機(jī)器人接待員，以及數(shù)十萬在工廠里勞作的工業(yè)機(jī)器人。
