Fahad Azad, an engineer in India, invented a robot named DuctBot．The toy-car sized DuctBot measured 23 centimeters in length, 19 centimeters in width and 9 centimeters in height and weighs just two kilograms．

The robot is designed to snake through dark, narrow air conditioning ducts （管道） and clean them．A pair of LEDs fitted on the robot light up the dirty scenery, so it can be captured （抓拍） by a camera．

In order to control it more easily, Mr. Azad chooses to fix DuctBot on wheels．The robot can clean off lots of dirt, as well as dead pigeons and insects．Keeping indoor air in good quality and monitoring carbon-dioxide levels in buildings with central air conditioning is a challenge．It is important in some places where clean air can mean a difference between life and death, such as hospitals．Dirty air has a bad influence on people's health．

EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad's invention in a national newspaper after he had won an international robotics competition．EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work．Across India, for example, the task still falls to children．They are small enough to go through those ducts．

In 2005, Mr. Azad who was still at university decided to do something about it．Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners．

Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage （污水）pipes．Their biggest challenge is to make the robots user-friendly enough．Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers．There will be lots of difficulties they need to overcome in the future．

On the night of November 14, 1978,a six-year-old Korean boy was flying to the United States. All he knew was that he was on a plane heading for somewhere. The plane landed at Kennedy International Airport, where he was greeted by a family. This young boy was me.

I have grown up in a town where there were few Asians, so I stuck out in the crowd. I made friends quickly and they treated me just like anyone else. You may ask if anyone made fun of my appearance. Well, of course, I met that' kind of person. I just shrugged it off.

As an adopted child, I have something that others don't have. I have had the benefit of two families. I'm lucky to have got a chance to start a new life. But we must try never to forget our past. Someday I will go back to Korea to find out what kind of culture I left behind.

There is only one thing that I regret about being adopted. When I argue with my parents and they realize they are losing the argument, they sometimes wonder what I would be doing if I were back in Korea. I don't understand this because I thought the purpose of adopting someone was to give them a better chance of growing up in a family. Some day when I am older, I want to adopt a girl and raise her the way my parents have raised me, but I would do it better, for I know what went well and what did not.
