Roby Mini is just 40 centimeters tall, has a large round screen for a head and has been designed to help senior citizens living alone.

Manufactured by robotics pany Shanghai PT Info, the brightly colored robot, which costs 5,000 yuan ($790), was launched on Aug 14 to help entertain and monitor elderly people.

In Shanghai last year, the number of registered residents at least 60 years old was 4 million. That was nearly 30 percent of the population. By 2021, the figure is projected to rise to 5 million.

With many living alone, robots such as Roby Mini can help play a crucial role in caring for the elderly. "It will change the way people interact with digital products," Hong says.

Founded in May, Shanghai PT Info had already done the groundwork. In fact, the research team spent three years developing the speech recognition system before the firm was officially launched.

With 360-degree wheels hidden under its body, Roby Mini can follow a person through face recognition and strike up a conversation, tell jokes or provide information.

The robot also works as a puter terminal, supplying weather information, ordering groceries online and even booking taxis. Roby Mini can be connected to other gadgets as well, such as smart wristbands or magnetic devices on doors.

Roby Mini can also connect an elderly owner to a doctor through its high-definition screen.Already Shanghai PT Info is talking to three munity hospitals in Shanghai's Minhang district. Since the robot is linked to the Internet, it can support long-distance audio and video calls.

Mass production started this month and Shanghai PT Info plans to manufacture 200,000 units this year.

But the future is not easy for Shanghai PT Info. Earlier this year, Flyingwings Intelligent Robot Technology (Shanghai) introduced a machine with sensors that will ring an alarm when an elderly person falls down.Tianjin ShangjiuShengyuan Technology Group also developed a robot for seniors in 2014. Owners can turn on the lights and air-conditioning units by pressing buttons on the machine.It can also remind elderly owners to take pills, and inform them of hospital checkups and family birthdays.

（课外选材）

When puter servers operate a plex program, they can get very hot. Cooling the servers can be costly. So researchers asked what would happen if the heat created by the servers could be captured and used?

Data centers of large Internet panies such as Google and Microsoft have thousands of puter servers. As these servers process information, they create large amounts of heat, so they need huge cooling systems. These systems send the heat into the air. The Dutch pany Nerdalize thinks paying for electricity to operate the servers and then paying again to cool them is a waste of energy. So it developed a device called the e-Radiator. It is a puter server that also works as a heating source. Boaz Leupe is the chief executive officer of Nerdalize. He says the e-Radiator saves money because panies don't have to pay to cool their servers.

"The kilowatt（千瓦）hour you are using is used twice -- once to heat the home and once to pute the client's task without the cooling overhead." He says five homeowners in the Netherlands are testing the heating device in their homes. "We reimburse the electricity the server uses, and that we can do because of the puter clients on the other side, and, in that way, homeowners actually get heating for free, and puter users don't have to pay for the overhead of the data center."

Jan Visser is one of the participants in the year-long experiment. He says the amount of heat produced by the e-Radiator depends on the work being done by the puter server. He says it cannot be used as the primary source of heat. But he is ready to try it.

He says if it provides enough warmth, he will be able to use his home's heating system less, which will save him money. Nerdalize says e-Radiators create heat temperatures of up to 55℃. It says the devices could save users up to $440 in heating costs a year.

?

Why did researchers ask what would happen if the heat created by the servers could be captured and used? 1

A. Because puters can get very hot.

B. Computer servers is a plex program.

C. Cooling puter servers costs a lot of money.

2.The puter servers in large Internet panies such as Google and Microsoft can 2 .

A. create large amounts of information

B. create large quantity of heat

C. manage the huge cooling systems

3. Nerdalize developed the e-Radiator because 3 .

A. e-Radiator cost less energy

B. e-Radiator can cool the servers for free

C. e-Radiator can create cold air for free

4.According to Jan Visser, the amount of heat produced by the e-Radiator 4 .

A. depends on the work being processed by PC

B. cannot be used as the home's heating system

C. cannot be used as the main source of heat

5.The best title for this passage is 5

A. The New Way to Heat Homes

B. The New Way to Cool Homes

C. Hot Computers Could Be Used for Free
