Robots seem new to some people, but they have a long history. 【小题1】 From then on, all kinds of different robots came to people lives. 【小题2】 The robots in these movies are faster, smarter and stronger than people.

【小题3】 Robots are often used to do dangerous and boring jobs in factories. In people’s homes, robots can help clean the windows and the floor. They can take meals from the kitchen to the sick people’s rooms in hospitals. 【小题4】 Some people can’t move, so many of them use a robot to help them get better. Finally, they could walk around like a normal man.

People will improve robots with the development (发展) of science in the future. 【小题5】 So that they can help us in a lot of different ways.

A student project has showed another power of AI: It can be good at locating (确定……的准确位置) where photos are taken.

The project is called Predicting Image Geolocations(or PIGEON). It’s the work of three Stanford students. They made it in order to identify (确认) locations.

The team also showed the AI a few personal photos it had never seen before. To their surprise, the program was, in most cases, able to tell where the photos were taken.

PIGEON works well because it can pick up all the little things in photos. It can notice small differences in leaves, soil and weather. The group says the technology can be used in many ways. It could check roads that need fixing. It may also help researchers do surveys of the environment.

However, this new power is likely to cause some risks. It could be used to get personal information, says Jay Stanley, an expert. Stanley worries that companies might soon use AI to find out where you’ve traveled. Governments might check your photos to see if you’ve visited certain countries. The Stanford students know the risks well. Because of these worries, they don’t allow the public to use their program.

Stanley thinks the use of AI for identifying locations will become even more powerful in the future. What will that mean? Well, be very careful about what’s in the background in the photos you post online! Though AI seems much smarter, it can still be made good use of as long as we are wise enough. After all, we humans can learn and think by ourselves.

Programming Pain

Robots are useful and taking place of humans in some areas because they never get tired and can't feel pain. However, some researchers believe it's a good idea to program robots to feel pain.

Researchers from Leibniz University of Hannover in Germany are working to develop an artificial（人造的）robot nervous system to teach robots how to feel pain. "Pain is a system that protects us," said Johannes Kuehn, one of the researchers. "When we try to avoid the pain, it helps us not get hurt.”

Think about how many injuries you would receive if you couldn't feel pain. Even though pain hurts, it helps us avoid danger and treat our wounds. The same will be true for robots. As a great number of people work closely with robots, the robots must behave in a safer manner. Kuehn believes that by protecting robots from damage（伤害），they'll be protecting people as well. Damage,to robots if left unseen could lead to workplace accidents.

Rather than feel pain, some robots are designed to show pain or see it in others. Asada, an engineer at Osaka University in Japan, and his workmates have made sensors （传感器）that pick up many types of touch signals（信号）.These touch and pain signals can turn into emotions and expressions on a robot’s face. Asada believes that these systems could finally lead to robots seeing the pain on human faces, an important skill for robots designed to care for elderly people, for example.

Antonio Damasio, a professor at the University of Southern California, argues that programming robots with a sense of pain may cause an artificial sense of feeling to develop. But he says that this communication is not the same thing as a robot truly feeling and expressing emotions or pain. If one day, robots could actually feel as humans do, Damasio has a suggestion for the number one rule for robots: Feel good.
