Cars, undoubtedly, are one of the most important transportation tools today. They have had a huge influence on our daily lives. In my opinion, when it comes to the future of the automobile industry, there are three challenges: accidents, traffic jams and pollution.

The first two challenges can be solved by artificial intelligence (AI) and the Internet of Things. These two technologies will make self-driving cars a reality. Cars will drive themselves to their destinations automatically. Thanks to the IT, cars, traffic lights and even pedestrians will be connected with each other. Traffic information will be transmitted in real time. For example, if there is roadwork ahead, the AI system will tell the car to change its planned route. This way, traffic jams can be avoided. There will also be fewer accidents caused by careless drivers.

The last challenge, pollution, can be solved by exploring new sources of energy. Electric cars are much cleaner than petrol cars. In recent years, electric cars have already become more and more popular. Many people have been driving electric cars. However, new problems, such as pollution caused by old batteries, have been arising. How can we solve these problems? It’s high time we thought about that.

There is still a long way for us to go. I believe that with our combined efforts, newer and more reliable technologies will appear. They will help create a brighter future for road transportation.

Nexi is one of a new generation of robots. It moves on wheels and can pick up objects. But robots like Nexi are more than just entertaining toys.

Nexi, a social robot created by scientists at the Massachusetts Institute of Technology(MIT), can express human emotions. Roboticists at MIT call Nexi a “social robot”. A social robot is a robot that can communicate like a human. Nexi can look sad, mad, and even bored. Some social robots can also “read” our facial expressions. Roboticists believe that it won’t be long before we have social robots in our homes, helping us live better lives.

Autom is another social robot developed at MIT. Autom is a robot health coach. It has a screen where you enter information about what food you eat that day or how much you exercised. Autom has a face with eyes that move. It speaks with a synthesized（合成的）voice. Autom gives you advice about your diet and exercise and drives you to do better.

In a test, Autom helped people lose weight better than other ways of recording diet information. Roboticists think this is because Autom used facial expressions and words of encouragement. In other words, Autom communicated like a real person. In fact, many people who used Autom gave the robot a new name and talked to it. When robots use human expressions and body languages, people reply to them a lot like they reply to people.

In the future, humans may communicate with social robots just like they do with other people. Let’s wait and see what will happen in the future!
