A robot cannot think or do things alone. People use a computer to control it. Today, robots are not very popular (phổ biến) because they are too expensive, but they are very useful. They can help us save a lot of time and work. A robot can do the same work for 24 hours, and yet, it does not complain or get tired(mệt mỏi). In the US, people use robots to guard some important places. These robots can listen to certain noises and send signals for help if there's  trouble or danger(rắc rối hoặc nguy hiểm). In Japan, people use robots in factories to build cars. In the future, scientists will design many types of intelligent robots. Their robots will be able to do many more complicated (phức tạp) things. However, some people do not like robots. They fear (sợ) that one day robots will be too powerful(quá mạnh).
