Household robots have a stylish appearance and a wide range of applications, which are popular among people.They can not only cook and clean the room, but also take care of the elderly and accompany them. In addition, they can also handle emergency situations and make phone calls to save lives.However, the technology used in household robots is not developed well enough to solve all problems. And they are so expensive. Sometimes, they may catch viruses and cause safety problems.
In my opinion, robots should be widely used to improve people's life. Scientists should make robots much more perfect by developing the technology.
