The Impact of Robots on Human Life

With the development of science and technology, robots play a vital role in human life.
Firstly, robots are more efficient and more time-saving. Robots that can do a variety of work have been invented. They can operate machines in an assembly line,and automatically do housework. The process will need to be set before the robot starts working.

Besides, robots can help to reduce manufacturing costs. Nowadays, it's not an uncommon phenomenon that the population is aging in most of developed countries. Accordingly, the number of workers decreases, and labor cost increases a lot. Manufacturers must be concerned with employment and costs. Luckily，robots can relieve stress in this aspect. Although the cost of robots is high, they can bring a manufacturer profit in the long run.

Finally, some robots are good at doing dangerous work. For instance, cleaning windows on a tall building can be difficult for cleaners, but it is much easier to robots. In addition, robots are the best helper in some circumstances, such as intense radiation, high temperature, poisonous gas etc..
