In the past two decades, personal computers, the World Wide Web, and mobile phones became everyday vocabulary, which shows that the use of these technologies already permeates our lives. Technology has changed the patterns of communication, of work and of leisure.

(111) Robots implemented with artificial intelligence are primarily designed to help people handle a variety of jobs and allow people's lives to be easier.

Technology has improved the quality of human life but also has forced us to handle more jobs and brought pressure into our lives. Some people think a housing robot will help us to do the job that takes lots of time and allow people have more personal time.
