The "forests eyes" and "green guardians".
Protecting green mountains and clear waters.
Because the environment is improving.
Household robots are now widely used in our daily lives.
Household robots, which look modern and fashionable, are very popular with people. We can see many
kinds of household robots.
Household robots have many functions. Firstly, they can be used to cook and clean rooms. Secondly,
they can help to take care of the elderly. Moreover, they can even make calls to deal with something
urgent. For example, they can call 120 when someone needs to go to hospital.
However, the technology used in household robots is not developed well enough to solve all the
problems. Sometimes, they may catch viruses and cause safety problems. In my opinion, robots should be used to improve people's lives. Scientists should make robots help us better by developing the technology. And I think the price is expected to be low enough for common people to afford one.
