Dear Sir/Madame
I think robots can do such dangerous jobs as skyscraper builders, bridge builders and so on .If injured or broken, they can be fixed easily. They can also work in unfavorable conditions such as in the dark, extreme heat, extreme  cold, etc.

I suppose robots could be used as chemical researchers. At least they can help us keep away from harmful materials or help to go into small areas which are hard to reach for us. It can be used to examine the inside of a nuclear reactor (核反应堆).
E
Dear Sir/Madame
I suppose robots could be astronauts and they could travel very far away,like Pluto.If so,we don’t need to train human beings to be astronauts as it costs quite a lot and it also takes many years to make a professional astronaut.
