I agree with the idea that in the future robots will be very useful to us. Firstly, robots can be made of non-biological materials, rendering them able to withstand environments too toxic, too high or low temperatures, or having other conditions unsuitable for human workers. Secondly, robots do not need to be fed "food" in the traditional sense. They can operate using electricity from a variety of sources. In space, such electricity can come from the sun via solar cells or from fuel carried on board used to make electricity. Thirdly, robots do not get tired, and they can work long hours in dangerous locations that would wear out most astronauts. Fourthly, robots can be equipped with sensors and tools that are more sophisated than the human eyes or ears or hands, rendering robots capable of highly complex tasks. Lastly, robots do not age over time. For long interstellar journeys, they can be placed in a dormant state, to be waken up months or years later ready to go to work. For these reasons and others, robots are ideal machines for use in building space stations on many planets.
