Whenwe watch movies about the future,
wesometimes see robots. Theyareusually
likehuman servants. They help withthe
houseworkand do jobs like working in dirty
ordangerous places.Todaythere are already robots working in
factories. Some can helptobuild cars, and
they do simple jobs overand over again.Fewer
people will do such jobs in the futurebecause
they are boring, but robots will never get bored.
Scientists are now trying to make robotslook like humans and do the same things as we do. Some robots in Japan can walk anddance.
They are fun to watch. However, some
scientists believe that although we canmake robots move like people, itwill be difficult tomake them really think like a human. For example, scientist James White thinks thatrobots will never be able towake up and know
where they are. But many scientists disagree with Mr. White. They think that robots willeven be able to talk like humans in 25 to 50 years.
Some scientists believe that there willbe more robots in the future. However, they agree it may take(花费) hundreds of years.
These new robots will have many differentshapes. Somewill look like humans, and others mightlook like animals. In India, for example, scientists made robots that
look like snakes. If buildings
fall down with people inside,
these snake robots can help
look for people under the
buildings. This was not possible 20 years ago, but computers androckets also seemed impossible 100 years ago. We never know what will happen inthe future!
