Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such as Star Wars. Today, 1a lot of things in science stories have been science facts. Robots are starting to _2_ in our everyday lives. These robots have different sizes, shapes and colors. But they all have the same _3_ of man-made “_4_”. Leading the robot revolution(革命) are industrial robots that work in factories. Industrial robots can do different kinds of jobs that are often _5_ and sometimes dangerous. Robots are also coming to American homes, though not as quickly asthey are entering _6_. These robots aren’t as friendly and _7_ as those you saw in Star Wars. But, their makers say, today’s home robots “walk” and sense objects in their own way. They even _8_ objects though they may sometimes drop. Well, nobody is _9_.
We may _10_ home robots today, but some day they may see and hear _11_ than humans do. We _12_
can only see certain wave lengths of light and hear certain _13_. That’s because the _14_ of our eyes and ears are _15_.
Robots, however, need not have the same limits _16_ we have. Robots may also be _17_ wit devices(装置) that _18_ information humans can’t. However, to understand _19_ their sensing devices pick up is a hard job.
Remember, man-made brains _20_ information, including all kinds of data, as zeroes and ones.
Imagine the difficulty in trying to explain to a robot what a football looks like---using only zeroes and ones.
