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, 36 a lot of things in science stories have been science facts. Robots are starting to _37_ in our everyday lives. These robots have different sizes, shapes and colors. But they all have the same _38_ of man-made “_39_”. Leading the robot revolution(革命) are industrial robots that work in factories. Industrial robots can do different kinds of jobs that are often _40_ and sometimes dangerous. Robots are also coming to American homes, though not as quickly asthey are entering _41_. These robots aren’t as friendly and _42_ 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 _43_ objects though they may sometimes drop. Well, nobody is _44_.

We may _45_ home robots today, but some day they may see and hear _46_ than humans do. We _47_

can only see certain wave lengths of light and hear certain _48_. That’s because the _49_ of our eyes and ears are _50_.

Robots, however, need not have the same limits _51_ we have. Robots may also be _52_ wit devices(装置) that  _53_ information humans can’t. However, to understand _54_ their sensing devices pick up is a hard job.

Remember, man-made brains _55_ 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.
