Unit 2 RobotsAbout robotsA robot is a machine which is designed to do the work of a human being. It is usually controlled by a computer. Once it has been given a set of things to do, it will do the job on its own. Robots can paint cars, salvage (抢救) nuclear fuel and even assist in brain surgery (外科手术), but they're still pretty dumb. Today robots can recognize forms and shapes and measure distance and so on. Many robots have one or two of these abilities to some degree, but creating a competent ( 有 能 力 的 ) robot that combines most or all of them has been difficult.Current ( 目 前 的 ) robots have advanced sensory systems that process information and appear to function as if they had brains. Their “brain” is actually a form of computerized artificial intelligence (Al). Al allows a robot to perceive conditions and decide upon a course of action based on those conditions.A robot can include any of the following parts：effectors — “arms”“legs”“hands”“feet”sensors — parts that act like senses and can detect ( 侦 测 ) objects or things like heat and light and change the object information into symbols that computers understandcomputer — the brain that contains instructions called algorithms (规则系统) to control the robotequipment — this includes tools and mechanical fixtures (机械手臂)开启快乐学习之旅未来的机器人会是什么样子，现在的机器人由哪些部分构成，它们主要应用在哪些领域？阅读本文，了解机器人的一些基本常识吧！Unit 2 Robots Section Ⅰ Warming Up ReadingⅠ.重点单词1．desire vi. 渴望；欲望；渴求；vt. 希望得到；想要2．satisfaction n. 满意；满足；令人满意的事物satisfy vt. 使满意；使满足satisfied adj. 感到满意的；感到满足的3．alarm vt. 使警觉；使惊恐；惊动；n. 警报；惊恐alarmed adj. 担心的；害怕的4．sympathy...
