高中英语Unit3 Computers文章 什么是机器人人教版必修二
.

什么是机器人
美国是机器人的诞生地,早在1962年就研制出世界上第一台工业机器人,
比起号称"机器人王国"的日本起步至少要早五六年。
经过30多年的发展,美国现已成为世界上的机器人强国之一,基础雄厚,技术先进。
讲到什么是机器人时,我们大多数人都看到过电影或书本里描绘的外形酷似人类的机器人,这是机器人的一种表现形式。
可机器人并不一定非得是这样的。
事实上,机器人的形状各式各样。
我们身边到处都有机器人。
机器人能够代替人类完成重复乏味或者危险的工作,提高我们的生活品质和工作效率。
机器人技术综合机械工程、电子工程、传感器应用、信息技术、数学、物理等多学科知识,代表着一个国家的高科技发展水平。
实际意义上的机器人,应该是“能自动工作的机器〞有的功能很简单,有的就复杂得多。
例如:家里的供暖系统,我们只需做最初设定接下来它就能自己工作,我们身边的大多数家用电器都是这样。
自动温控系统的元器件遍布于整座智能化大楼。
