5、多数的机器人用于汽车工业，此外在别的工业领域虽然应用的程度低一些，（although to a lesser degree）但也开始出现。它们已经可以代替人进行一些工作。那么机器人与自动化机械有什么不同呢？它们的不同在于机器人完成某一特定任务后，可由计算机重新编制程序去完成另一项任务。现在科学家与工程技术人员正在研制新一代机器人，使机器人具有视觉、有触觉、并且能够做出关键性的决策。未来机器人将会在许多领域代替人的工作。Paras.1-3 Robots are used in many areasPara.4 The difference between robots and other mac
