机器人能够越来越多地代替人类从事某些艰难、危险,甚至较为复杂的劳动,关键在于有能指挥、控制其行为的“电脑”,以及能感知外界环境变化并作出反应的“电五官”——“电子眼”(视觉器官)、“电子耳”(听觉器官)、“电子鼻”(嗅觉器官)、“电子舌”(味觉器官)和“电子手”(触觉器官)。由于微电子技术、自动控制技术、传感技术的发展和进步,“电五官”的灵敏度越来越高,在信息科学技术中获得了日益广泛的应 The crux of robots being able to replace more and more human beings with some difficult, dangerous and even complicated tasks lies in the “computers” capable of directing and controlling their behavior as well as the “electric facial features” that can sense and respond to changes in the external environment. - “electronic eye” (visual organ), “electronic ear” (auditory organ), “electronic nose” (olfactory organ), “electronic tongue” (taste organ) and “electronic hand” (tactile organ). Due to the development and progress of micro-electronic technology, automatic control technology and sensor technology, the sensitivity of “electric five-officer” is getting higher and higher, and it has been widely used in information science and technology
