引言 从本世纪四十年代末,低成本自动化已被广泛用于工厂的自动化装置方面。自动化实现大量生产,使工业产品成本不断降低,作用十分重要。从广义上讲,自动装置不仅包括气动和电子气动部分,而且还包括有机械、液压、电气、电子等部分,甚至数字控制。 Introduction Low-cost automation has been widely used in factory automation devices since the late 1940s. Automation to achieve mass production, the continuous reduction of industrial product costs, the role is very important. Broadly speaking, robotic devices include not only pneumatic and electronic pneumatic components, but also mechanical, hydraulic, electrical, electronic, and even digital controls.
