And What’s Next? Mechatronics, the term coined in Japan in the 1970s, has evolved over the past 25 years and has led to a special breed of intelligent products What is mechatronics? It is... part of the twentieth century Standing at the threshold of the twenty-first century, with expected advances in integrated bioelectro-mechanical systems, quantum computers, nano- and pico-systems, and other unforeseen developments, the future of mechatronics is full of potential and bright possibilities 1.1 Basic Definitions The definition of mechatronics has evolved since the original definition by the Yasakawa... entirely mechanical in nature and the automation and control systems were implemented only as an afterthought The launch of Sputnik and the advent of the space age provided yet another impetus to the continued development of controlled mechanical systems Missiles and space probes necessitated the development of complex, highly accurate control systems Furthermore, the need to minimize satellite mass (that . sheet-fed process wherein the paperboard is cut into a fan shape to form the tapered sidewall, and wrapped around a mandrel.
