Is Mobile Phones Necessary?
CHAPTER 1 INTRODUCTION
1.1. OVERVIEW: Robots play a vital role in industrial automation, automobile communication, biomedical, weather forecasting and much more areas. Robots are manmade machines to do continuous operation without rest, but the robot’s program comes under flexible automation where new changes cannot be made as per the user. Hence our project is to design a virtual reality Robot which can reproduce human activity. This project is to cater the need of internal and external security to the industries, offices, army and other places where human security is improved. This system eliminates huge losses due to terrorism and antisocial elements. . This project is designed with extreme care for perfect synchronization.

1.2 MEMS: Micro-Electro-Mechanical Systems, or MEMS, is a technology that in its most general form can be defined as miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of micro fabrication. The critical physical dimensions of MEMS devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters.

Likewise, the types of MEMS devices can vary from relatively simple structures having no moving elements, to extremely complex electromechanical systems with multiple moving elements under the control of integrated microelectronics. The one main criterion of MEMS is that there are at least some elements having some sort of mechanical functionality whether or not these elements can move. The term used to define MEMS varies in different parts of the world. In the United States they are predominantly called MEMS; while in some other parts of the world they are called “Microsystems Technology” or “micro machined

    Hitachi Seiki stayed on top of their competitors with a competitive priority producing the best product quality for their customers. To meet this standard Hitachi Seiki set forth a new engineering discipline called Mechatronics, which is the integration of mechanical design and electronics. With this new discipline the company can take action in Flexible Manufacturing Systems (FMS) to be able to meet the needs of their customers and be as flexible as possible to cater to them. The case states, “There were many problems with the new technology, and developments in automation did not materialize as rapidly as expected. As a result, many companies stuck with traditional manufacturing processes.” This set Hitachi Seiki apart from the other companies and they had a competitive advantage among the other companies.…

    Steven Ashley continuous by discussing some of the reasons that why we need mechatronics in our daily life by using different appeals and strategies. What is more, throughout he piece, Ashley uses many strong sources that intensify his credibility call to ethos, as well as build her point of views. Those sources include, “ The basic idea is to apply new controls to extract new levels of performance from a mechanical device,” “Institute for Electrical and Electronics Engineers and ASME,” and the journal which is published by the University of California Berkeley. By citing these sources supports Ashley’s credibility by showing that he has done her research and has shown audiences facts and trues. In his research paper, he also uses his personal examples from his career teaching and study, in which can show that he has a first hand personal experiences base on this topic. In my opinion, he can improve by adding more comparison strategy for the reason that to show how subjects are alike and…

    Mechanical Engineering is the application of the principles of science and mathematics to a design of machinery and equipment used in transportation, manufacturing and energy conversion.The following annotated bibliography contains three sources related to the Mechanical Engineering major. The three sources will include a scholarly journal, a book, and a lab report, with different topics, but all relating to my academic discourse community. The scholarly journal is about a mechanical hand and it covers the basics on how it works without getting too overwhelming. The second source will be a textbook for a general chemistry class, where students are able to learn how to be literate with science. And for third and final source will be a lab report…
