Web-Based Remote Manipulation of Parallel Robot in Advanced Manufacturing Systems

摘要

During the last decade, the Web has gained widespread acceptance in both academic and business areas. The Web is used by many as a medium of sharing data, information, and knowledge. Today, it is widely used for development of collaborative applications to support dispersed working groups and organizations because of its platform, network and operating system transparency, and its easy-to-use user interface – Web browser. In addition to the Web technology, Java has brought about a fundamental change in the way that applications are designed and deployed. Java’s “write once, run anywhere” model has reduced the complexity and cost traditionally associated with producing software on multiple distinct hardware platforms. With Java, the browser paradigm has emerged as a compelling way to produce applications for collaboration over the Internet. As business grows increasingly diversified, the potential of this application is huge. Targeting distributed, real-time monitoring and control in manufacturing sectors, a framework with high efficiency for cyber collaboration is carefully examined. The objective of this research is to develop a Web-based digital shop floor framework called Wise-ShopFloor (Web-based integrated sensor-driven eShopFloor) for distant shop floor monitoring and control. The Wise-ShopFloor, with an appropriate architecture for effective data communication among a dispersed engineering team, can serve real-time data from bottom up and can function as a constituent component of e-manufacturing. The framework is designed to use the popular client-server architecture and VCM (view-controlmodel) design pattern with secured session control. The proposed solutions for meeting both the user requirements demanding rich data sharing and the real-time constraints are: (1) using interactive Java 3D models instead of bandwidth-consuming camera images for visualization; (2) transmitting only the sensor data and control commands between models and device controllers for monitoring and control; (3) providing users with thin-client graphical interface for navigation; and (4) deploying control logic in an application server.
