| Summary: | 碩士 === 國立彰化師範大學 === 機電工程學系 === 106 === In recent years, information technology has been developed and realized rapidly to become a killer product in the market, for example intelligent cellular phones, and thus it is going to change human life significantly. In the IT for industry and entertainment applications, augmented reality (AR) is also quickly deployed in the field to play a new role to its applications. Combining the virtual world with the real environment, AR is going to improve the instinctive user experience to their products, systems, and machines. For instance, enhanced assistance in medical operation, instant product experience on the product catalog or educational learning enhance, etc. Otherwise, a low birth rate in many countries such as Taiwan leads a problem of lacking employees in factories. More serious speaking, it may cause the disappear of many valuable engineering experience. To solve this issue, an augmented reality technique may be used to helping young employees fast understand their work content and practice without fault to rapidly improve their professional skills like an expert doing the same task, for example a healthcare and maintenance work.
This goal of this study is to develop a user interface using augmented reality technique associated with a maintenance task of a wafer handling robot arm. First, a 3D graphics of a robot arm including all important components was created using a Computer Aided Design (CAD) tool. Then the AR was implemented with the 3D graphics to provide a step by step procedure regarding the robot dis-and-assembly processes in order to guide a user how to maintain a wafer handling robot by the right way. The AR-based maintenance guideline is able to improve the quality of maintenance where it increases the probability of doing correct maintenance in the first time by a new employee. Besides, AR provides a fast communication interface between an engineer and an expert to decrease the Mean-Time-to-Repair (MTTR). Furthermore, it may decrease the high skill requirement for maintaining equipment. AR also provides a technique to assist the robot to do a maintenance task in the future.
