"The manufacturing industry often uses text and video as a supplement for worker training procedures. Unfortunately, text is often difficult to follow and video lends itself to occlusion issues. CAD based animations of assembly operations can overcome these shortcomings while offering greater potential for operations analysis and simulation flexibility. However, creating such CAD based training simulations manually is a time intensive task and many a times fail to reveal the practical assembly issues faced in the real world. Thus, it is highly beneficial to be able to automate these simulations using motion capture from a physical environment. This thesis research summary includes the development and demonstration of a low-cost versatile motion tracking system and its application for generating CAD based assembly simulations. The motion tracking system is practically attractive because it is inexpensive, wireless, and easily portable. The system development focus herein is on two important aspects. One is generation of model based simulation, and the other is motion capture. Multiple Wii Remotes (Wiimotes) are used to form vision systems to perform 3D motion tracking. All the 6 DOF of a part can be tracked with the help of four Infra-red (IR) LEDs mounted on the part to be tracked. The obtained data is fed in realtime to automatically generate an assembly simulation of object models represented by Siemens NX5 CAD software. A Wiimote Vision System Setup Toolkit has been developed to help users in setting up a new vision system using Wiimotes given the required volume and floor area to be tracked. Implementation examples have been developed with different physical assemblies to demonstrate the capabilities of the system"--Abstract, page iii.
