Intelli-Wrench: Smart Navigation Tool for Mechanical Assembly and Maintenance

We present Intelli-Wrench, a smart tool for providing just-in-time information for mechanical assembly and maintenance workers, which releases the workers from miss-operation and annoying manual documents. The Intelli-Wrench captures the image of a bolt head as its "fingerprint" by using FIBAR (Fingerprint Imaging by Binary Angular Reflection) imaging method. The fingerprint image is then uploaded to a cloud server and matched with parts databases in order to provide the specific information associated with the bolt. Receiving the information, the Intelli-Wrench informs the workers about the designated location and torque requirements of the bolt. This direct integration of information retrieval into a tangible tool provides immediate access to relevant information otherwise found in manual documents. Furthermore, the Intelli-Wrench automatically logs the interaction and eliminates the annoying pointing-and-calling procedure which is the traditional way of secure servicing. We demonstrate a working prototype and interaction scenario.
