The Automated Threaded Fastening Based on On-line Identification
International Journal of Advanced Robotic Systems, 2004 The principle of the thread fastenings have been known and used for decades with the purpose of joining one component to another. Threaded fastenings are popular because they permit easy disassembly for maintenance, repair, relocation and recycling ...
