摘要
Assembly operations in many industries make extensive use of fixtures that are costly and inflexible. The goal of "robotic fixtureless assembly" (RFA) is to replace these fixtures with sensor-guided robots. hi this paper, the development of a vision-guided RFA workcell for automotive components is described. Each robot is equipped with a multiple degree-of-freedom programmable gripper, allowing it to hold a wide range of part shapes without tool changing. A 2D computer vision is used to achieve part pickup which is robust to positioning errors. A novel 3D computer vision system is used to align the parts prior to joining them. The actions of the workcell devices are coordinated using a flexible distributed object-oriented approach. Experimental results are presented for the RFA of four automotive body components.
