Description
Summary:On modern industrial product lines, assembly is predominantly performed through manual labor or using semi-automatic equipment. With the development of automation, robots are becoming crucial in improving the flexibility of production processes. This paper presents an assembly method that employs image processing to control industrial robots in solving a sphere assembly puzzle. By using image-processing techniques—such as block recognition, circle detection, and camera calibration—the system can detect and move randomly placed blocks to the correct assembly positions. Cooperation is also integrated into the system, allowing operators to intervene in the assembly and improving the system’s efficiency while ensuring safety of operators. The results of the application on a practical platform using a HIWIN robot RT605-GB reveal a high rate of successful assembly, providing evidence that the system is effective.
