原文摘要 · Abstract (English)

The integration of robotic arm manipulators into industrial manufacturing lines has become common, thanks to their efficiency and effectiveness in executing specific tasks. With advancements in camera technology, visual sensors and perception systems have been incorporated to address more complex operations. This study introduces a novel visual serving control system designed for robotic operations in challenging environments, where accurate object pose estimation is hindered by factors such as vibrations, tool path deviations, and machining marks. To overcome these obstacles, our solution focuses on enhancing the accuracy of picking and placing tasks, ensuring reliable performance across various scenarios. This is accomplished by a novel visual servoing method based on the integration of two complementary methodologies: a technique for object localization and a separate approach for precise control through visual feedback, leveraging their strengths to address the challenges posed by the industrial context and thereby improving overall grasping accuracy. Our method employ feedback from perception sensors to adjust the control loop efficiently, enabling the robotic system to adeptly pick and place objects. We have introduced a controller capable of seamlessly managing the detection and manipulation of various shapes and types of objects within an industrial context, addressing numerous challenges that arise in such environments.
