英文摘要 | Under the dual influence of China's industrial transformation and upgrading and rising labor costs, labor replacement induced by robots will become an important measure to improve the competitiveness of China's manufacturing industry and provide endogenous power for China's sustained economic growth. Therefore, how to improve the intelligence of robots in the face of complex problems is an important problem to be solved urgently. At present, data-driven technologies and artificial intelligence have shown great potential, which cannot be separated from the support of big data. However, in the field of robotics, the acquisition of big data is not easy, which requires us to turn our attention to virtual space. In recent years, with the rise of the concepts of Industry 4.0, Digital Twins, meta-universe and so on, while people show great enthusiasm for using virtual space, virtual space is also constantly releasing its application potential in the industrial scene. In the factory of the future, traditional control methods are bound to be replaced by real time data driven virtual interaction. However, these methods lack theoretical support and methodological exploration. Based on Parallel systems and ACP (Artificial Societies, Computational Experiments, and Parallel Execution), this paper proposes the framework of Parallel robotics and studies its implementation methods. The parallel calligraphy robot system was developed, and the data-driven methods of the upper and lower levels of tasks were studied around the framework of the parallel robot. The problems of robot calligraphy stroke planning and the optimal tracking control of permanent magnet synchronous motor were solved respectively. The main work of this paper is as follows: 1. Aiming at the problem of insufficient flexibility and accuracy of robot calligraphy, this thesis designs and implements a parallel calligraphy robot system based on the parallel robotics framework based on ACP. The system consists of an execution system, a software-defined system, and an acquisition system. Among them, the execution system consists of a robotic arm and auxiliary equipment to perform the task of writing brushstrokes; the software-defined system consists of robot middleware and simulation algorithms to schedule system resources and simulate the writing process and calligraphy writing results; the acquisition system is composed of a motion capture system, cameras, and auxiliary devices, which are used to collect the process of human calligraphy creation and automatically process the collected data. The operation logic of the parallel calligraphy robot system revolves around the four processes of description, prediction, imitation, and guidance, which realize the closed-loop of robot calligraphy learning and creation in a data-driven manner. Experiments show that the parallel calligraphy robot system can effectively collect, simulate, and execute the process of calligraphy creation. The parallel robotics system proposed in this paper is a multi-domain and interdisciplinary integrated system, including robot hardware and software, sensing, control, machine learning and other contents, with data driven as the core, so that the robot can obtain continuous re-optimization ability. In this paper, the implementation of parallel robot system and the data-driven planning and control method within the framework are preliminarily explored. |
