大型复杂构件多机器人移动加工的自律跟踪与协同控制

This project is inspired by the challenge of the efficient and adaptive machining for large-scale components. By integrating mobile robotics, digital manufacturing technology and artificial intelligence technology，this project aims at constructing new principle and new equipment for adaptive machining through mobile manipulators. The project focuses on the research of compliant actuator, dual-robot cooperative control and efficient in-situ accurate measurement, including: (1) Design and control of end effector with force-position double closed-loop in mobile machining system; (2) Multi-robot cooperative motion planning and control under complex constraints; (3) Local in-situ precise measurement and efficient global reconstruction of large-scale complex components; (4) R&D and experimental verification of the robot mobile machining system prototype . On the basis of these research, an autonomic tracking and cooperative control theory for multi-robot mobile machining for large-scale complex components is expected to be established; The active compliance of the robot equipment to the parts will be realized by the force-position hybrid control of the active compliant actuator; Through the dual robot coordination control and efficient in situ measurement technology, it is expected to realize efficient adaptive machining of the large complex component with low-rigidity structure. The outcome of this project will significantly promote the national level in automation and intelligent manufacturing of large-scale complex components, and will facilitate the technology development of robotized intelligent manufacturing equipment.
