英文摘要: For the capture system of uncontrolled satellites and clean-up tasks of space debris in future, space robots will be widely used because of its advantages in the space operation service such as flexible operation, safety, and so on. This project proposes a concept of tethered-net space robot system, which will be advantage to the traditional space robots with rigid manipulator especially in capturing of non-coorperation satellites such as uncontrolled satellites and space debris. The research of tethered-net space robot system is still in its infancy, and especially the research of space flexible combination of tether and net is almost empty. But its prospects for future applications has been widely recognized. Therefore, it has important technology value to study the key technologies of tethered-net robot system. The main key technolgoies of the project are to be include: modelling of flexible combination of tethered-net space robot system, the coupling dynamics analysis among platform satellite, and tether-net, the dynamics and coordinated control of dynamical release of the tether-net, contact-impact studies of rigid (target satellite) - flexible (net). To resolved these key technologies will promote the application and development of the space tethered-net robot.
