| Abstract: | The tethered-space net robot is one of new technologies for capturing space debris. Rapid deployment and continuous shape maintenance of the tethered-space net robot system are essential in capturing space debris. A single-pulse rotation deployment strategy of the tethered-net robot system is proposed in this paper. The rapid deployment and continuous shape maintenance of the tethered-net are investigated through dimensional analysis, numerical simulation, and regression analysis. Results reveal that the single-pulse rotation deployment strategy can fully deploy the net and maintain the net-shape without any closed-loop controller, and it dramatically increases the effective deployment distance of the net. The parameter sensitivity analyses provide a reference for the rapid deployment and continuous shape maintenance of the tethered-space net robot system. |
