| Outline of Final Research Achievements |
In this reserch, we discuss the motion of a tethered system during winding a tether in microgravity. When the tether is being wound, it comes into strong contact with the feeding section of the system. Accordingly, both are expected to undergo complex motion as they interact with each other. We have therefore carried out both a numerical and an experimental study to clarify the motion of such a system using a mobility device using the tether named TSMD proposed by us as an example. Furthermore, we proposed a TSMD attitude control method during tether winding while focusing on changes in the system's rotational kinetic energy. Using the proposed analytical model, the angular velocity of a rigid body system is confirmed to converge to 0 deg/s when control is applied.
