Abstract
In this study, we proposed a new mobility device using tether under the microgravity named Tether Space Mobility Device (TSMD). TSMD is the mobility device that moves user by winding tether which is attached to the structure in the destination. However, this system has problems that TSMD user moves with rotation because the center of gravity of the user deviates from tensile line of action of tether. Therefore, we focused on winding of tether and proposed the attitude control method of TSMD with controlled winding speed. The effectiveness of winding control was inspected by the experiment. The experiment is performed in the two-dimensional microgravity environment. Winding control is that winding speed becomes slow when the acceleration of the experiment equipment exceeded the acceleration threshold. In addition, winding acceleration set small just after the experiment start. In this paper, we producted an experimental equipment that excludes the arm mechanism installed for attitude control. We examined the effectiveness of this system by experiments simulating microgravity using an experimental equipment that was smaller and lighter than conventional equipment.
