In this study, the authors model and conduct experiment on the braid propulsion unit of an excavation robot for lunar exploration. In existing studies, it is difficult for robots to create sufficiently big holes and achieve deep excavations. Therefore, in this study, we developed a lunar earthworm-type excavation robot “LEAVO,” which attempts to excavate boreholes for environmental sensors and collect samples in particular layers. LEAVO has already succeeded in a vertical excavation of more than 938 mm and we have verified its usefulness in the first target mission. However, the existing propulsion unit of LEAVO cannot sufficiently bend and grip curved or uneven walls. In this research, we proposed a novel propulsion unit using braid to achieve curving excavation for the second target mission, modeled the gripping force of the proposed mechanism, and measured the gripping force of the prototype using the mechanism. The experiment demonstrated the validity of the modeling and the usefulness of the proposed mechanism.
