Abstract

Institute of Space and Astronautical Science (ISAS), Japan Aerospace Exploration Agency (JAXA)), Sagamihara, Kanagawa Japan<br />月探査ローバにとって月面上での移動性能は必須の要素技術である.本研究では月の軟弱土壌地盤における走行に特化した移動方式としてスクリュ推進機構に注目している.筆者らはこれまで,スクリュ推進機構の特性および利点に関してまとめ,その有効性を議論してきた.そこで,本稿では特に,スクリュ推進機構を用いたScrew Drive Rover に関して理論的観点からの運動挙動と移動制御に関して新たに検討した結果に関して報告する.<br />For future exploration rovers on the moon, locomotion on lunar surface covered with fine soil, called regolith, is a significant technique. So far, the authors have deliberated a screw propulsion mechanism for traveling on lunar loose soil. Such screw mechanism can be expected to possess a robustness to avoiding getting stuck into the soils. Furthermore, a mobile rover applying two screw units can move in different directions by the simple combination of the screw driving modes without steering. In our research, Screw Drive Rover using the dextral and sinistral screw propulsion units has been proposed ever. So, this paper especially introduces its simplified dynamics model and elaborates its dynamic behavior analytically. The simulation-based analyses of Screw Drive Rover are executed, and its multimodal mobility is confirmed.<br />形態: カラー図版あり<br />Physical characteristics: Original contains color illustrations<br />資料番号: AA0064734024
