AB - Space resource development has become a frontier hot topic in international  space exploration. Amidst the growing scarcity of Earth's resources and rare  metals, the harnessing of asteroid resources has risen to prominence as a  principal avenue of exploration. The utilization of asteroid resources  necessitates extensive regolith mining operations. Catering to the demands  of extensive space activities, extra­terrestrial construction, and resource  development, this paper presents the design and simulation analysis of an  extraterrestrial surface regolith composite sampling system. The findings  demonstrate that the composite sampling approach, which combines spiral  drilling and transport with kinetic energy directional excitation, is highly  effective. It is capable of collecting no less than 500 g within a mere 5  seconds at a rotation speed of 3000 rpm, while the reaction force exerted by  the brush remains below 5 N, thus satisfying the requirement for a low  reaction force.
