Design and Validation of In-Situ Unmanned Autonomous Lunar Rock Grinding Powder Preparation Device

As lunar exploration programs advance, in-situ prospecting and utilization of extraterrestrial resources have emerged as a strategic priority for the next phase. These regions harbor critical rock samples key to deciphering lunar evolution history, yet their extreme environments pose severe challenges for in-situ collection and processing. This study proposes a novel in-situ unmanned autonomous lunar rock grinding powder preparation device through highefficiency clamping-grinding, and high-fidelity surface profiling. The system features: A flip-clamping end-face grinding mechanism that adaptive stabilised gripping irregular rocks Ø 15-45 mm) and prepares micron-level powdered samples with powder sample induced collection; A scraping-compression composite board that generates highflatness analytical surfaces and delivers samples to analysis stations. This technology demonstrates robust adaptability to extreme lunar conditions at low resource cost, providing critical capabilities for future lunar resource prospecting and utilization.
