Abstract:Excavation of regolith is the enabling process for many of the in situ resource utilization (ISRU) efforts that are being considered to aid in the human exploration of the moon and Mars. Most proposed planetary excavation systems are integrated with a wheeled vehicle, but none yet have used a screw‐propelled vehicle which can significantly enhance the excavation performance. Therefore, CASPER, a novel screw‐propelled excavation rover, is developed and analyzed to determine its effectiveness as a planetary exca… Show more
