Regolith Excavation Performance of a Screw-Propelled

Regolith Excavation Performance of a Screw-Propelled

46th Lunar and Planetary Science Conference (2015 ) 2352

lunar regolith, τ and σ are a function of soil properties including cohesion, internal friction angle, and shear modulus [2]. Traction and motion resistance are func-tions of wheel sinkage. Due to the large area of the screw-terrain interface, which reduces surface pressure, screw-propelled vehicles are characterized by relative-

Regolith excavation performance of a screw-propelled vehicle

Jun 30, 2021 · The optimal configuration yielded a 30 kg/hr excavation rate and 10.2 m/min traverse rate with an overall system mass of 3.4 kg and power draw of less than 30 W. These results indicate that this architecture shows promise as a planetary excavation because it provides significant excavation capability with low mass and power requirements.

Screw-propelled robots could enable mining in space

Oct 06, 2020 · For excavation, a 1-DOF actuator lowers an excavation ramp, allowing material to be collected passively by skimming the ramp against the ground surface using the high-torque counter-rotating mode. The channeled ramp would feed regolith up into the craft body, where the material would then fall into a removable collection bin.
