About this technology
Overview
RUM combines the function of multiple tools into one package that is ideal for smaller scale planetary ISRU and construction technology . The system was devised as a way to perform the collection of regolith feedstock, size screen it, convey to ISRU plant or other system, and perform site preparation/regolith manipulation tasks, and perform in-situ geotechnical measurements all with a single robotic arm's end effector tool. This was designed to reduce flight mass compared to splitting these capabilities across multiple tools that might be installed onto a lander or multiple arms. For a large set of in-situ based site-preparation and construction tasks on the lunar surface, there is a need for size-sorted/screened regolith media. The capability to provide these functions while minimizing mass and volume is very beneficial. Structures such as flat, rock free, operational areas as well as berms, roadways, landing pads, and trenches are critical first-step infrastructure on the lunar surface and technology demonstration missions that prove the capability to build these structures are imminent as part of the Artemis Program and future lunar base construction.
