NASA Regolith Drum E1

Here’s my entry for the “NASA Regolith Advanced Surface Systems Operations Robot (RASSOR) Bucket Drum Design Challenge” found here: https://grabcad.com/challenges/nasa-regolith-advanced-surface-systems-operations-robot-rassor-bucket-drum-design-challenge I designed a single solid titanium print body with no assembly, featuring exterior and interior features to dig, pulverize, grade, and contain regolith during gathering and depositing. Four section traps are included, each containing three scoops for a total of twelve scoops per drum; a four-drum configuration would have mirrored parts and features. This design takes step-cuts into the regolith in a left-to-right series that forces regolith into containment or pushes excess debris outward from the RASSOR vehicle. Larger debris is kicked forward and clear of the current dig path. Maximum total width of scoops engaged at any given time: 88 mm per drum Maximum bucket drum mass: 4.73 kg Maximum bucket drum diameter: 450 mm Maximum bucket drum length: 360 mm A minimum volume of regolith captured remains to be determined. The design includes simulation visualized using animated GIFs, Hero renderings, a quick drawing, SolidWorks files, STEP files, and STL 3D files.
