Here’s my second 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 Designed in SolidWorks and simulated in Houdini, this design is a single print body with four divided sections, featuring sawtooth splines for trench cutting, along with helical teeth wrapped on the first 80% of the outside surface to break up and collect regolith efficiently. The four independent sections advance collection and deposition during RASSOR forward and reverse rotations. This design scoops up regolith by initially plunge-cutting into the surface opposite the forward/reverse drive of the RASSOR, then continues rotation while driving forward/reverse to create an excavation trench. The RASSOR can strip that layer and create subsequent layers for continuous regolith collection. Maximum total width of scoops engaged at any given time: 89 mm per drum Maximum bucket drum mass: 5 kg Maximum bucket drum diameter: 450 mm Maximum bucket drum length: 360 mm A minimum volume of regolith captured is 80%. Included in the download are simulation visualized using animated GIFs, a few Hero renderings, and SolidWorks, STEP, and STL 3D files. Thanks for checking it out!
