Here's my third 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 and 3D Modeled in SolidWorks 2020, this CAD design combines Titanium for a cage structure and Carbon Fiber for paneling the container surfaces. The cage acts as a conveyor with lateral bars to catch and transfer regolith during RASSOR operation. Flexible carbon fiber pieces slip, slide, and bend into position, attaching via bite bolts to the intake of each drum cartridge. Cartridges are independent, bolting together at the hub to form four cartridges. Grain Simulation GIFs in Houdini show grain velocity and adjusted rotation speed to eliminate gravity spatter. Regolith intake is sampled for three full rotations, reflecting the Moon's gravity force with accuracy. This basic simulation demonstrates operational functionality without impacting GIF display on GrabCAD. Used Unreal Engine 4 (UE4) for beauty renders, which escalated into creating GIF animations and a short feature video. The RASSOR Regolith Drum and vehicle were 3D modeled in UE4, then imported to create the environment using Sci-Fi kitbashing props, NASA-provided diffuse textures, and sculpted Moonscape. All animations were done in UE4 Blueprint and Sequencer. Key specifications include: * 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: ~60% The download includes Animated GIFs, Hero renderings, Video Animation, SolidWorks, STEP, and STL 3D files.
