ZigZag Design For RASSOR Bucket Drum

grabcad

In this design, I employed the zigzag model for engaged blades with the moon regolith. This approach ensures full sampling, with no regolith samples left behind because the bales fully cover each other. If blades are broken, they can be easily replaced since they attach to the bucket drum with 4 steel screws made from aluminum 5356 alloy. Alternatively, these screws can also be crafted from the same aluminum 1100 alloy used in our satellite structure. The blades themselves are fabricated from brass to prevent deformation, contraction, and expansion due to the low temperatures of the lunar atmosphere and other unwanted factors. Additionally, the blades have undergone FEA analysis to ensure their structural integrity. All parts can be created using multi-axis CNC milling machines or 3D printing technology. The total mass of this design is 4.976 kilograms, comprised of AL 5356, brass, and steel screws. With a volume of approximately 25.078 liters, the regolith captured by this system is substantial. The total width of scoops engaged is 125 millimeters. Furthermore, the coordinate of the center of gravity is: Gx[mm] = -1.213 and Gy[mm] = -0.649. I am also working on developing a balance controller and sample conduction system to complement this design.
