RAC v2.0

This is an updated version of my initial submission, boasting the same fundamental operating mechanism as its predecessor while incorporating several enhancements to enhance its functionality. These updates include: 1. The geometry of the shovel has been revised to guarantee that sand effortlessly falls into the drum in low-gravity environments. 2. An angular contact bearing SKF 3204-A was integrated to counteract the moment load on the drum's shaft. 3. The cam clutch bearing was modified to accommodate the increased dimension of the drum's shaft. 4. The drum's shaft and its structure were re-engineered to provide greater rigidity under full load conditions. 5. The flange that connects the RASSOR main shaft and the bucket has been revised. This updated version boasts a significantly improved load capacity, measuring 32.6 litres, which in turn boosts the fill ratio to an impressive 56.9%. Aluminium 6061 remains the material of choice for the overall design, with the added benefit of reduced weight, now standing at 4.6kg. A link to a straightforward demonstration video has been provided, showcasing the shovel's ability to transport sand to the drum opening at the top and continuously fill the drum efficiently. Further refinement of the shovel geometry is recommended to achieve peak performance in low-gravity environments. I extend my gratitude to all commentators who have contributed valuable recommendations to enhance this design. Link to my initial submission: Regolith Advanced Collector (RAC)
