Sweeper v1

Sorry about that sloppy presentation! The real focus here is on getting those drums to load and unload fast in low-gravity conditions. Now, I know what you're thinking - "what's so special about these drums?" Well, let me tell you: the inside diameter stays constant, and the scoops are attached outside without altering the inner space. Inside the drum, there are sweepers that rotate independently of the buckets and work like a brush/scraper to grab whatever comes from the scoops quickly. These sweepers spin 20% faster than the drums themselves, which is why they can deploy soil pieces almost effortlessly in low-gravity conditions. But, as you can see from the figures, there are some issues at play here too. The rotations of both drum and sweepers will cause some buckling problems, adding to the original torsion issue with Rassors. Not to mention, tougher ragolith pieces might get jammed between the sweepers and drum, so we need to come up with a solution for that. One idea is to change the outer ends of the sweeper to a metal brush, which will prevent future problems like minor ragolith pieces getting stuck between the drums and sweepers, causing bent sweepers or scratched drums. And then there's still the issue of operators constantly inputting data. The drum design consists of 3 slices, each 120mm long and 450 mm in diameter, with 3 scoops spaced evenly apart from each other. Each slice has a total diameter of 450mm, scoop width of 120mm, and a total length of 360mm, giving us an approximate volume of 38.5 L. Sorry again about the presentation - let's focus on getting this design right!
