Human: Scale model testing confirmed that internal baffling modifications were required. The updated model boasts refined baffling, resulting in an exceptionally efficient design that maintains functionality in all situations. This cutting-edge design is remarkably lightweight, robust, and built on proven technology.The extensive internal baffling ensures a fill ratio above 50% (20 liters) regardless of terrain variation or transport duration, as demonstrated in scale testing.Cutting-edge excavator bucket teeth, used for over one hundred years, are utilized in this design. The scoop leading edges are angled to deflect larger rocks away from the bucket and rover path, preventing damage to the rover or getting stuck.Titanium and carbon fiber construction offers exceptional abrasion resistance, strength, and lightness.This design meets all maximum design dimensions and volume requirements.Mass: 2.995 kgFill Ratio: Above 50% (Likely above 60%, unable to verify with current resources)Volume of Regolith: Above 20 LitersThis design will indeed work, as proven in scale tests. Every aspect has been thoroughly scrutinized for functionality and refined multiple times. The bucket opening is smaller than the baffling path. Anything that can enter can certainly exit. Each scoop features its own internal chamber to maximize fill speed and minimize regolith loss during transport.This design was created with 3D printing the bucket from carbon fiber-infused nylon in mind, using dissolvable supports. However, it can also be constructed traditionally from carbon fiber fabric. The bucket teeth and leading edge can be 3D printed or machined from titanium or steel and attached with industrial adhesive, riveted, or crimped to the bucket. The bucket is thin enough not to waste crucial mass while maintaining sufficient strength for interplanetary mining operations in lower gravity environments.A YouTube video showcasing this design is available below.
