Project Toothless

The "Outer.stl" model showcases Toothless' outer design. Meanwhile, the “Inner.stl” reveals its intricate inner workings. By examining the Outer.stl closely, you can notice two distinct shovel sizes digging into the Regolith. When rotated clockwise, the smaller shovel enters the moon's surface first, followed promptly by the larger, steeper shovel. This strategy aims to achieve a sharper angle of attack, allowing for more efficient penetration into the lunar surface. The second shovel, however, focuses on scooping up more Regolith as the drum delves deeper into the moon's surface. Its broader design also increases efficiency by mirroring the 45-degree angle used in throwing a ball for optimal distance. Upon inspecting the “Inner.stl”, four curved inverted "L" shapes become apparent. These structural elements guide the Regolith effortlessly into an innermost chamber featuring a square with triangular grooves that catch and hold the material securely. As the drum rotates clockwise, these curved sections capture even more Regolith. To expel the Regolith, the drum must be turned counterclockwise, where its curved design facilitates a smooth release into the desired location. The "L"-shaped structure's hook ensures that all Regolith is stored when rotating clockwise and extracted when turning anti-clockwise. The shovels' sharp edges enable effortless excavation of the Regolith, while the circular shape allows for seamless Regolith transfer to its intended destination.
