The Rolling Slider (RASSOR DRUM)

This is my second design submission for the competition, with The Malayan Tiger being my first entry. My focus has shifted towards simplicity and maintenance capabilities this time around. This design relies heavily on sliding physics. I anticipate the soil to slide into the drum, filling it nearly 95% of its internal volume. During loading, the soil will slide into the drum, rotate, and eventually fall into a holder attached to the drum – shaped like a snail – which will secure the soil that has flowed in. The main collector drum is divided into segments by connection panels, with these panels sitting between each section. In case of unloading, the segments should be able to separate easily. When holding the soil, the drum is designed to remain upright without the intake pointing downwards, relying on gravity's effect to keep the soil inside. Gravity was modeled at 1.62 m/s^2 for lunar conditions. My design weighs approximately 12.618 kg, using Carbon Fiber with a modulus of 398 GPa. Simulations demonstrate how the drum collects soil quickly, and they were conducted under lunar gravity conditions.
