NASA REGOLITH - Anket Vispute, Vighnesh Raman

We dove into the design of the current NASA RASSOR bot's drum, brainstorming ways to improve it. The design we came up with for the NASA RASSOR aims to achieve maximum fill ratio possible. This is achieved through hinged flaps on the rear side of each entrance, ensuring no collected regolith escapes after 50% of the drum is filled. Gravity and centrifugal force cause the hinges to move, closing them when collecting regolith to prevent pre-collected material from falling off. As the drum turns, the flap moves to a stable position, opening the entrance for collected regolith to enter. To remove collected regolith at the end point, the drum is rotated with the actuator above and the hinge opened up, allowing regolith to exit through the spout in the next rotation. This design surpasses others as it prevents collected regolith from falling out of the drum without our control.
