Thalia is a lunar robot that collects lunar regolith in two ways: by using the clinginess of lunar dust to collect it, and by shovels attached to the base of the wheel supports. The shovels store their collected dust into the center of the heavy wheels. The wheels can then retract when the wheel storage is full, and send the regolith into a central balancer, an old-fashioned scale. It can be evened out by extra sand, though mental calculations are needed. There is a display screen to show all needed info about the central balancer. Thalia is solar-powered and wiring connects all mechanical parts to other wires or directly to the solar panel. Thalia makes sure it doesn't fall off the side of a crater, through a retractable support system. Thalia is my robot I put my heart into, and I worked hard to make sure the constraints were fulfilled.
