Brush’s body is made of heavy metals like steel to work against the atmospheric pressure of the moon while also not allowing Brush to leave the surface. The bulldozer bucket at the bow of brush is specially designed for digging and lifting the regolith. The bucket is angled so the soil does not fall out of it when being lifted to the body. The bucket is made out of a strong metal to destroy rocks and other objects on the surface of the moon so Brush does not break. Brush uses treads instead of wheels, because brush will be able to withstand the harsh environments on the moon's exterior like the craters. Brush’s body has two layers. The upper layer is a basket built to carry soil and beneath the basket is a protective enclosure which contains the electronic systems that control Brush based on the changes in the temperature.
