NASA RASSOR Challenge · 模型 267801
This is an entry for the NASA RASSOR Challenge. Description of drum: Sixteen scoops were mounted on the surface of the roller for digging. It collects the dirt as the drum turns clockwise, and the flaps between the shovel and the drum keep the dirt contained. When the collection is complete, the drum can be turned counterclockwise and the dirt will fall from the scoops eliminating the need for a separate unloading mechanism. All items are made of Carbon Steel for durability, lightness, and resistance to abrasion. The suggested assembly method is electrical resistance welding.
