The Indestructible Digger

Pay attention to Digger, the robot. Digger can help to dig on the moon and clean the spaceship. This indestructible robot is controlled by voice. It has ears that allow it to hear. Digger has sensors that help it move around and detect danger. This robotic dynamo has two modes— dig and sweep. The dig mode is for burrowing on the moon and the sweep mode gets rid of any dust on the spaceship. Digger can charge remotely. The robot operator can also modify how deep Digger will dig on the moon. Digger can also use moon rocks for fuel. This robot can survive on rock fuel because it has obsidian in the bottom and a little of lava. When the robot “eats” a rock, the rocks are thrown into the bottom where it is dissolved into fuel.
