"The point sticks in your head: physics rules. Virtue does not triumph unless the physics allows it."

There's a lot of work to be done on the moon to prepare it for human habitation. What tools will we need?
| To shift those rockslides, one would have to import moondozers across the Sea of Thirst, and import whole shiploads of gelignite to blast a road through the mountains. |

Clarke doesn't give us much to work with except the basic term. By the time you get to the future outlined in Niven and Pournell's Oath of Fealty (1981), you didn't even need to be on the moon to operate one - see the entry for telepresence bulldozer.
NASA engineers take it one step further - autonomous dozers. They've been playing with the idea of using bulldozers - on Mars. Here are some Bulldozer Rovers at play.

"If water sources, such as hot springs, layers of ice or groundwater reservoirs are discovered on Mars, a network of these rovers could conduct scientific investigations and excavate the site piece-by-piece, just as humans would on an archeological dig," said Brian Wilcox, supervisor of the Robotic Vehicles Group at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "Rovers like these may also play a role in establishing a space outpost for eventual human occupancy. They may be used to create buried habitats or utility trenches and to excavate resources to support life."
