Mining Turtle

Mining Turtles are upgraded versions of Turtles from ComputerCraft. When programmed correctly, they can mine in a square shape until they are full.

A program for a mining turtle could look like this: Excavate 5

This program would tell the turtle to mine a cube with dimensions of 5 blocks on either side, and the turtle would mine these layers of 5 * 5 until it ran out of space and would return to the surface.

Another use of the mining turtle is of entertainment, a command that one can give is

dance

The turtle then states "Preparing to get down" The turtle will then move in such a fashion it could be considered dancing. It will continue to "dance" until anything is typed into the robot again.
