Simply Caterpillar

The drill is assembled from a base and interchangeable parts. The main part holds an 18-slot storage inventory for the drill head, and a fuel slot powers the machine. Power can be toggled from the GUI, and turning the caterpillar off pauses fuel consumption. A ride part lets a player sit on the drill while it moves.

Mining collects fallen items and moves them into the caterpillar's inventory, so blocks the drill breaks do not have to be picked up by hand. Items can also be transferred into a minecart with a chest, which is emptied when full. Players can choose which blocks are destroyed and which are kept, so water, lava, sand and gravel can be preserved to save inventory space.

Simply Caterpillar builds inside a mineshaft and places decorations similar to vanilla mineshafts by default. Its decorations can be edited, including which blocks replace gravel, sand, lava, water and air around the shaft, and which blocks reinforce the walls. Patterns can be transferred between decoration blocks, previewed, and given a name. Caterpillar is licensed under the MIT License and is open source, with public source code and an issue tracker.
