caterpillar is a mod that allows us to use mechanical drills or tunnel boring machines, with which we can create tunnels and collect minerals in an automated way. The mod allows us to create several machines that can be assembled into a single machine that allows drilling, picking up and decorating the tunnel.

One of these machines drills, earth and rock, while another collects all the materials we have drilled, and finally a machine that places wooden structures and torches to decorate the drill galleries (as in the caves), at the time which lays tracks that we can then travel in wagons.
