This should happen in several steps, where the user and his turtle will have more and more abilities. The idea of the mod is, to let young ( and older) Minetest builder become a programmer. I'll later collect a list of all the mods that have nearly the same idea. May be some of the ideas and solutions can be used here in the TurtleMiner mod.
In fact there are many mods that have a similar idea but none if them has been finished. I present the mod as hopefully other users are interesting in being a part of it.
It does not have the full abilities and is far away from the wanted state.
