(Click to zoom) Made a bunch of mining robots, each with different functions. (in order :) Picker - Their job is to grab freshly mineral fragments from the Driller, before storing them in their backpack. Once full, they either dump their storage in minecarts, or Stockers. Stocker - Their job is simple : store minerals or liquids from mining sessions. Their bulky and bullet proof glass allows their loot to be well protected. Mine Supervisor - Their job is to manage the mines, calling for reinforcement if they're attacked or if more valuable than expected are found. They also coordinate the troops for them to be as efficient as possible. Buster - Their job is a bit small, as they mostly just use their nitroglycerine to blow up caves and mountains, creating entrances for the others to mine through. Crawler - Their job is similar to the Stocker's, except they pull railcars. While they can't store as efficiently than Stockers, they can travel at a way faster speed, and are much deadlier, allowing them to defend their loot more efficiently. Scout - They're basically just flying security cameras. That doesn't mean they're not important. Them, and the Mining Supervisor both work together to make sure there's nothing wrong during the mining session. Driller - Their job is probably the most important, as they are the ones actually mining the minerals. As simple as that.
