You can domesticate some creatures...but you can also create a creature just for help you carry stuff. These big tame creatures carries a good amount of resources from one outpost to another. We know you love robots, but they need energy and carry few items. They aren't that fast as flying robots, but with some of these beasts you can carry large amounts of stuff and you just need to feed them . They works with the same mechanics as the robots, so you don't need to learn again some logistics.
