You can only have two bots out at once, though.
Ah, one is plenty. By the time I finish exploring an area or clearing it out, my bot is usually done and then I go pick it up and deploy to a new area.
So far, I haven't needed more than one... But I keep forgetting that I have it so I don't use it much. When I'm out of tungsten though, I use it for supplies!
