I have recently decided to create an exploration drone which will scan the world using geolyzer and transfer data to the server via linked card (400 blocks range is not enough far for me). However, I have faced a major problem - linked card requires tier 3 slot. I was surprised even more when I have figured out that internet card, which is more powerful for my opinion, requires tier 2 slot.
And now I am really confused: Is there at least any job in which drones are better than robots?
Sorry for my English.
