Its like stone age mixed with bots.And yes the recharge station is not in the stone age.But alot of people saying "In the next update we might get in to bronze age"so its like a age thingy that evolved and add new items to the game.Anyways theres still a thing that i do when a robots has no power i assigned a "Medic" to help the workers out but i need atleast 3 to 5 medics to make the robots get recharged since they well you know they run out of power pretty fast for the BWB[Basic Worker Bot]and for the steam bots which is quite suprising for me.It needs logs like ALOT of them so thats the same i do to them but the BWB is the one who is gonna give them the log to keep them in fll working order anyways that alot that i did say lol.So yeah thanks for the reply Denki!
