The Fisherman Android already exists in Nations.

but it doesn't work

nor do the others except for the farmer and butcher

They are already there iirc, and, if they don't, there is no need for them anyways

the fisher is very useful but the other ones not so

the fisherman android works perfectly fine
i have one making fish for me 24/7

Fisherman Android has a % of sucess for each time it "fishes". Also Miner and Lumberjack would allow automatic farms for resources that are much needed for the fundamental economy.

The Fisherman and Butcher are already in SF Nations. However, for the case of the Miner and Woodcutter, there is ways to farm them via none automated ways.

I can't get the fisherman to work for me and I haven't tried the others

On the wiki it says that fisherman androids are disabled in nations
