After looking at some posts and trying multiple things I found one that easly works, sorry if some1 alreadly posted this and i really forgot were i found it, so if some1 knows the original author, thank him for me.

Follow these easy steps:
1 - navigate to Documents\Paradox Interactive\Stellaris\workshop\content
in this folder there will be multiple floders with nubers like "281990\681553348" open theres folder until you find one with a zip file in it "playablerobots.zip"
2 - open the playablerobots.zip file (for safety reasons make a copy of it first)
3 - on the zip file navigate to - common > traits
4 - open "00_playablerobots_species_traits.txt"
5 - you will see this on the very first lines:

##################
# Species Traits #
##################

trait_android = {
cost = 0
modification = no
initial = no

modifier = {
pop_food_req_mult = -1.0
tile_resource_food_mult = -0.5
pop_environment_tolerance = 0.1

6 - on the line were it is "pop_environment_tolerance = 0.1" change the value to 1.0, it should be like this "pop_environment_tolerance = 1.0"
7 - save and close the txt, if a message appears asking if you want to update the zip file, click yes.

This should make robots have +100% habitability

HAVE FUN!
