Whilst the enhancement system is a interesting idea, I think doing it in a menu with stats takes you out of the immersion / gameplay loop.
Given the fact that we're a robot i think it would be much cooler to enhance our caretaker by obtaining actual upgrades. "Insert robots meme Upgrades people upgrades! here"
Each enhancement lends itself well to a robot styled upgrade.
Vitality: scarf
Haulmastery: Legs
Improved hydraulics: Arms
Engineering: Eyes
Pressure: Head
Scrapper: Hands
Battery: Back

you could then maybe give them visual differences ontop of evolving your robot to be more high-tech. You could also then scatter these upgrades around the map to give more reason to explore the non story outposts. with more difficult outposts giving the better upgrades. or obtaining a "plan" so you could craft the upgrades yourself.
I think this kind of enhancement system would be better for the game and the gameplay loop of explore + gather + craft, than a "Boring" menu with stats..
