Wholesome stories with a robot protagonist?

I’m looking for a book that has a robot for a main character, NOT one that looks like a human, I want a proper robot made of metal and circuitry.

Story wise, I’d prefer something at least a little wholesome, with little-to-no action.

Something about a robot seeking a purpose, learning about the complexities of human behavior or even something akin to slice-of-life would be ideal.

Bonus points if it involves nature!!
