Copy the aesthetics of a human.
Let it decide the value of things that are subjective to it's survival.
Place objective rules. (May not murder or perform non-consensual acts)
Give it similar, but more durable inner mechanics.
Give it the ability to understand how to survive in both a hostile and non-hostile environment.
Make sure it understands the value of communication with human society.
Make sure it knows the lyrics to every Journey and Led Zeppelin song.
Give it a birthday.
Truly, nothing could go wrong.
