3: The turkey is ready to eat.
3b': The turkey is ready to be eaten.
That's a very nice pair of sentences, which is indeed comparable to Coco's. The only slight difference I find with Coco's is that in (1) "repair" does not sound like an active (intransitive) verb as does "eat" if (3) is interpreted as (3a).
Let's imagine "it" is a robot in Coco's sentences. For (1) to be interpreted analogously to (3a), my feeling is that an object will be required for the meaning to be active, because "repair" is mainly a transitive verb. Otherwise, (1) will tend to be interpreted as (2) (passive meaning):
4. The robot was too badly damaged to repair anything/to repair the spaceship.
5. The robot was too badly damaged to be repaired.
