When Marduk fought Gemma, he gathered the Army of the Seven Winds, which consisted of volunteers from each world shell. Throughout the main game, Doskias seems to only ever employ Chosen soldiers, while Maya ultimately ends up recruiting characters from each world shell, giving a subtle hint that she is the true savior of Septerra.
The only way to heal robots is to have Led or Grubb repair them. Sure enough, when you have them use it on enemy robots, it will work the opposite because they know what not to do.
Actually, foodstuff and normal curative magic does work on them... because they all have organic component(s) to them. However, it also doesn't work so well - because they're still mechanical.
