Automatons aren't designed as a playable race, and as far as I know Meph doesn't really play or design for adventure mode. I guess you're doubly out of luck.
Are you looking to DFHack to heal an existing adventurer? Or you want to mod Automatons so that in future worlds they to heal like regular organic beings? Or you want to mod a new workshop and healing reactions so that you can use AdvFort to build a machine shop that consumes resources to heal your adventurer? Probably all these things are possible if you want to mod it yourself, perhaps explain what you have in mind and someone will point you in the right directions.
