As of Episode 22 of the anime, Trois has been shown to have a great love for and knowledge of mechanical devices, as Honey puts it, he gets a bit obsessive "whenever he sees a woman or a machine." Because of this, he has an extensive knowledge of how machines work to the extent of being able to dismantle them within minutes to get to their inner mechanisms.
Trois has been shown to be able to construct fully-functioning weapons from scrap he finds lying around, also as seen in Ep. 22. So far, he's been shown to have created a bazooka and a flamethrower from scrap metal that he found in the room in Building 5 containing the sentry dolls.
