Engineering droid/Legends

An engineering droid was one of the five major subgroups of class two droid, along with astromech droids, environmental droids, exploration droids, and sophisticated repair droids. They differed from their first-degree counterparts, the biological science droids and physical science droids, in that engineering droids worked in applied sciences, using their knowledge to solve real-world engineering and technical problems. Engineering droids worked in a variety of applied sciences, but performed poorly if forced to undertake a different job than the one they were programmed for.
