A roboticist was a type of engineer that specialized in the creation of droids. Morgan Katarn, a key figure in the Alliance to Restore the Republic, became a roboticist through independent learning and subsequently designed his own versatile droid known as WeeGee.
A skilled roboticist possessed the capability to integrate components from one droid into another and calibrate them precisely; for example, when 8t88 suffered the loss of his arm, he withdrew to Sulon, where he acquired a replacement arm from a different 88 unit and attached it; due to the absence of a roboticist, the droid performed the installation himself.
