KDY-4
designed and developed by the engineers at the Kuat Drive Yards, the KDY-4 series tech droid was built to construct and repair starships. Often referred to as "the builder's buddy", the KDY-4 droids were dsitinguished by their easy-going manner and usefulness on the job site. Their memory banks were loaded with schematics and blueprints, spanning those designs creating for thr Trade Federation through those of the New Republic. Kuat Drive Yards liked to say that the KDY-4 had the versaility of an R2 unit, the eloquence of a 3PO unit, and the muscle power, skill, and experience of a shipyard worker.
