MN-2E
a series of maintenance droids produced by Industrial Automaton, originally at the request of the facilities managers of the Imperial Palace on Coruscant. The Empire later used one of them in concert with the Ch'hala tress of Coruscant to form the Delta Source. Conical in form, the MN-2E was a tread-driven automaton equipped with sensitive manipulators that can effect detailed or delicate repairs. Note that The Essential Guide to Droids indicates that the MN-2E was equipped with a repulsorlift engine for locomotion. They also had special magnifying visual sensors, and had a variety of cutting and collection apparatus, as well as an internal waste-recycling system.
