MdZ Maintenance Droid

The MdZ Maintenance Droid was a model of maintenance droids produced by TTC which used what, at the time the line was introduced, state-of-the-art articulated auto-balance legs which were copied by both Cybot Galactica and Industrial Automaton. The line's cylindrical chassis, however, was an inferior knock-off of that of Industrial Automaton's S12 droids.
