MdZ-series Droid
this series of droids was built on an advanced locomotive base, and employed auto-balance legs that allowed it to operate in any position. The design was quickly copied by both Industrial Automaton and Cybot Galactica. However, the MdZ's poor body was an inferior knock-off of the S12 design, and the overall performance of the droids suffered. Eventually, the MdZ series was discontinued.
