Z7 series

The Z7 series was a line of construction droids. Manufactured by Structgalactis, Inc., it was designed for such heavy work as clearing fields, digging ditches, grading terrain, and putting up new buildings. It was one of the first models equipped with a set of frictionless omnidirectional treads ever to be commercially deployed. Shaped like a cube whose sides were 3 meters in length, a Z7 unit had two symmetric arms that could be fitted with various attachments such as shovels, power lifters, hooks, hoes, wrecking rams, and stack manipulators.
