850.AA Maintenance Droid
designed and manufactured by Publictechnic, this immense droid was developed to handle the maintenance needs of urban areas. It has an internal storage bay, which could hold several smaller droids which could perform finer maintenance operations. These immense, automated vehicles stood over thirteen meters in height, and had three separate stories of storage and operation centers. The 850.AA hovered just centimeters off the ground on powerful repulsorlift engines, and had an energy-conservation system that allowed the 850.AA to operate for weeks at a time without repowering.
