Name:Voldrum Series(vul drum)
A high-speed rolling robot in nearly constant motion. Equipped with two large guns for attacking from a distance. It is equally efficient at close-quarters combat.
This version of the Voldrum has a weaker hull then the standard model, rendering it vulnerable to rapid-fire weaponry.
A late advance in Voldrum technology featuring freezing projectiles. Its pulse-tube crycoolers are extremely susceptible to high temperature impact.
Another modification of Voldrum technology, its high operating temperature causes reduced defensive capability against subzero weaponry.
