UrbanBot was a prototype robot created after the success of the first armored robot. This prototype was designed for combat in enclosed or busy areas. Several of the first prototypes experienced an error aboard the transport ship. After the functioning robot defeated the malfunctioning robots, the cargo ship was abandoned. One of the robots were salvaged and later this model of robot was used to attack an alien cargo ship. After the robot proved its inefficiency in battle, mass production of this model was cancelled. The few robots of this type that were manufactured remained in sercive until 2117 A.D.
