Robots suitable for use as a player character are more or less human shaped autonomous models with learning neural net computers. All robots are either genuine pre-war items, or are based on advanced pre-war technologies - Functional robots are extremely rare, and spare parts are hard to come by. Note that ST and HT attributes of a robot are fixed at creation - A robot's physical form can be improved only with a refit or a serious tune up. Because the robot can learn, it is possible to buy off any mental disadvantages from the racial package, either with xp-points or at creation. Even though the robots basic shape is often generally humanoid, they cannot wear unmodified rigid human armor. In the case of 'serious wounds' of over 8 hit points, only half of the damage can be repaired with work - the other half must be replaced with spare parts.
