A Ship and Her Crew
Artificial intelligence are solely machines. They have no emotions, they are driven entirely by logic. They come to decisions and have a faster response time than Human and even Emulated Humans. There is no limit on what kind of Chasis an A.I is placed into and as such it can vary wildly. Tank treads, spider limbs, hover systems, welders, weaponry and tools. They are simply autonomous machines capable of decision making and programmed to be self aware and adaptable. While they do not have emotions, they are able to emulate emotions well to serve a purpose.
