so that no individual robot may become like Andrew. Meanwhile, Andrew, with his new body, decides to study robobiology – the science of organic robots like himself. Andrew begins to design a system allowing androids to eat food like humans, solely for the purpose of becoming more like a person. After Paul's death, Andrew comes to U.S. Robots again, meeting with Alvin Magdescu, Director of Research. He offers U.S. Robots the opportunity to market his newly designed prostheses for human use, as well as his own. He successfully has the digestive system installed in his body, and plans to create an excretory system to match. Meanwhile, his products are successfully marketed and he becomes a highly honored inventor. As he reaches 150 years of age, a dinner is held in his honor in which he is labeled the Sesquicentennial Robot. Andrew is not yet satisfied, however. Andrew decides that he wants to be a man. He obtains the backing of Feingold and Martin (the law firm of George and Paul) and seeks out Li-Hsing, a legislator and chairman of the Science and Technology committee, hoping that the World Legislature will declare him a human being. Li-Hsing advises him that it will be a long legal battle, but he says he is willing to fight for it. Feingold and Martin begins to slowly bring cases to court that generalize what it means to be human, hoping that despite his prosthetics, Andrew can be regarded as essentially human. Most legislators are still hesitant due to his immortality. The first scene of the story is explained as Andrew seeks out a robotic surgeon to perform an ultimately fatal operation: altering his positronic brain so that it will decay with time. He has the operation arranged so that he will live to be 200. When he goes before the World Legislature, he reveals his sacrifice, moving them to declare him a man. The World President signs the law on Andrew's two-hundredth birthday, declaring him a bicentennial man. As Andrew lies on his deathbed, he tries to hold onto the thought of his humanity, but as his consciousness fades his last thought is of Little Miss. He sees her at the foot of his bed welcoming him to the eternal place where humans go after they die and he understands why he has sought to be human and that he has succeeded in becoming human.
