  Empirical studies of personal autonomy as state and status of individual
freedom, security, and capacity to control own life, particularly by
independent legal reasoning, are need dependable models and methods of precise
computation. Three simple models of personal autonomy are proposed. The linear
model of personal autonomy displays a relation between freedom as an amount of
agent's action and responsibility as an amount of legal reaction and shows
legal equilibrium, the balance of rights and duties needed for sustainable
development of any community. The model algorithm of judge personal autonomy
shows that judicial decision making can be partly automated, like other human
jobs. Model machine learning of autonomous lawyer robot under operating system
constitution illustrates the idea of robot rights. Robots, i.e. material and
virtual mechanisms serving the people, deserve some legal guarantees of their
rights such as robot rights to exist, proper function and be protected by the
law. Robots, actually, are protected as any human property by the wide scope of
laws, starting with Article 17 of Universal Declaration of Human Rights, but
the current level of human trust in autonomous devices and their role in
contemporary society needs stronger legislation to guarantee the robot rights.
