  Previous research has shown that the fairness and the legitimacy of a moral
decision-maker are important for people's acceptance of and compliance with the
decision-maker. As technology rapidly advances, there have been increasing
hopes and concerns about building artificially intelligent entities that are
designed to intervene against norm violations. However, it is unclear how
people would perceive artificial moral regulators that impose punishment on
human wrongdoers. Grounded in theories of psychology and law, we predict that
the perceived fairness of punishment imposed by a robot would increase the
legitimacy of the robot functioning as a moral regulator, which would in turn,
increase people's willingness to accept and comply with the robot's decisions.
We close with a conceptual framework for building a robot moral regulator that
successfully can regulate norm violations.
