Abstract
As the field of robotics matures robots will need some method of
displaying and modeling emotions. One way of doing this is to use a human-like
face on which the robot can make facial expressions corresponding to its
emotional state. Yet the connection between a robot s emotional state and its
physical facial expression is not an obvious one: while a smile can gradually
increase or decrease in size, there is no principled method of using boolean
logic to map changes in facial expressions to changes in emotional states. We
give a philosophical analysis of the problem and show that it is rooted in the
vagueness of robot emotions. We then outline several methods that have been
used in the philosophical literature to model vagueness and propose an
experiment that uses our humanoid robot head to determine which philosophical
theory is best suited to the task.
